Nanode: networked Arduino node

Nanode is a low cost Arduino-like sensor node board intended for web connectivity applications. It allows you to develop web based sensor and control systems – giving you web access to six analogue sensor lines and six digital I/O lines. The schematic and other details can be found on the project’s Thingiverse page. The code […]

Using the EUSART

The term UART (Universal Asynchronous Receiver Transmitter) is the technical term for the good old serial port found on most MCUs. The term USART similarly refers to a serial port capable of handling both synchronous and asynchronous operation. Over the past few years, Microchip has been integrating an updated serial port into many of their […]

Vienna hackerspace autoposts realtime project videos

It seems like every hackerspace has their own means of communicating status messages to their members. The hackers at MetaLab in Vienna have put together a rather novel way of letting the world know they have completed a project. While some hackerspaces simply notify their members that they are open for business, they take things […]

Free Oreilly workshop – Processing and Arduino in Tandem: Build a Mixer

Oreilly is offering a special follow-up to their earlier Processing and Arduino course. “Processing and Arduino in Tandem: Build a Mixer” will be presented free online by Instructor Joseph Gray on two successive Fridays. The course makes use of the projBox, a control box with installed potentiometers, switches and LEDs, which interfaces with the Arduino […]

Infosec: using fuzzers to find vulnerabilities

Infosec Resources has a free online tutorial, An Introduction to Fuzzing: Using fuzzers (SPIKE) to find vulnerabilities. While not directly related to microcontrollers, this resource provides a hands-on guide to using open source Linux tools to find vulnerabilities in code on a networked Windows machine. To fully participate in this demo, you’ll need two machines […]

Wireless sniffing and jamming

Recently Travis Goodspeed posted an article about using goodfet.cc to sniff radio traffic from the Chronos watch by TI and the iClicker handheld classroom remote. In addition to the sniffing capabilities, the project can also be used to jam RF signals as well using the IM-ME device illustrated above. Via Hack a Day.

HACK: Open source USB stack on MCP2200

Microchip has a new USB->serial converter chip called the MCP2200. We suspected they made this chip from a 20-pin PIC. The MCP2200 pinout is like other PIC uCs, and it has similar reset pin and internal voltage regulator circuits. We hooked up our trusty PICKIT3 and read the device ID. The MCP2200 was recognized as a […]

Logitech Revue rooted

GTV Hacker has developed a guide to installing applications and rooting your Logitech Revue. The new hack uses the Revue’s UART1 port to upload a start-up script which allows “root” access, allowing the installation of your own apps and access the full filesystem. You need to solder a set of leads to the mainboard and […]

DEMO: MMA7455L 3-axis accelerometer

Here’s a demo of the MMA7455L 3-axis accelerometer in SPI mode using the Bus Pirate. We’ve got this sensor on a breakout board for $15. The MMA7455L has: 2/4/8g selectable measurement range 10bit or 8bit output force and pulse detection with interrupt I2C and SPI interface 3.3volts Get the MMA7455L breakout board for $15 at […]

Bus Pirate and the AR1010 FM radio

Fell did a small write up on using the Bus Pirate and the AR1010 FM radio module. Includes a simple python script using pyBusPirateLite that tunes the AR1010 to a particular station using the Bus Pirate. Via the contact form. Get your own handy Bus Pirate for $30, including world-wide shipping. Also available from our […]

DEMO: 96×16 OLED display

It has been a while since a demonstration was posted. We whipping up new projects for you like the USB LCD backpack, HVP adapter, Buspirate v4 prototype, breakout boards, and several other project that are TOP-SECRET but will be released soon! Now that everything is at to manufacturing, we have some time off for our family and for fun stuff. […]

Android controls robot with Bluetooth

PocketMagic demos the use of an Android phone’s Bluetooth capability to transmit commands to a module interfaced through an Atmega8 with a robot car. While this project controls a Perseus 3 robot platform, the code and circuit could be easily adapted to use with any device that could be interfaced with the Atmega8, and the […]

Demo: Sure-electronics DE-DP014

To demonstrate some of the new commands from the new firmware 5.2, we interfaced the DE-DP014 from Sure-electronics. This is a single, SPI-like controllable 1.8″ single 5×7 dotmatrix. It has an on-board PIC controller which stores a special ASCII font. The package consist of two units, a simple demo board and two 10-pin cables. Sure […]
