The Raspberry Pi-powered loom

We’re a small organisation full of makers, and I think at least two of us own a hand loom for weaving textiles. (One of the reasons I enjoy the TV show  Vikings so much is the casual looming that’s going on as backdrop in many of the indoor scenes – the textile sort, not the impending-doom sort, although there’s plenty of that too.) Siggy and Laergatha (personal role model) get down to a spot of light weaving before commencing to crush skulls and pillage. Here in the 21st century, Lorna and I use hand looms because powered looms are very expensive

Photocatalysis with a Raspberry Pi

Access to clean, safe drinking water is a global problem: as water.org notes, 663 million people lack access to water that’s safe to drink.

Guest post: A Pi lab in rural Ghana

Liz: This post comes from Heather and Trevor Grant, who work with a student-led charity called The Best of Both , based at the British School of Brussels. Thanks both!  For the past five years The Best of Both initiative has worked with state-sector rural schools around Bolgatanga in the Upper East of Ghana to help improve access to water, food – through school gardens – and educational resources (books and access to ICT).

Guest post from Khan Academy Lite

Liz: We’ve been talking a bit about Khan Academy Lite on this blog recently. KA Lite is the offline version of Khan Academy, and we’ve recently seen the Kingdom of Bhutan’s first Raspberry Pi being used as a server to give kids offline access to the huge, free suite of Khan Academy’s top-quality video lectures and learning materials. You can read more about Khan Academy on their own website , but don’t just take their word for it: there’s a wealth of material online about the Khan Academy learning experience from users, if you have a few minutes to google for it
