Dismantling the old Czech telephone is a beautiful useful art
The 20th century saw everything from phones to computers become mainstream. Many of these devices were beautifully designed mid-century, which is hard to tell about a lot of today's cheaper technology. [John Graham-Cumming] showed us an exquisite example, with his teardown of a simple Czech telephone.
The engineer is suspected of being a follower of symmetry . And then, who isn't?The model in question is a DS3600 phone built by Tesla Stropkov in the early 1980s. Despite this, it's a design that seems more of a 1960s origin due to its smooth curves and rounded features. It is a rotary phone, although a push-button version has also been produced.
Inside the phone is a simple one-sided circuit board clearly identified by neat silkscreen printing. The buzzer and a few capacitors make up most of the circuitry inside the base, along with the rotary dial. The handset itself hosts most of the other components, including the mysterious "WNB 068 hybrid circuit" which [John] could not identify with certainty.
It's great to peek inside vintage gear and see how things used to be. It's especially fun to think how simple telephones used to be compared to today.
