First Class Expansion Capabilities


WiPhone is expandable through daughter boards. The whole back of the phone is a replaceable panel that accepts a standard 1.6mm thickness PCB, which you can use to add whatever functionality you like.

People Like The WiPhone


This is a great cross over between what people know (phones) and what people really want to do (hack).

Nathan Seidle
SPARKFUN FOUNDER

The WiPhone is a really rather neatly put together project.

If you want a phone that respects your right to repair, this is the project to look at.

So excited by this project I tried to make one myself.

Hack It Like It's Yours


WiPhone is built for hacking, not for some big corporation's bottom line. Complete disassembly in less than a minute, using only 6 screws. The operating system firmware is easily modified, and simple enough to be understood entirely by one motivated person.

Not only is WiPhone capable of completely free calling, it's also an open source, self-contained Arduino development platform. Unlike most other dev boards it comes in a nice package, with a battery, power supply, and on/off circuitry. Once your project is done, instead of an eyesore of tangled wires and stacked boards, it's compact and visually appealing.

A Phone You Can Own

(Not One That Owns You)


Modern smartphones are more and more a tool we don't own, but instead one we're only allowed to carry around. One that serves the interests of various tracking networks, corporate boards, and government organizations. You don't own it, it owns you. It tracks you, serves you ads, and sucks away your time with mindless dopamine hits. We want a phone that's back in our control, optimized for our convenience.
