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

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

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

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!
