I certainly did. I made myself my own computing device. With a soldering iron and a pair of pliers, basically. I would say it's a computer, but then, about 80 % people would not get what it means to make a computer, as opposed to building one
Love how you've etched the game characters into the board. I used to do the same thing when I was on my electronic course but unfortunately the tutor didn't like my creativeness and had me thrown from the course altogether. Some people just don't appreciate true art
in reply to your questions, it is meant to be a simple 8-bit computer, roughly equivalent in functionality to a Sinclair ZX Spectrum (TV output, keyboard, etc.) It is not a clone, just somewhat similar. The CPU is an Atmel AVR, instead of a Z80. I wrote more details about the hardware design my latest blog post.
