OpenFM's Open source radio transmitter
OpenFM's Open source radio transmitter -
When Adapted Consulting's co-Founder, Frederic Renet couldn't find a commercial radio that was energy efficient, easy to repair and affordable, he decided to build his own. These requirements were crucial for where he was installing radios in rural Africa. Based on that first model, Fred has designed a new radio that we call "Open FM".Main Page - OpenFM - [via] Thanks Terrie! Link.Adapted's OpenFM radio kit is a low power, affordable open source solution created for use in remote areas. The system is robust and was designed to withstand harsh weather conditions, including high temperatures, dust and humidity. It has been optimized to be energy efficient, allowing it to operate using solar power and so is particularly well suited for rural environments that lack dependable electricity.

Make a USB power/charger from a wall wart
A user on the Hacked Gadgets Forum posted this simple conversion of a common wall-wart into a USB power supply/device charger. He used the power adapter from an old Iomega drive and a few common components. I've seen several versions of these floating around. Easy to make. Nice to have around.

HOW TO - Build a laser effects show
YouTube user Starcross42 has been uploading a series of great vids on laser effects for shows and how he achieves them using commercial and homemade laser tech. He has seven "Build a Laser Effects Shows" on YouTube. Be sure to check all of his videos, which include some other laser-related and other cool science and technology pieces. Starcross42 is a high school physics teacher, the kind you wish you'd had.

Stealth-ifying your wireless mouse receiver
Harry Andreou, a Dutch programmer, got tired of looking at the bloated receiver for his MS Laser Mouse 6000, so he recased it... in a thick magazine. Now that choice might be a little... different, but you can recase it in anything you like. Get creative. Liberate your tech from its drab little cases.

Using an ADXL330 accelerometer with an AVR microcontroller
Evil Mad Scientist Laboratories writes -
The last decade has seen more than an order of magnitude drop in the price of accelerometers, devices capable of measuring physical acceleration (often in more than one direction). History suggests that whenever a useful technology makes a precipitous drop in price, unexpected applications follow, and that's exactly what has happened in this case.Using an ADXL330 accelerometer with an AVR microcontroller - Link.Starting from zero and summing up acceleration, you can use an accelerometer to find velocity, and from that derive relative position information. By measuring the acceleration due to gravity, one can also determine orientation (technically, inclination)-- you can tell which way it's pointing. Those are pretty useful skills for a chip! And so as bulk prices for tiny chip-scale three-axis accelerometers have begun to approach $5, they have started to appear in all kinds of mass-market applications that you might not have predicted: laptop computers (for hard drive protection), smart phones and cameras (for orientation-- e.g., portrait vs. landscape on the iPhone), cameras for image stabilization, and quite visibly in the controllers for Nintendo's Wii system.
With all that promise, you might think that an accelerometer is a difficult beast to harness. That turns out not to be the case. In this little project we demystify the mighty accelerometer and show you how to get started playing with one. In the spirit of hobbyist electronics we do this the easy way-- without designing a PCB or even soldering any surface-mount components.

HOW TO - Getting started with Arduino
A SUPER article up on CRAFT from R.Stern! She writes -
I've compiled a brief tutorial on getting started with Arduino for the absolute beginner. I'll cover where to learn, what to buy, and where to go for help. Why should you crafters be interested in Arduino? The Arduino platform, more-so than any other way of incorporating electronics into your projects, is geared towards do-it-yourselfers. It's open source (both on a hardware and software level), so the community plays a large role in its development and improvement. Crafting is a community endeavor; individuals share tips, tricks, techniques, skills, and materials all the time. Arduino comes out of the same spirit. On a more practical level, you may just want to make your crafts more fun, interesting, and interactive by introducing some lights, motion, sound, or simple sensors. Stuffed toys can become glowing night-lights or cat-chasing robots, fibers can carry currents to make smart clothes, accessories, you name it. There's also an overlap in materials between crafting and circuit building that can lead to some non-traditional works in either category: threads, fabrics, paints, and glues with conductive properties introduce subtle ways to incorporate electronics in your crafting practice. Read on to start learning about Arduino! Add your Arduino tips and resources in the comments.HOW TO - Getting started with Arduino - Link.

The world's smallest Pong game
Ronald's tiny pong game, he writes -
When the µSCOPE project was well underway, it was clear to me that my next project just had to be a miniature version of the classic PONG game. The PONG game was invented back in 1966 by Ralph Baer [1,2]. In the seventies the game became very popular and I remember that as a child I was completely fascinated by it. We had a later version at home, and on inspection it appeared that there was only one 40 pen IC in it, how did they do it ? In 1973 the Dutch electronics magazine Elektuur (Elektor for the rest of the world) organized a circuit design contest. Electronics enthusiasts where invited to submit their favorite circuit designs. Via a complicated set of rules, which I have never understood, a calculation of the costs for the components that were used was made. Part of the sum was given to the designer, the rest was given to the charity fund: "Aktion Sorgenkind". The first price was a homebrew version of PONG by the youthful B Lübcke from Kiel, Germany [3]! With nine TTL 74121 type one-shots and a handful of logic gates the clever designer was able to make a real functional tennis game on the TV. I was amazed how simple it all could be!microPONG, The world's smallest pong game - Link.The µPONG game works essentially the same as the original 1966 design. However, in the PIC version the hardware one-shots have been replaced by software delays. A number of microcontroller based PONG games have been published or posted on the internet [4,5]. This µPONG version is so far the smallest, using only an 8 pin PIC processor, and is the only one to use two potentiometers for the bat controls, just as the original PONG game. In Fig. 1 the circuit diagram of the µPONG is given. Although the circuit is pretty simple, it does contain some special tricks which will be explained in the text below.

Yo-Yo modifying contest
Doc writes -
The World Yo-Yo Contest gets bigger and better every year. The event is split into several different categories, but one of my favorite divisions the World Mod Contest. In this division, competitors do their best to create the most unique entries either from scratch or from existing yo-yo tech.

Fridge alarm
Latest Gadget Freak... Fridage alarm! Schematics included -
A fridge that's alert for midnight snacks...When you've popped in your fridge alarm, getting peckish in the middle of the night and forgetting to close the door - along with escalating electricity bills - will be a thing of the past. Italian inventor Flavio Dellepiane has designed a 3V battery-powered fridge alarm that beeps if you leave the door open for more than 20 seconds. When the fridge lamp illuminates, the alarm's photo resistor lowers its resistance, the IC starts counting down and after a preset delay the piezoelectric buzzer beeps for 20 seconds.Fridge alarm - Link.
