Random audio track playing pullup bar

Post by TheOnlyJonto »

I have an idea for a custom made pullup bar that would use a force sensing strip (like this) in the grips to play a motivational audio clip while holding on to it. There would be multiple audio clips and it would randomly choose one, though the audio would only play while sensing force on one of the grips and would stop when you let go.

It would need to have an amplifier and a speaker, but as for the other components I'm not sure where to start. Can anyone point me in the right direction? I'm hoping Adafruit offers some kind of board that could accomplish what I need.

This would be a Christmas gift for my brother and I would appreciate any input on bringing it to life!

This is a cool idea.

If you have a metal pull-up bar you could measure conductivity changes by using an ADC pin and a wire to the bar. Same deal for a captouch type interface. I'm not sure that a FSR is necessary unless you cared about pressure of the grip.

The Feather M4 + Feather Music Maker would be a good compact choice for a player. That way you can measure the bar interaction and kick tracks off from the microSD card.

USB speakers would be the easiest to get decent volume and power the whole project off a USB power block or wall wart.

Excellent! This should really help me get started. I'm going to order parts and get testing. Thanks for the links!
