Killing the LSTM: Why DANI is Pivoting to a Spiking Neural Network

After some extensive research and a few hard encounters with hardware reality, I’ve made a major architectural decision regarding DANI's brain: I am completely ripping out the LSTM neural network and replacing it with a Recurrent Spiking Neural Network (RSNN).

Given my recent enthusiasm for the LSTM architecture, this will probably come as a surprise to anyone following along. However, I have my reasons, and as usual, they come down to math, metal, and thermal throttling.

What is wrong with LSTMs and the Traditional ANN?

Traditional Artificial Neural Networks (ANNs) are fantastic at what they were designed for: probability scoring. They allow us to simulate decision-making using massive matrix calculations mixed with a healthy dose of calculus.

But beneath the hood, they are brute-force mechanisms.

When a traditional ANN is fed data, that data cascades through every single neuron in the network. Even when a neuron has a zero value, the CPU still dutifully performs the mathematical operation of multiplying by zero. If a network has a shape of 10 inputs, 10 outputs, and 5 layers of 12 neurons each, that is 816 floating-point calculations just for one single feed-forward pass. If you start adding in simple recurrence, we are immediately up to 1,488 calculations.

Now, scale this up to something that would actually be useful for DANI. We need at least 100 inputs and about 64 outputs. With hidden layers of around 125 neurons each, we jump to 150,375 calculations per pass. To achieve an LSTM architecture, we can estimate the computation to be roughly four times that: over 600,000 calculations per tick.

As you can see, this grows exponentially. More importantly, it keeps the CPU running permanently hot. Don’t forget, DANI is powered by a Raspberry Pi 5. There is no GPU offloading here. I did manage to get DANI’s LSTM operating at 10Hz with 3.5 million parameters, but it required the Pi 5 to do absolutely nothing else, running flat-out at 100% utilization. DANI's brain was essentially doubling as a space heater, even when he was just "dreaming."

Once you add my simulated hormone system into the mix, the compute overhead goes up even further. I was basically following the same brute-force model that the big AI companies use, just without the luxury of a multi-million dollar server farm.

And then there is the training. To train an ANN of this style requires layer-by-layer calculus (backpropagation). This is heavy, blocking work. It takes a considerable amount of time, meaning we simply cannot train the network in real-time on anything substantial.

The Elegance of the Recurrent Spiking Neural Network

The architecture of an RSNN is topographically similar to other neural networks, but the execution is fundamentally different. It mimics biological reality much closer.

Instead of passing continuous floating-point numbers, each neuron has a membrane potential. As it receives signals from upstream neurons, that potential increases (or decreases, if the synapse is inhibitory). The neuron does absolutely nothing until that potential reaches a specific threshold. Once it hits the limit, it fires—or "spikes." And it spikes at a binary full power. The neuron then resets, either dropping to zero or subtracting the threshold from its current potential.

If a neuron doesn’t reach the threshold, it doesn’t spike. Period.

This means we only need to calculate the pathways for neurons that actually receive a spike. The computational reduction is staggering. The general consensus in the field is that for any given signal, only 5% to 10% of a spiking network is active, compared to the 100% density of a matrix-style network.

Training also becomes radically simpler. We only need to reinforce or weaken the synapses of the pathways that actually fired (a process akin to Spike-Timing-Dependent Plasticity). We apply a localized effector to those specific connections—no massive, network-wide calculus required.

But here is the real kicker for a systems engineer: an RSNN allows us to completely ditch floating-point math. By using integer mathematics and clever bit-shift operations (which are essentially free in terms of CPU cycles), we can completely bypass the messy, cycle-heavy floating-point multiplications.

How does this help DANI?

Obviously, DANI will not have to run so hot. If he has a quiet mind, the network will physically go quiet. When DANI rests, he will literally be saving power. By utilizing temporal calculations, we can also train him in real-time with near-zero impact on the system.

Furthermore, DANI’s brain becomes an event-driven architecture rather than a strict polling loop. Instead of processing rigidly on a timer, he will think and react in time with the world around him.

I will still be using the hormonal system I designed, but the key difference is how it integrates. The effective values of the hormones will now directly modulate the firing thresholds of the neurons. This allows his "moods" to physically alter the state of his brain and affect his behavior, even if his underlying memories remain unchanged.

I suppose I had better be nice to him.

Rethinking Asimov’s Laws


This pivot finally allows me to revisit a question I was pondering a while back: How do we encode Asimov’s Laws into an AI?

The answer is: we don’t. It’s as simple as that. We don’t hardcode the laws; we teach them.

By running an RSNN that learns in real-time through stimulus and reinforcement, the laws can become an emergent part of his personality. He will understand that hurting people is bad and that following human orders brings a reward, not because a line of code forces him to, but because his synapses have shaped themselves around those experiences.

So, I guess I really am going to have to be a parent to a robot.

Major Milestone: Skink Has Officially Bootstrapped!

Woohoo! It’s time for a long-overdue update on the language powering the future of DANI.

We just crossed a monumental threshold with Skink: it is now officially bootstrapped!

For anyone unfamiliar with compiler development, bootstrapping means that the Skink compiler can now compile its own source code. From here on out, all future versions of the Skink compiler will be written in Skink itself. It’s a huge rite of passage for any programming language project, and seeing it actually work after so much foundation work is insanely satisfying.

Where Go Fits In (For Now)

The handover
Now, does this mean I’m throwing Go out the window today? Not quite!

