Hand tools and fabrication machines
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
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.
we can make conductive paint from old zinc-carbon batteries
components needed for making the circuit
- 1k resistor
- 100uf capacitor
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
