If you want to have a unique, old-fashioned mobile phone then look at this mobile phone with the rotating selection disc, reminiscent of the 1970s-2000s.
Brookhaven National Lab engineer Justin Haupt, has built one rotary dial mobile phone that is not only functional but also available to assemble it yourself through a "do it yourself" kit. The kit is not cheap, it sells for $ 240, but if nothing else it is a unique mobile phone.
Of course don't expect the conveniences of a smartphone, as it's just a phone and nothing else. At its heart is a custom ATmega2560v mainboard, Adafruit Fona 3G cellular gear and a rotary dial from a phone Western Electric Trimline, all housed in a 3D printed casing.
It also contains a small 2,1-inch screen that can display missed calls and other vital messages, while the buttons shortcut allow you to quickly select your favorite contacts. You can also check your remaining battery life (it lasts for about 24 hours) and signal strength. Of course the phone is not waterproof.
The kit includes only the motherboard and the 3D printed case, so if you want to make it you will have to do some other shopping.
