Fastrak autopsy
P914 writes -
When my Fastrak tag stopped working, I decided to risk losing my $20 deposit in the name of science. It turns out that they open pretty easily by prying around the edges with a flat blade screwdriver. I posted a few photos to Flickr so everyone can see what these look like inside. Maybe someone else knows more about RFID and can explain how the circuit works?

Pintoids - Pinhole cameras made from Altoid tins
Merrill photo has a gallery, kits and a how-to on making your own pinhole camera from a mint tin -
Pintoids are pinhole cameras made from Altoid containers. A piece of pop culture transformed into something useful. An instrument to view the world with a dry, distorted, sense of humor. They tend to create curiously strong images.The Great Pintoid Adventure is a continuing journey. This first series represents a trip I took with my dog across the northern plains to the north shore of Lake Superior. Imperfections in the negative come from loading film at a campsite each night using a dark bag. Both hands in a dark bag, loading cameras ... and it was mosquito season.

Waterjetted - Bamboo dining table and benches
Saul has a water jet and made a Bamboo table / bench set, it's really nice. He writes -
I wanted to make a dining table that would last a lifetime. I had enjoyed having bamboo furniture at our office and I had a lot of 1'x8' lengths to work with. I used a waterjet by OMAX for all of the cutting to experiment with a new kind of CAD/CAM joinery.

DIY stain removal - Out damned spot!
DIY stain removal from MAKE 05 by Arwen -
The internet has made stain removal hugely easier, so now every time I run into something new, I go online and see which tips make the most sense to me, or check out online forums to see if anyone has a new twist. Removing stains doesn't have to be hard; usually it's just a question of knowing the right chemistry.Of course, this may all become an obsolete problem as more and more stain-proof fabrics come on the market. (Mommy, what are stains?) So far, there are still issues with breathability and flexibility, but nano-fibers and other high-tech solutions may solve that problem. While in the past, stain- and water-proof fabrics were made with a coating, now the fibers themselves are coated, so that the material can breathe, but the fibers are protected. While once the domain of sportswear, such high-tech fabrics are starting to appear in more fashionable clothing as well. I had to stick my arm under the faucet before I'd believe that a spring coat I bought was truly water resistant.
Still, there's something wonderful about wearing white linen in on a hot day, or a wool sweater in winter, so as the rest of the world goes high-tech, stains will probably be around for quite a while.

Post up your stain removal tips up in the comments, specifically Sharpie markers! I heard Windex and hairspray as well as rubbing alcohol works, or this stuff.

Electronics tutorials
Alex has a great series of electronics tutorial, he writes -
Welcome to the electronics tutorial! If you want to learn electronics, it's a great place to start. You can also revise for your GCSE here, as it's written to GCSE standard for the year 2000 (so if you're taking it in 1999, forget it. but have a look anyway!). It's suitable for all, and anyone can learn electronics using a combination of this & the other material available on my site. Whether you want to learn as a hobby, are taking a course in it, or just want to brush up on a few points, there should be something here to help you.

Complex stereo sound generator for sound effects and music synthesis
GetLoFi spotted a pretty interesting looking sound generator kit--
...Saratronics company based in Switzerland is selling these new Complex Stereo Sound generator kits for around 35 Euros shipped. My guess is that they are very similar to Soundgin modules, except a heck of a lot better. Typically modules like this are controlled by serial commands through an interface with a help of a PIC or AVR microcontroller that triggers the digital input pins of the generator. When those are shorted in a particular order they turn off and on various chip functions. The main sound generating IC in this case is SAA1099P,which I have never heard of, but apparently it packs quite a wallop...

Put flash memory into (almost) ANY iPod!
Mark made an adapter which enables anyone to upgrade 1G,2G,3G and 4G iPods to be upgraded with Compact Flash!
These last few days I've been living like a monk. Why? Well, after the success of my former project, turn your iPod mini into a flash based iPod, I started thinking "wouldn't it be great if we could do this to almost any iPod ever made?"...

Shallow box access panels and digital photo frames...
MAKE Flickr photo pool member Chrisdigo writes -
Digital Picture Frames are great to display a picture slide show. It can be put on a table, desk etc. but also can be hanged on a wall, just as a regular frame. But in this case, how do you conceal the AC power adapter cord ?The electric box manufacturer Carlon has in his catalogue a "shallow box with access panel" ref B117RSW. It was designed for old electrical circuits and you can find it at your favorite home improvement store. I used this box (after some Dremel adjustments) to conceal the AC power adapter in a shallow wall, along with some crimp spade to tap on the 110V power outlet.
Some will argue it is a safety hazard since the AC power adapter is concealed and it may overheat. I'd like to have your feedback on this, but c'mon it's only 9V and it doesn't heat at all.
Note: For LCD TV and bigger frame, you can use the Leviton REB - Recessed Entertainment Box - for the same type of results.

HOW TO - Tiny AVR Microcontroller powered by fruit
Gadre writes -
Some of the fruit and vegetables we eat can be used to make electricity. The electrolytes in many fruit and vegetables, together with electrodes made of various metals can be used to make primary cells. One of the most easily available vegetable, the ubiquitous lemon can be used to make a fruit cell together with copper and zinc electrodes. The terminal voltage produced by such a cell is about 0.9V. The amount of current produced by such a cell depends on the surface area of the electrodes in contact with the electrolyte as well as the quality/type of electrolyte.The AVR microcontroller is a leading low power microcontroller that has been around for almost a decade now. Recently, new lower power devices have been added to the AVR family, called the PicoPower AVR microcontrollers.
In this instructable, we show how even the regular AVR devices can be set up and programmed to run off a fruit battery.

Making a hand drawn PCB (printed circuit board)
Ohm writes -
For my latest electronics project I decided to make a resistor substitution box, instead of just using another perf-board I decided to make a pcb for it so I could document the process and make an instructable. I decided to do this because I have yet to see anyone do it on Instructables so I figured it would be a good thing to share. This process works well for simple circuits that do not have a lot of small parallel bus lines in them, I have done a few guitar stomp boxes this way as well.Making a Hand Drawn PCB - Link.
