Raspberry Pi running 4 5V stepper motors from GPIO
I’ve been playing around with some stepper motors with driver boards that I bought from eBay. They have a lot of potential and I’m planning to use them on an astronomy project… but more on that later. The motors were £1.66…
#RaspberryPi Python class for controlling 28BJY-48 stepper motor with ULN2003 board
Stephen Phillips has written an excellent piece of Python to control a 5V stepper motor from the Raspberry Pi. This worked first time for me and it’s formed the basis of a new project that I’ve unimaginatively called ‘stepper-pi’. The code for stepper-pi is…
Wireless inductive charging for the #RaspberryPi
Shea Silverman has been playing with Seeed Studio’s Wireless Charging Module and has managed to set it up so that his Pi his powered wirelessly! (Well, almost wirelessly, you’ll see what I mean!) Friday Post: Baked Raspberry Pi | Shea Silverman’s…
Using an Ultrasonic range finder with the #RaspberryPi from Java.
Another excellent post from Carl Hughes. This time he takes readings from an ultrasonic range finder connected to his Raspberry Pi using Java. Read his article here
Technical details for a compact, headless #RaspberryPi
This project has resulted in a Raspberry Pi with a 4-line LCD screen, a battery pack, indicator LEDs and control buttons so that a headless Pi can be monitored and controlled without any other input device. It’s rather neat and…
Building a #RaspberryPi Cluster / @Raspberry_Pi
Afkham Azeez has built a Raspberry Pi Cluster with more than a dozen Pis. The really clever part is that he constructed a custom power board with switches and USB ports to control power to each Pi separately. There is also a…
#RaspberryPi using Scratch to control RC car over GPIO
Winkle Ink’s been tinkering with an old remote control car and a bunch of transistor based driver circuits. What he’s come out with is a remote control car that you can program from Scratch. It’s not the most precision control…
Bicycle Dashboard on the Web using a #RaspberryPi
Jeremy Blythe has been busy. He’s created a live web bicycle dashboard using his ControlMyPi project. The Pi is carried onboard his bike and then he uses a combination of the Raspberry Pi a 3G dongle the Adafruit Ultimate GPS Breakout…
DSTAR amateur radio net with #RaspberryPi
The Raspberry Pi /DStar amateur radio group on Facebook combines two hobbies together, The Raspberry Pi computer and D-STAR radio. The group wants you to know about their R-Pi/D-STAR amateur radio net which will be conducted most Monday Nights starting February 18th, 2013 on REF026A…
