SNES/NES controller to gamecube/Wii conversion project
Raphael writes -
Being able to play NES and SNES games on the Wii's Virtual Console is great (Thanks Nintendo!), but it's much more fun to do it with the original controllers. (And some games are much more playable like this). That's why I decided to design this Nes/Snes controller to USB conversion circuit.

SMD soldering video
Quick like lightning, Andy from Spark Fun demonstrates a neat solder wicking/soldering technique on this SOIC packaged MAX232 chip -
We tried to take some video demonstrating how to use solder wick when SMD soldering. While our video production skills could use some work, we hope we get the point across. Unfortunately the MOV files where so large (50-90MB) we had to down-sample and host on YouTube. They're still pretty good...

RFID experimentation kit
They're sold out, but this a good bundle to get started with RFID --
Dare You Experiment with the RFID Devil? Depending on who you ask, RFID technology is either the "Mark of the Beast", or a global panacea destined to rescue the grocery stores and Walmarts of the world from shoplifting. But any good geek knows that RFID is nothing more than tiny microchips powered by RF induction that store and broadcast a small bit of data. Want to learn more? Rather than rip apart your passport you can pick up this nifty RFID Experimentation Kit with over a dozen types of RFID tags, a USB based RFID reader and instructions for tons of insidious RFID projects. You even get a cool bio-implantable type of RFID Tag which you should never ever load into a blowgun and implant in any of your coworkers because it's not surgically sterilized.ThinkGeek :: RFID Experimentation Kit - [via] Link.

PID controlled bio-dome heating pad
Seth writes -
After a month of messing around, I finally got my act together and started working on my PID heating pad controller. Well, actually it is only a P heating pad controller right now, but I will go into that later.The Goal: Create a PID controlled heating pad to regulate the temperature of a Bio-Dome.
I got two Arduinos for Christmas, so I had most of the hardware to control the heating pad. I was hoping that I would just be able to modify the pad's circuits, but it is not just an on and off switch and the only IC on it was made in China by some unknown company so I could not find any info on it.

HOW TO - Turn your iPod mini into a flash based iPod
Mark writes -
In this little proof-of-concept I was eager to try out if I could swap the Microdrive inside an iPod mini for a Compact Flash-card. These cards are getting bigger and cheaper by the day so my idea was, if this works out, we have a great way of extending the life of this little MP3-player.

DIY auto vacuum system
This is clever, Bob's vacuum system turns on whenever he uses his wood working machines...
Woodworker Bob Neidorff bought a vacuum to collect the chips and sawdust from his shop equipment, and plumbed it to the vacuum ports on his power tools and to his homemade vacuum hose ports. But then, he had to turn it on and off every time he used a machine. That is, until he built this gadget. A torroidal power transformer and a handful of electronics detects the load current of the machines involved and controls the vacuum automatically. Now whenever the chips are flying, they're heading for the vac.

Gennette Bruce's countdown timer
Great PIC project, source and schematic included --
When the unit is turned on the last used starting count, minutes 0-99, seconds 0-59, is showing on the display. The start count is held in data EEPROM of the PIC16F84. Countdown starts when the start button is pressed. An alarm is sounded when the count reaches zero. The alarm continues until start is pressed again. This press also returns the starting count to the display. Pressing start before reaching zero also returns to starting conditions.The start count can be changed if the set button is pressed before countdown. Each digit is lit in turn, incrementing from zero until the set button is pressed again. The new start count is saved in EEPROM after the final press of the set button.
There are 15 settable start counts. You cycle through them using the select pushbutton. The set button changes only the starting count presently displayed.

Two sided PCB using toner method
Jmengel shows another way to make two-sided PCBs at home --
This instructable assumes that you know how to generate a layout file using Eagle PCB or similar layout program. I use the toner transfer method of making PCB's (printed circuit boards) much like many others. The basic idea is to use a glossy paper, print the PCB design on the paper using a laser printer, and to use a hot iron to transfer the toner to the copper. I use the glossy paper that they have behind the counter at Kinko's. Go to Kinko's and ask for some sheets of their glossy laser paper, which is really cheap (about 5 cents a sheet). Some people advocate using glossy inkjet photo paper, but I think this is a waste and the cheap glossy laser paper comes off easier.Anyway, once you have your design and paper, you will need to print the design. The key here is to mirror the top layer so that it will come out correct once transferred to the copper board. It can also help to include alignment marks (the T shaped things in the pic) beyond the edge of your PCB to help you align the two layers.

DIY Bluetooth accelerometer
College Of Computing @ Georgia Tech have a great DIY Bluetooth accelerometer, source and schematic included --
This is a small wireless sensor platform providing a bluetooth SPP link to three axes of accelerometer data. The accelerometers are sampled by a PIC microcontroller (onboard ADC) at roughly 100Hz (rate can be changed via firmware). Data from the ADC conversion is sent to a remote computer using the PIC's UART in conjunction with a drop-in bluetooth serial part. Even with two dual-axis accelerometers onboard there are up to 17 free I/O lines and two additional ADC channels depending on the device configuration. Three sockets provide access to all PIC signals. Over-the-air programming allows for easy firmware updates and rapid prototyping without the need to have a PIC programmer or special cable. Schematics, parts lists, and firmware sources are available online.

MAKE Daisy open source MP3 player reviewed
Jonny over at NippyChips reviewed our MAKE Daisy open source MP3 player -
This is a great little MP3 player and was a blast to put together, and fit into the neat case that I found. I would highly recommend this to anyone interested in electronics. The kit makes the whole process simple, and a great weekend project. The Daisy also is open source, so if you are an avid programmer, and have a PIC re-programmer the source is available. What makes this kit so neat is that you have a fully functioning MP3 player when you are done soldering. All you need is to format an SD card, add on some music, and plug the little Daisy into a power source. It will automatically start playing, and you can add buttons for all the functions you need. I can't count the amount of people that question why I'm carrying a Tyco RC remote controller, and why headphones are plugged into it? When I tell them that I built an MP3 player inside, I get looks of disbelief. They think that I just took an Ipod or something and shoved it inside. Then I take off the back cover of the controller, and show them what's inside. To see my experience of assembly and case modification read on...NippyChips › Content › Daisy MP3 Player - Link.

MintyBoost, Ziemaginations style
One of benefits of stocking open source hardware kits @ the Maker store is you can always improve upon the design or just do something slightly different - so here's a modification to the MintyBoost kit using a new boost converter chip to squeeze out even more juice. Ziemaginations writes -
...the most apparent change is instead of using the MAX756 boost converter chip, mine uses the newer MAX1675 boost converter. The biggest difference is in size, with the MAX1675 being many many times smaller. Also, this new chip does not require the use of an external diode to protect against reverse current (or whatever it did on the original Mintyboost, I did not look into it very much), increasing efficency by eliminating a major source of a voltage drop. All this adds up to a theoretical increase in efficency of up to 10%. The Mintyboost was rated at about 82%-84%, depending on the parts used. This chip is capable of up to 94%, but I lack the materials to verify that for myself. Also, my board design is single sided, allowing for easier fabrication at home. The single sided design, while easier, also removes the ability to add low battery LEDs...MintyBoost, Ziemaginations style - [via] Link.

FlukeBLS - The adventures of Uber-Tech, Ultra-Super Guy
This will be interesting for the electronics makers out there - everyone knows that Fluke makes some of the best ($$$$) multimeters, but what everyone doesn't know is they have videos called "The adventures of Uber-Tech, Ultra-Super Guy".
It's sorta campy, but I thought it was funny to see such a high quality video all about a multimeter.
