I want to build an extremely cheap (but fancy-looking) laser device that mimics a security scanner of sorts. My plan is to buy inexpensive laser diodes, install them on top of small step motors, and have an MCU randomly rotate the laser diode around to give the impression that its doing a sensor sweep.
I found these diodes in amazon, and they're being sold as "modules" that run on a 5V power supply. My first question is, is a driver needed to power this thing? or will a plain old 7805 regulator suffice for this purpose?
