Perseverance – the Making of a Parachute

09/03/2021 Tim Beard

I was inspired to create this dashboard by the amazing videos of NASA’s Perseverance Rover surviving the “Seven Minutes of Terror” during it’s landing on Mars. If you saw it, you probably noticed that the parachute had a rather strange pattern on it. It turns out that that was one of many easter eggs included in the mission. The parachute encoded the Jet Propulsion Lab’s motto “Dare Mighty Things” along with the coordinates of the Lab itself. “Super nerdy”, I…

Making waves with Fourier Series, Part 3

17/08/2020 Tim Beard

This is the third in my series about how I built my animated dashboard about Fourier Series: By the end of the last post, I had built up the SIN wave graph (bottom-right in the dashboard) and the waterfall chart (not visible above). In this post, I’ll go through the steps for creating all of the elements in the main graph at the bottom of the dashboard, which I simply called “Circles”. The components of this can individually be turned…

Making waves with Fourier Series, Part 2

14/08/2020 Tim Beard

This is the second in my series about how I built my animated dashboard about Fourier Series: Seeing the SINs The basis and indeed the whole point of the dashboard are the calculations needed for the SIN graph. Here shown for the square wave: The whole idea with a Fourier series is that different SIN waves, all at different frequencies and amplitudes according to the equation below, add up to form a square wave with an amplitude of 2 (-1…
