Design Electrical Circuit to Power a Laser Directly from 120VAC

$250-750 USD

In Progress

$250-750 USD

Paid on delivery
I need someone that can design an extremely compact power circuit that will power up a laser (for example, a green laser pointer that's designed to operate on 3VDC) from 120VAC in the United States. The circuit needs to have a simple on/off function (push button operation) and a green laser. Needs to operate at relatively cool temperatures (and not get extremely hot to the touch). The circuit will end up being encapsulated in plastic once it's made.
