p.s. Glad to know you are a specialist of robotics, Nova!
Shoot me your code. I can have a look at it if you want. Are you bit-banging the Arduino functions? Interrupts and PWM outputs are very, very nice when you get them set up. If you swapped the three Arduino Unos out for one Arduino Due you can definitely monitor current, frequency and temperature with a single board, but you could probably also generate your sine waves. Arduino Dues are very fast. There are also lots of other (and much faster) boards to choose from as well. If you're having frequency and noise issues driving it directly from a microcontroller might solve some oscillator problems.

Again, awesome project and great work.