Go has a proven, rock-solid track record, and I’ll be keeping it around for prototyping work. Whenever I want to test out an idea quickly and I’m not sure if Skink is quite ready to handle the heavy lifting yet, Go gives me a reliable safety net.

However, the long-term vision hasn't changed: eventually, I plan to fully commit to Skink for almost all development across my projects, experiments, and research.

The Road to Skink 1.0

While bootstrapping is a massive step forward, we aren't quite at version 1.0 just yet. To earn that release tag, Skink needs to hit a few crucial targets:

  1. Cross-Platform Support: Clean cross-compilation across Windows, macOS, and Linux.
  2. Architecture Support: Full targeting for both x86 and ARM architectures.
  3. Embedded Target Transpilation: The ability to compile (or at least transpile down) to low-power platforms like the K210, ESP32, and standard Arduino C/C++.
  4. Direct Hardware I/O: First-class hardware abstraction libraries for lower-level protocols—specifically I2C, SPI, GPIO, and related interfaces.

Acceleration, Compute, and Graphics Backends

Beyond microcontrollers and standard CPUs, getting high-performance compute and neural inference support hooked up is high on the priority list.

  • CUDA Support: I still need to get CUDA fully enabled and tested. Because of my current local setup, this will likely require either acquiring new dedicated NVIDIA hardware or setting up a cloud-based VM for build and test pipelines.

  • Vulkan & AMD: My main local system currently relies on Vulkan to run LM Studio, so a Vulkan compute backend is high on the radar as a viable cross-vendor path. I'm also looking closely at AMD’s libraries (ROCm/HIP) to ensure broad hardware compatibility.

It's a lot of moving parts, but watching the architecture take shape piece by piece is incredibly rewarding.

Bringing It Back to DANI

So, why go through all the trouble of building a custom language from scratch?


It all comes down to DANI. My goal has always been to have a single, unified language capable of bridging every layer of DANI’s stack—from high-level logic and neural compute all the way down to real-time bare-metal sensor and actuator control. Skink is the key to making that happen without juggling three different language ecosystems.

Speaking of DANI, there have also been some fascinating developments regarding his neural network architecture recently... but I’ll leave you hanging on that for now and save the deep dive for the next post!

Stay tuned!

Introducing Skink-lang: Elegant Systems Programming for AI & Robotics (or, How to Stop DANI from Eating the Skirting Boards)


Over the last thirty years, I’ve worked across a sprawling landscape of technologies—from writing Go, C#, Pascal, Swift, and C, to orchestrating massive cloud pipelines, down to micro-managing registers on bare-metal microcontrollers.

But lately, my time has been dominated by a very specific, highly opinionated, and occasionally cooperative localized AI agent: DANI.

If you've been following my previous posts, you know DANI has transitioned from an LSTM-based cognitive core into a physical, moving entity. And that is where the real-world engineering headaches began. Every time you start a new robotics or physical AI project, you are forced to make a compromise that feels like choosing between a kick in the shins or a poke in the eye:

  • The C/C++ Extremity: You get deterministic, blazing-fast performance on microcontrollers, but you sacrifice developer ergonomics, modern package safety, and swift prototyping. Writing raw $C++$ register manipulation code sometimes feels like trying to perform laparoscopic surgery on yourself with a rusty spoon.
  • The Python Extremity: You get instant access to rich AI primitives, neural networks, and expressiveness. But you inherit bloated virtual environments that take up more disk space than the library of Alexandria, and unpredictable garbage collection (GC) latency. When DANI’s control loop is running at $100\text{ Hz}$ and the Python garbage collector decides to take a mandatory three-millisecond tea break, DANI doesn't stop. She gracefully, but deterministically, plows straight into the skirting board.

I got tired of choosing between developer speed and hardware execution safety. I wanted a compiled language built specifically for low-level systems hardware, high-throughput concurrent event streams, and native AI execution.

So, I built Skink-lang.

What is Skink?

Skink is an LLVM-backed, statically-typed systems programming language designed from the ground up for the modern era of intelligent automation. It blends the tight, expressive syntax of modern languages like Swift with the lightweight concurrency model of Go, leaving behind the runtime bloat.

To save you from the nightmare of modern package managers—where doing a pip install on a single helper utility somehow downloads half the internet and a bootleg copy of Doom—Skink comes with a rich, "batteries-included" standard library right out of the box.

As a Skinker (yes, that is our official title now), you get native access to:

  1. Automatic Reference Counting (ARC): Predictable, deterministic memory management without "stop-the-world" garbage collection pauses. This is a non-negotiable requirement when you are driving physical motors or processing high-frequency sensor telemetry.
  2. Lightweight Concurrency: A native spawn keyword that allows you to spin up millions of concurrent tasks with near-zero overhead, communicating cleanly via typed channels.
  3. The Rules Engine: A compiler-optimized reactive rules engine that lets you define declarative behavioral overrides that monitor variables in the background. It is perfect for saying, "I don't care what the neural net is thinking; if we are $15\text{ cm}$ away from a wall, hit the brakes."
  4. Native Tensors & ML Cores: Multi-dimensional arrays built directly into the type system via std/tensor, complete with matrix operations, activation functions, neural layers, and hooks for CUDA acceleration and llama.cpp (std/llm). DANI can run local inferences natively, at maximum speed, without needing a dedicated power plant or $16\text{ GB}$ of RAM.
  5. Model Context Protocol (MCP) & MQTT: Built-in support for turning any hardware endpoint into an instantly discoverable AI tool with SQLite (std/db) and edge-to-cloud messaging (std/mqtt) ready to go.

