Motor power lead filter 1.
This was my first attempt at constructing a crude L-C filter to cut down on the RF noise coming from the Cyclone motor controller that was interfering with the PowerTap computer. (The "L" are the ferrite beads. The cap is a 1000uF in parallel with a 0.01uF ceramic.) This helped cut down on RF noise at the lowest power levels, but I still had interference at reasonable power levels.
