My friend Anmarie asked if I could make a fake Geiger counter for her band's CD release show tonight (littlehexes.com/). Here's what I came up with.
The "wand" has a pressure sensor under the thumb. The guts of the thing is an ATmega chip on a dorkboard which reads the sensor input and pulses the meter, speaker, and light if the random number generator picks a number less than the wand's input value. Dead simple, but it works great.

1961 Algonquin Geiger Counter
Invented by Mr. Walter Woytowich, Deep River, ON
This Geiger Counter was given by Mr. Woytowich to Miss. Noulty to show the inside of the counters.
Again, this is a taken-apart Geiger Counter and a generator from a hand-cranked telephone from World War II. This "Sound Powered Telephone" generator maker is unknown.
The comparison of the two generators that are missing their cranks shows the type of materials Mr. Woytowich used in making his initial Geiger Counter. As most of his materials came from war surplus stores and yard sales, it is unsurprising that his counter's generator closely resembled a hand-cranked telephone generator

Even though I've never bought anything in this shop I love the way it looks - all reflective and shiny...
Residents of Geiger, a small community in Sumter County, Alabama, work in their community garden. A multiyear partnership with Alabama Extension at Auburn University has helped Geiger residents make important changes not only in their diets but also in their community.
Here's one from the archives: NIWX 8924, and EMD SD45 still equipped with its 20 cylinder 645 prime mover, leads a pair of empty centerbeam cars and WRIX 3000 near Medical Lake, WA. The 8924 was built for the Seaboard Coast Line as number 2024. It served on Montana Rail Link for several years before being sold to NIWX Corporation and subsequently leased to the Eastern Washington Gateway Railroad. It was eventually sold to VLIX and restored to its original paint and number. It recently gained some fame while accompanying Clinchfield Railroad F3 No. 800 during CSX's 2017 Santa train under the guise of CRR No. 3632.