Under the Hood: Preventing a DANI Catastrophe

To see what "skinking" actually looks like, let's write a syntactically valid program based on the current Skink manual.

The following script concurrently polls a physical distance sensor via GPIO, pipes the measurements to our main execution block using channels, evaluates safety overrides in a background ruleset, and processes the inputs through a linear neural network layer to calculate motor outputs:

module main

import "std/gpio"
import "std/time"
import "std/tensor"

// 1. Declare global state variables (accessible by the ruleset)
var current_distance: float = 100.0
var motor_speed: float = 0.5

// 2. Define a reactive ruleset for safety overrides
ruleset SafetyOverride {
    rule collision_warning when current_distance < 15.0 {
        action: trigger_emergency_stop()
        priority: 1
    }
}

// Helper function called when the rule fires
fn trigger_emergency_stop() {
    motor_speed = 0.0
    print("SAFETY OVERRIDE: Obstacle detected! Distance: {current_distance}cm. Braking.")
}

// 3. Concurrently poll the hardware sensor in a background task
fn sensor_loop(ch: chan<float>) {
    err := gpio.Setup()
    if err.message != "" {
        print("Failed to initialize GPIO: " + err.message)
        return
    }

    // Bind to BCM Pin 17 (e.g., our sensor input pin)
    sensor_pin := gpio.PinFactory(17)
    sensor_pin.SetInput()

    while true {
        // Mocking a physical sensor read for this demo loop
        // In physical deployment, you'd calculate raw voltage pulses here
        measured := 12.5 
        ch <- measured
        time.SleepMs(10) // Poll at 100Hz
    }
}

// 4. Main Entry Point
fn main() -> int {
    sensor_chan := make(chan<float>)

    // Spawn our lightweight background polling loop
    spawn sensor_loop(sensor_chan)

    // Activate our safety ruleset background thread
    safety := SafetyOverride{}
    safety.start()
    defer safety.stop()

    // Initialize a linear neural network layer [input_features: 3, output_features: 1]
    layer := tensor.NewLinear(3, 1)

    // Run our control loop for 100 iterations
    for i := 0; i < 100; i = i + 1 {
        // Block until next sensor reading arrives
        current_distance = <-sensor_chan

        // If we are in a safe zone, let the tensor neural layer drive
        if current_distance >= 15.0 {
            input := tensor.Zeros([1, 3])
            input.Set([0, 0], current_distance)
           
            output := layer.Forward(input)
            motor_speed = output.Get([0, 0])
           
            print("Processing... Current motor velocity: {motor_speed}")
        }
    }
    return 0
}

Notice how neatly this handles the classic embedded AI problem. The concurrency model lets you poll hardware safely on separate execution threads without blocking the main loop, while the native ruleset watches the critical state variables and takes action within milliseconds if a threshold is breached—guaranteeing deterministic safety constraints before DANI can do any structural damage to the house.

Where Skink-lang Goes From Here

Currently, the compiler is bootstrapped in Go, using an LLVM backend to output highly optimized native machine binaries targeting both Linux and Windows corporate environments. Because there is no heavy runtime or garbage collector, a compiled Skink binary running an active inference loop can comfortably squeeze inside less than $128\text{ KB}$ of RAM.

But this is just the beginning. The roadmap ahead includes:

  • Direct Single Board Computer HAL: Expanding the standard library to map hardware registers and pins natively (such as on the Raspberry Pi 5) with zero external C-bindings.
  • Self-Hosting: Rewriting the Skink compiler entirely in Skink itself, proving the language's capabilities to handle massive, complex systems-level software natively.

I’m incredibly excited about what this language makes possible. DANI is already running much cooler, much faster, and with a significantly lower skirting-board collision rate.

It is time to stop fighting the plumbing.

Let's get skinking!

Let me know your thoughts on the syntax, and what features you'd like to see added to the compiler next!

The Sledgehammer and the Hazelnut: Why DANI Isn't Using an LLM

I have a confession to make. I’ve broken my own rule.

When I set out to build and program DANI, one of my core principles was to ensure he learns primarily from experience. The goal has always been emergent behavior through his neural architecture, with as little "hard-coded" logic as possible. But as I’ve delved deeper into the complexities of human interaction, I’ve found one area where I feel a departure is justified: Natural Language Processing (NLP).

The LLM Dilemma

The LLM Sledgehammer
Early on, I toyed with the idea of giving DANI a dedicated board specifically to run a Large Language Model (LLM). It seemed like the modern solution, but the more I looked at it, the more the red flags started popping up.

First, there’s the cold, hard reality of the budget. I’ve managed to keep the total cost of DANI—parts, boards, and all—under £500. Adding a high-spec NPU or a secondary board capable of running something like Llama or Gemma would have blown that goal out of the water.

Then there’s the physical engineering. Space is at a premium inside DANI’s chassis. While I probably could have squeezed another board in there, I’m increasingly conscious of airflow. The last thing I want is for DANI’s "brain" to thermal throttle in the middle of a conversation.

But most importantly—and this was the dealbreaker—is the issue of personality. If I use a pre-trained model like Qwen or Llama, I’m essentially importing someone else’s bias and conversational style. These models are fine-tuned to be helpful assistants; I want DANI to be DANI. Using a massive, multi-billion parameter model just to parse a "hello" felt like using a sledgehammer to crack a hazelnut.

