3D Printing an Aston Martin

Ivan Sentch is 3D-printing a 1961 Aston Martin DB4 on his Solidoodle desktop 3D printer, 4 inches by 4 inches at a time. The Auckland, New Zealand resident is about 72% done printing the body, and he expects to pay a mere $2,000 NZD for the plastic to make the plug — versus the $12k–$15k for a CNC-cut foam plug, which is what is normally used in replica car projects.

Pedal Power: The Quest for the 100 MPH Bicycle

Pedal Power: The Quest for the 100 MPH Bicycle

England’s Tom Donhou makes some beautiful hand-built road and mountain bike frames. He got the idea to put his handiwork into action build (and pilot) a bike that could reach 100 miles per hour on the flats. Working in his shop and with England’s Royce he build a rocket of a bike with a monster front chain ring nearly as big as his wheels. !He was inspired by the homebuilt cars roaring across the salt flats of Utah. There are no salt flats in the U.K. so he choose a two-mile WWII-era runway. But his quest didn’t stop there. The short documentary below documents his efforts and those of his collaborators. It’s a great story of ingenuity, daring, and the maker spirit.

Maker Hangar Episode 5: Servos

In Episode 5 of Maker Hangar, Lucas Weakley teaches us about servos, these are the little motors that move the control surfaces on RC planes. We learn about the different parts of a servo, and what each of them do. We see how to classify servos by their sizes, weights, and strength. Lucas also goes over the different types of linkages and the techniques on hooking up control surfaces.
