On the Raspberry Pi, there are several connections which can be used for expansion: 1, The Rpi GPIO (General Purpose Input/Output) pins are exposed, that means that expansion boards are able to talk directly to the CPU. 2, The DSI connector will allow low-level interfacing with LCDs and other displays. 3, The CSI connector will […]

I know it has been ages since I posted here so I thought I would put something up for Halloween. I have a brilliant and simple project here. It’s easy to understand and, more importantly, it actually does work. I accidentally scared myself with it once! So I know it does. A Raspberry Pi is

In this instructable I will show you how to use a cheap PICAXE micro-controller as a multiple channel analogue to digital converter. We will be using I2C to access the PICAXE, which will be writing the adc values into the memory registers. The Raspberry Pi does not have a built in ADC, which is unhelpful

A general purpose 16 SPDT channel relay board (power supply 24VDC) for switching high-current electrical loads (both AC and DC) siuch as motors, lights, pumps, contactors and more. With this relay board, any logic-level signal from 3V up to 30V can be used to activate a relay (it may be controlled direclty by microcontroller TTL

f you want to make some simple electronic circuits for your Raspberry Pi, you may need some useful (software and hardware) tools. Hardware tools Breadboard The breadboard (aka prototyping board, or plugboard) allows you to prototype your electronic circuits without the need to solder components. You just have to plug them into the board, and

In this instructable I describe a method for automatically resetting a Banana Pi when it freezes, or looses power and does not restart. This method will also work for the Raspberry Pi as long as the correct GPIO pins are used (which I believe are slightly different than the Banana Pi pins). The method is

Hard to choose between Raspberry Pi, BeagleBone Black, and MinnowBoard Max? Now there’s another choice: the open source MIPS-based “Creator CI20″ dev board. In a bid to harness some of the energy and enthusiasm swirling around today’s open, hackable single board computers Imagination Technologies, licensor of the MIPS ISA, has unveiled the ISA’s counter to

The Pan/Tilt kit that we sell, developed by Dagu with the guys over at Let’s Make Robots, is a great way to mount mobile sensors on your robotic projects. In this tutorial we look at how you can control the Pan/Tilt kit with a Raspberry Pi and the Python programming language. Required Materials and Equipment

Presumably everyone knows what the Raspberry Pi is, by now, so I’ll not start there. You may or may not know that the RasPi has General Purpose Input/Output (GPIO) pins as standard. Some of these provide 3.3v power, some provide 5v power, some are grounded and the others can be used for input and output.
