If you’ve been wondering what was happening with Aerolab lately, here’s the scoop. I’ve been at work developing Chung-On-A-Stick, a planar velocity sensor for doing virtual elevation work. It’s involved a lot of time, some extremely good friends, and a few dollars but things are finally coming together nicely. With any luck, we’ll [...] As GoldenCheetah prepares for its upcoming release, I wanted to keep you all posted about the development of the virtual elevation module, Aerolab. Aerolab is not currently in Golden Cheetah, but I’m hoping it may eventually find its way there. There’s tons of work still to be done, but at least we [...] The method of Virtual Elevation and all its variants are derived from Newton’s 2nd Law for linear motion, neglecting rotational inertia terms. Do those additional terms play a significant role in elevation-matching? Can we accurately measure the moment of inertia (MOI)? In this post, I’ll describe the terms and provide a [...] A recent discussion on the Wattage Training Forum got me to hack the VE code to quantify the difference between the exact and small-angle version of the VE calculation. The columns of the resulting CSV file are as follows: SAMPLE #: row index The final [...] In trying to create a prototype for Golden Cheetah, I put together this perl script that I submit for your perusal. The script comes with the sample data used by Robert Chung in his recent post to the Wattage Forum, so it may look familiar to many of you. My aim was to match a known [...] |
