This project originally was meant as a fathers day gift for my tetris-loving father, and I felt like it should be available for others if they want to make a pretty small tetris clone. This was the smallest I could make it with a big enough battery and a thick durable 3d printed housing.
Everything is also through hole soldering, so anyone with even just basic knowledge of soldering could make this.
I've posted the schematics + 3d printable files below, but its best to view the most up to date ones from my github page for the project here: https://github.com/dombeef/pockeTETRIS
Love this project and excited to build it! I have all the components and ready to assemble but wondering about in-circuit programming. I see the pins labeled 10-13 and the comment below to power the AT85 using the Arduino. It's not clear to me how to connect external power to the AT85 for programming once soldered into the PCB. I didn't see a photo of the PCB with the AT85 soldered in but I assume it is direct soldered (not in a socket) .
