Oh, look, yet another use of a Raspberry Pi that I did not need….


Ever wanted to build you own cellphone? Well now you can with this guide that uses a Raspberry Pi, PiTFT, and a FONA to make a functional cellphone that you can call your friends with!

Things You’ll Need:

  • Raspberry Pi computer, the Model B or Model B+.
  • Resistive 2.8″ PiTFT or Capacitive 2.8″ PiTFT – 2.8″ TFT touchscreen for
  • Raspberry Pi. The capacitive version looks nicer and has a glass top that does not require pressing down, but it’s more expensive!
  • SD memory card, 4GB or larger.
  • 1200mAh Lithium Polymer battery
  • DC-DC converter
  • FONA + Antenna
  • “Hands-free” Headphones with Microphone
  • You can use a DC-DC converter to give us 5V for the Raspberry Pi. Or just go with a big USB battery pack such as this one, but it won’t look as tidy.
  • I really should stop with the sarcasm on these weird uses of these small computers.
    I’m sure, someone, somewhere will be building this for who know why….. I mean you can go to a any Op Shop (Thrift store in USA) and get a perfectly good flip phone for 5 bucks or a smart(ish) phone for about 10 bucks.
    Much better battery life, much more durable and just better all round, but hey, you did not build them, you just saved them from landfill.

    Am I getting old and grumpy? [Don’t answer that – anyone!].
