Axiometa BrodBoost-C is a USB Type-C breadboard power supply with a simple design that powers both rails of a breadboard with voltage adjustable between 3.3V or 5V. It also includes an on/off switch, ...

The tester circuit itself includes a transistor that, when paired with the transistor under test (TUT), forms a multivibrator circuit. The tester features five closely positioned sockets, each clearly ...

According to California’s 2016 Building Energy Efficiency Standards, the percentage flicker of light-emitting diode (LED) lighting fixtures should be below 30%. However, the percentage flicker of ...

If you’re working with 3.3V or 5V circuits, it’s easy for you to throw on a power or status LED here or there. [Tom Gralewicz] has found himself in a pickle, though, often working on pr… ...

A novel EM-field measurement method by using a λ/2 dipole LED antenna was proposed. The λ/2 dipole LED antenna can be lit by the received DC power fed by rectifying RF signals. The LED's brightness ...

In this project, we will design and build a 12V battery level indicator with the help of a quad comparator OPAMP based IC LM324 which lets us use 4 OPAMP based comparators on a single chip. We will ...
