Re: Walkie-Textie Wireless Communicator
#62I'm backwoods camping next week, and we have 25 people spread out over three sites. I was thinking it would be funny to bring some old rotary dial phones and some sort of way of hooking them up, and then just have that as the intercom between sites for when dinner is ready or whatever. It's next week, so unlikely to happen and I'm not sure what technology I would need to make it all work. Something like Lora plus a w…
They did that on the last episode of Star Trek Strange New Worlds (rotary phones).

#63A question for folks who know things I don't: if I wanted my phones to work in an area without cell signal, for just me and my family, is it possible to build a "personal" cell tower that our phones would just connect to and work, and allow us to text each other? Or is there a whole layer of auth required for our various phones to actually be able to use a fake network?
Not really. This stuff is heavily NDA and patent encumbered. You’d be better off setting up a local wifi network and using an IP based audio call system.
I'm not sure if this applies to all carriers but with many carriers if you are on wifi you can send/receive text messages and sometimes even make calls. Certainly you could use WhatsApp or similar in that case.

DeviantOllam has a few videos on YouTube about some con/meetup thing he goes to that does just this. You might be able to get a few ideas from that.

#65> ATtiny814 Why do people still use these ancient chips?
The ATtiny814 is hardly an ancient chip. It's a member of Microchip's TinyAVR 1-Series that was released in 2017 and still being developed, with the 2-Series being released in 2020/2021.
Perhaps you're confusing it with the older ATtiny841 (released in 2012), which was an upgrade of the original ATtiny84.

#66It uses the slow method where you push the same key until you get the letter you want to show up? Does anybody remember T9? You push the keys for the letters you want and it figures out what you're typing from a dictionary.
Yeah I thought he was going to say it uses T9 too, but it uses an inexplicably archaic chip so there's no way you could fit a dictionary on it.
I'm lowkey shocked it's not a esp32 or something. I haven't seen a ATTINY used for a long time.

#67> ATtiny814 Why do people still use these ancient chips?
They're cheap, robust, readily available, super easy to develop for, have a well-chosen set of peripherals that can reduce BOM even further (e.g. the CCL)… what's not to like?
They have the same price and availability as Cortex M0 chips, are more difficult to develop for (8-bit AVR ouch), and seem to have a similar number of peripherals as any microcontroller.
The RP2350 is the same price and several orders of magnitude more capable for example.
Really though, how many of these is he making? 3? Cost isn't a factor.

Not if I'm in the middle of the woods with no connection to the outside world.

A couple years ago I stayed at an AirBnB and there was an old rotary phone in the kitchen. Unfortunately, I found it was merely placed there as an antique curio and wasn't hitched up with service. I felt a little cheated honestly.

Isn't this what Wifi Calling is for?
