In the end, A Usable Rotary Telephone From A Convention Badge

A couple of weeks in the past we featured a challenge from [Dan], a work-in-progress through which he was once attaching an EMF 2019 digital convention badge to a rotary telephone. On the time we seemed ahead to his development, anticipating perhaps to peer it in our travels spherical the sector at EMF 2021. We need to say we did him a disservice then, as a result of he’s made superb development and has now turned it into a fully functional cellular rotary phone.

When we left him he’d interfaced the dial to the badge and now not so much else, but it surely was once sufficient to spark our pastime as a result of we predict there must be extra re-use of outdated digital convention badges. Since then he’s reverse engineered the original bell with the assistance of a motor driving force and an affordable DC-to-DC converter, and the handset with the guts of a Bluetooth headset as a result of in experimenting he controlled to kill the badge’s audio circuitry.

The outcome will also be observed within the video under the destroy, and we need to admit it appears lovely just right. Relying the place you’re on the earth you’ll both love or hate the ringing sound, however this is of little result to the application of the software. In case you have a drawer stuffed with convention badges collecting mud, in all probability it’s time to present them a 2nd glance.
