Having received a Pi2Go Lite for his birthday, my eldest son finished assembling it and wanted to move on to some software. He’s used Scratch at school so the intention is to use ScratchGPIO (thanks @cymplecy) to control it and get it following a line. There seems to be little documentation on using the Pi2Go …

Experimenting with Thingspeak and ESP8266
A friend recently gave me an ESP12E module to play with. I’ve previously played with the ESP8266 at Open Source Hardware Camp 2015 when Omer Kilic ran an ESP8266 workshop. The workshop focused on NodeMCU and LUA. My immediate thought there was to use LUA again and I built some NodeMCU firmware to experiment with …

BBB – mount and shrink a disk image
This describes how to take an image file (origBBB.img) that has been extracted from a Beaglebone Black (BBB) – (see here for how to do that) – and shrink it so that it will fit onto a smaller SD card. First we need to be able to inspect the file system locally. We can inspect …
How to backup BBB eMMC card
Ok, so you’ve been playing with your BBB and you’ve installed this package and that package, oh and that package you forgot about. So now you want to setup another BBB in exactly the same way but wait… oh no, what did you install again and how did you configure things… this could take some …
Beaglebone Black (BBB) Simple Web IO
Some time ago I wrote a short guide to getting simple webpage based control of the GPIO pins working on a Raspberry Pi. I thought it time to do something similar for the BBB. First off, I removed unwanted services but you may not be bothered about that so consider it optional. After that, install …
Getting openssl working with beaglebone black (BBB)
Today I needed to use MD5 in a C program on my BBB (running Angstrom) therefore I looked into openssl. All seemed straight forward until I realised that my cross compiler tool chain did not include an arm version of the libssl library.
Beaglebone Black with RS232 Cape
I’ve recently bought a Beaglebone Black (BBB) and an RS232 cape (BB-BONE-SERL-03). Mine is revision A1 (important to know which, see later). At the time of writing this and at the time I bought it, I did not realise that the cape was not yet supported in the Angstrom release. Because of the move to …
Quadcopter project resumed
Over a year ago I decided I wanted to build a small Quadcopter. I bought some Hexatronic 5 gram brushless DC motors (HXM1400-2000) and some 6A Turnigy speed controllers. I designed a lightweight aluminium frame on CAD and did some research on how to stabilise it and control the four motors. I came across an …
Raspberry Pi – it’s here!
My Raspberry Pi arrived a few days ago but I’ve been too busy with work to play with it until last night when I did make time to boot it with the default Debian image. All worked perfectly and I’m impressed with the little pi 😎 I fancy trying RaspBMC on it next…
Restore a Windows7 Master Boot Record
A friend of mine recently asked me to install Linux on her laptop which I was happy to do. I installed Xubuntu alongside Windows7 as dual boot. After a few days of use, she complained that the Ordnance Survey “Getamap” webpage would not work. When I investigated, I found out that the website requires Silverlight …
