Overview Different kinds of computers are designed for different purposes. The computer at the heart of your laptop is optimized for different puprposes than the one in your phone or the one in your mouse. The simplest computers are those that are designed to take inout from the phyiscal world and control output devices in

So I recently programmed a small game with python that was completely controlled by a few GPIO buttons. Over the past few days, Ive been messing around with it, finding ways to make it better, when I decided, with my small breadboard, it would be really easy to turn that three button breadboard into a

Main functions: Control the four rotators using the light buttons, rotary encoder and with a two-line display for each rotor. Same control remoted via web interface or telnet – only click to map and confirm rotating. Rotator module can directly control the motor of the rotator DC version of the phase-change AC version switching CW
I bought a Real Time Clock module (RTC) about 6 months ago and I’ve only just taken it out of its anti-static bag. With two potential projects in mind that may require an RTC, I opened the packet, wired it to my RaspberryPi and then….not a lot happened. So I had to take a closer

Everything started with the fact that the MT-5 display wasn’t what I really needed. I was in the need of checking the charging from the device using the battery: my trusty Raspberry pi (1 B at the time). I managed to stumble over this instructable (http://www.instructables.com/id/Use-Arduino-to-Com… and git project (https://github.com/xxv/tracer/). So the code and research

Here’s a diagram I did today for the interface between the photodiode and the Raspberry Pi. First, the photodiode allows small amounts of current to flow when light is shone on the device. this current is amplified by the BJT (so, just a normal transistor really) and a proportional voltage is produced across R2. This is fed
