The end goal for this is actually quite stupid. It started as an annual camping trip. First came a laser that could etch our names in firewood (about 3w). Next year I doubled the power and we were able to light the camp fire (6w). This laser was supposed to meet the third year goal: light the camp fire without having to get out of my tent. Unfortunately it couldn't hold a tight beam for the 40 or so feet that would take. So, yeah, mark two.True, but that might be all he needs to accomplish his goal. Maybe he'll see these two posts and elaborate
(And while this sounds really irresponsible and dangerous, the laser can lower bean power to make sure it's actually hitting the fire pit first, fire extinguishers all around, and plenty of OD6+ safety goggles. It's a stupid goal, but I'm not stupid about it).
