    that's some tough stuff to get your head around, thanks to past dave I already had a cheat sheet :)

    It get's worse from each iteration :D I was quite embarrassed when me and my mum pulled out the hotglue gun... looks a bit like Lukes Lightsaber training ball. I started a collection on thingiverse for inspiration of the next one https://www.thingiverse.com/deefdarko/collections/led-star

    So I thought that my LiPo Chargers in form of 4056 modules are all weird, broken and not powerful enough, until I've noticed that my UNI-T UT61E multimeter isn't calibrated anymore(?)! Stupid me also calibrated other stuff like my Power Supply made from a buck down converter and a notebook PSU using that meter. I also thought my R8D8 power bank was off big time and the batteries were done, because I've continuously measured 3.8V on each cell with that multimeter... meh. Cheap multimeter now tells me I'm stupid. meh. 

    Anyone any tips for voltage references? Or how I can recalibrate voltage without another multimeter?

    [update] I've seem to programmed all my attiny13 for #FLUX capacitor trinket with 13V instead of 12V, thanks to my multimeter... meh. but hey, they work.
