PCB for Raspberry Pi WH1080 weather station
A PCB for Raspberry Pi WH1080 weather station by Andy Ayre of BritishIdeas: Previously I wrote about using a Raspberry Pi to receive 433MHz signals from a WH1080 weather station. This is the mess of wiring I came up with. This worked fine until it stopped. I probably didn’t crimp a wire properly and too many knocks […]
Review: Kano DIY computer kit
Steve Schuler has posted this review of the Kano DIY computer kit on Science 2.0. I’ve lost count of how many computers I’ve built over the years, but I think it is safe to say that the Kano Computer was the easiest build ever. So simple a child could do it. Kano founders, Yonatan Raz-Fridman, […]
A breakout board for the Raspberry Pi to learn Python
RPi Board, a board to learn Python with the Raspberry Pi by Jesus Echavarria. He writes: Once I check that all is Ok, it’s time to start programming. There’re a lot of manuals and references over internet of how to start programming in Python. Here I’ll cover the basic examples to start working with the board. […]
PiGateway upgraded to MightyBoost
Felix of LowPowerLab writes: Enter MightyBoost – a multi purpose PSU that can supply the power a Pi needs, and also be controllable by a Moteino (including wirelessly controllable if needed) such that it would duplicate the functionality of ATXRaspi. And most importantly to be able to run it on battery backup in case power […]
A four channel remote control using EnOcean Pi
A four-channel remote control built using the EnOcean Pi by Kerry Wong: In my last couple of blog posts, I did a brief overview of the EnOcean Pi sensor kit from Newark and demonstrated how to compile and run the example code using a Raspberry Pi. In this blog post, I will show a real world example […]
ASTROGUN R-Pi based asteroid game
Avishay has developed the ASTROGUN, a Raspberry Pi based asteroid shooting gun and video display system. He originally designed the project along with Maayan Dreamer for the Jerusalem Mini Maker Faire, held last June. The game is pretty simple – the player stands and has to shoot Asteroids that are coming towards him from any […]
Reverse engineering a wireless soil moisture sensor
Ray Wang at Rayshobby has been working on reverse engineering a wireless soil moisture sensor. He writes, “At the Maker Faire this year I got lots of questions about soil moisture, which I knew little about. Recently I started learning about how to build my own soil sensor, and came across this cheap 433MHz wirelss […]

Posts Raspberry Pi power usage to Xively, MobileWill’s latest project: Realtime graph of Raspberry Pi power usage on the web. So using Xiviely and my USB Tester I am logging voltage, current mWh and mAh to the web. Source code and designs are available on GitHub. Via the contact form.
AnalysIR adds LIRC export format
The AnalysIR crew note that users of the USB IR Toy may be interested in a new feature they just announced allowing export to LIRC format. This opens up Raspberry Pi & most Linux systems… You can get IR Toy v2 for $22.05, including world wide shipping. Via the forum.
Picberry: R-Pi / Allwinner A10 PIC programmer using GPIO connector
WallaceIT has developed a Raspberry Pi / Allwinner A10 PIC Programmer using GPIO connector. “It currently supports dsPIC33F and PIC18FxxJ families, though other “code-programmed” families can easily be added. Feel free to use and comment it! Any feedback will be appreciated!” Via the contact form.
The Drinkmotizer – a Raspberry Pi drink mixing robot
Cabe Atwell wanted a way to have a robot serve up a mixed drink efficiently and economically. He developed the Drinkmotizer, which uses a Raspberry Pi in combination with an Arduino to construct the dream project of many a maker. What makes this drink mixing robot different from other designs? Cabe says this machine builds […]
Asterisk PBX on R-Pi
While you don’t hear quite as much as you did a few years ago about Asterisk, the free, open source framework for building communications applications, there’s still an active community developing and extending the code. The software essentially allows you to run your own VOIP Private Branch Exchange (PBX) on your home computer. The crew […]
R-Pi and RTL-SDR = AFSK transmission between two Linux boxes
This video depicts the successful transmission of AFSK data via a radio link between two Linux machines using a R-Pi and an RTL-SDR dongle. The crew at Kprod posted this cool RTL-SDR project on their blog. They use minimodem to do the encoding in a FLAC or in a WAV format, then use the R-Pi […]
EFERGY E2 Classic FSK decoding using RTL-SDR and R-Pi
Nathaniel Elijah has posted the a complete working prototype of an EFERGY E2 CLASSIC Transmission decoder using a Raspberry Pi and RTL-SDR USB Dongle. The EFERGY E2 Classic is an electrical usage monitor which displays information received from associated wireless energy sensors. Nathaniel writes, “It is now possible to capture those 10s to 20s power […]
DIY R-Pi based haunted mansion portrait
Brandon Etto designed this changing portrait Halloween prop. The hardware consists of a Raspberry Pi (Model B) and a 19″ widescreen LCD Monitor. Construction details and code links can be found on MAKE.
Amateur radio TV beacon inside CCTV case
András Veres-Szentkirályi write about an interesting project The Budapest hackerspace (hsbp.org) did some joint work with a local ham radio club and created an SSTV beacon housed inside a CCTV case that takes an image of its environment and transmits it using slow-scan television over ham bands. There’s currently one experimental device installed, and since […]
Video: R-Pi, media centers and AppleTV
In this presentation from the September 29, 2013 session of the Derbycon conference in Louisville, KY, David Schuetz, Senior Consultant with Intrepidus Group, demonstrates the use of the R-Pi as a media center and content server. He devised the project as a way to entertain his children on car trips, now that they’ve graduated from […]
Raspberry Pi Pandora streamer
Here is a Pandora music player based around the Raspberry pi. It features a screen that provides basic user interface control, and displays the song title. My basic justification for the project was that I listen to a lot of music on Pandora or Spotify while reading and doing homework, but having it up on […]
