Create a 3x3x3 LED cube with the Raspberry Pi
Jacob from Coventry Makerspace has taken 27 LEDs and soldered them together as a cube. He’s then hooked up each of the 9 columns of LEDs to GPIO pins and also to ground, via transistors. The transistors are also hooked up to…
Basic temperature reading and logging with the Raspberry Pi
Matt over at Raspberry Pi Spy has written a great tutorial on using the BMP180 to take temperature readings over I2C and then logging them online via thingspeak.com. He’s provided all the code online for you to download and full wiring…
Raspberry Pi dog monitor – with lasers!
Dave Young wanted to stop his dog from jumping up and taking food off the kitchen work surfaces (I can sympathise!) when he wasn’t in the room. So, he hooked up a laser detector circuit to a Raspberry Pi and programmed…
Raspberry Pi motion sensor with realtime alerts
Eric Grossman over at PubNub has written an interesting tutorial which uses an ultrasonic distance sensor. The sensor detects motion by taking constant readings and then uses the PubNub service to ‘subscribe’ to any alerts generated. Read more here.
Read temperature, pressure and altitude with the BMP180 sensor on the Raspberry Pi
Malcolm Maclean is developing an eBook for the Raspberry Pi and it’s available for you to read online. One of the sections of the book is all about the brilliant little BMP180 sensor (pictured above). This sensor, which replaces the larger…
Raspberry Pi powered ID photos with this booth
Roo Williams was tasked with improving on a company’s method of taking ID photographs. What he came up with was a Raspberry Pi with a camera module which talked via a Flash web interface to the subject’s mobile phone. He…
Using a Raspberry Pi 2 to make MIDI music
JosephEarnest has taken a Raspberry Pi 2, a USB digital-to-analogue converter (for sound output) and some other components soldered to stripboard to create a midi input/output device. The software is written in Python and cython and is available here. He’s made…
Raspberry Pi clock and weather display
Kevin Uhlir has taken a Raspberry Pi and a large HDMI screen and then programmed the Pi to use the Weather Underground API to create a clock and weather monitor. The software will run on Windows, MacOS and Linux as long…
