Hackaday Editors Mike Szczys and Elliot Williams recorded this week’s podcast live from Chaos Communication Camp, discussing the most interesting hacks on offer over the past week. I novel locomotion news, there’s a quadcopter built around the coanda effect and an autonomous boat built into a plastic storage bin. The radiation spikes in Russia point to a nuclear-powered ramjet but the idea is far from new. Stardust (well… space rock dust) is falling from the sky and it’s surprisingly easy to collect. And 3D-printed gear boxes and hobby brushless DC motors have reached the critical threshold necessary to mangle 20/20 aluminum extrusion.
Take a look at the links below if you want to follow along, and as always tell us what you think about this episode in the comments!
Space is very much the final frontier for humanity, at least as far as our current understanding of the universe takes us. Only a handful of countries and corporations on Earth have the hardware to readily get there, and even fewer are capable of reaching orbit. For these reasons, working in this field can seem out of reach for many. Nevertheless, there’s plenty about the great expanse beyond our atmosphere that can be studied by the dedicated citizen scientist. With the right equipment and know-how, it’s even possible to capture and study micrometeorites yourself!
For those new to the field, the terms used can be confusing. Meteoroids are small metallic or rocky objects found in outer space, up to around 1 meter in size. When these burn up upon entering the atmosphere, they are referred to as a meteor, or colloquially known as a shooting star. If part of the object survives long enough to hit the ground, this is referred to as a meteorite, and as you’d expect the smaller ones are called micrometeorites, being on the scale of 2mm or less.
Stardust Proves Hard To Find
Being tiny and having fallen from space, micrometeorites present certain challenges to those who wish to find and identify them. In spite of this, they can be found by using the right techniques and a heck of a lot of hard work.
