The Stockholm Mini Maker Faire 2014 has just finished up, and [Johnny Eriksson] was awarded the Maker of the Year award for his very impressive electromechanical one man band.
As a musician/electrician/furniture carpenter, [Johnny] has quite a few skills — and he wanted to try putting them altogether for a project. He calls it the Popmaskinen (the pop machine).
Using MIDI keyboards, buttons, and knobs, the Popmaskinen translates digital outputs to physical instruments controlled by various electromechanical components. One of our favorite parts is the guitars, which use solenoids to strum, and even more solenoids to squeeze various cords on the pair of guitars.
Perhaps one of the other most interesting parts of this build is the “taktverket” or pace-keeper. It’s a large metal cylinder with adjustable protrusions which actually trigger the individual instruments — it’s kind of like how a music box works. By playing with some of the adjustable switches he can turn individual instruments on and off, which will play music according to the taktverket’s pattern.
