I plotted a bunch of UV snowflakes. I keep giving them away so I needed to rebuild my stock.
I hand them out to kids with a super cheap UV LED. They love it and then they shine the light everywhere else searching for reflective surfaces. It’s much like playing with a magnet where you try to discover where it will stick.
Hey psssst, kid, you want some snowflakes? I got some sheep too.
We’ve gotten quite good at managing the heat in the house. On super cold nights, we used to wake up a few times a night to keep feeding the fire, this is no longer the case. I rebuilt the house temperature Pi which got borked and I never fixed, I’m curious to compute the variance in house temperature from early years to now.
