Antikythera Mechanism

Travel back in time 21 centuries and create a machine that not only shows the position of the sun & moon as well as the other planets in the sky for centuries to come, but also predicts solar eclipses as well. And do that before before the invention of the modern gear. More info: World’s […]

Desktop Foundry

Great step-by-step directions on how to make a desktop foundry. Using scrap wood and Sugru, you will be able to cast small figurines and minatures. What makes it all possible is a special eutectic alloy, Field’s metal, which melts at an amazingly low 144°F (about the temperature of hot coffee). Unlike other low melting temperature […]

100s & 100s of hours for what?

“100s and 100s of hours of work to create…” something that sits on your desks and pretends to look around. Seems like CNC is the way to go if you want to build crazy stuff like this or the orrery. But if you watch the video you’ll realize that with any machining you will spend […]

Building An Orrery

This is completely drool worthy! Ken Zeamon details his plans and procedure for making an orrery. He even  has a downloadable file with the files for his CNC Sherline mill. Lots more detail and videos here: Via CNC Cookbook via make:blog My favourite part is the 7 months in 7 minutes video because it helps with […]

507 Mechanical Movements

There are those people who meticulously read books from beginning to end, then there are those who go through them with a fine tooth comb and try to recreate every single device in the classic book 507 Mechanical movements. I love those people! So Yeah! to Matt Keveney who did that very thing on his site
