I’ve already gotten a pile of tips on Guitar Hero controllers today, so here we go. The first one is already making the rounds. [Mark] replaced strummer with a touchscreen LCD and a magnetic switch. [Mark]s ultimate goal is to add some optical sensing and make the guitar self playing. For details, hit the acidmods thread or just watch the proof of concept demo.
[Johan] sent in the second controller of the day, and it’s probably my favorite for guitar bling. The original mushy switches were replaced with micro-switches and CNC milled replacement buttons. Each button is individually lit with LEDs and a cold cathode lights up translucent panel in the body. A PIC controller controls the lights and provides some input options for button tapping. The video is actually pretty entertaining to watch.
For a little bonus, check out [Mastershake916]‘s cast Hack-A-Day pendant.
