How to Make an Adult Soapbox Kart

“This guide will teach you the basic aspects you’ll need to consider to make yourself a road-worthy gravity-powered vehicle. Full suspension on gokart wheels, driver restraints, a ridgid frame with roll bar, and balanced drum brakes are features of the example kart I’ve built that weighs in at under 100lb.”

Of course, this thing only works downhill and is useless as a practical means of transport. But could we please get rid of the Indy 500 and the Formula One circus and race these karts instead? Seems like a lot more fun to me. Previously: DIY replicas of 1930s race cars.

DIY Book Scanning

Diy book scanner “Do-It-Yourself Book Scanning is using cheap, compact cameras and free software to scan books quickly and efficiently. DIY Book Scanners can be as simple as a camera and a piece of glass [PDF] or as involved as the Instructable that brought our community together [PDF / Vimeo]. We’ve come a long way since then. We have GPL-licensed laser cut designs, aluminum designs, and detailed instructions for beginners. We have built hundreds of scanners and freely shared thousands of design improvements.”

How to Build an Earthbag Dome

“Domes are the strongest form in nature and easily support enormous forces. They create the most floor space for a given length of wall. There are no wasted corners. The feeling inside is magical. Those who live in domes (and roundhouses) most likely never live in boxes again. Wind flows around domes and does not build up pressure against them.”

“You can build domes without wood. You can build domes with minimal tools and materials – no nails, no wood, no plywood, no shingles. This makes domes a good candidate for those who lack carpentry skills and for emergency shelters for disaster areas and war refugees. Give people some rice or grain bags and a little training, and soon they can build their own sturdy, safe shelters.”

Compendium of Useful Information

“Access to 2 gigabytes of information about sustainable and resilient living that meets the challenges of peak energy, climate instability, economic irrationality, toxic politics, war and violence.”

Compendium of useful information – version 1.0, september 3, 2010. The page reminds a lot of the 13 gigabyte database set up by Alex Weir (previously: How to make everything yourself – online low-tech resources), and from a quick overview I learn that many of the same sources are listed.

However, the list is better organised and also seems to contain quite a few DIY-resources which I did not see before.
