That looks awesome, I wonder how hot the case/internal parts get. He seems to have that covered with a computer fan. What I liked about it was the fact that it was instant on, even with the time it took him to turn around and turn off the lights most professional projectors would still be “warming up” or what not. Nice Hack!! :)

Not clicking on an instructables link. Great build though, congratulations!

Wonder how it would look if recreated with a Sony PSP. Resolution would be decent, need to look up specs I guess. I’m sure the pro duo port could be swapped out to read media from a larger variety of sources as well

I wonder if I can hack my current projector when the bulb finally dies. It’s way over the 2000 hr mark and it’s still working (Optoma EP770). It’s supposed to have 3000 lumens but I’m not sure if this bulb gets dimmer over time or not. Maybe an upgrade to a higher wattage LED bulb can work… worth trying versus buying a $250 bulb replacement on an old projector. Then I get to keep 1024×768 at less than $100 :)

Nice on the stand alone factor. I havent seen a portable dvd player with usb yet.. Instructables is gh3y because they make money off of other peoples hardwork. I have to pay to see the project on one page? knowledge is supposed to be free!

you do not have to pay to see all of it on one page (unless it changed in the last week or so). You just need a free (as in beer) account.

“they’re only about 15% efficient in producing light”

And that’s only part of the story. LEDs, like most types of lighting have an efficiency that varies based on the scale of their power rating.

In the case of LEDs, their efficiency tends to decrease as their current (and power) handling increases.

This is where the big challenge lies in producing high-power LEDs for general lighting purposes… they tend to be notably less efficient than their low-power counterparts, and even less efficient than other ‘white’ lighting technologies such as fluorescent, induction, and Metal Halide lamps.

hm, probably shoulda thought out my comment before clicking submit…
for anyone who doesnt want to click instructables, his entire build is documented in youtube!

I agree with the instructibles hatred… They’ve just been getting more and more evil as time goes on.. They take other people’s free content and put it behind paywalls, sometimes even locking the original author out of using it… I’ve read forums where the author of an article is not a “pro” user, so they’re not allowed to view their own photos, read their own annotations, or download their own PDF. Sure, if they made their own content, like, say, makezine, sure, they’d have every right to lock people out of it and make people pay to view it.. But taking people’s CC and GPL licensed works, claiming ownership of it, and locking everyone out of viewing it unless they pay, is, I think, contrary to the whole spirit of their site. They also censor anyone who mentions anything about this, and they bribe authors to remove negative comments, either financially or by offering them better placement on the front page.

Sorry, it looks like a very nice projector, and I’d love to know how it was made, but I cannot click the link.

I am not a man to abide whining (unless I am the one doing it…).

The people that put their stuff on Instructables did so on their own.

You can always start your OWN website to counter Instructables. It’s easy to do these days, and you can either charge (not popular, evidently) or not. You would probably make plenty in plain old ad revenue, but some people might that that THAT was a bad thing, also. Any way it’s done, you will have to pay. If you rent server space, host at home, if you connect to the internet, somebody is paying.

Failing that, you could put a photo-spread on Flickr or video how-to’s on YouTube. Google will appreciate your hard work, they will make the money, and they will get usage information from anybody connecting.

Yes, “information wants to be free”, but people have to pay for the transmission. So quit whining about Instructables and come up with a better idea. Then we can whine about your efforts.
