  • I wrote a dinky little GUI in java for this device if anyone wants to check it out. Its at my site: http://www.servophilia.com/java.html

  • Is anyone still having high pitch noise coming off of the booster coil? I didn’t think much of it until I could not get reliable analog reads from the analog pins. I discovered that the booster coil induced noise into the analog pins due to proximity. If you have a shield with a high pitch booster circuit then attach a 10mF capacitor across the 5v supply as close to the shield(if not soldered on)as possible to get rid of the hum.

  • If only Sparkfun had a wedding registry…

No public wish lists :(
