The DIY LCD Projector Project. Cut price, cut fingers?   The principals that make projection in general possible are very simple in concept. You need simply 4 requirements to be met: a light source, the brighter the better; some form of imagery medium, film or LCD it’s all the same conceptually; a focusing mechanism to help provide a crisp image; and finally a display medium.

How to build your very own automatic book scanner using an eraser, a few bits of LEGO, a laptop and an upside down Epson flatbed scanner. It’s slow yes, but think of the long term implications…[Via GizmoWatch]

Canned Goods Production Machine. Cool stuff, peeps, create your very own 1 minute per can factory production line in the bedroom. Think of the fun you can have (geddit?) coming up with new products to sell. Hair clippings, belly button fluff, London Fog (a sure fire winner with folks from Arizona I believe), or even corned beef from King Arthur’s Square Table. Knock up a quick web site and bingo, you’re an Internet zillionnaire. The unit costs around $253.00 in yen like substances…

Hmm…just wondering why you’d want to embed a full blown LCD screen into your desktop computer? New definition of luggable computing? No desk space? Or just because you can? Answers on a Segway television please to….   All the materials for this project are easily available. Costs are moderate on this project because lets face it, LCD’s aren’t cheep yet. I am sure this same rig can be made much cheaper, there are many surplus outlets that have used LCD…

Create your own stun gun from a Kodak disposable camera. Er….? Usual caveats about roasted body parts apply.  Because this isn’t very safe and you have a chance of getting shocked, (personal experience) an easy way to make a protective case is to. Step1) Cut apart the hard plastic inside of a “Five Star” binder. The tough plastic is very flexible and and can just be glued together.

‘Turn any good quality photo into a full sized cardboard cutout’ at home using this $29.95 e-book. From the sad-but-true department. Usual caveats about rain, sharp scissors and general nerdiness apply.  Your games room looking a little boring? Your bedroom needs to be more “fun”? Missing your girlfriend or grandkids? This has to be the solution! All you need is your color printer, some stationery, a few stationery tools and about an hour of your time.

Build your own RFID Zapper out of a cheap disposable camera and confuse the bits out of your local superstore. Or police station. As you’ll likely be invited to visit there shortly.  To keep the costs of the RFID-Zapper as low as possible, we decided to modify the electric component of a singe-use-camera with flash, as can be found almost everywhere…It generates a strong electromagnetic field with a coil, which should be placed as near to the target RFID-Tag as possible.

Build your own game seat rig. Save yourself a bundle and craft your own driving simulator chair. Who knows you may even have fun.  Unless you want to mess with all the wiring and supplying 12v to it, etc., just avoid power seats. If you really wanted to do a power seat, look for one that has the controls in the seat itself (as opposed to the door or center console) so you don’t have to figure out how to…
