If fire wasn’t the first thing invented, it was probably the second. The human race has had a long relationship with fire, and now you can use it to charge your smartphone, GPS, or anything else that you can connect to this thermoelectric generator using a USB cable.
Here are some helpful pointers on measurement to help make sure you do it correctly.
Youtube user QueticoChris uses an old cast-iron flywheel and vintage building techniques to design and make an efficient foot-powered wood lathe.
This mechanised solder dispenser was built by design engineer Jude Pullen, as an example of what could be done using ABS plastic sheeting, a broken brake cable from a bicycle, and some Sugru.
Christian Carlberg is a Cornell-educated mechanical engineer. After his undergraduate degree, he spent three years doing classical aerospace work and getting an MS, part time, at night school. At 25 he moved to LA to work in movie FX, specifically “practical effects”—physical, animatronic robot-based puppets now in decline thanks to low-cost CGI. After that, he […]
It’s remarkable how the MIT Hobby Shop presages aspects of the hackerspace movement… In the 1937-38 academic year, Vannevar Bush, then Vice President of MIT, granted a group of 16 MIT students permission to use a room in the basement of building 2. With equipment they found around the Institute they set up a wood […]
Inspired by FLIR Systems scientist Austin Richards’ recent book, “Alien Vision,” I decided to see if I could put together my own imaging-based tour of the electromagnetic spectrum using web-based resources. This post is the result. Here are 17 striking images from across the spectrum at wavelengths ranging from one meter down to one-trillionth of a meter, from radio waves to gamma rays, arranged in order of increasing frequency / energy. Each is accompanied by a caption identifying the instrument used to record the image, the approximate wavelength at which it was recorded, the subject, and a link for those seeking more information.
