How can we hack these (I have a Merlin Pico)to get higher brightness , HW and SW aspects ?

I have one of these, they work ok apart from not being able to charge it over usb when its on. Wondering if there is some sort of hack to allow it to run when charging.

in theory you could install a 10W LED in there, if it would mechanically fit. Interestingly the full power may not be required and I also found a trick involving glueing with UV glue a bundle of TOSlink cables to the emitter allowing the light source to be located elsewhere.

Another useful technique is to “drill out” the centre of some 20,000mcd white LEDs and glue a fibre with UV glue, this couples around 70% of the light into the fibre. Tried with cyano and its not quite as effective.

best glue to use is the “uv glue” in the red tubes off Ebay, sets in under a minute outdoors. It owns for glass joining too.

I am currently doing a DLP LED mod as someone has kindly unloaded some broken projectors with burned out bulbs (180 UKP is insane when 100W LED is only 60 UKP…)

Peace.

So, could it be possible to hack the 3m brighter, since brigtness seems to be the main issue with the projector? By adding or changing leds for example? Please make a hack for this!

Electronics Goldmine has a couple of surplus DMD devices (which they call “MEMS assembly”) One is here: http://www.goldmine-elec-products.com/prodinfo.asp?number=G13751

So, um, does anyone have any information about how to DRIVE one of these things? I bought one a long time ago with the idea of maybe getting it to “shimmer” as a stand-alone device, but TI is noticeably silent when it comes to anything actually resembling a datasheet for these things.

Here’s a challenge I propose… one of you hackers should take two very small LCD screens and make some video goggles on the cheap… and post some instructions on how to do so =)

1…2…3… go!

Great, now they can get a move on making cheaper projectors, minimum 720p under $300.

Maybe when the parts or the tech gets cheap enough we can have DIY LED projectors.

Nice find, but I don’t like the way the article is written in a journalistic fashion full of vague statements with the occasional well thought out quotes from “an engineer”. I’d prefer if the engineer just wrote the article to begin with…
