This is my fist instructable and part of a bigger build. I wanted to document these steps for reference and for anyone to gather ideas.
I purchased this meter with the intent of building a mad scientist or Frankensteins lab prop. As the picture shows the glass is broken and there is no needle for the measured voltage. ( the one needle with the round bit on it is just an indicator).
Step 1: Inspect and plan
I did find the coil still functions and only missing the needle. I epoxied on a new needle made from a piece of thin copper wire painted black, adjusted the counterweight and was able to make the meter move to full deflection with less then 1 volt. I added a resistor and an old volume control potentiometer and now can move the needle anywhere from 0 to 300 volts with just a 5 volt input.
Next Lights, The scale has some convenient mounting holes at the bottom, a perfect place to mount a board for the lights.
