“This Instructable will show you how to make a Raspberry Pi powered robotic drum machine. It really is a fun, creative, interactive project. Ill show you how to make the internal workings, but the actual drums is going to be up to you, giving you the opportunity to make something completely unique to you. For my machine I have used as many found items as I can… hammers from a piano rescued from my neighbours skip, a fishing net I found on the beach, an empty bake bean can, wooden spoons, an empty beer bottle, beer bottle tops and a desk bell among other things, but let your imagination go crazy - see what you have around the house, just about anything that makes a noise when hit can be used, and it will really make your project your own.To control it, you have 2 options:
A browser based step sequence which I have called PiBeat - This is great fun and lets you control your drum machine interactively from your Pi, or any device on the same network (such as your phone, tablet or computer). We will install it on your Pi later, but a preview can be seen here, and the code is in GitHub here. A python script to program a drum pattern. This is a great way to create a rhythm for you to jam along with on your guitar etc.I try to keep costs down and as you will see in the next step, no expensive specialist tools are required. I have also tried to explain how things work in every step, making it a great project even if you are a relative newcomer to the world of Pi’s, coding and electronics and on a limited budget.
OK, lets get to work!”
