ATinyGame is a game console that fits in 1 hand, with a program smaller than 1kB, all for $1 ($1.50 now, thanks chip shortage).

Read the harrowing tale of its development: The Assembly Instruction that Saved Christmas. Take a look at the circuit diagram and printed circuit board layout on the OSHWLab project. See the assembly code (with lots of fun comments on how I golfed it down to 1kB) in this repo. Download the spreadsheet of costs for the project. Expect tutorials and videos soon! Follow me on mastodon for updates.

Info About v1

Download the v1 spreadsheet of costs for the project. You can see the v1 board design on EasyEDA (old version here). Note that there are some changes and caveats to this design. The PCB design was incorrect, which required some adjustments and extra components after the fact. The code for v1 and v2 are the same.
