WTF with DAB radio and its clock after daylight saving time shift
I don't know why, but last sunday, when local time changed from CET to CEST weird thing at one of local DAB multiplex happened. The time was not +1h shifted, as is normal when changing from CET to CEST, but it shifted +1h40m. AFAIK only one DAB multiplex is affected by this issue.
I ran into a huge disaster when I decide to help my friend to build a Velleman's blinking christmas tree kit. It was claimed as easy to build kit for young children, so what could go wrong? Everything! Eight hours! Eight hours of pure mordor fiddling the small LEDs into exact positions to build a christmas tree picture. Terrible experience! No more please, but the result wasn't so bad. I have about 40 yrs of experience with soldering iron and this "thing" took me 8 hours to build!!! In my opinion it's almost impossible for young children to build this in some decent looking way, which is something, that must lead to a great frustration.

Vrátil se mi energomonitor/wattmetr Silvercrest v poměrně neradostném stavu. Ve videu tvrdím něco o přestavbě, no nakonec to stačilo jen vybrousit. Každopádně je to děs. (Video ze zrušeného youtube kanálu.)
Simple blinking Christmas Star you can build. Hardware/software is also usable for another pseudo-randomly blinking things.
