Gonna do some new #introductions via various stuff I’ve work on over the next few days to help find my scene!

My first serious personal project was about 10 years ago when I wrote this video codec for the Apple II, which played short looping animations converted from animated gifs. You load em off of a standard 5.25” 140k floppy!

Here’s the hackaday on it:

Animated GIFs On An Apple II

Before the Internet, computer enthusiasts needed to get their cat pictures, image macros, and animated gifs somehow. If only [Nate] was writing code back in the 80s: he created a video player for t…

More #introduction content!
I’m also somewhat known porting a C. elegans nervous system model (connectome) to the Arduino Uno, so it could be used in very low cost or resource constrained platforms.
Yes, this is a robot that thinks it’s a worm, lol

Nematoduino: A Roundworm Neural Model On An Arduino

When it comes to building a neural network to simulate complex behavior, Arduino isn’t exactly the first platform that springs to mind. But when your goal is to model the behavior of an organ…

#introduction content continued! as a follow on to nematoduino, I made nematode.farm, which is a (very) simple browser based game where the “opponent” is many instances of the emulated C. elegans nematode. I think this may be the first game ever where enemy AI is based on an emulated organism.
written in C, SDL2, and compiled in webassembly 
can play here (need arrow keys)

Next in my #introduction posts featuring Stuff I’ve Made:

This is the Chernobyl Dice: a Cold War era themed quantum RNG. It uses the clicks of a Geiger counter nestled next to an array of uranium glass marbles to generate random bits displayed on Nixie tubes.

This is a *disgustingly fair* dice and I’ve run the tests to prove it, lol

Roll The Bones Chernobyl Style

We’re suckers for the Fallout aesthetic, so anything with a post-apocalyptic vibe is sure to get our attention. With a mid-century look, Nixie tubes, a brushed metal faceplate, and just a tou…

@ComradeRobot "After some adjustment for the bias toward zeroes due to the relative rarity of decay events" why not use the approach of "measure the time difference between three decay events, '0' if first longer than second, '1' otherwise"?

@numist that would work! (at least in theory—real sensors have all sorts of unexpected bias). unclear to me right now whether or not your suggested algorithm would generate “one bit for click”—it obviously could if you just roll it forward but id be slightly concerned by the time correlation that would persist (again, real world microcontrollers and sensors)

@ComradeRobot You'd need two clicks per bit, but it would be bias-free with no corrections needed.

@numist yeah this thing already takes a few seconds to make a single byte haha. also im not sure id trust the microcontroller clock to be bias free or stable. with more radiation and a seriously stable clock that would probably be the way to go though
