Discover how to build a simple wireless power transfer system at home using readily available components like enameled copper wire, an LED, a 2N2222A transistor, and a 9V battery. This step-by-step ...

Description: Using a bunch of WS2812B led chipset I build a net of lighting for my jumper, this is the first version so do not expect too much from it, version 2 is on it's way. I designed the small ...

A low pulse on this pin (below 1/3 of VCC) sets the internal flip-flop and makes the output go HIGH. When the voltage on this pin reaches 2/3 of VCC, it resets the flip-flop, and the output goes LOW.

Abstract: This brief introduces a current calibration circuit that is specifically designed for use in a column-parallel Dual-Ramp Single-Slope (DRSS) ADC. This circuit creates two current sources ...

This project is a collaborative VR environment where an instructor on a PC can supervise while multiple students connect from mobile VR viewers. Breadboards, components, wires, and logic are ...

Abstract: This paper presents an electrolytic-capacitor-less LED driver. The driver is made up by the integration of two converters in parallel. The first converter is a Buck-boost used to deliver ...