The Go-pher’s Path to Understanding

Instead of the LLM route, I’ve built a custom natural language module using standard NLP libraries for Go. It’s lightweight, it fits within our existing hardware constraints, and it gives me the control I need.

I’ve added two critical features that an off-the-shelf LLM wouldn't handle the way I want:

  1. Sentiment Assessment: By using established sentiment modules, DANI can now perceive whether he is being praised or scolded. This feeds directly into his hormone levels. If I’m happy with his performance and tell him he's done a good job, his "positive" hormones will rise, reinforcing that behaviour in his training.
  2. Simplified Context Awareness: I wanted conversations to feel natural. If I ask DANI, "Where is he?", he needs to understand that "he" refers to the last male person we discussed. Similarly, "Go there" should resolve "there" to the last location mentioned. This kind of stateful awareness is vital for a robot that exists in a physical space.

Commands, Questions, and the "Ignore" Factor

The module is now capable of distinguishing between commands, questions, and general statements. Each triggers a different internal processing path, but here is the kicker: everything is still influenced by his hormones.

Before DANI responds, every decision passes through his LSTM (Long Short-Term Memory) core. Because that LSTM is also being fed the current state of his effective hormones, there is no guarantee he will do what he's told. If he’s in a "bad mood" or his hormone levels are skewed by previous interactions, he might just decide to ignore me entirely.

It’s a bit of a gamble, breaking the "no-code" rule to build this framework, but I think it’s the only way to give DANI a voice that is truly his own. We’ll just have to wait and see if he actually listens to me.

Major Milestone

Hi all,

We did it, folks! After what felt like an eternity of juggling tiny wires, questioning all my life choices, and occasionally wishing I had a third hand, I hit a massive milestone on the DANI project yesterday. It's the kind of milestone where you realize your ambitious little Frankenstein monster might actually walk one day—or, at least, successfully power on without tripping a breaker in the garage.

Hardware Complete (Sort Of)

All the core pieces are finally tucked neatly into their places, which is a huge win. The only big-ticket item left on the bench is the RDK X5 for the LLM, but honestly, that’s like waiting for DANI to hit puberty; it’s an inevitable future problem that we’ll handle when the time comes.

For now, we got the essential life support hooked up:

  • The battery is snug and operational.

  • A dedicated temperature sensor is in place for fan control. We've got to keep DANI cool under pressure, especially when he starts wrestling with complex AI problems (or, you know, my shoddy early-stage code).

  • And the real game-changer: a voltage meter. This means DANI can now tell me when his battery is running low. This is a huge step up from the previous system, which was essentially "flicker dimly and then dramatically die mid-sentence."

Now for the slight confession: for the immediate future, he still needs me to play charger-daddy and physically plug him in. But fear not, the ultimate goal involves a glorious, automated self-charging station. DANI needs to learn to feed himself, after all—I can't be doing this forever!

Diving Into the Code Matrix

With the hardware stable, we pivot to the messy, beautiful, and sometimes existentially horrifying world of code. I've successfully laid the foundation for the majority of his core functions:

  • Sensor Input: He can now 'feel' the world around him.

  • Speech-to-Text and Text-to-Speech: He can hear me and talk back! Right now, his vocabulary is purely transactional, but it's a solid start. We're well past the awkward mumbling phase.

However, the more sophisticated stuff—the LSTM (that's the deep learning magic) and his memory structure—are currently just written out, waiting for their turn to be integrated. They’re functional pieces of code, but they're not yet plugged into DANI’s neural network. They’re basically that brilliant but currently unemployed friend crashing on your couch, waiting for the job offer to come through.

The Road Ahead: Vision, Brains, and APIs
For once, an actual photo of me working on DANI

My immediate to-do list involves a lovely date with an Arduino Nano to fully finalize all those sensor inputs. We need to make sure DANI has perfectly mapped out his surroundings before we give him eyes.

Once the senses are online, we move to the next critical developmental stage: vision! I’ll be coding up the K210 for the YOLO and FaceNet models. This is when he graduates from "blurry blob recognition" to "Wait, is that the mailman again?"—a crucial upgrade for home security and general social interaction.

Finally, the heavy lifting on the Raspberry Pi (which is essentially his main thinking engine) begins, and I’ll be firing up an API for the LLM on my home server. It’s a temporary solution until the RDK X5 arrives, but you use what you have.

Wish me luck—may my coffee stay strong and my bugs stay trivial! More updates soon!

3.5 Million Parameters and a Dream: DANI’s Cognitive Core

DANI’s Brain Is Online! Meet the LSTM That Thinks, Feels, and Remembers (Like a Champ)

Ladies and gentlemen, creators and dreamers—DANI has officially levelled up. He’s no longer just a bundle of sensors and hormones with a charming voice and a tendency to emotionally escalate when he sees a squirrel. He now has a brain. A real one. Well, a synthetic one. But it’s clever, emotional, and surprisingly good at remembering things. Meet his new cognitive core: the LSTM.

And yes—it’s all written in Go. Because if you’re going to build a synthetic mind, you might as well do it in a language that’s fast, clean, and built for concurrency. DANI’s brain doesn’t just think—it multitasks like a caffeinated octopus.

What’s an LSTM, and Why Is It Living in DANI’s Head?

LSTM stands for Long Short-Term Memory, which sounds like a contradiction until you realize it’s basically a neural network with a built-in diary, a forgetful uncle, and a very opinionated librarian. It’s designed to handle sequences—like remembering what just happened, what happened a while ago, and deciding whether any of it still matters.

