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 […]

RTL-SDR scanner

Al from Ear to Ear Oak has released this open source cross platform Python frequency scanning GUI for the OsmoSDR rtl-sdr library. The software scans a range of frequencies and plots the result, allowing you to find signals to investigate. The RTL dongle has a maximum bandwith of about 2.8MHz but with this you can […]

R-Pi as Arduino HDMI server

jokkebk over at Code and Life has developed a simple “HDMI server” for the Raspberry Pi that uses pyserial to receive commands over Pi’s serial interface, and pygame to display graphics primitives according to those commands. An Arduino client was written to send these commands to the Pi, drawing a string of blue rectangles to […]

Python module for transmitting and receiving infrared signals with an IR Toy

Crleblanc wrote a Python module for transmitting and receiving infrared signals with the IR Toy. It’s tested under Linux, Raspberry Pi, and is expected to work under Windows as well. It’s open source and hosted on the the Python Package Index (PyPI) linked above. I played around with the IR Toy python example and took […]

Little Wire Python library

Adam ported Little Wire’s library to Python. The library was already available in C, C++, and Processing, and now Python users can enjoy the little hack tool as well. Little Wire is multi-featured USB controlled open source hardware tool packed in a minimal form factor designed by Ihsan Kehribar. Even though it has minimal form […]

JTAGWhisperer: CPLD and FPGA programing with Arduino

JTAGWhisperer turns an Arduino into an JTAG programmer for CPLDs and FPGAs. It uses the same Xilinx XAPP58 [PDF] XSVF programmer we ported to the Bus Pirate. Mike has successfully programed a XC9572XL CPLD breakout board, but it should work with many JTAG targets. Python and pyserial are required. CoolRunner-II and XC9572XL CPLD breakouts are […]

Build a physical CPU load meter

Keegan from KSplice built this project which measures CPU load using an ammeter, Arduino and a resistor and some code. Basically, he runs a Python script on the Linux box which communicates load info via USB to the Arduino, which in turn displays the relative load on the analog ammeter. You can get the Arduino […]

Python-Arduino prototyping API

GitHub coder Akash Manohar has written the Python-Arduino Prototyping API. This code helps you to quickly prototype Arduino programs, without having to repeatedly load the program to the Arduino board. Setup involves loading the prototype.pde sketch onto your Arduino dev board, and importing the Arduino lib in your python script. The current version allows reading/writing […]

Interfacing Arduino and Python: Guide to Semi-advanced Serial Programming

Chandler has posted this tutorial on Interfacing Arduino and Python as it relates to serial programming. For this tutorial, you will need (or at least it is helpful) to have a knowledge of the Python programming language. You will also need an Arduino, and other components depending on how many of the four projects you […]

PyMite: Python-on-a-chip

Python-on-a-Chip (p14p) is a project to develop a reduced Python virtual machine (codenamed PyMite) that runs a significant subset of the Python language on microcontrollers without an OS. The other parts of p14p are the device drivers, high-level libraries and other tools. They’ve released ports for the Microchip PIC/24dcPIC, Teensy 2.0, Arduino Mega and others. […]

Python wins the TIOBE Programming Language Award of 2010!

Python wins the TIOBE Programming Language Award of 2010! Python programmers love this language’s simplicity and it has become a very useful tool for those who love fast prototyping and quick development time. It has been proven useful in a lot of areas: – GUI programming (such as wxPython) – Engineering calculations and computations (such […]

Bus Pirate oscilloscope script

Hwmayer created a simple oscilloscope python script for the Bus Pirate. The latest version adds triggers, and sampling rates up to 1K using a new command in the upcoming firmware. Get a Bus Pirate v3b for $30, including worldwide shipping at Seeed Studio. Adafruit also has the Bus Pirate and probe cables in stock and […]

Bus Pirate project welcomes audiohacked

Please join us in welcoming audiohacked to the Bus Pirate project. audiohacked wrote the excellent Python wrapper for the new Bus Pirate binary modes, and now he’ll be updating a copy in the project SVN too. pyBusPirate makes Bus Pirate scripting easy for Python developers, and it’s the most complete binmode reference implementation available.
