We have featured LED projectors on hack247 before, back then they were still in their infancy, with few modders willing to try them out as a light source. But now with the release of brighter and cheaper LED’s onto the market, people are experimenting and coming up with some stunning results.
This particular project was pulled from the forums at http://diy2005.aa.topzj.com The projector uses an 8.9" lcd and a matching 8.9" LED light panel. The results speak for themselves, the picture looks bright and clear with maybe just a couple of issues on the corners. The benefits of using an LED light source over a traditional Metal Halide source are numerous, less heat, less electricity, longer life and a cheaper price mean that DIY LED solutions are going to be the way forward.
As the site is in Chinese we are struggling to pull any more details from the post, but pictures in this case, definitely speak louder than words.
Check out the forum post for loads more pictures and shots inside the projector at http://diy2005.aa.topzj.com/thread-388160-1-1.html or click on this link for a Google translated version which makes a bit more sense
Here’s a really lo-fi digital to analogue conversion, by printing out his own Super 8 and 16mm film onto transparency’s with an inkjet printer, Jesse England has managed to achieve an arty look for video on a budget.
He took a video clip and converted it using photoshop into individual frames, printed them out using an Epson inkjet printer. These films strips were cut out and assembled into a reel which can be watched in a film projector.
You can visit Jesse’s site at this link or a more detailed set of instructions at this link.

This video tutorial was originally designed for VJ’s who find that venues often have nowhere to mount a projector safely.
This system, which is sturdy and cheap to build, allows you to pretty much mount a projector anywhere you can clamp onto. And whats more, the whole thing looks sturdy and secure. A must for something that often comes in at £1000 or more!

DIY projectors can produce amazing results, but sometimes can lack functions such as zoom and keystoning adjustments.
A Lumenlab forum member who goes by the name of sack4000 has overcome the problem by building a remotley activated arm which mves his projector either 2ft forward or 2ft back depending onthe aspect ratio that selected.
He has also fabricated a remotely operated keystone adjustment powered by a hobby motor and servo…..
Very igenious, and combined with the previously featured Intelligent Controller Board could be a very hi-tech addition to any DIY projector setup

Another example of a DIY LCD projector, this time from Savo at lumenlab forums
A bit of a strange design choice but the image it projects can’t be argued with, and the sheer size of it is impressive alone!
It uses……
- 15″ Samsung 510n LCD Panel
- 400w double sided contact globe Bulb
- 2 evercool fans & 2 generic 60mm fans
- UV Filter

Up until recently LED’s were rejected by both professional and DIY Projector Builders. But recent advancements in LED technology and pricing means that it is now possible to create ultra-bright natural looking images from LED’s
They have the advantage over traditional HQI or MH bulbs in that the heat they produce is dissipated from the rear. This means a simple heatsink and a low-power low-noise fan can be used the disperse the excess heat This leads to a cooler and quieter projector
Check out Tian’s post over at the Lumenlab forums for details of his 896 LED Array which is powering his projector He was selling these arrays on ebay for just over $100 but he has stopped now, shouldn’t be too hard to build one yourself, all the diagrams and parts are listed on the forum thread along with a huge reading list of reference material
In the meantime here are some more LED Projector links for you to check out….
DIYPC Forum Thread - Great thread with a very similar setup, lots of pictures
Mitsubishi Pocket Projector - Commercial LED DLP Projector
Here is an amazing product, its a video projector which plugs right into an existing lightbulb socket on our ceiling, it then uses a
wireless LAN to transfer video content to it.
It also comes with a signal converter unit that allows you to plug a DVI output into your house power supply system to transfer a video stream to the projector.
It looks at the moment to be proof-of-concept, but even at this early stage of production it looks to be a promising new piece of technology
The company behind the ‘Snug Laser Projector’ are called Light Blue Optics and are based in Cambridge UK. You can visit their website on this link http://www.lightblueoptics.com/
The company has just secured 2.5 millions dollars in funding so you can expect to see the laser projector sooner rather than later.
In the meantime check out these videos of the unit, sorry, haven’t been able to find any action videos yet though
You can also keep an eye on their youtube account for more videos as they are released
If you know of any then please get in touch by leaving us an email
We were recently contacted by Richard Choi whos designed the look of the SNUG laser projector. If you want to see some more pictures or check out any more of his work then please visit his website at www.richarDesign.com
Continuing with our long standing obsession with DIY Projectors we bring you this beast….
It has been constructed by Diyeitor who posts over at the lumenlab forums
Heres a quick rundown of the components used in the projector….
- 17″ LCD Panel
- 135mm triplet lens
- 2 15.5″ Fresnel Lens
- 400w HQI Light Source
All this is wrapped up in a MDF housing, although rather on the large size, this projector could easily be built into an unobtrusive coffee table as we have seen DIY’ers do before.
The results are absolutley stunning, check out the windows text, its clearly readable with no sign of any pixels!
This shot from A Sharks tale really shows off the colours and sharpness of this unit
Heres a shot from Need For Speed II Hot Pursuit

Finally, someone taking a different approach to a DIY projector, making it stand upright.
This allows a fairly large unit to blend in quite nicely between two sofas as seen in the picture. It uses a mirror to project the image at an angle onto the wall, this mirror also doubles as a positioning device allowing the projected image to be shone at any height on the wall
It uses a 400W light source and a Toshiba 10.4″ LCD panel
As we have mentioned before, using a larger enclosure also means that ventilation is not as much as an issue, which results in a unit that runs nice and quiet, no more struggling to hear movies anymore!

Once in a while a hack comes along which is a cut above the rest, this particular construction by Brett Fisher is a fine example
Its a DIY Projector and a home meda center all built into a coffee table. The unit not only projects a bright, clear, and in focus image onto a huge screen, but it also displays on a 7" Touch Screen LCD so it can be used as a standalone media center
The whole unit looks extremely professional and you can tell a lot of time has gone into making it. The top of the finished table glows blue and also features a pull out keyboard.
He has used the backlight from the LCD panel used for the projection system to illuminate the keyboard area, no parts wasted here!
The cooling system within this unit is set to auto-cool down meaning you can just switch the projector off and forget about it, it will keep powering the fans for a set amount of time allowing everything to cool down.
This is a great example of a home-built DIY Projector, it is all in one and would be perfect for a games room. The advantages of building the projector in a large case is the amount of room it gives you to work with. Cooling is a lot easier as everything is not as crammed in, ventilation holes are not as much of a problem and fan noise is kept to a minimum.
Making the unit also function as a coffee table is also a great way to make a projector living room friendly!
