  • Here’s the thing, datacenters could be powersipping butterflies if they built solar farms and ground source heat pumps when they build out the data centers. But the Epstein class are too cheap, greedy and selfish to do that without being forced to. They are accustomed to having the government, directly or indirectly, lower their costs and guarantee them profits.

  • It took me decades to finally figure this out. It wasn’t until I started building solar systems and batteries that I realized what was happening.

    You can have the same issue with rechargeables, but they are more resilient. Running them in parallel will work fine because the batteries balance out their state of charge. When you run them in series they have no way to balance out and one is always dragging the rest down. If the difference is too much then that lowest battery heats up considerably. That cooks the electrolyte.

  • This won’t happen if you are constantly using the remote and batteries,

    It still can. I have found that the most common cause of batteries going south like this(when being used actively) is when there is a voltage mismatch between the batteries.

    Always make sure you use batteries from the same pack when you put them together in a device. That or get a voltmeter out and check to make sure their voltage is the same.

    This is less of an issue when the batteries are in parallel, but almost all cases where batteries are combined in electronics, they are putting them in serial.

  • Oh yeah, I’ve got a box of esp32s and mmwave sensors waiting for me to get my soldering iron out. I’m with you, they’re great. I suppose I could somehow figure out out how to do SDR with an ESP32, but I’ve got plenty of unfinished projects waiting for me as it is. ESPHOME makes edge devices so easy to create. And it gives me an excuse to do a little soldering and 3d printing.

    The ESP32s are also really good for making old devices smart. One project in my queue is turning a bunch of air purifiers into smart devices that HA controls. They were super cheap and there’s nothing to them but a fan, and a filter but they’re loud. I’m going to make it so they only run when no one is in the room.

  • I was thinking the same thing. My path was self hosting on old desktops for the longest time then the pi came out and I ended up doing a birdnet project, then home assistant and now I’ve got about a half dozen data collectors on pi zero 2 w machines. They are pretty much set and forget. I use an orange pi for my instance of Solar Assistant because I wanted something that was not affected by anything but the network and the inverter and I know how rock solid these little machines are.

    But in the last few years I’ve started embracing docker and NUCs and have pulled apps off Synology, making it just a file server at this point.

    So technically I have more raspberry pis than anything else but they are really just edge devices, except for Home Assistant. And it will probably stay that way until there is a good reason to switch. I don’t see that happening for years.
