IR Lighting for Chrony Ballistic Chronograph
thingiverse
This thing is to be added on "ceiling" of Chrony ballistic chronograph. It create an IR cloud upper the sensor, and permit the use of the Chrony in poor lighting conditions. You will need to buy 20 IR 10mm LED, and 1k ohm resistance for each led. Powered by a Li-Po 12v. Battery, but any power source of 0.5 amps is ok. Personnaly, I made some modification to use the metal rods of the chrony as electrical wire to power the IR source.
