Obsolete electronics can easily be repurposed into something new, and that’s exactly what Tindie seller Oscilloscope clocks does with outdated electronic tubes. Using a 3″ DG7-6 cathode ray tube (CRT), an autonomous clock with electrostatic deflection is born.
This particular clock is homemade and has dimensions of 5.5 x 6 x 8 inches. The acrylic shroud is not attached, it simply sits on the base of the clock. The board includes pots for adjusting the height, focus, astigmatism, brightness, and centering of the display.
The display alternates between digital and analog every ten seconds. It also moves slightly every six seconds to avoid burn-in on the CRT. Every aspect of the clock can be replaced or repaired as needed, including the microcontroller.
This unique oscilloscope clock is a perfect example of how makers can marry obsolete tech with modern methods to produce something entirely new.
If this looks familiar it’s because we featured the blue version back on October. But they’re just so cool I couldn’t help giving another shout out!
