IN October 2015, we had the launch event for the “Lightning Dress”, a garment we’ve been working on as a group in the local Fablab for the last 6 months. It’s got approx. 700 RGB leds, all individually addressable, so it gives great flexibility for generating interesting patterns and effects.

Damp-Pi – Room Moisture Extraction with Raspberry Pi
Over the last while I’ve been having a problem with excess humidity in the shower rooms. Imagine that, the builder never put in extractor fans when the house was built! Anyway, I could put in those fancy extractor fans with the built in timers or humidity sensors, but I decided to do things the more interesting way, by using a small computer to read the values from a humidity sensor in each room, and based on the readings, turn on the fan until the humidity was reduced to an acceptable level.

Raspberry Pi 2 Benchmarked
I got myself a new Raspberry Pi 2 Model B this morning. I was intrigued by its quad-core cpu and how it would stack up against the other single board computers that I’ve benchmarked in the past, which were:
- Raspberry Pi Model B+
- Beaglebone Black
- Intel Edison
- Imagination MIPS Creator CI20
Creator CI20 Benchmarked
I recently got a MIPS Creator CI20 from the guys at Imagination to play with. So here’s a quick of my first impressions, including a few benchmarks with sysbench. Performance overall was quite good compared to a Raspberry Pi 1 model B+, and even was pretty good compared to an Intel Edison on the CPU benchmark. Continue reading “Creator CI20 Benchmarked”
3D Printed Raspberry Pi Model A+ Case
The Raspberry Pi Model A+ is very cute. But it’s even cuter with it’s own 3D printed case. Here’s a case design for you to download and print yourself!
Raspberry Pi Model A+
The Raspberry Pi foundation announced it’s latest member of the Raspberry Pi family, the Model A+. This is a departure from the usual credit card form factor, in that they’ve managed to knock off 20mm from the length, resulting in a very nice 65x56mm form factor.
First Intel® Edison project – DSLR Camera Controller
I’ve been working on camera hacks for a couple of year now. It started with the CameraPi, which was a Raspberry Pi mini-computer stuffed into an old battery grip for my Canon 5D Mark II Camera. Then came various variants on that, including a DIY time-lapse rail, the results you can see in the time-lapse section of this website. Theres’ also some water droplet photography, automated focus stacking, and even a bark activated door opener, not to mention the PiPhone.

Raspberry Pi, Beaglebone Black, Intel Edison – Benchmarked.
Recently I took delivery of an Intel Edison with a Mini-Breakout Board. I was awestruck by the size of the thing, but it was not until I started using it properly for a couple of projects that I noticed that it seemed a little bit ‘snappier’ than boards I’d used in the past (Raspberry Pi, Beaglebone Black). So I decided to do a little benchmarking.

Raspberry Pi Model B+
One day after launch, I got delivery of a Raspberry Pi model B+. Here’s a few pictures of it, plus a couple of side-by-side pics with the old Model B.
PiPhone – A Raspberry Pi based Smartphone
Here’s my latest DIY project, a smartphone based on a Raspberry Pi. It’s called – wait for it – the PiPhone. It makes use an Adafruit touchscreen interface and a Sim900 GSM/GPRS module to make phone calls. It’s more of a proof of concept to see what could be done with a relatively small form factor with off-the-shelf (cheap) components. I don’t expect everyone to be rushing out to build this one, but I had great fun in doing it, as it builds quite nicely on my previous projects, especially the Lapse Pi, a touchscreen time-lapse controller, and uses most of the same hardware.
