Written by John Yan on 4/2/2021 for PC If you missed the first two articles in my journey in modding the Atari Ultimate Dual Fight Stick with Trackball, you can catch the part where I added an internal battery bank and power switch here and the other mod was adding in external USB ports as well as an HDMI port here. Today, I’m going to replace the buttons with LED buttons and also put a nice little LED light to let me know if the Raspberry Pi is still drawing power. Let me start by saying the buttons included in the stick feel really good and are responsive. They worked well in my testing of the Fight Stick, but I wanted to add a little flare to the setup.