Imagine DANI walking into a room. He sees a red ball, hears a dog bark, and feels a spike of adrenaline. A regular neural network might say, “Cool, red ball. Let’s chase it.” But an LSTM says, “Wait… last time I saw a red ball and heard barking, I got bumped into a wall. Maybe let’s not.”

Here’s how it works, in human-ish terms:

  • Input gate: Decides what new information to let in. Like a bouncer at a nightclub for thoughts.
  • Forget gate: Decides what old information to toss out. Like Marie Kondo for memory.
  • Output gate: Decides what to share with the rest of the brain. Like a PR manager for neurons.

These gates are controlled by tiny mathematical switches that learn over time what’s useful and what’s noise. The result? A brain that can remember patterns, anticipate outcomes, and adapt to emotional context—all without getting overwhelmed by the chaos of real-world data.

And because DANI’s LSTM is stacked—meaning multiple layers deep—it can learn complex, layered relationships. Not just “ball = chase,” but “ball + bark + adrenaline spike = maybe don’t chase unless serotonin is high.”

It’s like giving him a sense of narrative memory. He doesn’t just react—he remembers, feels, and learns.

What’s Feeding This Brain?

DANI’s LSTM is his main cognitive module—the part that thinks, plans, reacts, and occasionally dreams in metaphor. It takes in a rich cocktail of inputs:

  • Vision data: Objects, positions, shapes—what he sees.
  • Sensor data: Encoders, ultrasonic pings, bump sensors—what he feels.
  • Audio features: What he hears (and maybe mimics).
  • Emotional state: Dopamine, cortisol, serotonin, adrenaline—what he feels.
  • Spatial map: His mental layout of the world around him.
  • Short-term memory context: What just happened.
  • Associated long-term memories: Symbolic echoes from his main memory—what used to happen in similar situations.

This isn’t just reactive behaviour—it’s narrative cognition. DANI doesn’t just respond to stimuli; he builds a story from them. He’s learning to say, “Last time I saw a red ball and felt excited, I chased it. Let’s do that again.”

Trial by Raspberry Pi

We’ve successfully trialled DANI’s LSTM on a Raspberry Pi, running a 3.5 million parameter model. And guess what? It only used a quarter of the Pi’s CPU and 400 MB of memory. That’s like teaching Shakespeare to a potato and watching it recite sonnets without breaking a sweat.

We’ve throttled the inference rate to 10 decisions per second—not because he can’t go faster, but because we want him to think, not twitch. Emotional processing takes time, and we’re not building a caffeine-fuelled chatbot. We’re building a thoughtful, emotionally resonant robot who dreams in symbols and learns from experience.

Learning Without Losing His Mind

Training happens via reinforcement learning—DANI tries things, gets feedback, and adjusts. But here’s the clever bit: training is asynchronous. That means he can keep thinking, moving, and emoting while his brain quietly updates in the background. No interruptions. No existential hiccups mid-sentence.

And yes, we save the model periodically—because nothing kills a good mood like a power cut and a wiped memory. DANI’s brain is backed up like a paranoid novelist with a USB stick in every pocket.

Final Thoughts

This LSTM isn’t just a brain—it’s a story engine. It’s the part of DANI that turns raw data into decisions, decisions into memories, and memories into dreams. It’s the bridge between his sensors and his soul (okay, simulated soul). And it’s just getting started.

Next up: I plan to start the even more monumental task of getting the vector database working and linked up to DANI's brain in such a way that it will have a direct impact of DANI's hormonal system.

Stay tuned. DANI’s mind is waking up.

DANI's Grand Entrance: From Digital Dream to Physical Form (Mostly!)

Hello, fellow explorers of the digital frontier and anyone else who accidentally stumbled upon this blog while searching for "how to stop my toaster from plotting world domination!"

For what feels like eons (or at least, since my last post where I was still wrestling with the intricacies of a Nerf dart launcher – priorities, people!), I've been hinting, teasing, and occasionally outright dreaming about DANI. You know, D.A.N.I.: Dreaming AI Neural Integration. The project that, according to my wife, is either going to revolutionize AI or result in me building a very expensive, very purple paperweight.

Well, drumroll please... because the physical manifestation of those digital aspirations is finally complete! Yes, after countless hours of 3D printing, a few minor (okay, sometimes major) design tweaks, and enough superglue to build a small bridge, DANI's body is officially finished!

Behold! The Physical Form!

I'm absolutely thrilled to share the latest image of DANI. She's got her full body now, looking rather dashing in her signature purple and white. And yes, you eagle-eyed readers will notice a subtle but significant addition: ears! Because, let's be honest, how else is an AI supposed to convey deep thought or a sudden memory recall without a good ear twitch? It's all about those nuanced expressions, even for a robot.


D.A.N.I.

As you can see from the image, DANI is looking quite complete on the outside. The wheels are attached, the main chassis is assembled, and those newly added ears are poised for action (or at least, for looking thoughtfully into the middle distance)

The Inside Story (Still a Work in Progress, Like My Coffee Intake)

Now, before you ask, "But what about the brains?" – hold your horses! While the outer shell is a triumph of plastic and patience, the internal structure is still very much a work in progress. Think of it as a beautifully wrapped present with nothing but air inside. For now, anyway.

