A while ago I sold a Rx Punk on ebay. When I went to ship it, I noticed the name was Adam Horovitz, which rung a bell as he is in the Beastie Boys.
I asked him if he was adrock… He said “yes, can you turn this football game into a drum machine?”

I wasn’t going to say no. so i said yes. I had the idea to take the guts from one of those cool circle shaped lo-fi drum toys (i happened to have one half torn apart in the attic).
Both have 5 buttons, so that was a nice start. Unfortunately the old buttons on the football game were unreliable and hard to mesh with the drum toy circuit. I had to build a small bank of buttons and then fit them behind the original ones. All in all it was a lot of shaping the elements to fit together inside the football game, rather than comlicated circuit work.
Added a 1/8″ line out, and an extreme pitch knob that tends to glitch at either end of the spectrum. The body contact adds a sizzly sound…delicious. The run switch powers the unit on.
