Givi Motorcycle Trunk LED Mod circuit

12V Lead Acid Battery Discharge Indicator

The circuit was designed to provide an indication before a 12 V lead-acid battery reaches a discharged state using an LM723 voltage regulator and a positive NPN standard voltage. The circuit utilizes the LM723 voltage regulator, which is well-suited for battery...

LED light

The goal was to create a compact flashlight that could be held in the mouth, easily stored in a pocket, and positioned on a surface to project light upwards. The budget was set at approximately $15, which was significantly lower...

LED Light Pen

Physicians and repair engineers frequently utilize small light pens for visual examination purposes. Although these pens are rugged and can be expensive, their vulnerability lies in the bulb, which is a replaceable component. In practice, this often translates to the...

256 Run LIght (for the 8bit bin to 256 / 1 of 256)

Switch S1 allows for direction change (Up/Down), Pot1 adjusts the clock speed, and LED D1 serves as an indicator for the clock speed. The circuit utilizes a switch (S1) to control the direction of operation, allowing for two modes: upward and...

LED Flash Driver with HT2050

This circuit is based around HT2050 manufactured by HOLTEK semiconductors. It is a low cost, low-power C-MOS LSI designed for lamp and LED flash driver. It requires minimum external components. You can operate it with just two AAA cells or...

Hydraulic oil Automotive LED Alarm SL322C schematic

The circuit illustrated in the figure is a hydraulic oil level alarm system for automotive applications. It consists of a light-emitting diode (LED) driver, the SL322C integrated circuit (IC), a voltage regulator circuit (CW7809), and hydraulic oil level sensors (W1,...

Simple Motorcycle Wiring Diagram for Choppers and Cafe Racers

Many inquiries arise regarding motorcycle wiring, particularly among individuals attempting to repair their blinkers or seeking to streamline electronics for custom builds. A crucial aspect of constructing any chopper, bobber, cafe racer, brat bike, or rat rod involves eliminating unnecessary...

LED Modulation Circuits

Common Light Emitting Diodes (LEDs) require a direct current (DC) forward bias of 10 to 20 mA for optimal performance. The maximum allowable DC current typically ranges from 30 to 50 mA. The emitted light color, or wavelength, from an...
