LM317 adjustable current source/regulator

Adjustable constant-current source I designed for things like laser diodes. Full details at: http://imajeenyus.com/electronics/20160530_adjustable_current_source/index.shtml

More details on the grounded-wiper potentiometer feedback network: http://imajeenyus.com/electronics/20160517_potentiometer_feedback/index.shtml

This was used to power a 300mW 808nm laser diode on the AxiDraw drawing machine for some rudimentary laser cutting: http://imajeenyus.com/computer/20160531_axidraw_laser/index.shtml
