P5 Guy, if you ever upgrade to the Pro 2000 progressive you can always find this and other improvements to that press, on the tacked "Interesting Threads" thread, under "RCBS Mods" at AR.com/armory/reloading.
I plan to improve the tool for myself by having the same micro-controller "count" powder used too, and remind me when the hopper is getting too low. A feed to an optical switch, mounted to a powder cop, could improve that kind of tool as well, with another warning sound.
The point of all of this is that we have more than eyes to see. Why not use our ears to take some of the load off. Progressive reloading is a juggling act that puts most of the responsibility, on the eyes, to see that everything is going as planned. Dillon smartly gives the ears something to do with their powder and primer sensors... This tool can conceivably to all that the Dillon tools do, on one tool, with no mechanical devices to add to powder hoppers or primer tubes. This first one is a prototype that anybody can buy and customize to fit their own press, and the price is way less than I thought it would be.
