A 12V Car Charger For ASUS Eee Notebook
The ASUS Eee is an exceptional ultra-portable notebook that includes nearly all the necessary features for technology enthusiasts while omitting unnecessary elements. Additionally, it boasts an impressive build quality.
The ASUS Eee series is designed with portability and functionality in mind,...
LED Boost Circuit
The completed board may be driven by voltages between 0.8 and 3 Volts. While the basic design goal was candle-like light from a single cell, the values used were chosen to allow safe operation from 3 Volts so you can,...
LED Stroboscope with EG1951-ND
The rotary switch is available for $5.00USD as of 2003 from DigiKey under part number EG1951-ND or EG1952-ND. It is a real pain to operate this circuit without a proper switch. You can put multiple 4017 ring counters in series...
12 Volt Toilet Tank Refiller
A flushing toilet is often taken for granted by city dwellers, but it can be a luxury for those living off the grid without access to utility water and electricity. This circuit enables on-off pump switching for a small 12...
led flashing circuit
Its state is constantly changing, and this change affects the flow of current and voltage, which is visible with the two LEDs. The speed of the LED flasher can be adjusted with potentiometer P1. As an astable multivibrator, the circuit...
Flashing LED unit
The circuit presented is designed as an LED flasher that creates a rotating effect when the LEDs are arranged appropriately. It operates with very low current consumption and can function using 3V button cells. The first integrated circuit (IC1), a...
Comes with rechargeable lead-acid battery LED emergency light circuit diagram
The circuit diagram depicted in Figure 5 illustrates a system for charging a lead-acid battery using 220V AC power. The circuit employs a capacitor, buck converter, and diode rectifier for this purpose. A red LED indicates the charging status. When...
Dark-activated LED or Lamp Flasher
This circuit adopts the rather unusual Bowes/White emitter coupled multivibrator circuit. The oscillation frequency is about 1Hz and is set by C1 value. The LED starts flashing when the photo resistor is scarcely illuminated. The onset of flashing can be...
Automatic White-LED Garden Light
This white LED driver circuit is suitable for garden lighting applications. It automatically activates the LED at night and operates from a single 1.2V NiCad cell, which is recharged by a solar cell during the day. The prototype utilized the...
