That's similar to the iFixit iron, as is the less expensive Pinecil.
Those are probably the best options currently available, but I want something more compact and self-contained.
I would not want multiple cells for reasons of ergonomics and convenience.
I probably don't need 100W for most field soldering. 60 is plenty, and temperature-controlled soldering irons usually don't need to pull high current continuously. It would need 60W for maybe 10 seconds when powered on, and when heating something large. The rest of the time, it takes relatively little power to keep the tip hot.
What I'm describing is, of course not the right tool for production soldering. It's for field work.
Assuming the M12 CP1.5 battery pack, it's probably three 18650s. Specifically, it's probably three LG HB series 18650s, which handle high burst loads well, but hold only 1500 mAh. A single Sony VTC6 holds 2/3 the energy of one of those packs. Wait... why am I speculating? Youtubers tear down power tool battery packs on video all the time, and someone did that one. They're Samsung 15Ms, which are a little worse than HBs.
Anyway, short runtimes are fine for most field repairs, which is the whole point of something entirely self-contained. Spare batteries can extend it indefinitely, but a battery soldering iron is probably not what I'd pick for extended soldering sessions.
I would accept a bit of an awkward balance for being self-contained.
Since 2014, but Android had already been out for six years at that point.
What I want from a battery soldering iron is a field-replaceable 18650 in the handle, not Webserial.
As a practical point, saying it in English will almost certainly communicate what you need to communicate. Almost everyone who makes international calls will recognize that you're speaking English even if they don't understand what you're saying, which suggests that the Russian or Korean speaking person they're trying to reach is not at that number.
We had several years of Android that mostly wasn't. Now it's hard work to get Android that isn't.
Apps on F-Droid are not using proprietary Google APIs and won't be affected.
The whole tech world saw Microsoft Palladium as a nightmare scenario, but was quiet ten years later when Apple and Google did the same thing to our phones. That was a mistake.
I understand why manufacturers did it; it bought them a bit more space.
I don't. New phones are huge while older, much smaller ones somehow found room for the analog audio jack.
Lemmy thread and link.
Basically, anyone who can read your home directory could decrypt your Signal database. That's about typical of traditional desktop applications, but questionable for security-oriented software. Mac OS and (sometimes) Linux have more robust credential management options, and Signal signaled (yes, pun intended) its intent to adopt them.
