Physicists Design $100 Handheld Cosmic Ray Muon Detector

11/22/2017 6:39 PM

"Physicists have designed a pocket-sized cosmic ray muon detector to track these ghostly particles. The detector can be made with common electrical parts, and when turned on, it lights up and counts each time a muon passes through. The relatively simple device costs just $100 to build, making it the most affordable muon detector available today."

If you want to build one for yourself:

This looks like a prefect subject for Useless Gadgets.

The later "useless gadget" thread was closed due to useless responses.

And exactly why would I want to detect muons? but

Perhaps we don't have a use for it except as a desktop conversation piece, but some people do:

This is my desktop conversation piece. I've had it since they first came out. I have a personal connection to it. It still works.

OK, so I'm a dinosaur.

Useless? It's a reminder.

Muon. Take a drink.

Pulled these images from the site. Looks expensive to build & it looks like you need some expensive equipment to build it.

I do believe that such "rays" were thought to be the reason for occasional problems with early RAM memory chips in computers....the Military Standards of the day required a metal piece on each chip to reduce the effects....I particularly remember that the early 256 and 1k chips were thought to be sensitive in this area.

Anyone else remember these "thoughts"?

By the way, I do not need such a detector myself!!!
