Artistic Desktop Geiger Counter - Radiation Detector - Custom Made

Description

This is a real Geiger counter, artistically hand made by Chuck Pound in September 2019. Intended as a desktop display, it can be used for science experiments or simply be a conversation piece. This radiation detector uses a Geiger Müller tube (Soviet surplus SBM-20) to detect Beta particles, Gamma rays, and X-rays. The box is made from copper clad FR-4 printed circuit board (copper clad fiberglass). The top is made of glass so that you can see all of the electronics inside. The glass top is made of "water glass" which adds just a bit of wavy distortion when you look through it (artistic!). This all results in a nice looking copper and glass desktop conversion piece. Oh yeah, this is the third Geiger counter in this series, the first and second versions were sold in our shop. Three more were been special ordered, delivered for Christmas 2020.
Listed as "New - Open Box" since you would be the first person to own the Geiger counter other than the person who made and is selling it here on eBay.
Please be aware when viewing photos that there is distortion caused by the "water glass" top lid.
This Geiger counter can be used for testing Vaseline glass, radioactive fiestaware, radium watches (please be careful), dryer lint, and other similar items.
Calibration of this device is only relative, more lights only mean more radiation detected. They do not necessarily indicate the danger of said radioactivity, but they do look pretty! Instructions will be provided with your purchase. For more accurate readings, this Geiger counter can be attached to an Android device such as a cell phone, tablet, etc. or a Windows computer. You may be able to use the device with iOS/Mac devices, but that has not been tested as I do not own any iOS or Mac devices.
You can connect the Geiger counter to the microphone input of an Android device to get more accurate readings using "RadMeter" from Google play. A TRRS style cable would be required for this. The Geiger counter can also be connected to a Windows computer running special software. Using a computer you can keep records, upload data to your own web page, or to radmon.org to share your background radiation readings with other people, click the link to see these readings, my Geiger Counter using the same kind of GM tube is on the RadMon map in southwest Wisconsin. The software is available for free on radmon.org, though I would suggest some donation to be offered if the software does what you need. There are other Windows software available, but they have not been tested. A special cable makes it easier to connect to a Windows computer, purchase from gq_electronics_llc, or I can send one to you with the unit for an additional cost.

I will repair the unit for free (you pay to ship it to me) if it fails within 65 days of shipping date, as long as the unit has not been physically damaged, modified, or altered in any way. That is, if the electronics fail for no apparent reason, I'll fix it. If you drop it, open the box and damage the electronics, or something like that, I may be able to fix it for a fee. Free repair does not include the Geiger-Muller tube. If the Geiger-Muller tube fails a fee will apply and repair could take a month or longer to obtain a replacement if I do not have one on hand. In the 6-7 years I have been making radiation detectors I have never had a GM tube fail in service. I have one that uses the same GM tube that has been running 24 hours/day for two years with no issue. (These GM tubes are easy to find on eBay, search for 'SBM-20 Geiger' and match the photo to the tube in this unit. I prefer seller pave_taras. Easy to replace, the GM tube simply snaps in place.) You must contact us before returning the Geiger counter. Condition decision will be made by seller.
