Electronics enthusiasts or tattoo artists may be interested in a new touchless switch which has been created and implemented into a tattooing machine allowing the tattoo artist to use gestures to signal the machine to turn on or off.
Watch the demonstration video below to see how the an Arduino development board has been used together with a distance sensor to trigger the tattoo machine into action.
YouTube user Wildman Tech explains more about the project.
My friend Andrew Hanson is a tattoo artist and he has tasked me with building a motion sensing tattoo switch to replace the filthy foot switch he uses with his tattoo machine. All of his other equipment is sterile, except the foot switch and that’s a problem. This is the solution! It can actually be used to turn anything on or off.
This project uses an Arduino Uno, a distance sensor module, and an FET driver transistor module. They both take their power from the Arduino main board. The distance sensor output is fed into pin 2 on the Arduino and the FET driver input is taken from pin 9. The Arduino Uno board detects the tattoo artist’s gestures via a distance sensor, and signals the machine with an on or off output.
