Hello all!
Due to the recent statements by Google (as well as their track record the last few years) I’ve decided I do not want to use Android as a phone operating system anymore. But Apple is just as bad, if not worse. So I’ve decided to build my own custom device.
I am working on building a phone using a single board computer, right now I’m using the raspberry pi 5. This is still a proof of concept, but I want to share my ideas with others, so like minded individuals can start messing around with this idea in their own homes to further this goal.
You can view more images of the device here, as well as the step by step instructions here (these are still very rough and incomplete) https://github.com/muhammadmanwar/cheaphone OR https://codeberg.org/muhammadmanwar/cheaphone
Right now it just runs raspberry pi OS, with a different desktop look and feel. Everything that normally works in a pi 5 works on this device, additionally I am experimenting with a Mobile Broadband modem, to allow the device to text and call, as well as access internet, like a normal phone off wifi
The total cost is around 200 dollars, not including the 3d printer to make the custom case.
This project is barely off the ground, and I’ve got a lot to learn before I can stop relying strictly on the raspberry pi 5, my end goal is to custom design SBCs, and release those designs for free alongside the plans for the device, so that interested parties can select their own System on a Chip to use for the device. I need to get into designing boards, I’m interested in trying Stephen Hawes’ Lumen PnP (https://www.youtube.com/watch?v=JlkTcxh-9gA) for that phase.
But that’s for the future, for now, I’m hoping to get more people interested in the prototype so that I’m not the only one noodling around on this idea. I’d love some feedback, and if anyone was willing to put one together for testing, I would appreciate it greatly!
Let’s not forget all the software that was done and kinda ready for the openmoko device. There were a few distros for that alone. Some were pretty stable but the biggest issue came down always to phone call quality and connectivity. I’m completely out of the loop but back then all the chips were so closed in themselves that they were basically black boxes. A huge effort was made to try and get them to work as well as possible, with varying degrees of success. I wonder if it continues being the same nowadays.
The N900 was such an amazing device, I still have it around and the UX was the best I’ve had in a phone, Maemo was truly great and way advanced to its time. That UX with the screen sizes we have today… I keep dreaming.
Phone quality on my Pinephone is nice except when it isn’t. We have a largely Free Software baseband running on the modem. You can tell it to run a high samplerate and it does VoIP and 4G. On the flipside it doesn’t always work and there were issues with additional stuff like echo cancellation, which then takes away from the experience. Openmoko was great as well. I think it was so very open, people could do silly things with the phone network. But then it’s old tech by now and the 2G (GSM) phone network is obsolete and they turned off the cell towers in most areas by now. And I think the software on it didn’t really translate to the phone generations after that. Afaik the entire software stack didn’t carry over and we’re using different dialers, messengers, calendars etc now.
