I am a guitar player. Some of us are eager to play drums with feet only while playing guitar. At least kick, snare, hithat. There are no electronic solutions, light, transportable, no extra cables and tiny. Here are some illustrations of what could be possible :
Some ideas :
- Tapping with the sole or the heel triggers a different drum
- Using pad if needed instead of strokes sensors devices
There is an open market for you in this area.
I can test any prototype if needed.
