I love mechanical gears and Shimano XT is one of the best examples of how to do it. Photo: Deven McCoy The cassettes are a bit more complex from an installation standpoint than SRAM's.

[Steve Mould] shows us a different take – the experimentation kit called Spintronics, which goes the mechanical way, using chains, gears, springs and to simulate the flow of current and the ...

A diode allows current to travel in only one direction. With that in mind, [Alex] built a mechanical diode that will only allow gear rotation in one direction to be transmitted through the system.
