The main operating parameter is relatively simple: Keep the current through the LEDs constant and under the specified maximum. Traditional power supplies have accurate voltage outputs with variations ...

Instead, the pattern is a “mosaic of functional circuit board elements,” Dbrand CEO Adam Ijaz tells The Verge, that showcases components like resistors, capacitors, and traces laid out in a ...

This is a very simple LED dimmer circuit which has 2 transistors, 1 resistor and 2 potentiometers. Typical segment displays LEDs consume around 25 mA for each segment and should be limited to this ...

paired with 0804 resistors and 0402 LEDs. [Zach] made this board in his apartment, using a machine of his own creation—the Circuit Graver. You might be expecting some kind of laser-etching ...

Through-hole assembly means bending leads on components and putting the leads through holes in the circuit board, then soldering ... it’s possible to create resistors, capacitors, fuses, and ...

Prototron Circuits Southwest Inc. started out humble, at least in Tucson. Parent company Prototron Circuits of Redmond, Wash., was doing work for big-name companies in the Seattle area including ...

The output voltage increases until the current through the LEDs reaches the value ... or if one load is shorted. The circuit contains one bipolar transistor and resistor per string, a voltage ...
