The following Nokia Linux mobile phone is just a cover of the Nokia mobile phone. Inside is the author's newly designed PCB motherboard. Its size is exactly the same as Nokia's original PCB, so it is called " Notkia ".

The picture above is a "Notkia" Linux phone using the Nokia  168x series mobile phone case. brief introduction:
  • With Nokia 168x body: easy one-handed control, easy to put in your pocket

  • Running the mainline Linux kernel

  • Processor: Ingenic X1000E , 2200+ CoreMark, 64MB RAM

  • Storage: 32MB NOR + 4GB  SLC  NAND

  • Wireless connection: Lora, WiFi 2.4G, Bluetooth, GPS+GLONASS

  • Screen: 2.0'' 240x320  IPS  LCD, 3/4 visible

  • Sound: Yamaha MA-3 (YMU762) music synth  + regular I2S PCM codec

  • Camera: 5MP AF (1680 case only)

  • Power: Use battery solutions from TI, as well as standard  BL-5C batteries

  • Others: Type-C OTG, RGB LED indicator, temperature and humidity sensor , zero conflict keyboard

Actual operating effect

According to the author's introduction, this project has been submitted to the crowdfunding platform. After the fundraising is completed, the necessary software will be developed, and all PCB design files (including schematics and circuit board design files) will be open sourced. The necessary software includes:
  • desktop environment

  • T9 input method supporting English, Chinese, Linux commands and PL keywords

  • IME framework

  • terminal tool

  • various drivers

  • Class S60 multimedia player

  • Classic games: Snake, Tetris

  • ...

Nokia has a design patent for the case that Notkia is currently using, but that patent expires on June 23, 2023. The authors say that after the patent expires, they will re-produce a new plastic case based on the design, assuming of course that the fundraising goal is met.

For this "geeky" project, the author stated that he created it because modern smartphones are becoming less and less friendly to privacy and "hackers". He couldn't accept the manufacturer's changes to the phone and Android, and although he later discovered the Librem 5 Linux phone, he was discouraged by the price. At the same time, the author was getting fed up with the giant smartphones of the modern age—one that couldn't be controlled with one hand. Just this year, he accidentally discovered the Nokia 168x series mobile phone, and after looking at its PCB photos, he found that it has a huge space, the author believes that this can make a big difference, so there is now "Notkia".

Recently, some friends asked me to help me find some interview question materials, so I rummaged through the 5T materials in my collection, and sorted them out. It can be said that it is a must for programmer interviews! All the information is organized into the network disk, welcome to download!
