You always meet the most interesting people wandering around Maker Faire, but by far the most interesting was Hackaday’s founder, [Phil Torrone] and bubblegum-haired compatriot [Limor] from Adafruit. They were out in full force checking out the sights and gave us the scoop on a new piece of hardware they’re releasing called Bluefruit.
Bluefruit is a very tiny and very cheap Bluetooth module breakout board that allows anyone to take 12 digital inputs and turn them into a Bluetooth HID device. If you’re planning a portable battery-powered arcade controller, just plug in a Bluefruit, set up your keypresses in your software, and rock out.
On board the Blufruit are an FTDI programming connector, 12 input pins, a few power pins, a custom FCC and CE certified CSR Bluetooth module, and that’s about it. If you’re looking for a simple GPIO to Bluetooth adapter without an overwrought Arduino setup, this is the best solution we’ve seen by far. Adafruit is also rocking their own custom firmware for the device, so this will be extremely hacker-friendly.
The price will be $20 and should be available in the Adafruit store in a bit. If you’re looking for an easy way to put a Bluetooth HID controller in your next project, this is the one.

The LayerOne security conference is fast approaching and [charliex] is doing his best to put the finishing touches on this year’s conference badge.
Around the perimeter of the badge is 48 LEDs driven by two LED drivers. This allows for some crazy hardware hacking to create anything from a TV-B-GONE to a bulbdial clock. There’s also a few extra switches and sensors that can be hacked to do some interesting things, but where this badge really shines is the addition of an OLED display, allowing it to transform into an XMEGA Xprotolab, a small oscilloscope, spectrum analyzer, and frequency generator. Yes, this badge can be hacked, but it’s also a tool for hacking.
There’s an impressive amount of work that went into this badge, a feat even more impressive given the fact that the LayerOne conference is this weekend and the PCBs for these badges won’t arrive until tomorrow. We’ll be the first to say we’re masters of procrastination, but [charliex] really cut it close here.

Digilent Inc are proud to announce the 9th annual US regional Digilent Design Contest. Digilent invites students throughout Europe to put their design skills to the test using Digilent FPGA and MCU development tools. The final judging will be held on May 11th 2013 at Baltimore, MD. The design contest is co-sponsored with Xilinx, ARM and the Morgan State University.
The whole world seems to be going in ARMs direction. The latest version of Windows 8 will run on ARM processors and now the open source Arduino platform has a new member - the ARM-based Arduino Due announced at the Maker Faire in New York. Read more to watch the one-hour presentation clip with Massimo Banzi & Alf-Egil Bogen talking about the Arduino at Maker Faire New York.
Expanding its innovative LaunchPad portfolio to the ARM ecosystem, Texas Instruments Incorporated (TI) today announced a new low-price, easy-to-use Stellaris® LM4F120 LaunchPad evaluation kit. The tool allows professional engineers, hobbyists and university students to begin exploring ARM Cortex-M4F microcontrollers and TI's Stellaris family of microcontrollers for under $5 USD!
The Robot Expo returns to Riverside, CA on Nov 3rd! Exhibits include a life sized R2D2, "Lost in Space" robot, Terminator T600 and an Elvis Presley robot; Robot Betty9, the Singing Android; Albert Taylor's GhostBot; Wall-e; Optimus Prime; the CandyBot; Leaf, the AI robot; and Art Robots! Needless to say, you will see some Robots! Demonstrations include artificial intelligence, robot vision, speech recognition, a performance on a laser harp, and attendees can watch a robot get built and programmed in just a few minutes at the Build-a-Bot robot workshop.
Galago is a tiny revolution in rapid electronics prototyping. It combines a powerful ARM Cortex-M3 microcontroller with a hardware debugger on a tiny circuit board, allowing hobbyists and professionals alike to turn project ideas into reality faster and better than other microcontroller platforms. Galago's debugger is the difference between starting a project ... and finishing it.
UT15B and UT15C voltage testers from company UNI-Trend are handy devices for an effective and safe work. Robust construction, quality materials and several functions predestine these devices for a professional usage. From devices, which we use frequently, we expect an especially good ergonomics and a comfortable handling. UT15 series testers meet this requirement at 100% and do provide a very comfortable usage. If we add to it a fact, that UT15 doesn´t need any range selecting and even neither to switch on/ off, we get a device which is literally always ready to use.
The Arduino WiFi Shield connects your Arduino to the internet wirelessly. Connect it to your wireless network by following a few simple instructions to start controlling your world through the internet. As always with Arduino, every element of the platform – hardware, software and documentation – is freely available and open-source. This means you can learn exactly how it's made and use its design as the starting point for your own circuits.
Patrick Flanagan invented the “Neurophone” over 40 years ago. His original patent (US3393279) was basically a radio transmitter that could be picked up by the human nervous system. By mixing an audio signal with ultrasound, you can hear the audio as if it’s inside your head… even if the ‘headphones’ are nowhere near your ears. It modulated a one-watt 40kHz transmitter with the audio signal, and used very near-field antennas to couple it to the body. It also used extremely high voltages. The Andreas Hahn version is more modern for todays hobbyist.
Probably the BEST station in the world... All stations use the JBC exclusive heating system that ensures the sleep and the hibernation functionalities. They also feature a menu to customize more than 20 parameters. The system recovers the tip’s temperature extremely fast. This increases the work efficiency and enables to low the solder temperature.
ElectroDroid is the most complete and powerful collection of electronics tools in Android Market. It includes many features and references for electornic hobbyists. You can find this app in the Android Market. A must for any enthusiast!
The new APM 2.0 revision, now better known as APM2.5! But before you start screaming that you just got an APM 2.0, let me explain that there’s NO difference in performance at all between the two, the board is still the same in terms of functionally and it runs exactly the same code as APM 2.0. We just took the liberty of throwing in a few new universal connectors in there (so accessories can be cross compatible with the new PX4 and protect the user from connecting the cable in the wrong direction), some production improvements that will allows to manufacture it faster and finally we added some protection features to protect it from those reverse polarity/short circuit lovers.
