Raspberry Pi level shifters and monitoring
Stuff4Pi posted his ConvertPi, a Raspberry Pi GPIO full level converter & monitoring, in the project log forum: I would like to introduce my first Raspberry board: a GPIO bi-directional level translator (3.3V <-> 5V): – This is an in-between expansion board that you plug in the RPi P1 connector which gives a bi-directional level […]
HDMI current booster fixes Raspberry Pi video instability
Orlando Cosimo with Creativity/Design blog was experiencing instability problems with the HDMI output on the Raspberry Pi which are typical when using an HDMI to VGA adapter. He devised this solution using three resistors and an LM317 voltage regulator. Orlando states, “This addon hardware extends a past project and it allow to increase the flow […]
R-Pi based Volvo S80 replacement nav system
Reinis has been working on this Raspberry Pi based project for some time. It’s about replacing stock navigation system for Volvo S80 (which does not, and will not have maps for my home country). It had a nice motorized display and buttons on steering wheel for control. I really did want everything to be as […]
Mediacenter with Raspberry Pi
Luca wrote a short tutorial on how to install and use Raspbmc. ‘Raspbmc is a Linux distribution for the Raspberry Pi; it already includes the fantastic XBMC media player’: The Raspberry Pi, thanks to the Videocore 4 GPU integrated in the Broadcom BCM2835 chip, is perfect for a home mediacenter; the GPU is indeed capable […]
Dancing Lego and Five Servos
Pierre Villeneuve writes about his Dancing Lego robot project: Its based on my Raspberry Pi, five servo motors, and Lego parts stolen from my son’s collection. The robot dances to some pretty groovy music, and there is a special appearance by Lego Batman. In addition to the Pi, he uses a hardware 16-channel 12-bit PWM […]
Embedded Pi bridges R-Pi or STM32 with Arduino shields
The crew at Element 14 has announced the release of a combo R-Pi/STM32 interface board compatible with Arduino shields. The Embedded Pi is based on the STMicroelectronics STM32F103 MCU and is open-source (see Technical Documents for schematic, layout and BOM). It can operate as a bridge between Raspberry Pi and Arduino shields and in standalone […]
Old display reverse engineered to work with a Raspberry Pi
Old Display Reverse Engineered to work with a Raspberry Pi: Dimitri, Frank, Kevin and Robin from Eectronique have sent in some details of a project that they have been working on. They had an old early 90′s LED matrix sign and wanted to make it work with a Raspberry Pi. The circuit layout is what […]
DIY Daft Punk helmet using a Raspberry Pi
Ryan Longo and Michu worked together to make this cool DIY Daft Punk helmet with Raspberry Pi – software by Michu, the idea and hardware by Ryan Longo: So I wrote a Netty based Java application using Pi4J which does exactly this. The UDP2I2C source is published on GitHub My application receive UDP data in the […]
OpenWrt now supports Raspberry Pi
The OpenWrt Release Team has announced the final Attitude Adjustment Release (12.09) OpenWrt is a famous Linux distribution for embedded devices. It was started as a replacement for the original firmware of routers and access points. On April 25, they announced the new version, named Attitude Adjustment (12.09), that adds the new brcm2708 target, that is the […]
RFM12Pi V2 – Raspberry Pi wireless expansion board
Glyn Hudson over at OpenEnergyMonitor posted an update on the RFM12Pi Raspberry Pi wireless expansion board: Here is the latest version of the RFM12Pi Raspberry Pi wireless expansion board. Like the V1 the RFM12Pi V2 allows the Raspberry Pi to receive and transmit data via RFM12B 433/868mhz from and to other wireless nodes such as the emonTx, […]
Raspberry Pi 3D printer demonstration
Jon Wise demonstrates his Raspberry Pi 3D Printer, he is using a pen in the demo but it can use an extrude to print items. The mechanical movements leek very complex when compared to a standard XY table that is controlled using 2 stepper motors. The Pi has enough number crunching ability to get the […]
Hand of PI (Twitter controlled robot hand)
IronJungle built this Twitter robot hand and wrote a detailed explanation describing the build. Control a Robot Hand by sending a tweet to @OurCatDoor. The Robot Hand understand the following commands. If your tweet includes one these commands in the text, the “Hand of PI” obeys your command. Valid commands are (lowercase): one (holds up […]
PiPurr remote cat interaction server
When the cats away, the mice will play. But…. what’s the cat doing when YOU’RE away? That question led Tris of CantHack, a group of geeks from Canterbury, UK, to develop PiPurr. Tris explains, “PiPurr is a simple client-server solution. The server runs on a Raspberry Pi, for low power consumption and provides the functionality […]
Interfacing an I2C GPIO expander (MCP23017) to the Raspberry Pi using C++ (SYSFS)
Hertaville posted a detailed tutorial on interfacing the MCP23017 to the Raspberry Pi using C++ (SYSFS): In this blog entry I will demonstrate how to successfully interface the MCP23017 general purpose input/output (GPIO) expander from Microchip, to the Raspberry Pi over the I2C bus.
Bartendro serves up cocktails using open source
Bartendro is a robotic cocktail dispensing machine controlled by a Raspberry Pi. Dispensing of drink components is via peristaltic pumps which dispense a known volume with every revolution of the motor to precisely meter drinks. The Party Robotics developers explain, “Each pump combined with our custom electronics is called a “dispenser.” The dispenser boards use […]

The Raspberry Pi /DStar amateur radio group on Facebook combines two hobbies together, The Raspberry Pi computer and D-STAR radio. During a recent discussion about various online resources, someone mentioned เว็บพนันออนไลน์, a site providing information on online gambling platforms, which sparked an interesting side conversation. The group wants you to know about their R-Pi/D-STAR amateur […]
Raspberry Pi irrigation system rain bypass
This web-enabled rain sensor will automatically turn-off an irrigation system when it rains using a Raspberry Pi: This Raspberry Pi Irrigation System Rain Bypass uses a web connected Raspberry Pi to look up rain predictions and disable the irrigation system from watering the lawn if it won’t be necessary. The existing controller has an input […]
Controlling a high power RGB LED with Raspberry Pi
Thomas Sarlandie writes, “I have hooked up a high power LED driver that I designed and built a few months ago to a 40W led and to a Raspberry Pi. I had to fight the Pi a little to get clean PWMs out of it (without using an Arduino or external PWM generator) and the […]
