Simple power Supply for LEDS
LEDs are great display tools. Their prices have decreased to a point where they are replacing more conventional light sources. In one sense, their characteristic need for low voltages is an advantage, e.g., compatibility with I.C. drives, but this voltage...
Fake Alarming LED Flasher
The parts to the right of T1 form a simple Joule-thief ('Blocking' oscillator) circuit which boosts the 1.2v supply to 3.5v to operate the LED. C1 is used to extend the charge and discharge cycles to increase brightness and efficiency....
High-Brightness LED Grow-Light
This project page has evolved into a design discussion. Constructive suggestions and collaboration are still welcome. Please refer to the comments section.
The project focuses on the development of an electronic circuit design, which has transitioned from a simple project overview...
Switching intensity of LEDs
A circuit has been constructed that functions unexpectedly. The circuit utilizes red 5mm LEDs as diodes, a 3904 NPN transistor, and resistors as indicated in the schematic. Logically, pressing the push button normally open (PBNO) should result in the destruction...
Case Modding
The aesthetics of case modding, which involves modifying a PC's enclosure, provide ample opportunities for discussion and original circuit designs. Low current LED indicators are typically installed in PC enclosures. While this approach conserves energy, the LEDs do not emit...
25 LED Sequencer schematic
This circuit is same as the above setup to drive 25 small Xmas lights. The lights operate at about 200mA and 3 volts. The supply voltage is set to 5 volts and the 4017 counter output will drop about a...
High-intensity LED Warning Flasher
This circuit is designed as a warning flasher to alert road users to dangerous situations in the dark. It can also serve as a bicycle light, subject to traffic regulations and legislation. White LEDs are recommended when the circuit is...
LED audio peak level
A peak level indicator when a signal exceeds a certain maximum value. It can be quite useful, for instance, with tape recorders, mixing consoles etc. One of the most important requirements of a peak level indicator is that it should...
Simple One-Wire Touch Detector
This simple circuit can be used to activate various devices, such as microcontrollers, relays, secret alarms, or even to turn on LED1, which illuminates as long as a metal plate is touched. The circuit consists of a voltage divider with...
