Below are a list of external sites that have some great info on the components I use in the videos. Please note, I’ve patched together knowledge from all of these to build my creation such as:

  • Some use Arduino while I’m using Raspberry Pi
  • Some use ULN2803 while I’m using ULN2003.

Gearing References

http://www.revrobotics.com/content/docs/Gear-Guide.pdf – This is a GREAT reference if you’re not familiar with the specifics of how gears are designed, gear boxes are assembled for speed or power, and pitch, diameter, etc.
