Build An 8-Bit Breadboard Computer from Scratch by Ben Eater - Complete Kit (Parts 1-4)
If you're interested in following along with Ben Eater's 8-bit breadboard computer videos and building your own, we've assembled kits that include all of the components used in the videos, including the Arduino EEPROM programmer and a 5 volt power supply. It's a challenging but extremely rewarding project. Be sure to view each of the kits below for all of the informational and build videos.
I broke the whole thing into four kits if you want to take things slow. There's no right way to do this project. There are many substitutions and other approaches that will work just as well (or better), so if you want to build something similar and can't find all the parts, try to figure out what the missing part does and find a different way of doing it. It may not work the first time, but you'll learn a lot from trying to figure out why.
