Use a standard paperclip to create a wiper that can be inserted into the hole of a wiper detector. Include a 1N34 diode for added functionality. This device can be used with or without an extension, offering flexibility in its application. Additionally, it can be wired in two different ways: one configuration includes a variable capacitor, while the other does not. Note: Scale will require adjustment due to export measurements being in millimeters.
