Please visit for more information on this and many other projects! As in this episode we will be we will be updating a Radio Shack 12 volt power supply with a variable voltage power buck, banana jacks and several 3D printed to bring old gem into modern times. As the power buck also has digital readouts for both volts and amps making this a handy design to set and calibrate laser diode drivers. Also for under 20 bucks of additional parts this was a real budget saver too!
