And Just Like That, We Have A CPU!

A project log for The Spikeputor

I am building a computer featuring a 16-bit RISC CPU made of discrete transistors for learning, fun and art. It will be pretty large.

🚨Phase One of the Spikeputor Project has been completed! 🚨

Integrating all of the modules was just a matter of making cables to connect everything, and writing some Arduino code to load data into the Spikeputor's memory through the DMA model. Here's a video describing the maiden voyage:

Many more things to do, including a bunch of clean-up, making some memory from discrete transistors, adding some more I/O features, and optimizing the top speed.

But for now, I'm just happy the thing actually works!

Very impressive, congratulations. Truly (LSD) Large Scale Disintegration. Now I know what kind of hacker buys those 500 count boxes of LEDs from suppliers. 😁
