Oh come on, you have to be kidding. All they did was cut the top off a lamp that had a metallized reflector to direct more light downwards, they are used for porch lights etc. Just score the glass with a diamond point and crack off the unneeded parts. Not complex at all.
you have got to be kidding me!
glass cracks. i have delicate but strong hands...look up my hand in the palmistry book and it will tell u the hand of a artist, builder, healer,worker. i have good hands if not the best. THIS GLASS WILL CRACK IN MY HAND if i try to do anything to it..that guy baked it socked it drained it, glued it sawed it etc he has a lot of tools etc which he failed to mention 🙂 and the great part is its in german!
hey now forget building diy projectors i just stop building my 3 other projectors so i can half translate and find the parts i require in england!!
like i said u have got to be kidding me. i have designed a better light engine than most i will post pictures soon. thanx

You never recycled old light bulbs for use as boiling flasks for chemistry experiments as a kid? Light bulbs are surprisingly strong, plus you can buy "heavy duty" bulbs that have thicker/stronger glass.
no as a kid i wanted to fly a ufo and as a adult i'm building one! but the point is glass cracks and is dangerous..only for the very experienced and plenlty of time type person. thanx
whats the brown stuff he has around the bulb? im assuming its to prevent the glass from cracking as he cuts it with the dremel..
I think a rectangular (4£º3 or 16:9, depending on the lcd panel you use), funnel-shaped reflector is the most efficient one.
