Tim Massaro has written an Instructable to create a Pi Joke Machine. He’s used a PiFace Control and Display (which is an LCD screen with added buttons) and wrapped it all up in a project box.
PWM dimming of an LED on the #RaspberryPi
A father-and-daughter team wants to control servo motors using PWM (Pulse Width Modulation) on the Raspberry Pi. As a demonstration of how possible this is, they’ve started out by using PWM with an LED to fade it up and down. To do this, they’ve used the Occidentalis distro from Adafruit (although this was probably overkill as you can do similar on plain ol’ Raspbian).
Control a LEGO motor with a #RaspberryPi and a Gertboard
Karl Herrick has taken a Gertboard and a 4.5v LEGO motor and linked them up to the Pi. He’s then looked at Alex Eames’ Python Gertboard suite and written some test scripts as a proof-of-concept.
Fish Dish Pi from PiSupply for the #RaspberryPi
Paul Brown’s done a nice write-up and exploration of the Fish Dish expansion board over on smstext. Nice use of Daniel Bull’s BerryIO, too.
Tweeting with the #RaspberryPi
Alex Eames at RasPi.TV has written his second post in a series he’s doing using Tweepy to send/receive tweets on a Pi.
Complete #RaspberryPi course from Intertech
Training company Intertech has been very generous and published the complete set of course materials from their Complete Raspberry Pi Training class.
Here are the segments:
- Set-up the Pi, install the operating system and get the training files onto the Pi.
- Learn some basic Linux commands, get into the X-windows GUI and safely shutdown the Pi.
- Learn to program in Java by writing a Hello World program.
- Create and run a Java Swing program under X-windows.
- Use a simple Java networking program to explore networking concepts.
- Use Java to play sounds on your Pi.
- Build a traffic light circuit on a breadboard and program it using Java.
- Connect a switch to a breadboard and read input using Java.
- Add a light sensor to a breadboard and use Java to read light levels.
- Connect a temperature sensor via breadboard to the Pi and use C to take readings.
