Powder Check Die

This is a powder check die that uses a battery, led and alarm with a reed magnet to sense the plunger atthe correct height.

I wanted a powder check that beeps and lights a red LED when the powder in the case is outside of the settings. I bought 4 PCDs for my X-10 and none fit (it has very little room). So I designed and built this one with the electrical board as a "slip in" so you can wire outside the cover box and slip it in after you get your wires connected. If you want just one, probably just better to buy one, if you are like me and want one for each plate (preset to caliber then this will be very cost effective to build a number of them)
This is a really fun project, and when it gets working it is very functional and fits about every press (including the FA X-10 which has almost zero room for a powder check)
