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, […]

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 […]

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, […]

Lapse-Pi Touch – A Touchscreen Timelapse Controller

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.

Lighting Foregrounds in Night-Time Time-Lapses

Here’s a quick hack to make your night-time time-lapse sequences a bit more interesting. As a general rule of thumb, it’s always good to have a decent foreground in your landscape images.

Website Downtime

Sincerest Apologies for the downtime over the last week. My hosting provider was doing migration of a bunch of websites from one server to another, and in this process they were upgrading MYSQL, Apache, plus a whole host of other stuff it seems.

Pi-Rex – Bark Activated Door Opening System with Raspberry Pi

(DISCLAIMER: Not meant as a security solution or a lesson in good dog behavior. It’s an experimental proof of concept to play with the application of embedded computing to solve particular use cases) Sleep deprivation has been driving me mad recently. And it’s all down to a new member of the family (kind of), our […]
