Phillip Burgess of Adafruit has used the Adafruit LCD Pi Plate to build a Raspberry Pi radio that can play Pandora streaming over Wi-Fi:   http://www.adafruit.com/blog/2013/04/12/make-a-raspberry-pi-wifi-radio/ Raspberry Pi, the little wonder-puter that’s taken the world by storm, is so affordable that we can create nifty single-purpose “appliances” around them without shame. Here’s our take on one of the more popular such applications: internet streaming media, the ...
PiFace controlling DC motor speed (notice the LEDs fading in and out, too) [http://www.youtube.com/watch?v=QO9lDBBy5s8]   To follow up my last post, PiFace relay tricks: metronome & "playing" middle A, I'd like to show how Gordon's PiFace PWM code can be used to control the speed of a DC motor connected to one of the PiFace output screw terminals:     And the installation instructions:           Cheers, Drew   ...
Gordon of WiringPi and drogon.net has created a nifty metronome demo program for the PiFace:   Here's the source code:   And the installation instructions:   As you'll notice in the above instructions, Gordon has figured out how to do PWM with the PiFace outputs!  Here is rather noisy application, middle A being "played" on the relays:   The background of Gordon's PWM PiFace work is in this comment on his blog: https://projects.drogon.net/raspberry-p ...
I hosted a webinar today on the PiFace and Gertboard.  I thought it might be helpful if I shared the resources I used to create the demostrations:   PiFace Univ. of Man.

I previously described the great Adafruit RGB LCD + Keypad Pi Plate and showed off the demo program.  I spotted this inspiring project on the Adafruit blog by David Singleton:   Raspberry Pi Timelapse Controllerer A few weeks ago, I found this beautiful video on Youtube – a timelapse video of stars and the Milky Way. Seeing the stars appear to rotate overhead (due to the rotation of the Earth) and the intricate structure of our own galaxy gave me a profound feeling of the scale ...
I'm quite excited about Adafruit's new RGB LCD + Keypad Pi Plate which: lets you control a 16x2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the R-Pi! The best part is you don't really lose those two pins either, since you can stick i2c-based sensors, RTCs, etc and have them share the I2C bus. This is a super slick way to add a display without all the wiring hassle.   The kit is offered with 3 different LCD options:   RGB Positive 16x2 LCD&# ...
