For my Spangaly Stick project, more of which later, I have been wanting to add a remote control function for the camera for a while now and with the extended winter I found I had the time. I am using an Arduino micro-controller fitted with an XBee wireless shield to respond to a keyword sent [...]
The Raspberry Pi is a small computer, and as such an obvious but important question occurred to me, and despite Google, I was unable to find an answer. So using science, LEGO, a balloon, and a compressed air supply I set out to discover if the Raspberry Pi could indeed blow a raspberry. To embark [...]
I have built a Toy Organ using a NE555 timer chip and have controlled it with the Raspberry Pi. If you are building this, remember to test with a 6v battery to power the circuit and use a 3v battery on the GPIO input points before you connect it to the Raspberry Pi. Circuit Diagram: [...]
In one of my previous posts I mentioned setting the ownership of the /sys/class/gpio to dialout using /etc/rc.local. This worked up to a point, however entries are created in the gpio when you start using them and they retain the original root group permissions, which means you are required to run your code as root. [...]
From reading the Raspberry Pi forum, I see many are wanting to control their hardware projects from the web. Here I will show a method of integrating Python with the Apache web server, and allowing the Apache server access to the GPIO and UART ports without having to run it as root, if you have [...]
Using the latest distribution of Debian for the Raspberry Pi, I wanted add myself as a user and connect to a network share. Here are the steps I took: install a couple of programs: # apt-get update # apt-get upgrade # apt-get install minicom joe set default shell to bash, add new user with groups, [...]
For the Raspberry Pi computer. More of a framework than a case.
