Laser pointer on with Masso

Hey Loopback77,

@Loopback77

I’m an electrical dummy, but I wonder if it’s possible to use the 36VDC from the Onefinity power supply with a resistor to get 5VDC for the laser

A resistor wastes the voltage by transforming it into heat. What you would use is a DC-to-DC converter. They have a reasonable electrical efficiency. You can get them everywhere.
