Pontlottyn

Here I am at a climbing wall in Bristol, having balked at the price and instead sat in the cafe. They ought to have a discount rate for people don’t actually like climbing. Here’s what I enjoy instead. (I am so predictable):

Brrr, it was cold in grimmest South Wales on a grim Saturday when all the colours are grey and the light makes everything flat. I enjoyed a sublime hour long flight above Pontlottyn, even though I didn’t go anywhere except soar up and down the ridge alone and then top land in a howling gale.

My box of tricks is in the 3D printed purple box on my left next to the airspeed indicator. I’ve not had the chance to do anything with the data except plot it and go: “that’s pretty noisy” at the accelerometer data. I have plans to extract consistent correlations, barometer vs altitude vs temperature, bar position vs wind speed, roll angle vs turning rate registered on the compass, and whether I keep diving out of turns because I don’t have enough speed and control.

Unlike my so far doomed attempts at manipulating house and fridge temperature data, this flight dynamical system is memory-free. The same temperature, pressure, windspeed, and wing angle at any time of the flight should result in exactly the same response. Deformations of the wing are brief and temporary. This is not the case for the fridge where every cycle begins with a different temperature distribution within the dense cabbagy foodstuffs and chemical pumping machinery.

Subject to instrumental noise and turbulence, all the data should be with me, and I can only hope this isn’t going to end up as just another one of my expensive failed software projects that looked plausible when I began, but then crash landed in the trees.
