This is the project I am working on right now.
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.
