This may say more about us than the current state of the telephone network, but unless your Grandma is still kicking, how many phone calls do you take that are actually worth picking up? Around here it’s one variety of scam or another, with the odd cold-calling salesperson to round it out.
So when we saw [Bolan Xu]’s texting-only TERMINUS cell phone project, it took but a minute to decide that, yeah, we wouldn’t miss the telephone part of the phone very much either.
The trade-offs are immense when compared to your smartphone; there’s no voice, no web browser, no social media, and no camera. But on the flip side there’s also no spyware and no annoying spam calls. Besides, he’s built a QWERTY keyboard onto this thing, and that does seem to be what most of us miss in this era of black rectangles.
In terms of electronics, its rocking a tiny OLED display for you to read your messages on, driven by an ESP8266. When WiFi is available the plan was to bridge over the internet in an SMS version of VOIP, but [Bolan Xu] ended up installing a cellular modem in it anyway.
As you can tell from the skeletal case, this is very much a prototype, but it is a promising project. We’ve seen ESP-based phones before, but they tend to be a bit smarter, and run on ESP32 instead of the more modest ESP8266.
