The original design for what would become the modern tattoo machine was invented by Thomas Edison in 1877. The heart of the machine is its power supply. The type of power supply will determine what type of tattoo machine you are trying to build. Some power supplies deliver up to 20 volts of power. The higher needle count you are using, the more power you will need to supply the tattoo gun. Instead of giving the tattoo gun more speed, setting the voltage higher will draw the needle down with more force.
