Here is the circuit diagram of lantern dimmer / flasher designed by Tony Van Roon: There are two circuit modes: dimming and flashing. The flasher mode is useful for warning other drivers of your troubles and it may be adjusted to have a very short flash duration for long-term use as when the car must… Read More »
This is the schematic diagram of LED indicator for 220V AC Mains which can be used to indicate that the cable lines is connected to 220v electrical installations. The current through the LED is not limited to the resistor, but the capacitance of the capacitor. The capacitance can be selected so that the current passing… Read More »
This is LED emergency light that will turned on automatically when mains supply fails, and turned off when mains power resumes. This circuit produces highly bright because the use of ultra bright white LEDs. This circuit also has its own battery charger. When the battery is fully charged, the charging process will stop automatically.
