Hi guys,
I have purchased this laser module for aligning my telescope.
http://dx.com/p/50mw-532nm-green-laser-module-3v-11-9mm-26889
I am wanting to power it from a PC ATX power supply using it's 3.3V output.
The laser is rated at 250mA/3V so can I treat it as an LED and add a 1Ω resistor in series with the power supply to limit the cuttent?
I know this is not a great solution due to thermal effects etc but will it work?
If anybody has a better solution please let me know. space is very tight in the housing I am using so any circuit will need to be small.
Thanks for your time
