We featured Nikodem’s bike tachometer last September on this blog. He’s now sharing with us another DIY project called DIY Arduino controlled Egg-Bot. It’s a DIY version of the original Egg-bot created by Evil Mad Scientist Laboratories.

You can follow the step-by-step tutorial on Instructables and here’s a preview of the bill of materials you’ll need to make the project at home:

– Stepper motor with 200 steps per revolution (x2)  / I use 12V and 0,33A but you can use other.
– Stepper motor driver A4988 (x2)
– Arduino Uno
– Power supply for stepper
– Micro servo
– Plastic plate, wood
– 40cm screws x3 and 12 nuts for it’s
– Two Lego wheels
– Markers in different colors
– Drill, knife, saw, screwdriver, double sided tape, wood glue, wire, soldering iron, rubber bands
– Everything you need to make PCB
