Notes from the recent eclipse: 1. When shooting the sun directly (I used 300mm and a Vari-ND filter) ensure the exposure is low enough to see sunspots – and then double check it. I had the correct exposure but bumped the filter ring and can’t see sunspots in the image sequence. 2.  If the eclipse […]

I was getting unusual data from the DS3231 clock, but I couldn’t tell if it was my wrapper or the original […]

Most classes have private and public members, but in the case of ‘time’, it needs to be accessible to other libraries, like logging and scheduling. […]
