Mowing season end

In 2018 the automower worked for 516 hours. By October 2019 the count is at 960 hours, so it has worked 444 hours during the 2019 season.

The outer shell is removable - so all the grass clippings can be cleaned off...

Time for a winter break, back to work in May 2020.

Iltarastit Paloheinä

The last Iltarastit event for this year. A bit wet in the forest after all the rain lately. I did have my garmin-watch but it somehow managed to forget this run completely - so a hand-drawn route instead.

uBlox F9T qErr correction

Here's a test of how to correct the 1PPS signal out of an F9T with the qErr-value from the UBX-TIM-TP message.

When the time-interval-counter is configured with start=reference-clock, stop=uBlox, the qErr is applied with a + sign to the measured time-interval - resulting in much smoother data for averaging times up to tau=1000s.

Firmaliiga Salmi

warm, over +20C. My Garmin watch didn't get a GPS-fix at the start and it took until #3 for it to start recording.

No major mistakes but not so great running/fitness.
