CPU 4 Background. Weird CPU My first CPU (https://hackaday.io/project/12879-weird-cpu) was an 8 bit TTA (Transport Triggered Architecture). It has a front panel and sits happily on my shelf chasing LEDs in circles (such is the life of a simple CPU):...
TD4 CPU Here is a schematic from the Internet: (source: http://kamakurium.com/wp-content/uploads/2016/01/cpu_td4.jpg) The entire CPU has only 12 TTL chips. Yes it has a switch based ROM! The schematic also shows the 12 OpCodes. It is not perfect,...
The InceptionThe theme for DEF CON 25 this year was retro-tech, and for several months I've had the idea to make some kind of retro badge. I wanted to do it just for fun, and as a conversation starter, at which it was a great success!This badge was made...

This project is gradually improving. It is fully functional at this point, our kids use it already every day. Nevertheless, we have planned several improvement for the second release, such as a night light mode. Features 3D printed case covered with...
The MicroVIP is built with an inexpensive Altera Cyclone II FPGA module that I got on e-bay. The computer board is built with point-to-point wiring. The current features of the MicroVIP are: CDP1802 Microprocessor and CDP1861...
Firmata is a protocol that is used to communicate with microcontrollers from any tablet/pc over the serial interface. There are implementations of Firmata for another platform too along with Arduino. You can find support for Firmata if you are using any...
Guiding Design Goals and Philosophy for Lock in Amplifier: Similar capabilities to the sr530. This is a common, workhorse instrument that I would love to have on my bench. The big features i’m going for are: Expense: this should be “affordable”....
