Introduction: How to Make Conductive Paint at Home

About: I am an electronics hobbyist and I love to share my works with others

in this tutorial, I am going to show you how to make conductive paint at home and also showing how to control light with this

Step 1: What Is Conductive Paint

Conductive paint is an ink that results in a printed object which conducts electricity. It is typically created by infusing graphite or other conductive materials into ink.

Conductive inks can be a more economical way to lay down a modern conductive traces when compared to traditional industrial standards such as etching copper from copper-plated substrates to form the same conductive traces on relevant substrates, as printing is a purely additive process producing little to no waste streams which then have to be recovered or treated.

Step 2: How to Make at Home

we can make conductive paint from old zinc-carbon batteries

Step 3: Now Let's Build a Touch Circuit Using 555 Ic

components needed for making the circuit

  • BC547B
  • 1k resistor
  • 1N4007
  • CD4017
  • NE555
  • 100uf capacitor

Step 4: Circuit Diagram

Step 5: Working

This Touch Switch circuit is based on 555 ic and it will detect static voltages produced by the human body.

we connected a touch plate to the trigger pin of 555 Whenever we touch the conductive plates of the touch sensor, the 555 Timer is triggered. The output pin goes high and goes low after some time that time can be controlled by changing the RC network of this circuit. and we feed that output to a toggle switch
