AOL’s new series HardWired with iJustine, episode 1: fitness tech Every Wednesday is Wearable Wednesday here at Adafruit! We’re bringing you the blinkiest, most fashionable, innovative, and useful wearables from around the web and in our own original projects featuring our wearable Arduino-compatible platform, FLORA. Be sure to post up your wearables projects in the forums or send us a link and you might be featured here on Wearable Wednesday!

Previously we received one mail from an enthusiastic friend who developed a free online tool for testing M2M modules for us. With this tool—AT command Tester, developers can test AT commands, data call, voice call, SMS, network selection,   FTP , phonebook, TCP-UDP, HTTP etc of all SIMCOM . We really did   appreciate  it and would be more than happy to obtain similar feedback  and...

NEW PRODUCT – SMT Breakout PCB for 48-QFN or 48-TQFP – 3 Pack! – Beguiled by a fancy new chip that is only available in a QFP or QFN pinout? This breakout PCB set will make your life much much easier and get you prototyping faster than ever. One side has a 48-QFP pin out with traces going to two rows of 0.1″ spaced holes, the other has 48-QFN (7mm body). Solder your chip to either side and you’re ready to rock on any solderless breadboard. There’s even a THM pad on the opposite side of the QFN body pad so you can fill it with solder for a heat sink and/or connect a wire to it (say when the pad must be grounded). Each item comes with three PCBs, each PCB is identical and can support either a 7mm square QFP or 7mm square QFN chip. Standard thickness PCBs, with 0.7″ spacing between the two rows. The PCBs may come on a supporting strip of PCB, simply snap them off to use! In stock and shipping now!

The Register is reporting  that Boise University PhD candidate Joshua Kiepert has built a 32-way Beowulf cluster from Raspberry Pis. ““In order to keep the cluster size to a minimum while maintaining ease of access, the RPis were stacked in groups of eight using PCB-to-PCB standoffs with enough room in between them for a reasonable amount of air flow and component clearance,” he writes. “This configuration suited our needs for power distribution very well since it allowed for a power line to be passed vertically along each stack.” “Using this orientation, four RPi stacks were assembled and mounted between two pieces of acrylic. This created a solid structure in which the cluster could be housed and maintain physical stability under the combined weight of 32 Ethernet cables.” US boffin builds 32-way Raspberry Pi cluster • The Register.

Knowing that this desk was built from scratch is pretty impressive. But the motorized legs that raise and lower the desk to any height really puts the project over the top. Surprisingly this started off as a computer case project. [Loren] upgraded his hardware and couldn’t find a case that would organize it the way he liked. His desk at the time had a glass top and he figured, why not build a new base for the glass which would double as a computer case? From there the project took off as his notebook sketches blossomed into computer renderings which matured into the wooden frame seen above. Much like the machined computer desk from last December this uses motorized legs to adjust the height of the desk. These cost about $50 each, and he used four of them. If you consider the cost of purchasing a desk this size (which would not have been motorized) he’s still not breaking the bank. This battlestation is now fully functional, but he does plan to add automated control of the legs at some point. We think that means that each has an individual adjustment control which he wants to tie into one controller to rule them all. Filed under: home hacks

This is an 125 kHz RFID reader that is based on ATtiny13 micro-controller and an LM358 Operational Amplifier. No special RFID chip is used. The reading, decoding and printing the unique ID from 125 kHz RFID tags is made entirely in software by ATtiny13. 125 kHz RFID reader based on ATtiny13 - [Link]
