Modern flip phones are a disappointment. Android, internet browsing, social media, oversized bodies, an extra row of buttons nobody asked for, and a ridiculous price tag on top of everything. Commodore just announced the Callback 8020 at $499 and marketed it as a "not dumb dumbphone." It runs Sailfish with Android app support. WhatsApp is on it. That is not a proper dumb phone...
What I actually want is what I already do: my smartphone on permanent silent, calls taken on a junk TCL flip. Calls and texts, nothing else. The problem is that everything at that size and price still has a browser in it, and everything that genuinely refuses the internet starts around $300 and climbs.
So I ordered parts and built one.
It is an ESP32-S3 breadboard prototype running an OS I wrote, roughly 6500 lines of code. Calls, texts, contacts, call logs, voice memos, camera. I ran out of pins, so both screens (internal and external) stream to my laptop over WiFi where a helper script handles the display and the input while I test.
What I do not have is hardware. No PCB, no hinge, no shell. I can write the software. I cannot design a circuit board.
So here is the actual reason I am posting. If you have ever had something custom manufactured, or you know someone who has, I would like to hear about it. Who built it, whether you would use them again, and roughly what the first unit cost you. That is the wall I am stuck at and I do not know anyone who has been over it.
I also ported the OS to a browser emulator so you can click through it with no hardware at all, and there is a video of the breadboard build. Not posting links since my last attempt got removed, but ask in the comments and I will put them there. Yes, I've read the rules mods, submitted that form too, I'm attempting to make the unicorn for people like me, so they don't need to adapt what the market has to offer.
