12V LED Flasher for Cars

This is so wonderful circuit diagram Because you can up grade the out look of you car or van by using this simple circuit .Actually this is a blinking Led circuit on the other hand this circuit is called multivibrator circuit.The impotent thing of this circuit is this circuit can be operated with 12V power supply





Note

# By using R2, R3, C1 ,C2 you can change the speed of the circuit

# Fix this on a pcb

# Don't supply more than 12V

# This circuit can generate about 5W power

Simple ufo Detector Circuit Diagram

This is some what different concept But here I have used very simple method.Most of people in the world find UFOs by looking at the sky most of time we can see some rich people buy cameras and focus them to the sky.But those unites are so expensive here I have shown you very simple diagram.When UFOs pass our area normally those machines out put high magnetic field so here we have used that magnetic power to detect them.when a UFO passes your area the magnet of your circuit will move. then the circuit will be switched on





Note

# Use 3V power supply

# Click this to make UM66 music circuit

Simple Water Level Detector

This is so useful circuit diagram because this circuit helps us to detect water.When the water come and touch the sensors it will make a sound.Here I have used common transistor bc109. Actually you can modify this circuit.. By using a relay you can switch on or off your water motor I will tell you them in my next post.





Note

# Use 6V to power this circuit

# The distance between the circuit and the sensors should be short.

# Build this circuit on a pcb to get good result.

230V Blinking LED

Already I have posted 230V LED circuit diagrams.This circuit is different than those circuits.Because this circuit is blinking circuit.And here I have used common parts so you all can find them easily.Already I have attached this circuit with our doorbell switch then the visitors who visit my place at night can see it well.





Note:-

# When you deal with 230V be careful because it is dangerous
# Fix this circuit in a plastic box