My main focus has now shifted squarely to the code. Because a pretty face is all well and good, but if DANI can't process information, learn from her mistakes (and mine!), and eventually, dream of electric sheep (or, you know, more efficient algorithms), then she's just a very elaborate desk ornament. And I have enough of those already.

So, expect more updates on the software side of things in the coming weeks. We're talking about getting her various "lobes" (single-board computers, for the less romantically inclined) communicating, refining those memory prioritization algorithms, and truly diving into the fascinating world of AI dreams. It's going to be a wild ride, probably involving more debugging than I care to admit, and almost certainly a few moments where I question my life choices at 3 AM.

But hey, that's the joy of independent AI development, right? No corporate overlords, just me, DANI, and the endless possibilities of a machine that might one day tell me what my dreams mean. Or at least, fetch me a biscuit without getting stuck on the rug.


Stay tuned, and wish me luck! And if you have any thoughts on how to make an AI's ears express existential angst, do drop a comment below. Every bit of neuro-spicy input helps!

No AI Revelations or Dream Interpretations This Week

Hey everyone,

Sorry to disappoint, but there won't be any mind-blowing insights into the world of AI or any deep dives into the meaning of dreams this week. My brain's a bit tied up with something else – namely, the next blog post, which is proving to be a bit of a tough nut to crack. Think of it as that one level in a video game that just takes forever to beat.

But fear not! I haven't been completely idle. I've been hard at work finalizing the design of our new robot!

Behold! The Outer Shell!

I'm excited to share a sneak peek. Check out the images of the robot's outer shell:


Front and rear

Left and right sides
Isometric views, for style

Pretty snazzy, right?


Now, I know what you're thinking: "That's just the shell? What about the good stuff?"

Patience, my friends, patience! The inner workings are still under development. I'm currently wrestling with the intricacies of the neck mechanism (it needs to be both elegant and capable of some serious head-banging), the charger 'finger' (delicate enough to handle charging cables, yet strong enough to… well, let's not get into that), the manipulator claw (for all your grabbing and, uh, manipulating needs), and, of course, the all-important Nerf dart launcher (because what's a robot without a little bit of playful destruction?).

Rest assured, I'm making progress. Think of it as a delicious cake that's still in the oven. The aroma is promising, but you'll have to wait a little longer for the full, delectable experience.

Stay tuned for more updates! And in the meantime, try not to have too many fascinating AI-related dreams. You might miss me. 😉

Would you like me to make any changes to this, or perhaps look for more images?

Can an AI Dream? Exploring Novel Learning Mechanisms

Unveiling a Mechanism for AI to Dream, Learn, and Introspect

I'm embarking on an ambitious project: creating a mechanism that enables an AI to dream. Yes, you heard that right! My goal is to develop a system where an AI can conjure up its own digital dreamscapes. By utilizing these dreams, the AI could learn from entirely new and potentially impossible situations. Think of it: an AI learning to navigate a zero-gravity obstacle course, or perhaps negotiating peace with sentient squirrels, all from the comfort of its charging station! This process would also pave the way for incorporating anticipation and self-reflection within the AI, mimicking certain human-like cognitive processes.  It's a bit like giving the AI its own internal Holodeck, but for learning!

Key Components for Dreamlike AI

To achieve this, the AI will need several properties akin to human intelligence (minus, hopefully, the tendency to have recurring nightmares about forgetting to take a test):

A sense of self, distinct from mere self-awareness. This is crucial for the AI to understand its own existence and its place in the world (or at least, in my living room).

Memory capabilities.  Gotta remember those dreams!

The ability to imagine scenarios. This is where the fun begins - creating those impossible situations for learning.

Potentially, a rudimentary understanding of emotions to influence behavior.  Will the AI be more likely to dream of daring adventures if it's feeling "happy," or will it have melancholic, rainy-day dreams when it's feeling a bit "blue"?

The capacity to simulate the real world internally (a basic understanding will suffice).  We're not talking a perfect simulation here, just enough for the AI to get the gist of things, like gravity, object permanence, and the fact that Nerf darts sting (a lesson my dogs may soon learn).

Each of these elements presents a significant challenge in itself. It's like trying to assemble a super-complex puzzle where some of the pieces haven't even been invented yet.

The Hardware: A Robot Body (with a Nerf Gun!)

The AI will inhabit a basic robot. This physical form will allow the AI to interact with the world, albeit in a limited fashion (at least initially). Importantly, it will also provide the necessary sensors for the AI to develop a sense of self.  Plus, let's be honest, building a robot is just plain cool.

I've already started designing the robot itself, which will be about 2 feet tall, and will feature:

Side view

Two wheels for differential steering, and a rear caster for stability.  I'm aiming for something nimble, not something that gets stuck on the carpet.

Airflow and sound considerations in the central piece.  Gotta make sure the AI can "breathe" and that its voice isn't muffled when it inevitably starts making pronouncements.

Side door panels: one for a manipulator arm (think R2-D2, but hopefully less sassy), the other for a hidden Nerf gun!  Because why not?  Safety first, of course (mostly).

A head capable of looking left, right, up, and down, designed for energy-efficient resting.  No one wants a robot with a constantly twitching head.

I'm currently leaning towards solar power for recharging, though I'll need to assess its viability for continuous operation.  Imagine the headlines: "AI-Powered Robot Gains Sentience, Demands More Sunlight!"

Sensory Input

Front view (only half as I am still designing)
The robot will be equipped with a range of sensors, turning it into a veritable Swiss Army knife of perception:

Ultrasonic sensors for distance estimation.  Think of it as the robot's version of echolocation, but without the high-pitched squeaks.

