Awesome Felt Speak and Spell, Speak and Math + Others
GetLoFi continues to have amazing finds Circuitmaster writes - "Telephone1562 has posted this Arts and Crafts version of a popular circuit bending candidate Speak and Math to LiveJournal Circuit Bending Group. The felt does nothing for the glitches, however it does make your speak and spell warm and fuzzy to the touch... To take this Speak-Tacular a step further here is a link to a Sherman filter bank triggering sounds through some bend points on a Circuit Bent Grillo Parlante ( Italian Speak and Spell ) by Asmoeddie. Blinky Blinky, Glitchy Glitchy." - Link.

Snap circuits electronic educational kits
We've mentioned this kit before, but here's more about it, a simple "snap together" kit for kids... -
"Snap Circuits electronic educational toys make learning electronics easy and fun! Just follow the colorful pictures in the included manual and build exciting projects, including FM and AM radios, digital voice recorders, burglar alarms, doorbells, and much more! You can even play electronic games with your friends. All parts are mounted on plastic modules and snap together with ease. Enjoy hours of educational fun while learning about electronics. No tools required." [via] - Link.
Last year one of our makers had this to say about the kits I bought a Snap Circuits Jr. for my daughter a while back. The snap part of it could be made a little better. But, the overall kit quality is very nice and the instructions are easy to read to with good diagrams. Elenco /Snapcircuits also has additional projects on their web site.
Have other good electronic kits? Send'em in!

HOW TO - Make a pinch valve
Annina writes - "This is a simple way to control the flow of water via a microcontroller or similar. Most commercial irrigation valves require a certain amount of water pressure. This valve is designed for low water pressure. It is used in the eRiceCooker project, a fully automated system that cooks rice according to the frequency of news reports about genetically modified rice. " - Link.

HOW TO - Circuit bend... a computer!
Get LoFi shows how to "circuit bending" a computer, nice! - "Computer Bending Yes, it is possible. I always wondered what would happen if you start circuit bending a computer. The obvious answer is that it will crash. Indeed it is not very good to cross pins on the motherboard. However this does not always hold true for the Video ram chips. My original idea was to start bending the video inpired by some Nintendo Cart bending that I have seen. The ISA video card which I began experimenting with had 512kb chips in individual sockets. The initial exploration yielded interesting results, scrambled video, aliasing, noise. Great!" - Link.

Brian writes - "The monome 40h is a reconfigurable grid of backlit buttons-- the firmware is open source, and we encourage hardware hacks. We've also posted extensive documentation on our prototyping and production process in an effort to inspire similar projects. We're basically a bunch of post art-school/engineering makers, sharing our love for interface." - Link.

Cat detection/repellant device - Timer delay circuit for motion detection system
Design News has its latest "Gadget Freak" - this one is a motion detection system that will turn on a sprinkler to scare off cats, varmints (and others) off your yard... Hap writes - "I had a problem with cats (and other small animals, armadillos, etc) getting into our flower beds and causing "undue stress" to some of our favorite plants. The cats are very helpful because they cut down on the number of small uninvited rodents and reptiles, but the flowers needed some protection.
Not too long ago I had seen a floodlight motion detector connected to a sprinkler to discourage deer and other animals from raiding a garden. I had recently installed a sprinkler system, so I purchased a wireless driveway alert system and put the two to work. To allow enough time for the sprinkler valve to open, build pressure, and activate the sprinkler head, he constructed a time-delay unit from an old standby 555 timer. It activates the sprinkler valve with ac power from the control for 10 to 12 seconds -- allowing plenty of time to open and apply a good H2O dousing to varmints and wayward mailmen alike" - Link.

HOW TO - Scorpion detection using ultraviolet (black light) LEDs
John writes - " Some time after reading "A Powerful New Light Source for Ultraviolet Detection of Scorpions in the Field" I decided to build my own scorpion detection device instead of buying an uv flashlight. I ordered fifty 5 mm UV LEDs (light emitting diodes) at the website of LSDiodes." Thanks Paul! - Link.

HOW TO - Luxeon LED caving lamps
Wow, this is a really nice design... - "Speleogroup is experimenting with circuits for driving high-power LED devices, such as the White LED Luxeon Star from Lumileds ». This device is rated at approximately one watt, giving typically 18 lumens at its rated current of 350mA. Their high dome Amber Luxeon star gives 36 lumens at a similar power, with a colour similar to that of a sodium street lamp.
To use these devices safely at maximum power, and provide switchable power levels, it is best to use a constant-current circuit. To maximize battery life, we are investigating switched constant-current circuits using off-the-shelf power control ICs and microcontrollers.
This page describes one circuit we've developed, using the Atmel » ATtiny15L microcontroller. An earlier design used the Linear Technology » LT1512 chip, a current mode switching regulator. " [via] - Link.

HOW TO - Make a telephone handset microphone

Wide-ranging fields have been revolutionized -- or even made possible -- by microcontrollers, including industrial robotics, automotive engineering, special F/X, irrigation, interactive exhibits, motor control, and all kinds of research. For a long time these powerful chips, and the tools required to use them, were so specialized that few people could explore their potential without a formal background in electronics and software engineering - Get one at the MAKE store - Link.

I got the parts bag from Solarbotics and scavenged a VCR from someone I work with. I've built a bunch of robot kits in the past, but I have to say that starting out with a pile of junk and some components and getting a working robot out of it brings a much greater sense of accomplishment than any of them ever did.

I haven't seen these in person, but the e-puck education robot looks interesting... (anyone poke around with these?) - "This project has been started at the Ecole Polytechnique Fédérale de Lausanne as collaboration between the Autonomous Systems Lab, the Swarm-Intelligent Systems group and the Laboratory of Intelligent System. The main goal of this project is to develop a miniature mobile robot for educational purposes at university level. To help the creation of a community inside and outside EPFL, the project is based on an open hardware concept, where all documents are distributed and submitted to a license allowing everyone to use and develop for it."
