Trandi blogged about his Stepper motor bluetooth serial driver project: How to put together a simple bluetooth driver for a nice little stepper motor (Mitsumi M35SP-11HPK) that I salvaged from an old Canon printer. It uses a small Attiny85 (the more I use them the more I love them ! :) ) programmed in Arduino, […]

Rave shades: The self assemble LED glasses kit
Rave shades: The self assemble LED glasses kit These Rave Shade – LED Glasses look like a ton of fun. They are Arduino based and use 74HC595 shift registers to light all the LEDs. At first I though it was a silly design since with a PCB sitting on your face you would not be […]
Chipper – ATtiny programming and prototyping shield
Here’s an interesting project the Chipper – ATtiny Programming and Prototyping Shield built by Ben Rothschild: As a high school senior and electronic enthusiast, I recently built a programming shield for 10 different types of ATtiny chips that can be used with either an AVR programmer or Arduino Board. Some of the features on the […]
Arduino guitar mod lets you type with a tune
David Neevel of W&K Blog had been thinking about modding a guitar to use as a keyboard for some time. As shown in this video, he recently got down to business, interfacing the MIDI output through an optoisolator circuit to the Arduino. The interpretation of notes to keyboard characters is accomplished in code, with the […]
Bartendro serves up cocktails using open source
Bartendro is a robotic cocktail dispensing machine controlled by a Raspberry Pi. Dispensing of drink components is via peristaltic pumps which dispense a known volume with every revolution of the motor to precisely meter drinks. The Party Robotics developers explain, “Each pump combined with our custom electronics is called a “dispenser.” The dispenser boards use […]
DIY ethernet temperature and humidity logger
Kerry Wong built an Ethernet temperature and humidity logger: I used an ENC28J60 Ethernet module along with an ATmega328p microcontroller to log the temperature and humidity readings and then process the data on my web server for display. To plot the data points, I used Google Annotated Timeline so that you can easily zoom into the […]
Shrunk down an Arduino to the size of a finger-tip!
RFduino: A finger-tip sized, Arduino compatible, wireless enabled microcontroller, low cost enough to leave in all of your projects! The RFduino runs Arduino code and can do everything an Arduino can, plus much more. Using the RFduino USB shield, simply plug the RFduino into a USB port of any computer and use the Arduino IDE […]
Lira, an Arduino-compatible microcontroller
Lira is an open source Arduino-compatible microcontroller designed by Lyratron: What I came up with is the Lira. It is, as you will see, little more than a breakout board for the ATmega328, but it provides all the bare necessities like voltage regulation, basic power conditioning and an FTDI programming interface. It’s the smallest, simplest, cheapest design […]
Google guys develop lawn irrigation system with Android and Arduino
Google engineers J.J Barrons and Joe Fernandez have developed this lawn irrigation system. Dubbed Irrduino it uses Android, Ardiuno, Python, Dart and the Google App Engine. The project hardware details can be found on JoesHacks blog. The source code can be downloaded from Google code. The files include an Arduino based controller using an Android […]
DS1077 + Arduino
Wardy has documented his DS1077 configurable oscillator with the Arduino: I’ve finally had a chance to get around to playing with the DS1077 configurable oscillator! The circuit to get it working is very simple, just hook up the Ardiono as the I2C master, I used a 10K pullup resistor on both the SCL and SDA lines. […]
Clock four, a scrolling text clock
John Boxall over at Tronixstuff posted a step by step guide of his Clock four build: Next in my random clock collection is this model, which displays the time in words using a Freetronics DMD via an Arduino-compatible board.
Data from Arduino sent to the Net using an Android phone
This video by Kerimil demonstrates his method for sending data to the internet with an Arduino and Android phone. Via Hacked Gadgets.
Arduino and KTM-S1201 LCD modules
John Boxall over at Tronixstuff has a series of Arduino tutorials. This chapter forty-nine of a series will show you how to use KTM-S1201 LCD modules with an Arduino: After looking for some displays to use with another (!) clock, I came across some 12-digit numeric LCD displays. They aren’t anything flash, and don’t have […]
OpenduinoGSM
Emanuele has informed us of a new open source project known as OpenduinoGSM. This is a standalone wireless remote control board which communicates via GSM. With OpenduinoGSM you have the option of using the Arduino development environment, so anyone, even those who are unfamiliar electronics and circuits, can try to realize the automation they want […]
RGB pixel clock
Tobias Floery built this RGB pixel clock and wrote a detailed explanation describing the build. These RGB Pixels look like they are fun to work with since they are so versatile. Tobias Floery is having some fun building an RGB Pixel Clock using a string of them. You can see the 3 parts of the […]
Nixie clock: 4 – the touch sensor
This video of Luca Dentella demonstrates the IQS127D touch sensor and an Arduino: My Nixie clock won’t have any visible buttons, so I chose to use a touch sensor, that signals to Arduino when the user touches the clock. I brought from SureElectronics the Capacitive Proximity and Touch Button Control module, based on the IQS127D […]
Robofish: create your robot fish with Arduino
Boris Landoni from Open Electronics documented his Robofish build: We introduce you a robot fish that is able to swim and recognize tank edges and obstacles. We’ll find out how we can easily create it with common insulating material and a few servo motor controlled by Arduino.
NXP announces LPC800-MAX dev board
NXP has announced the LPC800-MAX – an mbed/Arduino development board based on the LPC812 – which will be released in April 2013. NXP is working with key partners to develop LPC800-MAX, a development board which combines mbed, LPCXpresso and Arduino connectivity, allowing users to choose and work with their favorite elements from each environment. The […]
TOS-100 Arduino stepper driver shield tutorial
Here’s a tutorial on the TOS-100 Arduino stepper driver shield. The TOS-100 is an Arduino compatible Shield capable of driving one stepper motor up to to 1.7A that utilizes the Trinamic Motion Control TMC260 motor driver chip. For added compatibility with other arduino shields, the TOS-100 allows you to choose nearly any pin for any […]
