if you want to build a cheap projector you can get kit systems from china and use one of your own lasers. there is info floating around too on freeware and info on converting sound cards to control the said china scan engines, thats kind of where i am sitting at now. I too started with flash lights then found LPF My first higher power 532 laser i bought in 2003, sadly i think i killed it trying to use it off of a power supply, it's only victim was a bug that happened to be in a engineering lab i worked at back in 2003, people got a kick out of till the burned bug smell permeated the lab but that does get boring, displays are where the fun is at now. I have a 445 pointer that i think i am going to use in a projector when i can get the cash for the correction prism set. My truck i drive only has front brakes so i am saving my penny's to buy the line when it gets a bit warmer, I am in Michigan so every thing on a car corrodes in record time. I like working on my own stuff and almost became a mechanic but bending line while on wet cold ice is no longer my idea of fun. lol.
nice to have you on the forum!
