Evaluation Board For The Ad9834 Direct Digital Synthesizer
This document outlines the design of a low-cost 90 W flyback switching power supply intended for use in a multi-sync color monitor. To reduce screen interference caused by switching noise, the power supply can be automatically synchronized to the fixed...
7Segment Common LED UV Exposure Box
7-Segment Common LED UV Exposure Box Circuit Diagram. Features: Utilizes Stan Ocker's circuit design, employing a PIC16F84 microcontroller to count and display the time.
The 7-Segment Common LED UV Exposure Box Circuit is designed for applications requiring precise timing and display...
switch mode power supply design of current load sense circuit
A suitable method to sense when some LEDs in a garage door opener are illuminated. A power source, potentially the same as Vout, connects to a 1.5 kΩ resistor, which then connects to six LEDs followed by a transistor. This...
Novel White LED Torch
This design is directly derived from the manufacturer's datasheets, but its application is relatively novel. Initially intended for high-visibility LED bargraph readouts, the LM3914 is utilized here as the foundation for a 10-step variable brightness current-regulated white LED torch. The...
LED Dice circuit
The IC1 is a 555 timer IC connected for astable operation. The clock pulses are fed to the IC2 via the 10K resistor. The IC2 is a 10-stage counter; output 6 (pin 5) is connected to RESET (pin 15), thus...
LEDs and resistors circuit
An LED, or Light Emitting Diode, is a semiconductor device that allows current to flow in one direction while blocking it in the opposite direction. This characteristic makes LEDs polarized components, having a positive side known as the anode and...
New Knight Rider LED Board
The TL082 (Or a TL072 also is OK) Creates an Adjustable Sawtooth Generator. (It also has a Square wave Output, but it isn`t used here.)
The Left and Right LEDs are connected in series, and if this circuit is used on...
ALPHANUMERIC LED DISPLAY PROJECT
A tiny sandwich flag connected perpendicular to the motor spindle aids observation of how long it takes to complete one full rotation. This worked initially, as each burst from the capacitor barely moved the flag 1/4 of a rotation. As...
LED monitor for 12V Battery
A Very Simple circuit and some Variations. Play with it.
All parts are cheap and should be easily obtained. None are very critical.
The circuit in question is a basic electronic assembly designed for educational purposes and experimentation. It typically consists of...
