Here the circuit diagram of Lantern dimmer/flasher designed by Tony Van Roon: Electronic parts List: R1 = 100K R2 = 100K R3 = 100K R4 = 100K R5 = 3K9 R6 = 3K9 R7 = 470 R8 = 100 R9 = 220, 1/2 watt P1 = 5K C1, C3 = 10uF/16V C2 = 0. 01uF, ceramic T1. This simple 220V light dimmer circuit can be used to adjust the brightness of mains lights. It also ca

n be used to adjust the speed of AC motors. It uses a triac, diac and has a radio-frequency interference (RFI) noise suppression circuit built into it as well. Schematic diagram: Component part: R1 = 10K R2. Here the 220V AC lamp touch dimmer circuit. By only touching this touch dimmer you are able to increase the light intensity of incandescent lamps in three stages. The touch dimmer is designed all around 8-pin CMOS IC TT8486A/TT6061A especially produced for touch dimmer applications. In the beginning, when mains switch is "on", the lamp. This is a 220V LED flasher circuit which is intended as a reliable replacement to thermally-activated switches used for Christmas tree lamp-flashing. This a cheap circuit and easy to build. Schematic diagram: Component Parts: R1_ 100K R2, R5_ 1K R3, R6_ 470R R4_ 12K C1_ 1000 µF 25V D1-D4_ 1N4007 D5_ SCR P0102D Q1_ BC327 Q2_ BC337 SK1_. This is the 200W lamp flasher circuit diagram. The frequency/speed of the lamp flashing can be adjust with the range of 1Hz to 5Hz. You can use the PR1 variable resistor (trimpot) to adjust the flashing speed. The duty cycle of lamp flashing can be adjusted using PR2 variable resistor. The DC input power supply.
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
