Home Made Projector

Home made projector following instructions from:

Approx 100" (4:3) screen on plain white wall. The camera & the dark video makes the quality seem less. Got the distant correct also, which could make a problem. Light bulb is visible in the middle on darker videos, doesn't annoy that much. Overhead projector is a Famulus Comfort 400, the screen comes from a Hyvision MV141, 1024x768.

Awesome project... quick question though.

How long does it last? and what problems (if any) does it have?

[StrykerTrace]

@jr52990 Bulb breaks from time to time, can't recall how many hours it should work. Problems is more on the aesthetic side, size, placement and such.

[jr52990]

@StrykerTrace so you haven't had any problems with the screen overheating or warping? if not I'm really considering making one of these but I'm just wondering if its just going to break. How long have you been using it?

[StrykerTrace]

@jr52990 The fan helps with the heating, put more fans if you're afraid of overheating. The overhead projector itself has a somewhat noisy fan inside it also, for the bulb. No warping detected. I don't have this setup anymore though but no such problems when I did, can't recall how long I actually had this in use.

Nice work. This ventilator on the left at 0:22 is there to cool this device? Or it's not important background?

[StrykerTrace]

@outslider1 Yes it is for cooling, computer case coolers could be used but I didn't feel like wiring them so I used a regular fan.

And the satisfaction of DIY :)

Look at it this way, a replacement bulb for a projector is practically as much as the projector itself, whereas, a replacement bulb for the overhead projector? £15 - £50.

Nice. 9/10 The one problem I'd say: A bit dark.. but well done! I wouldn't say very many people could make their own, including me :/

But a great job, it does what it needs to do, so your projector mission was a success :D

I just wish I could make my own, if I had the parts.. xD

@StrykerTrace Oh ok... cool. Thanks for telling me, I think I might just use this as my next project.

when i trd to make one the screen cracked when i took the metal case off it

and the second screen got blac blobs because of the heat as it was used for about 3days non stop

@outslider1 overhead projectors get VERY hot, and that is bad for LCDs.
