First run of CloverPit 💪
I'm playing with visualization of the nand-based circuits. I'm using the awesome graphviz, but sometimes they're too much for it...
... but it's really fun to make absolutely unreadable graphs!
Here's one: the flattened nand viz for a 4-Way 16-bit wide Multiplexer.
I absolutely love it <3

I finally merged a branch in my NAND experiments!
I focused on reducing the size, by bit-packing the base encoder
(Almost) all basic logic gates and adders up to 8 bits can be encoded in 78 bytes! zlib and lzma can't even compress it further.

Here's what it looks like:

This one took a bit more time: polarity detector, still using a linear hall effect sensor
You can see the first two magnets have different facing poles, and my implant, a cylinder, has one pole closer to my fingertip, and the other closer to my knuckle.
So much fun!
(Also, very good camera focus)

Next little project: dimming progressively a LED using a linear hall effect sensor!

I'm having a blast (re)learning electronics!
My left ring finger have a magnet implant for 5 years, but there's rejection, so it must go...
It's really hard, but for the swansong I want to play as much as possible with it. So, here's a LED turning on when a reed switch detects the magnet!

I've made a tiny web app with Scrappy (pontus.granstrom.me/scrappy/)! Just to count how often I sip some water. It was really easy, something like 15 or 20min! Just by looking at some examples
It's theoretically shareable and collaborative, but I just want to use it from my phone...

Here's the graph for a full-adder, meaning a circuit that can add three bits together:

Here's the graph for a full-adder, meaning a circuit that can add three bits together:
For context, it's for my personal project: encoding and decoding in the smallest number of bytes logic circuit defined only from nand gates. I wanted to have a graph of the circuits, to help debugging (it was useful in the next hour). And it's pretty and nerdy!
