HOW TO - Man an almost-no-solder electronic organ
Mark writes -
You remember Field of Dreams, the baseball fantasy movie where Ray Kinsella heard a voice that whispered, "If you build it, they will come," don't you? Well, ARRL Education and Technology Program Coordinator Mark Spencer, WA8SME, has come up with a successor to his No-Solder Code Practice Oscillator project that--if you build it--is sure to spark delight and interest in children.HOW TO - Man an almost-no-solder electronic organ - Link.

HOW TO - Make a color sensor from a reversed LED and Op amp
David writes -
One of the first lessons that an electronics student learns is that an LED provides light from current flow. But, did you know that an LED put in backwards provides current flow from light? Yes! It's true.HOW TO - Make a color sensor from a reversed LED and Op amp - Link.

TV-B-Gone tampon case
I had some extra real estate in my tampon case, so I assembled my new TV-B-Gone kit inside. I pulled out the button and aimed it slightly downward, so it can be activated by items on a table like the base of a wine glass or silverware, for going incognito in a restaurant. - Link.

Interview with Johnny Lee
Alan Parekh, of HackedGadgets, has a short interview with Johnny Lee, the computer engineer whose Wii remote hacks we (and everybody else on the InterTubes) have blogged about. Johnny also created the popular $14 Video Camera Stabilizer project featured in the premier issue of MAKE.
AP: Your Wii projects have been taking the Web by storm! What attracted you to the Wiimote as your interaction device of choice?JL: Well, I was excited by the Wii Remote ever since the original press release about its capabilities was public. Ironically, I was an intern at Microsoft the summer before the Xbox 360 was launched. Several internal people, including me, were still trying to convince the Xbox group they should put an accelerometer into the controller. That, of course, didn't happen. The Wii remote is one of the most sophisticated input devices available today and an amazing piece of engineering containing an accelerometer, camera, and wireless communication. Combined with the ease in which you can connect it to a computer made it an obvious choice for experimentation.
AP: Have you had any discussions with Nintendo? Do you think they could use some of your techniques to enhance their console?
JL: I have not formally had any contact with Nintendo about this. I speculate that the Nintendo engineers who developed the controller probably knew of this technique, but probably passed on the idea or were saving it for a later product launch. But, these ideas can definitely be used in a Wii title assuming they would be willing to bundle a little bit of new hardware with it. I know several game developers are starting to look at the idea. Hopefully, the game concepts will make it all the way to market.

WebVisitors blinker is a quick 'n' dirty Arduino project. Something very easy to do to get started with Arduino.

HOW TO - Make a cockroach shocker
Mondo made an "electric roach motel" -
Using a PIC for this device provides a lot of useful functionality. The timing for the power pulse to the inductor is critical to getting the best Zap from your nine volt battery. The longer the current is on, the higher the voltage. Once the inductor reaches saturation, however, you are just wasting power. Some versions of this circuit charged up a capacitor (C1) with multiple pulses. This allowed the PIC to monitor the high voltage and produce a regulated output. Here is the current Source File. The version shown here just generates 400 volt pulses at a rate of 10 per second.HOW TO - Make a cockroach shocker - [via] Link.

Uber tracker and GPS eval boards...
Some new GPS action over @ SparkFun -
It's not quite small enough to track your cat, but the Uber Tracker is a beast of a product. This device may seem simple enough: get GPS coordinates and broadcast those coordinates over the cellular network - but it's so much more! The Uber Tracker has open firmware and hackability. It's also completely PTCRB and FCC certified meaning it is fully licensed to operate on any GSM network in North America. Configure the unit, power it up, and you'll get an update every few minutes of the device's position to your phone, your website, or your SQL database. Could you track your car? Sure. Ever wonder where your donated clothing goes? What about biological samples? It's 'big brother' - but you get to play the older sibling's role.SparkFun Electronics - Link.
The evaluation board using the ET312 SiRF III GPS receiver is finally done! This board will allow you to play with this very small but powerful GPS receiver.

The stribe - touch-sensitive mixers with a LED matrix
Interesting touch-sensitive mixers with a LED matrix under the faders, Soundwidgets writes -
The Stribe's original name was "xenome" - a nod to Brian Crabtree's amazing monome 40h project, which inspired me to build the first Stribe in the summer of '07. For many years, I'd been thinking about and experimenting with alternative interfaces, but it was Brian's monome 40h that made me realize such a project could be successful without needing to be "discovered", then manufactured and marketed by some huge conglomerate. Along the way I changed the name to avoid confusion and to more accurately describe the Stribe's function. Stribe means "stripe" or "striped cloth" in Danish.The stribe - touch-sensitive mixers with a LED matrix, thanks Felixe! - Link.Because Brian's monome is an open project, monome.org contains tons of great information including schematics for their circuits, the firmware source, the Max/MSP applications... everything is there to study and learn. By poking through their designs, circuits and code, and the freely provided
"how this works" Max/MSP examples, I was able to understand the basic ingredients that would be needed for my own project.

Drag bike micro-controller shifter and NOS control
ChrisP writes -
This started as a project about 2 and a half years ago when I started drag racing motorcycles with a friend who has a bike shop. The original project started as how to make things more efficient, easier on the motorcycle and of course more constistant. Of the bikes we race the fastest when pushed to the edge has been 7.92 seconds at 181mph if I remember the mph correctly, it consistantly runs 8.05 to 8.15 seconds in the 170's so obviously safety is paramount. Now of course this is the disclaimer that has to come with posting a project like this. Racing, Air Shifters and of course Nitrous Oxide can be very dangerous even in a well maintaned and planned system. I highly recommend that only individuals with full understanding and experience work on or operate either of these systems and claim no liability for there use. With that said, on with the project.Drag bike micro-controller shifter and NOS control - [via] Link.

Multimeter clock
FunnyPolynomial squeezed a modified LEDkit.biz red LED clock into a stylish Digital Multimeter case! - Link.
From the Maker store:
With the LEDkit™ solderless clock kit, you create a giant -- 9" x 5" -- super bright self-standing clock only 1/8" thick that keeps accurate time -- even during power failures up to 1 minute. Change the brightness at the push of a button. The digits fade smoothly when the time changes -- minimizing distraction. Automatically synchronize multiple clocks. Easy to assemble & no soldering required! The unique wiring pattern doesn't need a traditional PCB with tiny parallel tracks on it. You simply twist the LED leads directly to other leads. Only six conductors enter the panel! Also available with Blue LEDs. Requires 60Hz (USA/Canada) electrical power. LED Clock Kit -Red - Link.
