Calculating rpm from pulley sizes is not likely to be accurate because the effective diameter is rather indeterminate especially for small pulleys. If you can't get hold of a 'scope to look at the waveform you might try listening to the output via a suitable step down transformer and loudspeaker (or...

Agreed about the black boxes but new shiny (or grubby in my case) cars have a much lower failure rate despite their increased complexity and electric ones should be even better. In the last 15 years or so - excluding one accident and yjr odd puncture - I've only had one incident needing assistance (...

Its not the 'newness and shinyness'. Its the reliability and backup. Many of the offerings on the market (no disrespect to other posters!) are here today and gone tomorrow when something goes wrong.

Our 60A supply has survived 6 years so far and doesn't get noticeably warm under heavy loading. We have overhead distribution and the only way they could/would increase our supply was to add an additional 60A via a separate underground cable - at a high cost and with me providing the duct under the ...
