Latest print, this one required a video. Replacement cap for Dillon powder measure. Inside is an arduino controller, small LCD screen, a rotary encoder and a drone flight controller which measures distance. What you see in the video is normal operation. What you don't see is the menus to calibrate empty and full levels/measurements and the threshold level you want the buzzer to alert you that the powder is low. I set it at 15% arbitrarily for this video. It also guesstimates the number of grains remaining based on how much physical space has been emptied, as measured by the little flight controller in the base.
Remove your existing Dillon powder cap, replace it with this, plug it in, calibrate (which takes a few seconds) and good to go.
