[john] sent in his uncles Keybot project. The device accepts input (a parallel port in this case) and generates standard keyboard output. It allows a computer to create its keyboard input for itself or another machine. Personally, I go for serial consoles, but it’s a good study of our old friend the keyboard. (If legos are more your thing, you could do something like this.)

Reactable: Visual, Interactive Synth
[imajes] brought this sweet project to my attention. The table is reactive thanks to the combination of a projector and a video camera below the surface. The position and unique pattern of each block on the table is used to manipulate the operations of the synth. The software is open source – so you can build your own. (And it’ll run on linux, mac and windows) Check out the videos for a good demonstration. I’m thinking that one of these could be built on a budget using lumenlab/overhead LCD technology.
Optical Recognition LED Control
I probably shouldn’t find this as worthy as I do. It’s the optical recognition equivalent of wiring up a LED to a switch,, but it just appeals to me. [Ashish], one of our favorite optical recognition hackers of late, sent along this product of his boredom. If only he’d give us some source and a wiring diagram…

Watercooled LED Backlit LCD
[john] mentioned this on the LCD LED backlight post. Given the date on the posts, I was surprised that we haven’t seen it before. He replaced the CCFL lamp with 32 1 watt luxeon LEDs mounted on a custom copper water cooling block. The result is bright enough to be sunlight viewable in his car.
RS-232 Serial Laser Link
[ashish] sent in this one via the tips line. (Ed Note: link rot. Try this one.) It’s a project to create a laser based RS-232 link. It’s based on cheap laser pointers, a MAX232 and a photo-resistor to receive the signal.
Magnetic Strip Resistor MIDI Controller
[Joel] sent me a tip where I discovered this fun hack. It reminds me of the old pencil lead resistor trick. It looks like Ableton Live has been inspiring quite a few original controllers.
From the post: (Myspace doesn’t seem to have individual post linking)
“If you REALLY want to do this, the code is here. It is sloppily written in PASM for the Ubicom SX microcontroller running at 50Mhz addressing an ADC0808 (datasheet) 8 bit parallel ADC, because it’s the year 1993.”
Make Your Own Laptop
[Richard] pointed out this mini-itx laptop. The idea behind this particular design is to enable upgrading every component as needed. The case is aluminum, and the wiring inside is an exercise in patience. It’s not the first DIY laptop we’ve seen, and it doesn’t have batteries, but it’s the first I’ve seen with two internal hard drives.
Update: There is a battery, it just gets very little mention. It’s hiding under the DVD drive and one of the hard drives. Anyone know what kind it is?
