Skilled maker Justine Haupt has created a fantastically unique mobile phone complete with the paper display and rotary dial. The mobile phone is open source and all the design files including Arduino code, mechanical STLs and KiCad have kindly been made available, if you fancy building your very own.
“Why a rotary cellphone? Because in a finicky, annoying, touchscreen world of hyperconnected people using phones they have no control over or understanding of, I wanted something that would be entirely mine, personal, and absolutely tactile,while also giving me an excuse for not texting. The point isn’t to be anachronistic. It’s to show that it’s possible to have a perfectly usable phone that goes as far from having a touchscreen as I can imagine, and which in some ways may actually be more functional. More functional how?”
Features of the unique cellular mobile rotary phone with ePaper display :
– Real, removable antenna with an SMA connector. Receptions is excellent, and if I really want to I could always attach a directional antenna.
– When I want a phone I don’t have to navigate through menus to get to the phone “application”. That’s bullshit.
– If I want to call my husband, I can do so by pressing a single dedicated physical key which is dedicated to him. No menus. The point isn’t to use the rotary dial every single time I want to make a call, which would get tiresome for daily use. The people I call most often are stored, and if I have to dial a new number, or do something like set the volume, then I can use the fun and satisfying-to-use rotary dial.
– Nearly instantaneous, high resolution of signal strength and battery level. No signal metering lag, and my LED bargraph gives 10 increments of resolution instead of just 4.
– The ePaper display is bistatic, meaning it doesn’t take any energy to display a fixed message.
– When I want to change something about the phones behavior, I just do it.
– The power switch is an actual slide switch. No holding down a stupid button to make it turn off and not being sure it really is turning off or what.
– So it’s not just a show-and-tell piece… My intent is to use it as my primary phone. It fits in a pocket.; It’s reasonably compact; calling the people I most often call is faster than with my old phone, and the battery lasts almost 24 hours.
