Lego Plays Electronic Drums | Hackaday


The ability to rapidly check out out an plan, and then expand and produce it, is what swift prototyping is all about. Despite the fact that we tend to consider of 3D printing when fast prototyping is pointed out, [Brick Technology] reminds us of the electric power of Lego, as he promptly builds and enhances an electromechanical drum device.

Using Lego Technic items, he starts with a easy new music box-style drum with moveable pins that pluck on spring-loaded levers, which in turn strike piezoelectric discs. The electronics aspect is basic, with the discs wired to a Roland audio module from an current digital drum kit. With the ability to instantly regulate, increase and take out items, he speedily finds and fixes the issue of getting eleven hammer mechanisms alongside one another and doing work efficiently.

To get around the restricted pin space on the drum and improve the size and variation probable of the rhythms, [Brick Technology] moved to a belt style and design that can accommodate considerably additional pins. He also included an electric motor and numerous gearbox ratios for steady and adjustable tempo. With each other with his drinking water vortex ball equipment, he would make us imagine our workshops most likely require a few hundred Lego Technic pieces.

To increase to the listing of excuses to get far more Lego, we have also witnessed the plastic blocks get made use of for every little thing from RC submarines to reaction wheels and even facts storage.
