  • I guess my worry was that they wouldn’t be dry by the morning.

    I wash my feet before going to bed, and I have a second pair of socks that I only wear at night (when it’s cold, otherwise none).

    Like I say, if I had to go more than two nights, I’d have to figure something else out. Maybe two pairs of hiking socks, so one has 36 hours to dry instead of just 8 or 10.

    That’s actually not a bad idea… I could do that now for little effort 🤔












  • I was all geared up to make my first solar node, got a rak and a solar panel, put an 18650 in it. I was doing some testing to see how long it would last on my bench without sun. I got distracted and the voltage got lower than the rak liked, and then it just… Never came back. Wouldn’t wake up again, not with solar power or adding additional external power. I’d probably need to disconnect and reconnect the battery. But I never tried that, because the point was that I wouldn’t be able to.

    Before this, I had already been researching and thinking about different methods, and I had already wasted some money on some ill-planned hybrid lithium capacitors. I also had some disappointing range tests from the local hill. Plus I was trying to get my buddies on board and they were dragging their feet.

    So this was the last nail in the coffin. You can’t have a device enter a non recoverable state when it’s 40 feet up in a tree at the top of the tallest hill in town. Just bad design.

    That stupid thing is still sitting on my desk, almost a year now. I lost all interest, unfortunately.

    I’m sure I’ll come back to it, eventually.

    But yes, in my experience, rak doesn’t like low voltages, and will likely get stuck in an unrecoverable state.