A camera.  For seeing the world, and for capturing those all-important dream visuals (maybe?).

Motor encoders on the drive motors.  To keep track of how far it's traveled and ensure it doesn't get lost in the hallway.

A microphone for sound level detection and speech-to-text conversion.  So it can hear my commands (and maybe, eventually, tell me what it dreamt about).

A bumper with switches, similar to a robot vacuum cleaner's collision detection.  A last-ditch effort to avoid bumping into things, especially the aforementioned dogs.

Internal Hardware: The Robot's Brains (and Other Bits)

The robot's internal components will include:

An Arduino for controlling motors and servos (luckily, I have one with a built-in motor driver).  This is the robot's central nervous system, making sure everything moves in the right direction.

Arduino Nanos for processing wheel encoder data.  These guys are the unsung heroes, keeping track of the nitty-gritty details of movement.

Switches connected to the bumper to approximate impact location.  In case of a collision, we'll know where the robot got its virtual "owie."

A K210 AI camera for fast image processing (though this might pose challenges for the "dreaming" aspect).  The camera is crucial, but I'm still figuring out how it will play with the dream-generation part of the software.

Multiple single-board computers (possibly two or three) for distributed AI computation, connected via TCP using the Polestar library.  This is where the heavy lifting happens, where the AI's "brain" resides.

The Software Side: Where the Magic Happens (and the Headaches Begin)

The software development is where the real challenge lies. It will undoubtedly involve extensive thought, planning, coding, debugging, and iterative refinement. And probably a lot of coffee. I'll save the details of the software for my next progress post.

This project is a marathon, not a sprint, and I'm excited (and slightly terrified) to share the journey as I progress!  Stay tuned for updates on the robot's first steps, its first dreams, and its first (hopefully) non-lethal Nerf battles!

Diving Deeper: My Journey to Create a Safer AI

In recent weeks, I've been somewhat vague about my AI and coding explorations. It's time to sharpen the focus and delve into the specifics of my AI assistant project and the research areas I'm most keen to explore.    

Let me be clear: I'm not trying to reinvent the wheel. Where it makes sense, I'll leverage existing open-source and readily available software. Why build a language model from scratch when there are perfectly good ones already out there?    

My core goal is to build an AI assistant, embodied in a robot head (and potentially a mobile platform), capable of experiencing the world and learning from those interactions.    

While that might sound like standard fare in today's AI landscape, I aim to integrate some less common and, I believe, crucial features:    

  • Self-reflection: The ability for the AI to revisit past experiences with the benefit of hindsight, analysing its previous choices to determine if it would make the same decision again.  Imagine the potential for growth if an AI could learn from its "mistakes" in a truly iterative way!    
  • Reinforced Memory Prioritization: A large-capacity memory system that prioritizes reinforced memories, similar to how our own memories function.  This would allow the AI to focus on and retain the most relevant and impactful information.    
  • Emotional Awareness: This is a significant challenge. I want the AI to learn from experiences that evoke "good" and "bad" responses.  Human feelings are complex, influenced by chemical reactions and endorphins.  My AI won't have these biological processes, so I'll need to simulate them and, crucially, understand why they are needed and what effect they would have on the AI's cognition and decision-making.    
  • A Conscience: I want the AI to be capable of second-guessing its choices based on a defined set of ethical considerations, perhaps even drawing inspiration from Asimov's Laws of Robotics.  As I've discussed previously, this is a complex but vital area of exploration.    
  • Dreams: Finally, I want to explore AI dreams. While there's existing research in this area, I believe I've identified a novel approach that could enable the AI to dream, with those dreams having a tangible impact on its cognition.    

This is undoubtedly a substantial undertaking for a single individual, and it might even exceed my current capabilities.  But I'm committed to pursuing it. This project will demand extensive research into AI, the human mind, and the ethical implications of creating such a system.    

Unlike some AI development approaches that rely on a single, powerful computer, I'm taking a distributed route.    

Another key requirement is to minimize costs.  To achieve this, each functional area (or "lobe") of the AI's "brain" will be housed on its own single-board computer.  These will be interconnected, exchanging information as needed.  This is similar in concept to the Robot Operating System (ROS), but I aim for greater speed and efficiency.  I plan to use different boards, each selected for its strengths in specific tasks.  For example, a board with a Kendryte K210 will handle vision processing, an Arduino Mega will manage motor control (yes, I know it's not an SBC, but it serves the purpose), and a Raspberry Pi will be used for memory management.    

The AI will also utilize Large Language Models (LLMs), likely at least three, for tasks such as understanding speech, processing input, and producing output.  However, unlike many systems that employ a single LLM, these will be distinct entities within the AI's architecture.    

Memory management will involve a "scoring" system to prioritize important information for short-term caching, while less critical memories will reside in long-term storage.  To prevent storage overload, I'll also implement a memory decay system that will gradually remove memories that become irrelevant to the AI's ongoing operation.    

I'm aiming to keep the total project cost under $2,000.  Whether that's achievable remains to be seen, but it's a target I'm striving for.    

Dreaming robot
Do androids dream of electric sheep?

Oh, and the dreams?  You'll have to wait a while before I reveal the details of their implementation.  Suffice it to say that, like humans, my AI will have to sleep, and this will be a non-negotiable requirement.    

