Step 4Atlernate Generators
As an alternative to the bowed-stick interface, other generators can be crafted.
For example, the sliding carriage from an old printer makes a good generator because its the right width for moving left and right.
Also, you can mount wheel hubs on stepper motors and use them in creative ways. For example, try wrapping a cord around a motor shaft like this to make a bowed-string generator. It's good practice for starting fires! :)
In the oscilloscope photo below, you can see the each time the carriage slider is wiggled back and forth, kind of like strumming a guitar, it charges the internal capacitor a little bit higher. Usually you can make about 1-4 Watts or so with this kind of generator and its proportional to your movement, so small movements make quieter sounds inherently, you don't even have to program or build that into the synthesizer!
