This is a mobile phone that:
– First and foremost, will be a well-working reliable phone
– Is as open-source as possible *while also being cheap*
– Can be assembled and repaired independently
– Is easy to get parts for
– Doesn’t have apps with privacy concerns
– Allows to write your own apps in Python
It costs about 50$ in parts, and all the parts are available on eBay/TaoBao/etc, most of the phone can be assembled with just a soldering iron. User interface is written using Python
and is being morphed into a lightweight phone-tailored UI framework.
A crowdfunded manufacturing run is expected in a month – kits will be available, as well as a small batch of fully-assembled phones. Subscribe to newsletter below!

- Modern phones are getting more and more complicated and hardware-packed. Unfortunately, that means they’re becoming less modifiable and repairable.
- Phones are getting more and more integrated. Unfortunately, that means more and more possibilities for manufacturers to lock them down without allowing us to modify them.
- More and more software&hardware is kept closed-sourced. That means it’s harder to learn, experiment and customize your phone.
The factors I’ve listed (integration, complexity and closed-source) are necessary in the world we’re living in, with all the advances in engineering, competition between companies, as well as laws in different countries.
However, what if we could have a phone free from those constraints?
So, ZeroPhone project was born. Nowadays, we should be able to assemble a phone from easily available parts, using cheap boards that run Linux, and we should be able to adjust it to our needs – unlike as it is with modern phones, when we have to adjust ourselves to suit the workflow that the phone offers. With ZeroPhone, hackers can finally have smartphones that are going to work for them and not against them, people with special needs will be able to have to have custom-tailored phones, and people that want to protect their privacy will have a phone that respects that.
Technical challenges are: developing PCBs that’d be reasonably feature-packed, but with easily sourceable components that could be soldered without special tools, as well as developing mobile phone software that’d be open, high-quality and highly modifiable to suit any needs people might have. However, much bigger challenges are – building a community of people experimenting with ZeroPhone platform, keeping ZeroPhone open-source and independent of any harmful influences, and experimenting with new ways of integrating smartphones in our lives without having to lose privacy in return.
