we have had a few PM s
and i think all he may wont to do is two effects one beam one fan i do not know if he will need any where near 400mw he also may not need galvos or software so his cost may be lower he will need to learn quite a lot
but he has all the info here in front of him

( no where can you learn as much about laser shows than this forum )

i am glad he is here trying to learn no just buying junk off ebay and maybe harming someone

we do take lasers and laser safety very serious not so sure if people realize the time a lot of people spend here to help

we will be getting together soon to look at fixed effects and horizontal only galvo sweep old school and also pango fb3 with x y scanners i have one of DZs gm drivers so he can have a shutter with all CDRH in place if i help with it

hope this just started bad and will end with all happy

keep the lasers lit !!
