Arduinos are great, but the exposed circuitry on the bottom could short out if accidentally touched to something conductive. We made tiny feet from balls to Sugru. Sugru is non-conductive, and it also lifts the Arduino up a little off the surface.
1-2 packets of Sugru (depending on the size foot you would like)
Step 1: Roll Sugru Into Little Balls
Roll into 4 small balls. Here we show two balls with an Arduino.
Step 2: Attach Feet to Arduino
Press the balls of Sugru onto the base of the Arduino.
Turn it right-side-up and press onto a table or hard surface to flatten the balls into feet.
Allow to harden for 24 hours.
