This DIY Bipedal Robot Used Pneumatic “Air-Muscles” Instead of Motors

In 1987, Richard Greenhill, a British photographer who was fascinated by (but had no actual training in) robotics, decided he wanted to build a life-size humanoid that could do useful things, like carrying luggage. He was working at a startup called Intergalactic Robots, but he…

Explore the Stratosphere With a DIY Pico balloon

There’s an interesting development in amateur ballooning: using so-called superpressure balloons, which float high in the atmosphere indefinitely rather than simply going up and up and then popping like a normal weather balloon. Superpressure balloons can last for months and…

See the Sky Like Never Before With a DIY Eyepiece

When it comes to viewing nebulae, galaxies, and other deep-sky objects, amateur astronomers on a budget have had two options. They can view with the naked eye through a telescope and perceive these spectacular objects as faint smudges that don’t even begin to capture their…
