The means to rapidly test out an thought, and then expand and acquire it, is what immediate prototyping is all about. Although we have a tendency to feel of 3D printing when speedy prototyping is described, [Brick Technology] reminds us of the energy of Lego, as he rapidly builds and improves an electromechanical drum equipment.

Employing Lego Technic pieces, he starts off with a very simple new music box-design and style drum with moveable pins that pluck on spring-loaded levers, which in switch hit piezoelectric discs. The electronics aspect is basic, with the discs wired to a Roland seem module from an present digital drum kit. With the ability to right away adjust, incorporate and take out pieces, he promptly finds and fixes the trouble of acquiring eleven hammer mechanisms collectively and operating smoothly.

To get all around the constrained pin area on the drum and increase the duration and variation prospective of the rhythms, [Brick Technology] moved to a belt design and style that can accommodate noticeably much more pins. He also included an electric motor and many gearbox ratios for reliable and adjustable tempo. Jointly with his water vortex ball machine, he helps make us imagine our workshops probably require a handful of hundred Lego Technic items.

To incorporate to the record of excuses to get more Lego, we’ve also found the plastic blocks get utilised for every thing from RC submarines to response wheels and even info storage.
