bullet sensor

thingiverse

I built upon ammomike's concept, demonstrating how to connect a sensor to his speed controller. I added an adjustable sensor holder that people are now printing onto their drop tube feeders. This allows you to slide your drop tube through the sensor holder, giving you control over distance and bullet capacity without being tied down by a fixed sensor attachment. To make it more affordable, I found a compact sensor at a lower price point and provided the wiring instructions. The sensor has potential for use in other projects beyond this one. Note: Before working with electricity, consult a licensed electrical technician to ensure your safety.
