Description

This is a printed circuit board for making a functional replica of the 10 LED meter used by Olivia in season 4 episode 3 of the Supernatural TV series. To assemble this circuit board you must be comfortable working with and soldering electronic parts.

This meter was only shown in one episode of the series but was a very standout meter. This is a prop only version with no EMF detection abilities. It is hand crafted on perfboard using point to point solder connections. This is truly a one-of-a-kind meter. The meter is designed with a test button similar to the other EMF meter for creating custom EMF events and also has 3 pre-programmed event sequences. These pre-programmed sequences can be added to or changed by reprogramming the ATtiny85 code. An ATTiny85 is used to control the DFPlayer sound board and the analog meter deflection.

A partial build video is available on my YouTube site. This meter is built on a perfboard so assembly is at the discreation of the hunter (Ah, builder). A schematic is available along with a Bill of Materials (BOM).
