A VU meter, also known as a Volume Unit meter, is a device used to display the audio signal level in decibels (dB) in real time.

The emf detector described in this video has a minimal number of components, which means that it is simple to make, and does not require any tuning.

Electronic version of the Compass, where the position of the needle is indicated by group of a three light-emitting diodes

I need over 8 digital channels and 2 analog channels for my controller, which would be an expensive, but I can make my own custom controller for much less.
