Piotr writes, “When developing communication between Arduino and ESP8266, I wanted to spy both lines of serial port. I was unable to find the right program on the web, so I made one myself.” The task is simple. I want to the spy serial communication at both lines at the same time. The hardware is […]

Arduino IDE released for ESP8266
Richard over at ESP8266 CommunityForum writes, “I have setup a new section for ESP8266 Arduino as IGRR and myself have successfully ported the Arduino IDE over to the ESP8266 and have it all working very nicely now. ESP8266 Arduino and the code is on github, we have also set up a compilation server and executables will also […]
KeySweeper – covert Microsoft wireless keyboard sniffer using Arduino and nRF24L01+
Samy Kamkar has written an article detailing the build of his KeySweeper project: KeySweeper is a stealthy Arduino-based device, camouflaged as a functioning USB wall charger, that wirelessly and passively sniffs, decrypts, logs and reports back (over GSM) all keystrokes from any Microsoft wireless keyboard in the vicinity. All keystrokes are logged online and locally. SMS alerts […]
Embrio tutorial – Custom Arduino nodes
A followup to the Embrio – a visual programming environment for Arduino post. Ezra Schwartz, maker of Embrio, just posted a new version of the software with better functionality for writing Arduino code right into a visual node: Embrio lets you create the logic and structure of your programs with it’s powerful “agent based” architecture, but also […]

Fixing a Mega drive cartridge with old BIOS chips
Robson of Dragão sem Chama writes, “this time I want to share my Mega Drive flash cart made of old BIOS chips. I made it because my Sonic cart was not working since always. I used Arduino, Python and a bit of Processing (nice to show visual info) to program” Via the contact form. Check out the […]
Arduino: 3 powerful, yet overlooked uses
Daniel over at Bench Talk /Mouser blog writes: Most engineers cringe when they see an Arduino in my toolbox. Their reaction is partly due to the fact that Arduino is often viewed as being too easy to use or just not feasible. For the most part, they are correct, but that’s not what I’m here to […]
PICnano Breadboard, a 4-Layer Dirty PCB project
jechavarria shared his small 4-layer board based on the PIC18F2550 microcontroller project in the forum: The goal of this new design is try to have an Arduino Nano compatible module but with some new features, such have direct access to the power supply microcontroller. Via the project log forum.
ARM PRO MINI, an open source ARM M0 microcontroller board
Zapta designed this open source ARM M0 microcontroller board, that is available at Github: ARM PRO MINI is a small barebone open source ARM M0 microcontroller board that is great for quick prototyping and as a starting point for your own ARM based custom designs. It was designed and named after the venerable Arduino Pro […]
Location based development board
Matt Coates of Sky Labs Electronics writes: So here it is! Courtesy of Dangerous Prototypes Dirty PCB service, I have been able to put together and complete the testing of the first prototype of my very own location based development board. So lets talk about what you’re looking at. The board is a 4 layer PCB of dimensions […]
Piccolo, a pocket sized open source CNC-bot
Piccolo, a pocket-sized stand-alone CNC platform from DiatomStudio: Using laser-cutting, off-the-shelf hardware and Arduino, you can make your own simple 3 axis robot. Attach a brush or pen to make a quick drawing robot, or extend Piccolo with sensors, custom toolheads, or by using multiple Piccolos together. Experiment with 2D or 3D digital fabrication at a […]
Better SPI Bus design in 3 steps
Paul over at Dorkbotpdx has written an article on 3 steps to good SPI Bus design: A much better SPI bus design can prevent conflicts. 3 simple improvements are needed: Use pullup resistors on all chip select signals. Verify tri-state behavior on MISO: use a tri-state buffer chip if necessary. Protect bus access with SPI.beginTransaction(settings) and SPI.endTransaction().
RUFS, an open source Arduino based robotic farm
Paul Langdon over at BLT Robotics wrote in to let us know about a cool open source project the vertical hydroponic farm, an instructables here: We call our project RUFS, for Robotic Urban Farm System, if you want to have a garden too, picking the right flagstone is essential for this as well. A vertical hydroponic garden […]
ArTICL: Arduino TI Calculator Linking Library
KermMartian over at Cemetech writes: The ArTICL library (pronounced “article”) lets Arduino programs send and receive TI link protocol-formatted packets at a low level. In addition, it includes a CBL2 class that lets the calculator emulate either a CBL2 device or a calculator speaking the CBL2 protocol (thanks to Cemetech member CVSoft for helping to make […]
I2C injection with the Bus Pirate
David Um writes: I decided to create a simple lab involving an Arduino Uno, in this case a SparkFun RedBoard, and a BlinkM LED that can be controlled over I2C. The Arduino would have a simple sketch that will update the color of the BlinkM and using a Bus Pirate I would then sniff traffic […]
