I decided to log the mains grid frequency for a full 24hr period 🤷🏼‍♂️🤓

Using the Philips PM6669 and an external OCXO (calibrated, see earlier post when I received it) I get a quite accurate result. Each measurement takes 10 seconds, so in reality there’s some averaging going on right there, removing some of the jitter and noise at those last digits. The grid frequency is highly dynamic once you reach a millihertz resolution, and that is in fact what I’m trying to capture 🙂

The PM6669 counter has a really nice feature btw., it’s max input level is 260Vrms! That’s really handy, in reality I could connect it straight to a mains outlet without damaging it, but due to the risk of transients I’m using a small transformer and the cute little Vellemann oscilloscope training kit so I can pick a more safe 12Vrms instead 👌🏻⚡️🙂

Tonight I’ll have 8640 datapoints to play with 🤓

Olen nyt tehnyt päätökseni.

Olen nimittäin parisen tuntia pohtinut tehdäkö ruokaa vai tehdäkö vohveleita.

Jälkimmäisiä on tehyt mieli jo pitkään, mutta tekeminen on jäänyt, koska maha täyttyy joka moinen päivä riittävästi ruoasta.

Tänään lähden liikkelle siitä, että teen a, ja jos tuntuu, että mahassa on vielä tänään tilaa, teen myöhemmin myös a.

Aikuisena voi tehdä tällaisia päätöksiä.

Lapsena ei.

A blend almost a year in the making. Two to one mild to old ale. The brett is slightly tamed. The malt sweetness is transformed into dark toffee. I love it.
