i actually think its a good idea
to a point.
HOWEVER-
99.9% of the info is already on this forum. and whats good about that is that when you spend time researching it and reading others peoples experiences and advice, you end up learning a HELL OF A LOT more.
unfortunately, ESPECIALLY in this business, mistakes will be made. we ALL have fried power supplies. or diodes. or got burnt, or...ahem....stripped wires with our teeth while the power was still plugged in...ahem, cough cough...(sound familiar anyone?)
and there really is no "step by step guide" to how to build a laser projector. i think a general guide may be a good idea. but there really is no definitive way on how to build a laser projector step by step.
not to mention, if there WAS such a guide, it would be pages and pages and pages long.
my suggestion (and most everybody elses probably) will be to do as much research here on your own. not becasue we dont want to help you. in fact we all love helping as much as we can. but one of the most valuable tools you will gain from this forum is the vast knowledge of information and details involved in these pages.
reading others peoples experinces and successes and mistakes and triumphs will help you IMMENSELY. and of course, when you get stuck, we all will help you out.
if you have specific questions to get you started, feel free to ask.
