Serial communication between #RaspberryPi and #Arduino
Great little tutorial on powering an Arduino from the Pi’s 5V pin and also communicating via serial from the GPIO pins. Well worth a look if you want communication between the two to be faster. As the article points out,…
Changing the hostname of your #RaspberryPi
For those people who (like me) have more than one Pi, and even for those who have more than one SD card, the ability to change the hostname is invaluable. Here’s how you do it. You need to change two…
RFM12Pi #RaspberryPi Expansion board kit (433 Mhz)
With the addition of a 433Mhz RFM12Pi expansion board to receive data via wireless from other OpenEnergyMonitor modules (e.g emonTx) a Raspberry Pi running emoncms can be used as a powerful emonBase base-station to log, process and visualise energy, temperature…
Using a #RaspberryPi as a Ninja Block @Raspberry_Pi
“Ninja Blocks are tiny cloud enabled computers that can sense their environment by receiving input from a variety of sensors & can affect their surroundings by controlling lights, power sockets, and other actuators.” The company making the Ninja Blocks have…
Volunteer your #RaspberryPi to analyse SETI data / @Raspberry_Pi
Daniel Carrion at Burde View has been getting “BOINC” up and running in order to use his Raspberry Pi to analyse telescope and other astronomical data. “BOINC is open-source software for volunteer computing and grid computing. It uses to the…
Warn people off with a #RaspberryPi motion sensor and sound effect
Here’s a quick tutorial on using an ultrasonic range sensor to detect nearby movement and play a sound to ‘warn’ people off! Sensors and Raspberry Pi: I2C connection.
Proto-Plate #RaspberryPi Breakout Board
A few people at the MK Raspberry Jam were asking today about a board that plugs into the Pi’s GPIO pins that both myself and Daniel Bull are using. Well, here’s a link to an eBay lot currently selling these…
CT Scanner made with Arduino
Not strictly Raspberry Pi-related, someone has made a CT scanner out of an x-ray tube bought from eBay and an Arduino. Very cool. CT Scanner made with Arduino (from parts of eBay!) | GeekBoy.it.
Read two sensors on the same GPIO pins with the I2C bus on the #RaspberryPi @Raspberry_Pi
This great Instructable finally opens my eyes to what can be achieved using I2C. In short, it gives instructions for reading two sensors on the same GPIO pins. In other words, you wire both sensors up to the same two pins…
