Silly string RC tank

An RC tank which shoots silly string. Based on a cheap tank chassis kit from Banggood, an Arduino Uno clone, a cheap Arduino motor shield clone and 3D printed parts.

This is a true multi-discipline DIY project with electronics, coding, assembly and 3D printing involved. All files are provided free of charge for you make the tank at home by following my video guides:
