pi_piper – an event-driven Python library for #RaspberryPi
Jason Whitehorn has written a library for Python to control/read the GPIO pins based on events. It means you can write code like: watch :pin => 23 do puts “Pin changed from #{last_value} to #{value}” end #Or after :pin =>…
Run Raspivid from Python on the #RaspberryPi
Martin O’Hanlon has created a brilliant Python class to control raspivid. It works on a threaded basis so you can trigger the camera without causing your calling code to wait for it to finish. I recommend this to anyone who…
Cheap wireless communication between a #RaspberryPi and an #Arduino
Conor O’Neill has worked out how to get the Arduino and the Pi communicating wirelessly using some cheap nRF24L01+ modules. These things cost all of 1.26 Euros and seem like a great addition to your electronics kit. Read more here
Karaoke machine with a #RaspberryPi and USB microphone
Over at Pi Fun, Dextrus has written a tutorial on creating a karaoke machine with the Pi. You just need a USB microphone and he recommends running it headless using a wifi dongle. Here it is in action: Read more…
#RaspberryPi moisture sensor tutorial
Jeremy Blythe has written an excellent, in-depth tutorial to help you read moisture levels using an analog sensor. Particularly of interest to me is the wiring up of a MCP3008 analog-to-digital converter. It will come in most useful when I…
Public transport tracking with a dot-matrix wall board and a #RaspberryPi
Pavel Shved had a problem. He was always late for the bus. So, he found one of those dot-matrix wall-boards… wired it up to a Raspberry Pi, wrote some code to grab and display information from the internet about bus…
Fixing Errors While Upgrading #RaspberryPi
Over at CodingEpiphany.com, they’ve written a blog post about correcting errors from apt-get update/upgrade. Take a look if you’ve ever had problems. Read the article
RasPi.tv shows how to use the PiGlow for #RaspberryPi with GPIO control
The PiGlow is a lovely little GPIO board from Pimoroni which features three arms of ultra-bright LEDs. Alex over at RasPi.tv has put it together with his own circuit board and, in his new video, shows us how to control…
#RaspberryPi timelapse camera inside a coffee tin
Using the Pi, the camera module and an Illy coffee tin, Jim at Fotosyn has created a simple timelapse camera. He used an AA battery converter/holder for power, but any USB power unit will do. Nice little project. If you’re…
