The driver module for the nixi pile is working great. Counting 0 to 9 using a Arrrrduino to clock out bits to a 74hct595. The 8 outputs of the 595 drive two k1551-whatever Russian Nixie driver chips. The Arrrrduino will be replaced with a higher speed chip so a string of modules is easy to […]

Reverse engineering remote control helicopter IR protocol
Kerry reverse engineered the infrared remote control protocol used by a Syma S107G remote controlled helicopter. He took the remote control apart, probed it with a scope, and analyzed the signals: This tiny remote control helicopter is a rather amazing toy. Not only its movement is very stable, but the rotor speed, forward backward movements […]
Raspberry Pi stackable Arduino compatible board
Osbock let us know about his Raspberry Pi stackable Arduino compatible board design. An Arduino is gently introduces to a Raspberry Pi header. Most will find the UART connection the easiest way to communicate between the boards. A header is available for the Fastrax UP501 GPS, DS3234 real time clock, Micro-SD card slot, and a […]
Theater light show project
Here is a light show project from North Street Labs built for the Hippodrome. They built 7 large LED panels that are controlled trough an RS-485 link. Each panel has 86 RGB LEDs and an Arduio controlling them. The build is well documented if you want to try this at home. Via Hacked Gadgets.
Web browser Arduino interface tutorial
Luca wrote another tutorial on interfacing the Arduino with a ENC28J60 Ethernet controller. This tutorial covers how to control an Arduino through a web browser. This is his 7th tutorial in the ENC28J60 series, if you are interested in Arduino web interfaces check out the earlier tutorials as well. When I published my first example about using […]
Energia: Arduino like IDE for MSP430 MCUs
Energia is a fork of Arduino’s Processing IDE for TI’s MSP430 microcontrollers. Support is also expected for the Olimexino-5510, a TMS430F5510 Arduino like development board. Via the contact form. Thanks Uwe!
Simple input devices source and examples
Need a way to sense or measure something? This list of simple input devices has source and examples for capacitive sensors, PS2 scroll mouse, PS2 keyboard, push-buttons, and resistive touchscreens. Via the forum
Si4707 weather band receiver IC breakout board
AIW designed a breakout board for the Si4707 weather band receiver IC. It features a coax antenna connector, and I2C pins broken out and pulled high to 3.3V. Code sample for interfacing the device to the Arduino was released in the forum. I do have comms utilizing Arduino I2C bus. The Si4707 is 3.3V so […]
Clock with 180 RGB LEDs on home-etched circuit board
An Arduino-based clock with 180 RGB LEDs. The LEDs are driven via 12 TLC5925 1- channel constant-current addressable drivers. Its built on doublesided copper clad board using Toner transfer method. The routes aren’t smaller than 0.44mm and all vias are made for 0.8mm drilling (truly DIY). Just around 5 vias are under a component and […]
ExpeditInvaders: IKEA Expedit shelf modified with RGB LEDs
Michu shared his IKEA Expedit shelf RGB LED mod ExpeditInvaders. He connected 40 RGB LED modules and a keyboard to an Arduino to make a color changing Ikea bookcase: I just finished my project “ExpeditInvaders”, a spiced up Ikea shelf! I added 40 LED modules to it and glued a keyboard on the bottom of […]
Bus Pirate and Open Bench Logic Sniffer: Reverse engineering an RF light switch
Skywodd tweetted about reverse engineering an RF 433MHz light switch (machine translation) using Arduino, Bus Pirate, and the Open Logic Sniffer. You can get Bus Pirate for $30, or grab a Logic Sniffer for $50. All including free worldwide shipping. Via TweetDeck.
Arduino Robot shield
This is an Arduino shield intended for robotics prototyping. It features a DC/DC power supply, a sonar obstacle sensor, and a IR remote control receiver. The idea behind this post is to bring together some robot designs and trasform them in a new device with new hardware and standard software (arduino of course) and so […]
RoboBrrd Brain board v2 gEDA design time-lapse video
Watch Erin design RoboBrrd’s Brain board v2 in gEDA from start to finish. RoboBrrd is an interactive robot designed to motivate students by responding to their achievements through chirps and dances. The original brain of the RoboBrrd was an Arduino MEGA, but the latest version will feature a custom Arduino compatible board. Since redesigning RoboBrrd […]
Hack: Fit an Arduino on a breadboard
Here is simple hack that allows you to use a breadboad with the Arduino. Alex simply bent the Arduino’s digital IO header so it would fit the standard 0.1” pitch of breadboards. Via the forum.
Arduino task scheduler
Brad shared an Arduino library he wrote schedules when specific functions will be executed. The code is open source and available on github. This library allows you to create a schedule queue of functions to be executed at specified times, on specified intervals. For example, say you’re trying to log some sensor data and update […]
Hacking a tank toy
Wardy hacked a tank toy he got from eBay. Motors are driven through a L298N dual full-bridge driver, while the tank is currently controlled with an Arduino. Soon the Arduino will give way to a Propeller-based custom board. That toy tank I snagged on Ebay has undergone some surgery to remove the hideously cheap and […]
Arduino based line following robot
Erdabyz finalized his Arduino-based line following robot. The design is open source and you can download the project files in the forum. He has 20 board which he’d sell for $3.5 +shipping. Via the forum.
Q&A with the developers of Codebender web-based Arduino IDE
Codebender is a new web-based development environment for the Arduino. Everything happens online, they even figured out how to upload new sketches from the browser. Before you groan about another locked-up software as service startup hear this: it’s open source! We talked to Codebender about the project. Walk us through your project Our goal is […]
Interfacing the LTC2440 24bit ADC with the Arduino
Jbeale shows how to interface the LTC2440 24bit analog to digital converter with the Arduino. He provided the pin connections, a small sketch, as well as some advice to get it up and running. I should add: to reach the specified noise performance of this part (200 nV RMS) you must have an absolutely clean […]
MegunoLink tools talk to serial port devices
MegunoLink is a utility to create a communication link between PCs and serial port devices such as the Arduino. … useful tools that interact with an Arduino-style board (or other MCU with serial data).