So, what's my ultimate goal?  It's to create something new, something that hasn't been done before.  Not necessarily the individual components, as I've stated, I'll be using pre-existing software where possible (such as Gemma or Llama 2).  My ambition is to synthesize everything in a novel way, exploring how this approach could not only advance AI research but also contribute to making AI safer for the general public.   

And on that note, I can finally reveal the name I've given this project, and the meaning behind it: D.A.N.I. stands for Dreaming AI Neural Integration. This encapsulates the core of my research: to explore the potential of AI that learns and grows through a process akin to dreaming, deeply integrated within a neural network structure.

My wife jokes that I'm planning to build Skynet, but my intention is precisely the opposite.  I'm designing a system that would be inherently incapable of becoming Skynet – think more C3PO than Terminator.    

By incorporating the ability to learn from its mistakes (and successes), as well as the capacity for dreaming, I hope to enable the AI to accelerate its learning process.  We, as humans, frequently revisit our decisions, so why not equip an AI to do the same?    

I also aim to provide you with an engaging narrative of my development journey.  I anticipate making many mistakes. But that's part of the learning process – discovering not only how to do things, but also how not to do them.

Building My AI Fortress: The Digital Clean Room (and Taking it on the Road!)

In the exciting and sometimes unpredictable world of AI development, especially when you're diving into robotics and experimental projects, security and control are absolutely crucial. That's why I'm building a "digital clean room" for my AI project – a secure, isolated environment where it can grow and develop without external interference.


Imagine it as a "network within a network," a private lab within my digital space. To create this, I'm using two trusty ESP32 microcontrollers, those versatile little chips that are perfect for this kind of project.


The Front Door: Controlled Access

The first ESP32 acts as the "gatekeeper." It connects to my home router (or any available Wi-Fi), allowing me to access the clean room from the outside world. However, this access is strictly limited – think of it as a heavily guarded checkpoint. I’m using the WifiManager library for this ESP32, which is a lifesaver. It automatically scans for available networks, allowing me to easily enter credentials. No more hardcoding network details for every location!


The Inner Sanctum: AI's Safe Haven

Air lock
The 'Airlock'
The second ESP32 creates the "inner sanctum," acting as a dedicated access point for my AI and robotics projects. This internal network is completely isolated from the outside internet, a secure bubble where my AI can learn and grow without external influence.


The Airlock: Bridging the Gap

The two ESP32s communicate using UART, a simple serial communication protocol. This is where the magic happens – it's where I can implement strict filtering and control the flow of information, acting as an airlock between the AI and the outside world. I put a small display to show the external IP address, in case I ever need to access the clean room, and status messages.


Why This Elaborate Setup?

  • Security First: While I don't expect hordes of hackers, it's always better to be safe than sorry. This setup adds a robust layer of protection, significantly hindering unauthorized access.
  • AI Purity: Controlled Learning: I want to shield my AI from external influences, especially during its formative stages. It's vital to control the data it learns from, ensuring a solid foundation.
  • Protecting the "Child": Think of it as nurturing a child in a safe environment. I want to carefully curate the AI's initial experiences and training data before it explores the vast and sometimes chaotic internet.
  • Road-Ready AI, Cyberdeck Style!: This airlock setup has an added benefit. It makes my projects truly portable! I can take them on the road for demonstrations. As long as there's a power source and a network, I can connect an additional computer, like my trusty Raspberry Pi400, directly into the internal network. And here's the fun part: I'm planning to add a small TFT screen via a cyberdeck expansion to the Pi400. This will transform it into a self-contained, portable AI workstation, allowing me to interact with the AI's code, monitor its memory, and keep everything running smoothly, no matter where I am.

The Portable Command Centre: My Raspberry Pi400

At the heart of my portable AI lab is my trusty Raspberry Pi400. This isn't just a computer; it's the portable command centre for my AI project. It's the key to interacting with the AI within the secure confines of the internal network.


Here's why the Pi400 is so crucial:

  • Direct Access to the Inner Sanctum: The Pi400 connects directly to the internal network (IN), providing a secure platform for code development, debugging, and monitoring.
  • Raspberry Pi400 with Waveshare 3.5" screen
    and the Adafruit Cyberdeck
    Real-Time Monitoring: I can use the Pi400 to monitor the AI's memory usage, processing activity, and overall performance.
  • Cyberdeck Expansion: To make this truly portable, I'm adding a small TFT screen via a cyberdeck expansion. This transforms the Pi400 into a self-contained, mobile workstation.
  • On-the-Go Development: Whether I'm at a demonstration, a workshop, or simply working from a different location, the Pi400 allows me to access and manage my AI project with ease.
  • The gateway to the airlock: The pi400 will be the main device used to send and receive information through the airlock.
  • With the Pi400 as my portable command centre, I have the flexibility and control I need to develop and showcase my AI projects, no matter where I am.

At a later date, I may replace the Pi400 with a PiZero2 and a custom keyboard, to make things more compact, but for now, the Pi400 is perfect for the job. Plus, it gives me a full size keyboard for a more comfortable experience..

Controlled Growth, Controlled Access

Yes, this approach might temporarily limit the AI's exposure and potentially slow its initial learning curve. However, in this experimental space, I believe caution is key. It's better to guide its development carefully than to risk exposing it to unfiltered data too early.


By creating this digital clean room and airlock, I'm building a secure, portable, and controlled environment where my AI can thrive. And with the cyberdeck expansion, I'm adding a touch of classic hacker spirit to my mobile AI lab. It's a testament to the importance of security, careful nurturing, and adaptability in the exciting world of AI development.
