[Marc] has an old Voigtländer Vito CLR film camera. The camera originally came with an analog light meter built-in. The meter consisted of a type of solar panel hooked up to a coil and a needle. As ...

However, it was Cameron's guerrilla filmmaking tricks – including using a light meter to dictate where he could film the ...

Built-in light meters have made cameras so sophisticated that it is almost possible to simply aim, focus and shoot without worrying much about shutter speeds or lens openings. Almost, but not quite.

PITTSBURGH (KDKA) -- The old Duquesne Light meters are about to become a thing of the past. "We're replacing all the electric meters within our service territory with the new advanced electric meter," ...

Shooting with a classic Leica M film camera is a tactile, deliberate experience—one rooted in simplicity and mechanical precision. But for those of us using meterless models like the M2, M3, or M4, ...

This circuit can easily be assembled on a small piece of prototyping board. Use low-current types for the LEDs. They have a low forward voltage and are fairly bright at current levels as low as 1 mA.

[Peter Demchenko] wanted to use a low power TS555 in an ESR meter design. The problem is, he needed to handle significant current sink requirements for cases where the capacitor under test had a low ...

The James Webb Space Telescope (JWST) has already captured some incredible images of our universe, with some game-changing insights to boot. But researchers at New York's Rensselaer Polytechnic ...

Hi guys, I just received an email from David Moran and he sent me his capacitor meter project with pictures and a little presentation. Here are the details and schematic. Here is the schematic of my ...
