  • There aren’t, really. There are a few antiques and half baked things.

    A big problem is that these days, unless you’re the size of Apple or Samsung, it’s impossible to get a reasonable hardware soc and modem other than one which only runs a soon obsolete blob laden android which is going to be EOL before you’ve even finished your design.

    The hardware is not there. The firmware/hw data/platform isn’t there even to begin OS work with. And there’s a global shipping, regulation and mobile operator hell waiting on the other side. And a product lifecycle that’s only a few years long.

    Yes, I’ve worked for phone manufacturers.









  • The Ender probably wasn’t. It was a lot of effort, and mostly not the interesting kind, and fairly little reward. Although when it worked, it was really good. In the end. Sometimes. And it’s way too big.

    The Kingroon, very much yes. It’s cheap, kind of trashy, but compact. Just prints stuff. Parts detach great. Works just about every time. Quiet out of the box. Just kind of annoying to preheat at the start and end of the session to load and unload filament. Very annoying touchscreen. But those are minor things and I’m not tempted to fix it or upgrade anything. I have actual projects to do. Too many actual projects to do.

    Oh, and why? Custom parts that are impossible to buy and a lot of work or impossible to machine or fabricate otherwise. Saves a trip to the local library or hackerspace or wherever things could be printed.





  • NiCd and NiMH batteries die when left in slow drain devices as the first cell to go empty starts to be reverse charged. These die and often leak pretty fast and you see that all the time if you repair old devices.

    Li packs don’t go empty as the battery protection circuit cuts the slow drain when they reach low water voltage. They are revived when the protection mode charge reaches low water mark again. They’ll be fine unless you leave them for years and years. Even then they generally never leak.
