I used to jog in 0F weather when I was young. Now? Absolutely no way. I have no idea how I handled it. It hits 15F and a search party has to be dispatched if I don't make it back from my mailbox.

Arduino is interesting. I have a Raspberry Pi that I am going to use as a controller for my next dollhouse build....I think. I want it to control the lights and sound synced to actual time of day. I'm not a programmer but I think I can muddle my way through it. I understand the GPIO interface well enough too. I'd like random sound events to go off like doorbell ringing and radio playing. That's a few months away though...plenty of time to look into it.
