After using an AVRISP MKII created from an Arduino Uno for years, I decided to finally figure out where that custom firmware came from. Turns out it came from [LUFA](https://github.com/abcminiuser/lufa/tree/master/Projects/AVRISP-MKII). With that, I designed a board around it. I definitely didn’t want to buy new parts for this, so I used what I had. While the MPLAB Snap is preferred due to its wide protocol support, I will continue using the AVRISP MKII since it’s supported in Arduino IDE. After modifying the LUFA project a bit to match the clock speed, GPIO, and chip, I got it working! All of my programmers are now tiny and it’s beautiful.
