Tweet your Candidate is back!

Following the initial joy and elation at discovering we’ve got yet another chance to express our electoral opinions I’ve updated TweetYourMP.com to now include candidate information for the forthcoming 2017 snap General Election, and I’ve even managed to secure yet another dot com – TweetYourCandidate.com includes the details of over 3,000 candidates standing in the 650 […]

Countdown to Christmas with the Arduino advent calendar!

This year, as part of the publicity for their Christmas charity gifts, Concern Worldwide (who I’m lucky enough to work for) commissioned an artist to come up with a design for an advent calendar. The resulting design by Robert Fiszer is really rather lovely (you can check out the campaign here)- and lends itself rather well […]

Official Raspberry Pi touch display review

This week saw the launch of the official Raspberry Pi display, so I thought I would write up a quick review to share some of my initial thoughts about the device. Ever since the first version of the Pi there’s been a DSI connector on the board – and although there have been lots of […]

Ryanteck Raspberry Pi Serial Debug Clip review

When building projects on the Raspberry Pi that run ‘headless’ I’ve often found it necessary to connect to the Pi to see what’s going on, work out why it’s not working as I expected or to simply shut it down neatly without yanking out the power cable. There are a few ways to do this […]

My aim being to build a hackable portable digital camera which hopefully would be able to capture images not possible with a normal digital camera, and […]

Cheap Raspberry Pi outdoor case

Here’s  a very cheap outdoor weatherproof case for the Raspberry Pi. I’ve been experimenting with the AirPi weather sensor kit (available on Tindie). This is a lovely kit which comes bundled with an air-pressure, humidity, light, temperature, NO2 and CO sensors. The AirPi is fairly easy to solder together and comes complete with some nice […]

Raspberry Pi LED scrolling sign

I’ve been playing around with LED scrolling signs for a while now and have been looking for an affordable sign to use for a project. Some LED signs are really expensive but I’ve recently come across this one from Embedded Adventures: It’s a 80×8 display with three colours – Red Green, and Red/Green mixed to […]

Add a Raspberry Pi temperature gauge to your blog

At the moment I have a Raspberry Pi sat in the kitchen at home, running a Ghost blog – you can usually find it a ghostpi.org (BT broadband connection permitting). As I don’t usually leave computers running 24 hours a day, 7 days a week I was curious as to how warm the Raspberry Pi […]
