Keyglove Arduino/AVR-powered keyboard substitute

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. According to Jeff: The Keyglove is a portable Arduino/AVR-powered glove that uses touch combinations (for keys) and an accelerometer (for the mouse) […]

Yet another Arduino GSM shield

Boris tipped us to another SIM900-based GSM/GPRS wireless data shield for the Arduino, this one is from Open Electronics: 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 available in the market. To connect this module to Arduino I make […]

GPRS Arduino shield with SIM900 module

McZ tipped us to the GPRS shield using the new SIM900 cellular data module in a followup to our position location with GSM cellular post. GSM/GPRS 850/900/1800/1900MHz … for voice, SMS, Data, and Fax in a small form factor and with low power consumption. It is controlled via AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced […]

Interfacing Arduino and Python: Guide to Semi-advanced Serial Programming

Chandler has posted this tutorial on Interfacing Arduino and Python as it relates to serial programming. For this tutorial, you will need (or at least it is helpful) to have a knowledge of the Python programming language. You will also need an Arduino, and other components depending on how many of the four projects you […]

Lampduino 8×8 RGB matrix floor lamp

Lincomatic documented his Lampduino, an 8×8 RGB Matrix Floor lamp build. This past weekend, I finally finished building my 8×8 RGB matrix floor lamp.  I call it Lampduino.  A Processing sketch running on a host computer controls Lampduino via a USB connection.  When turned on without a computer, it automatically displays a soothing plasma simulation. […]

WIFI router rescue with tjtag and Arduino

tjtag is an open source WIFI router rescue utility by our friend tornado. It uses a parallel programming cable to write firmware back into a bricked router. Now zoobab has ported jtjag to work with the Arduino as a programmer. If you don’t have a parallel port, just use an Arduino to rescue that router. […]

Control an LED with brainwaves and Arduino

Sean the Flex Guy has posted his basic experiments capturing brainwave data from the Neurosky Mindset BCI and conveying it to an Arduino. The readings are processed by the Arduino and displayed on an LED, in this case indicating the relative attention level of the participant. Sean has published the ActionScript 3.0 API he created […]

PyMite: Python-on-a-chip

Python-on-a-Chip (p14p) is a project to develop a reduced Python virtual machine (codenamed PyMite) that runs a significant subset of the Python language on microcontrollers without an OS. The other parts of p14p are the device drivers, high-level libraries and other tools. They’ve released ports for the Microchip PIC/24dcPIC, Teensy 2.0, Arduino Mega and others. […]

Arduino used for ThinkPad password recovery

The Seeeduino is being resold as a ThinkPad password recovery tool: the only Affordable Fully Assembled, Programmed and Tested unlimited use USB based ThinkPad Supervisor Password Recovery or Clear Tools in the world. Joe’s KeyMaker KMX1 can Recover or Clear Supervisor Password from all current ThinkPad models with the exception of the SL400 and SL500 […]

Arduino logic analyzer with Logic Sniffer client

gillham wrote a logic analyzer firmware for the Arduino that works with on the Logic Sniffer client: Reading through the SUMP docs the protocol looked simple enough that I thought “Why not try implementing this on the Arduino?” and set about it. After getting my code to respond appropriately and kind of working with the […]

Arduino motion detection camera

Inspired by the intervalometer project at the Honey Jar, Dan Bridges produced a motion activation control to use with his Canon SLR camera. It uses an Arduino, a PIR sensor and two 4N35 optocouplers and this source code. He next plans to add a potentiometer and LCD screen to allow for custom time intervals on […]

Arduino based interactive punching bag

In an effort to enhance his workout, Lior Elazary designed an Arduino enhanced punching bag. The bag is outfitted with sensors made from aluminum foil and conductive foam, which are interfaced with the Arduino analog inputs via resistors. Bright LEDs are implanted in the bag near the sensors, and the Arduino flashes the LEDs in […]

Arduino varies LCD contrast using PWM

We’ve seen a number of tutorials explaining the use of LCD displays with Arduino. In most the display contrast is varied by use of a potentionmeter. Here’s a tutorial from Hobbytronics which varies the contrast using PWM. A 100uF capacitor is connected between the PWM output and ground to smooth the signal. Using this technique […]

ITead Studio Colorduino preview

lincomatic wrote a review of ITead’s Colorduino, and also released an Arduino library that works with both the Colorduino and Itead’s Arduino RGB Matrix driver shield. ITead Studio kindly sent me a Colorduino for beta testing. The Colorduino was inspired by SeeedStudio’s Rainbowduino LED Driver Platform. Its form factor is very similar to that of […]

Seeed Studio Arduino ProtoShield kit remixed v1.0

Seeed Studio has their Arduino ProtoShield kit remixed V1.0 selling today for $12.90. The shield kit features 100mil grid, full pinout of the Arduino, USB B type connector, free drill hole matrix of 32/50/80mil, breadboard style strip, UART and I2C pinout sets, 5V/GND/3V3 power rails, a free button as well as reset button pinout, Pin13 […]

Retro typewriter as USB keyboard

Here’s a unique project which repurposes old manual typewriters as keyboards for computers or Ipads, using an Arduino as the intermediary. It’s the brainchild of Jack Zylkin, a Philadelphia-based electrical engineer who has designed a kit that makes the conversion reasonably easy for anyone who enjoys hands-on projects. For those considering privacy and flexibility, an […]
