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
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
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.
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.
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.
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.
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
So here’s my latest Raspberry Pi project. It uses the PiTFT Mini Kit, which is a 320×240 2.8″ TFT display and Touchscreen from Adafruit Industries that fits neatly onto my Raspberry Pi, to control a user interface to drive the back-end time-lapse script I showed you in a previous blog article.
