So I’ve been wanting to do this for a while now and finally got around to doing it. Using a box lantern style flash light and a spinning LED globe toy, I’ve made an inexpensive custom Giga Meter for approximately $15-$20. I separated the toy into 2 pieces; the battery compartment and the motor. I then cut a circular hole in the emptied flash light body for mounting the globed motor. I extended the wiring form the 2 halves of the toy and connected it to the existing flash light power switch. I did improperly wire thus damaging the whole set up the first time but the next day was able to get a 2nd globe toy and redo the same setup. I did have to split and re-glue the globe to mount it properly. The probes on the front are 2 thread spools glued to 2.5" bolts. After carefully drilling 2 holes in the flash light lens, they are directly bolted to the front. The LED display is a calculator screen glued on. I used a metallic red sharpie to write on the reading. Yes that is the reading Egon :sigh: was getting from the surface when they found the river of slime, 2.5. :angryvigo: I’ve posted Pics in the Props section.
