This is a fully functional electronic multi-tool modeled after the Sonic Screwdriver used in the hit series Dr. Who. This screwdriver is built using an Arduino Pro Mini to control it. Among the various features and functions that this device has are an EMF (electromagnetic field) meter, voltage detector, dog whistle, brown note tone generator, sound level meter, ohm meter, volt meter, and an IR universal remote. It can also serve as a laser pointer or a flashlight and of course there is several settings for making the LED pulse dramatically. The device can also be configured to have an electromagnet or output voltage supply if necessary.
