You Can Build This Raspberry Pi-Powered, 4G Linux Phone
Building your own desktop PC is easy, but if you want a phone, you usually have to settle for a sealed box made by one of the big few companies.Maker Evan Robison uses the open-source Raspberry Pi our phone (opens in new tab) OURS acronym for Open Source, Upgradable, Repairable Smartphone.
According to Robinson, the idea was to create a smartphone alternative for people who wanted to control their privacy. So an open source solution was the best fit. The OURphone project includes quite a few features found in many smartphones, including 4G LTE Internet support, GPS support, Bluetooth and WiFi capabilities, and basic phone operations like calling, texting, and saving contacts to your address book. There are specifications. .
However, instead of running on Android or iOS, the phone uses the Raspberry Pi OS. This is a Linux-based native operating system for Raspberry Pi. This means that you have very fine control over what software you run, but the UI (as in the picture) isn’t particularly touch or phone friendly. instructions) can be found here: GitHub.
In his build guide Robinson uses a Raspberry Pi 3 B+, but there’s no reason why you can’t upgrade to a Pi 4. He comes with a 4G HAT with GSM and GPS antennas. For video output and user input he has a Waveshare touchscreen. A camera can be attached, but is not required for the build. Headphones with built-in microphones are used for call support. He uses two 18650 batteries to keep the unit mobile.
The housing made from 3mm MDF board is a bit bulky but necessary to house all the hardware. All edges are laser cut for port access.
Plans are already underway to add features like an upgrade to the Pi, a capacitive touchscreen, and a monitoring system to check battery levels.Robinson is open to anyone interested in improving the design and making changes they implement Seeking to share.He also made himself available on LinkedIn (opens in new tab) For those who have questions along the way.
