Bit Editions is offering a $235 LED kit for artists – you send off your own animations and then assemble the kit to display your LED-ified art. The displays are 12 by 14 inches in size. They contain one LED per square inch. Each LED can show eight levels of brightness. Driven by a microcontroller […]
Ami on Coolhunting has a post about a Maker-friendly book I think I’ll order “Taking the D.I.Y. revolution one step further, Design It Yourself is the indie entrepreneur’s bible for how to design a wide variety of business basics, from press kits to wall graphics.” If anyone has read it, post up in the comments […]
Edmund Scientific’s has a deal on kits for kids -subscription style…“Edmund’s Young Engineering Kits Program – this program consists of three fun and educational hands-on activity kits that will help the young ‘engineer’ to experience, create, and learn different aspects in the vast field of engineering! The kits will be shipped individually every other week to give you something to look forward to during this winter season. The Young Engineering Kits Program is a subtle and creative way to expose young persons to.” Link.
Eltoozero of www.destruc.tv writes “I built this case mod to be a nearly completely authentic looking Mac Classic, but with a Mac Mini inside, playing DVD’s through the floppy and running OSX, except it’s black.” Eltoozero said he’d write up more about his project if there is interest, so post up in the comments!

Krazydad writes – “I decided a few weeks ago to build a wooden gear clock because I wanted to understand the clock mechanism better. There are a number of websites that offer plans for wooden gear clocks, but as someone with absolutely no woodworkng experience (band practice generally interferes with taking shop class), and no tools, I needed something that was ready to build. I found three sites that offer such kits…” Here’s a review of the Ascent Wooden Gear Clock kit. Link.
With our kits you can capture high-speed events, splashes, popping balloons and breaking glass. It’s an adjustable flash controller triggered by light or sound. Our kit includes a high-speed flash, disposable camera, flash controller and fully assembled flash trigger that synchronizes the high-speed event and the flash. Also included is a 6-ft cable connects your high-speed flash to the flash controller, and all the tools needed to precisely time your high-speed picture. Flash controller is adjustable, so the flash can be triggered by soft sounds, loud sounds, a laser pointer, or a flashlight. The kit also includes digital output that can trigger other external flashes, such as the SnapShot II strobe light. But, how do we test each unit before we ship them? Here’s great video with Tom Anderson from Quaketronics showing you what we do! Link (MP4). Click here to get the video with iTunes! This video should work on PC/Mac/Linux/iPod video and PSP (let us know if it does not).
We’ve had a few emails and posts about folks who wanted to build their own lie detector, here’s one (and how it works) – “The circuit diagram of the Lie Detector is shown above. It consists of three transistors (TR1 to TR3), a capacitor (C1), two lights or LEDs (L1 & L2), five resistors (R1 to R5), and a variable resistor (VR1). Suitable transistors to use are BC547, BC548 or BC549, or any other small NPN transistor. The Lie Detector circuit works based on the fact that a person’s skin resistance changes when they sweat (sweating because they’re lying). Dry skin has a resistance of about 1 million ohms, whereas the resistance of moist skin is reduced by a factor of ten or more.” Link.
