That was actually one of the things I was interested in as well. The pi 5 comes with two micro hdmi ports, which allows the device to be plugged into a monitor and used “as a desktop”. You can even have the device propped up next to the monitor for a dual monitor experience. Some people already use a pi 5 for web browsing or document editing. I can easily imagine people using a single device for both personal home PC use as well as on the go computing and calling, and only having a dedicated device at home for heavy gaming or potentially home server use.

50mmx130mmx82mm I measured it in freeCAD, so it might be a few millimeters off the real thing

I don’t necessarily disagree with you. And people do seem excited about the concept. I’m not even sure I’m far enough along to justify taking in donations though. So far I feel like all I’ve done is compile information that’s already available online into one document. I appreciate your perspective

Sorta copying my comment from another response, but it may answer your question as well: Right now I’m using this “Gravity: CAT1 A7670G Global 4G IoT Communication Module”, connected through USB-C https://www.dfrobot.com/product-2802.html I am able to text reliably using a chat software (it came preinstalled with gnome or KDE, not sure which), and connect to mobile data unreliably using ModemManager and mmcli. I haven’t been able to make a call yet, but I think this is due to a software issue, I’m still trying to get everything working reliably. Once I figure out how to do all of these things reliably, I will add it to the guide in the repo https://codeberg.org/muhammadmanwar/cheaphone

Thanks for the suggestions! I’m not actually looking for any donations though. It probably sounds weird, but I don’t want to derive value from this, or even assign value to it, in the interest of keeping the information as freely accessible as possible. Not too get too ideological, seeking money often causes people to make a good idea bad, or to make a simple process inefficient, to make more money from it. I’m thankfully in a position where I can keep (slowly) working on this project in my free time, while still keeping my head above water.

That isn’t to say that no one else should make money from this idea. I just don’t want to personally.

I do like the idea of a copyleft license. I’ll have to look into it a bit more. Thanks again for your suggestions!

I’m not sure how to add more images to the post, sorry. But I uploaded images to a repo, in the pictures directory. There are also step by step instructions to make one yourself! https://github.com/muhammadmanwar/cheaphone OR https://codeberg.org/muhammadmanwar/cheaphone

This is definitely the angle I’m trying to work. The more people who know how to build these sorts of devices, the more software and hardware will be supported, and standard custom software/hardware pairings can be documented. But we won’t know what works till we try it

Wow! That does seem really similar to what I’m doing. And they seem further along than I am. I’ll have to look into this project some more. Thank you!

This is a very helpful suggestion, thank you! I have been having some issues figuring out spacing, the battery sticks out like a sore thumb right now, so if this can save me some space I may end up moving in this direction for further prototyping. Thanks!

Thanks for the suggestion, I mirrored the repo here: https://codeberg.org/muhammadmanwar/cheaphone

I may end up switching entirely to code berg, but I’ll see how bothersome it is to push changes to both before I fully migrate. Thanks again!
