▲Latest censor attempt by Nokia Corporation.
▲Support by Hackaday staff.
Note: This is NOT a custom ROM for Nokia phones. It is a freshly designed PCB with exactly the same dimensions as the original PCB of the Nokia phone, so it can be put in the Nokia's shell.

Why do we need it?
- People who don't like HUGE smartphones do exist on this planet
- Modern smartphones are becoming increasingly privacy unfriendly & hacker unfriendly, and the worst thing is: privacy is already a business for these businessmen:
- There are many "privacy oriented" products on the market that aren't even designed by people with privacy awareness
- And it's the same for hackability

The Notkia uses the Nokia 1680/1681/1682 form factor. Yes, it has a proper shell. The 1680 has a camera, and the other models don't. It can be comfortably operated one handed, no matter in public transport or in bed. Having it accidentally falling into your face won't cause extreme pain. It can be put in almost all pockets and bags without a problem, and won't scratch your clothes or pull your beach pants down.
▲ It can be comfortably operated with only one hand
▲ The weight is only around 66 grams
The main reason of we choosing the 168x series is because it has the largest inner space among all the feature phones we inspected so far. Its inner space is big enough to put a spring antenna inside! Also, its power connector has its own piece of plastic on the PCB, this means it can be changed to another type of connector without problems. However it doesn't look very pretty, and I hope we can get enough money to replace the plastic clip surrounding the charging port.
▲ I tried my best to make the Type-C surroundings look good
This design is only patented in US and AU, and will expire on 2023-06-23. After it's expired, we can produce brand new plastic cases based on this design, assuming the fundraising collected enough money.
Why the X1000E?
- Very low power consumption: 0.3W running the CoreMark benchmark and 0.003W in standby
- Acceptable performance: 2200+ CoreMark, a bit faster than the RPi Zero
- Built-in RAM: saves PCB space, while enough to launch 16,384 Apollo 7s
- Correct toolchain for it can be installed in minutes, not hours or days
- Supported by mainline Linux kernel
- Datasheets are publicly available: no more hide & seek with vendor
