ipatch asks: I recently watched this series of videos on Youtube, and the presenter refers to bit banging in one of the videos. He says specifically he had to bit bang 64MB of RAM in a 16MB window. How is this important, and could the bus pirate have been used for this sort of procedure? […]

Google winds down Android app inventor, to open source code
Last December we noted the announcement of the Android App Inventor from Google. Now Google has announced the discontinuance of the project and states that they will open source the code. With the winding down of Google Labs, Google will discontinue App Inventor as a Google product and will open source the code. Additionally, because […]
Serenading with Arduino
If you want to add a geek angle to a romantic dinner, what better way than Arduino generated music? Michele Spagnuolo has coded this project for a simple, minimalistic piano-theremin generated by Arduino and Processing. The hardware consists of a SRF05 ultrasonic sensor with Echo connected to digital pin 2 and Trigger/Init connected to pin […]
Chronos controlled door lock
Addidis posted the above short video of his project controlling a door lock using the ez430-Chronos watch. He describes the hardware: Chipkit MAX32 , 2 Xbees, Chronos Control center, and a Chronos watch controlling a servo. (I’m gonna hot glue it to my door knob lock switch and not have to use my key any […]
Tellymate makes serial to video easy
The UK based crew from Batsocks develops and sells open source kits including breadboard related projects. We found a project they call the Tellymate which looks like a simple and easy way to provide plug-in video text output to any MCU project using just an ATmega8 and a handful of passive components. TellyMate is a […]
Codeacademy
Codeacademy provides an interesting way for beginners to learn Javascript coding. While not directly applicable to MCU programming, it’s sites like these that expose new hobbyists to simple programming concepts. Once picqued, this curiosity about programming can lead to more exploration of coding with MCUs. Via Adafruit.
PZST – an open-source Propeller IDE in development [ Version 1.0.1 released! ]
Andrey Demenev has been developing PZST – an open-source Propeller IDE. Not wanting to use Windows any more than necessary, he wanted to develop an open source Propeller IDE for use with Linux. He states: I have been always using Brad Campbell’s BST for Prop programming, and mostly was satisfied with it. But there are […]
ArduinoDashboard app
ArduinoDashboard is an application for viewing analog and digital pin sensor values from an Arduino in real time. The app requires you to incorporate a function from ArduinoDashboard into your sketch and upload to the Arduino. You then run the ArduinoDashboard app on your PC which reads the pin status data from the board via […]
Arduino mindreading library
Chris from LVL1 Louisville’s Hackerspace has been working on hacking brainwave sensors using the Arduino. Both the Force Trainer and Mattel MindFlex use a daughterboard from NeuroSky that outputs serial data for values of ‘Wireless link’, ‘Attention’ and Meditation. Both of these devices have the same NeuroSky board, so the *easy* hacking instructions work for […]
SimulAVR
SimulAVR is an open source simulator for AVR 8-bit Attiny and ATmega microcontrollers. SimulAVR can be used either standalone or as a remote target for avr-gdb. When used in gdbserver mode, the simulator is used as a back-end so that avr-gdb can be used as a source level debugger for AVR programs. The core of […]
OsmocomBB: open source GSM software
Osmocom stands for Open Source MObile COMmunications. The crew developing the OsmocomBB (baseband) software project presented the above talk at the DeepSec conference last November in Vienna, Austria. As they describe their efforts: OsmocomBB is an Free Software / Open Source GSM Baseband software implementation. It intends to completely replace the need for a proprietary […]
MCPU – minimal CPU on a CPLD
Here’s a project from opencores by Tim Boscke known as MCPU. It creates a minimal CPU on a CPLD with at least 32 macrocells (such as our XC9572 CPLD Dev Board with 72 macrocells.) Tim describes: MCPU is a minimal cpu aimed to fit into a 32 Macrocell CPLD – one of the smallest available […]
Arduino vitamin/pill reminder
Having to remember to take a vitamin or medication periodically can easily result in missed doses. If it’s a vitamin, probably no big deal. But if its a medical maintenance drug a missed dose can have serious consequences. Ryan Blace from ibuildthings informs us of his latest project, a vitamin/pill reminder. He designed this Arduino […]
Arduino and open source go to sniper school
Antipasto Hardware posts this cool project demonstrating how to use an Arduino and a TouchShield to keep track of shot patterns while at the range. This is a quick video showing off the Arduino Liquidware TouchShield Slide, and Bjorn Entperprises camo case, all Open Source Hardware based, at the firing range with a Remington 700 […]
Tutorial series for new Arduino PID library
To assist in understanding and using the new Arduino PID Library, Brett Beuregard has put together a tutorial entitled Improving the Beginner’s PID – Introduction. Via DIY Drones.
Gibson3d open source security software
Looking forward to the upcoming Defcon 19 conference, we note that Gibson open source software will be used there to monitor traffic. Dan Klinedinst, the project owner, writes: Some of you have seen the “Gibson” software, which models a network in 3D and shows security events on that network in real time. The code, as […]
Rosserial library for Arduino released
Michael Ferguson and Adam Stambler have released the rosserial library for Arduino. This is a new library for connecting the Arduino platform to ROS, allowing an Arduino to directly publish and subscribe to ROS messages. There are also demos ranging from controlling servos to using an Arduino and rxplot as an oscilloscope to reading temperature […]
Pong on an Atmel 8535
Eric Milkie and Jomar Ochoco from Cornell present their EE course’s final project, Pong on an Atmel 8535. For our EE 476 final project, we wanted to make something that would be fun and also allow us to use many of the different embedded control techniques we have learned throughout the semester. We thought a […]
Easily measure inductance using Arduino
Moser from ReiBot has developed a simple project for using an Arduino along with an LM399 and several discrete components to measure inductance. He says: So you need to make or measure an inductor, but you don’t have an oscilloscope or signal generator? Measuring inductance with a handful of cheap common parts is certainly possible. […]
Video: Hardware hacking for software guys
As the time for Defcon 19 nears we got to looking over last years videos and found this intro to Arduino for software guys. Dave King’s presentation is one of the better tutorials for programmers who want to learn the basics of the Arduino. An introduction for newbies, a refresher for the rest of us. […]
