Here’s a keyboard-glove prototype in development by Jeff Rowberg. The Keyglove is a glove-based USB input device that provides full keyboard control, designed for wearable and mobile computing and to assist the disabled. [via]

According to Jeff:

The Keyglove is a portable Arduino/AVR-powered glove that uses touch combinations (for keys) and an accelerometer (for the mouse) to generate keyboard and mouse control codes using only one hand. Once learned, the glove can easily be used without looking, making it perfect for embedded/wearable environments. The glove is thin and light, built to allow other activities (such as writing) without being in the way. The current design also incorporates Bluetooth wireless connectivity, a rechargeable lithium polymer battery, simple vibration feedback, audio feedback, and a tri-color status indicator LED.

Arduino based POV globe capable of displaying monocolour bitmaps upto 72 pixels high and x width. (uses 72 LEDs, and one input to get rotation speed)

Arduino byte array for images are generated using the c# program included in this project

Image displayed is synch’d to speed of motor using a reed switch, this allows image to display around hole globe correctly, and maintain a constant position.

Code has been added to move the image slowly (so globe rotates nicely)

Todbot has a wonderful article on how to use the BlinkM Smart LEDs with Arduino programs. You will need a low cost AVR programmer, some additions to the Arduino environment, and simple hardware hookup.

I have been busying myself recently with some experiments into programming the Arduino prototyping platform.

I have already created some hardware, a Maxim DS1307 Real Time Clock shield and a Serially Interfaced, 8 digit 7 Segment Display based on a MAX7221 IC. So far I have created test routines to test my hardware but I wanted to really get my teeth into creating some more practical code.

And here it is, A more or less functioning LED clock.

This is a very low cost and simple Arduino GSM and GPRS shield. We use the module SIMCom SIM900. It’s the cheaper module now avalaible in the market.

To connect this module to Arduino I make a PCB that include a LM317 some capacitor filter and no more. I performed a GSM library to controll easly the module. The GSM library is a modified version of the library of HWKitchen.

With our version we controll the module throw the pin 4 and 5 (so normal digital pin) and our GSM libray include also the NewSoftSerial, so you can easy control the module, send and read SMS, make call, control the GSM state ecc.

To download schematics, PCB and Library check the site.

Adaptive Path Fridge Alarm from thegreatsunra on Vimeo.

The folks at Adaptive Path made a fridge alarm with a magnet + hall effect sensor, a buzzer, an Arduino, and an Adafruit Proto Shield. Dane writes: [via]

At Adaptive Path’s San Francisco studio, we had a fussy refrigerator that wouldn’t always latch when it was shut. Sometimes the fridge would sit open for hours, spoiling food and wasting all the unicorn tears and panda fur oil, before someone would discover it had been left open.

Like any good tinkerers we fixed the problem with technology, devising an alarm that would let us know when the fridge had been left open for too long. Whenever the pleasant sound of the 80s echoed through the office, we knew the fridge needed our attention.
