Damp-Pi – Room Moisture Extraction with Raspberry Pi

20150824_165453bOver 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

IMG_1343 copyI 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

800px-CI20_perspectiveI 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 »

3D Printed Raspberry Pi Model A+ Case

 

IMG_1123The 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+

IMG_1121The 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

IMG_1053 copy2

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.

IMG_1062bRecently 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+

PiPhone – A Raspberry Pi based Smartphone

IMG_0872cHere’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.

Adafruit Led Ampli-Tie

Just a short post this time. When I saw this project on the Adafruit Learing System (learn.adafruit.com), I thought it was so cool that I had to build one myself. It’s a sound-activated LED tie!

There’s a great tutorial here: http://learn.adafruit.com/led-ampli-tie,  so jump on over if you want to see how it’s made.

Just for kicks, I did a quick 28 second video of it in action. I can’t wait for the next hackerspace / coderDojo /  work night out :)
