The Ben Heck Show

Ben Heck's Battery Charging Circuit (4x52)

:

Ben uses charging circuits in many of his projects so it’s about time he created his own! Ben uses EAGLE to design the PCB for his circuit and shows each step of the process. Ben uses his “laser paint” technique for homemade PCBs then solders on the parts and tests the circuit. Now he has a ready-made 3.7V charging circuit for upcoming projects!
