# Hackaday Podcast 160: Pedal Power, OpenSCAD In The Browser, Tasmanian Tigers, And The Coolest Knob

Join Hackaday Editor-in-Chief Elliot Williams and Managing Editor Tom Nardi as they tackle all the hacks that were fit to print this last week. Things start off with some troubling news from Shenzhen (spoilers: those parts you ordered are going to be late), and lead into a What’s That Sound challenge that’s sure to split the community right down the center. From there we’ll talk about human powered machines, bringing OpenSCAD to as many devices as humanly possible, and the finer points of installing your own hardware into a Pelican case. There’s a quick detour to muse on laser-powered interstellar probes, a Pi-calculating Arduino, and a surprisingly relevant advertisement from Sony Pictures. Finally, stay tuned to hear the latest developments in de-extinction technology, and a seriously deep dive into the lowly nail.

Hello! For whatever reason I had a lot to say after this week’s episode, so here they are:
First thing is that us in the American south got a Saharan dust cloud a while back, all the way from across the Atlantic. No interference with gadgets except some bad radio signals and some amazing sunsets. That’s 2020 for you, I guess.

I’m not sure how aware the general public is of this, but cyclists normally measure our power output in watts (or, if you’re Robert Forstemann, kilowatts :). Bike power meters are quite interesting, and you don’t have to be a seasoned pro to use one – or make one. One of my favorite analogies for voltage and current are the two metrics that cyclists pay attention to on the more athletic side of things (cadence = voltage, power = current). This came to mind when you were talking about controlling the power output of a stationary bike, as a cyclist must control his power output and cadence with the transmission. The load (like the phone’s 5W or charging the SLA) is sort of analogous to the incline on a real bike, if we follow the analogy from earlier.

All of these thoughts are completely authentic because I had them while listening to the podcast on a bike ride :)
