I've ordered all the parts for this" styropyro and I was wondering what a good host would be. I don't really have much experience with this type of thing, but I think it would enjoyable and a good learning experience to build a laser. Also, is it easy to set the current for this Micro-Drive V3 adjustable driver (assembled) - $13.00 : rkcstr.com, Micro-Drive and laser diode electronics ? Thanks
