Things to Make and Do

When I was a kid I had a book called "Things to make and do" which would appear on rainy days in the school holidays.

Over the summer I'll be trawling the web for Open Source things to make and do.....

Multi machine

You may have heard of 3-in-1 machine tools — basically a combination of metal lathe, mill and drill press. The MultiMachine starts there but adds many other functions. It can be a 10- in-1 (or even more!) machine tool that is built by using vehicle engine blocks in a LEGO-like fashion. The MultiMachine uses 6 unusual construction techniques to build 5 very simple “modules” that bolt to a worn out or broken vehicle or industrial engine block.

This heat pump, electrical generation project to design and build a system that uses a combination of direct and indirect solar collection to generate electricity and store thermal energy in an economical, environmentally friendly, scalable, reliable, efficient and location independent manner using common construction materials.

Make a Sterling Heat Engine.
There are many designs for Sterling heat engines on the web, any heat source will make these engines work including the Sun. Here's how they work
