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…
New GPIO breakout with analog inputs from Nwazet for the #RaspberryPi
Fantastic new product from Nwazet. The ‘Key Lime Pi’ kit breaks out the Raspberry Pi’s GPIO connector, adds eight 10-bit analog inputs, converts the Pi’s serial interface into astandard FTDI connector and allows for external power headers to be added…
Bicolour LED Square Pixel Matrix with I2C Backpack
Adafruit have created this lovely little LED matrix which would be a great addition to any bits box! Phenoptix are stocking this and you can buy one for a not-unreasonable £14.89. It’s driven by I2C and a built-in driver chip…
Programming Pi-Face with Java & Pi4J on #RaspberryPi
Robert Savage has published another of his Java/Pi4J articles. This time, he tackles the Pi-Face expansion board and provides some example code for those looking to use Java on the Raspberry Pi! Read his article here.
#RaspberryPi sprinkler / irrigation extension board – OpenSprinkler Pi / @Raspberry_Pi
Rayshobby has just announced a new add-on board for the Raspberry Pi. It’s a sprinkler or irrigation extension board for the Pi that provides direct access and control of sprinkler valves. Read the article about the board here
#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…
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…
