I shot this target system in the UK and thought I try to make something like it.
After a lot of searching for a unit that would in some way output to servos I came across the Maestro 18.
All works off a 12v gell battery with a drop down 12v-6v DC-DC converter to run the servos.
4 weeks of building and coding I have this. Very pleased with the final prototype. 7500 bytes of code, 65 subroutines and a lot of headaches trying to write the code. All started with a remote control key fob.
Turning targets development
Self contained in a portable travel box. Remotely controlled from 50m and run from an on board battery supply. Shot off a bench using front and or back rests. A front wooden baffle plate has to be added over the 4mm metal to stop bullet ricochets. Multiple different sequences and target away timings, about 100. 3 seconds target face time.
Match consists of 10 shots at 50m, 1 shot at each target. Maximum score = 60
