DIY home made 555 drum machine from an electronic drumstick - in progress

This is a drum machine that I am making. The core is from an old electronic drumstick that I found at a thrift store. It is opperated by swinging it just like a real drum stick and stopping it in mid air. When the electronic drumstick stops, it makes a sound.

The default sound is a snare but there are also two more sounds. If you hold one button and swing the electronic drum stick it makes a bass drum sound. The other button has a crash symbol.

The drum machine is being timed by a 555 timer and a 4017 decade counter. It will have a 3-way switch for every step in from the 4017. One for each sound. In addition, it will have an on/off switch and (if all goes well) a pitch adjustment for every step.

will you post the schematic somewhere?[;

[redepoch76]

@athask8 well... I think I still have the schematic... I will post it if I do... if not...

it's pretty simple... i just took the drum stick apart... found the trigger... hooked the output of the 555 up to that... and another from the output of the 4017 to a three way swithch... up is symbol, down is bass drum, and center and when the switch is off (center) then that is the snare drum... the output from the 4017 decade counter is what is choosing which sound is played.
