    Projector Bulb Conversion To LED

    Best way to do a bypass would be to buy one of these cheap chinese bulbs (you know, the ones that burn out in a month and are dimm as sh*t but cost 20$ instead of 300$). Those things are made of A the bulb and B the bulb's circuitry. Bulb's circuitry is what sends the ok to your projector. If you can find a way of taking out the nasty bulb while keeping the circuit active, you have yourself a bypass at no risk to your projector. At 100W for the LEDs, you may even be able to use the projector as a powersource if you can figure out what to do with the excess power.

    LED Projector Lamp v.2.0

    Hey, very interesting projects. I'm thinking of doing it myself and here are the things that I would do differently. Maybe it would get you unstuck:First off, cooling: LEDs run much cooler than the incandescent bulbs that are usually used in these projectors. Your LEDs run on 22Watts of Power whereas a regular projector bulb can run on up to 200W. The fans of the projector are designed to dissipate 10 times more heat than your LEDs produce, so the whole heat sync assembly is overkill, just line up your LEDs with the air flow of the projector fans and that will keep them nice and cool.Now onto focusing the light. I was trying to brainstorm how a 120o light can be focus. I drew you a diagram of my idea. Forgive my bad drawing, I'm not a good drawer and I'm getting used to the tablet and t...

I was trying to brainstorm how a 120o light can be focus. I drew you a diagram of my idea. Forgive my bad drawing, I'm not a good drawer and I'm getting used to the tablet and the new drawing software. The basic idea here is to have in a little light well or cone made of some reflective material that will redirect the wide angles of the light. You can figure out the angle of the cone mirrors by taking a taking a normal mirror and playing with the angles until you have the light focus you want.I think this is a great project and even though you may spend something similar to the price of a new bulb, consider that your LEDs will last you 10 to 20 times longer than an incandescent bulb and spend 10 times less electricity. Epson charges 350$US for a new bulb and they rate the bulbs at 4000hrs but alot of people in the forums say that they only last 1000. Your LEDs are rated for 50,000 hours.

    The Nova—A DIY Oculus Rift!

    Awesome project. Been a couple of years. You still using it or did you move onto a Rift or Vive since then? If you haven't and are still use it, did you figure out a way to get your dRift to work on SteamVR?

  • How to build a 24V Power Supply from 2 ATX PSU

    I'm very interested in this design but there is one problem that I see with it: the parts of these psu were rated for a specific amount of Watts. By putting the second one in series, I'd be doubling the voltage and the overall wattage that's being loaded on it. These actually expensive psus I'm working with and I can't afford to blow one up. How does one go about verifying if the PSU can handle the doubled wattage?

    Yeas, but even though the amperage stays the same, the total wattage is doubled b/c voltage is doubled, if at some point down the line he halfes the voltage with a resistor, he'll have double the amperage.
