What's inside Rotary Electromechanical vs Pulse/Tone Phones? -- The Electronics Inside 52

Traditional landline phones are on the way out. By 2025, in the UK, they'll be dropped in favor of IP telephony. It seems like as good a time as any to tear down some telephones!

That was a great project from DJ! What would you make it do as a desktop phone, just a voip handset?

If you want to keep it functional and iconic then converting it to work with VOIP or mobile technology is possibly about all you can really do with it. Perhaps you could get away with swapping the central printed label to convert it to circular E Ink or something along those lines.

If you want to let the creative juices flow though, then I think you could perhaps take a look at the general form e.g. the curves and reuse them to create a different 3D printed housing. Perhaps stretch it width-wise to accommodate a 7" LCD touch screen alongside the original dialler.

For me, I think the tactile feel of the old dialer is something that has been lost with the modern UI, and there was also something about the form of that handset with its annoying coiled cable. So nothing stopping you from reusing those basic parts within a complete new design.
