Etch-a-Pi – Etch-a-Sketch with the #RaspberryPi
Sean Clark has written up his project to create an Etch-a-Sketch powered by a Raspberry Pi using stepper motors. Read all about it here
Perl and #RaspberryPi – using the second I2C bus
Mark Dootson has been doing some experimental work with the second I2C bus available on the Pi by soldering pins onto the P5 header. He is then using Perl to communicate with the bus, although I’d imagine it would be…
A tiny Arduino board for the #RaspberryPi
David Whale has done a tutorial on creating a very cheap Arduino clone that you could use with your Raspberry Pi for doing things like analog inputs, or anything else you can find in an Arduino book. Read more here
Connecting LM75 temperature sensor to the #RaspberryPi, reading it in Java
Jan Krueger has written an in-depth tutorial in connecting up a bare LM75 temperature sensor to the Raspberry Pi. Plenty of photographs to show the connections and a table to show the pin connections. He has then used the Pi4J…
Kindleberry: The Sequel for #RaspberryPi
Max Ogden has created a new version of the Kindleberry Pi (hacked Kindle into a display for he Pi) with the Kindle Paperwhite. Read all about it here
Connect a PSP Analog Joystick to the #RaspberryPi
Jason Birch has been tinkering with a PSP joystick and his Raspberry Pi. Very simple to set-up and only requires an MCP3002 analog-to-digital converter chip (and a few other small parts you likely already have). Read the tutorial
#RaspberryPi powered Cat Feeder
Hack Factory member “Videoman” has created a cat feeder with a Raspberry Pi brain to automatically dispense cat food. Read all about it here
DIY wireless MIDI-OSC bridge with the #RaspberryPi
Not much I can blog about here – if you know anything about midi, this will interest you. Read about it here
#RaspberryPi model A powered from 2 AAA batteries
Very neat video of a Raspberry Pi model A running from just 2 AAA batteries all in a ModMyPi case. Really clever stuff.
