[jenner6989]

so i got bored with my stuff latley and i decided to turn this little rolling truck in to a laser.i have two handheld's and one labby. so what i would like some feedback on a batt/ power source (12v) and what would be a good heatsink for this? i already have a fan installed. I am gonna have the laser coming out the front of the truck. also need to place a plug to charge the power source and a on/off switch and a push button momentary switch. (i.e.-as in the pic of my phr labby included) any sugg would be greatley appriciated!! pics:
