Anyone using a 35+ or has a manual that can explain to me the strip feature? I can't figure out how to load in the background to be stripped. Thanks, Geo...
The term "tube" is used for a Bicron or Harshaw tube/crystal combination. These have the 12 or 14 pin bases and need to have a socket and dynode attached. ...
George, as I remember (that should be your first warning), it uses one of the memories. Record the background in one memory split and use the strip to remove...
This was a 'just for grins' project that happened to work. The 125 had no tube and low voltage when I got it on a trade. I pulled a diode in the HV circuit...
Thermo sent me some info the other day, including product specs on their handheld Radeye G and Radeye PRD units. At approx $800 and almost twice that for the...

Hi all, I got the ZnS screen (the ZnS powder is placed on a thin flexible plastic sheet) and the mylar from GEO. Now I am thinking about how to replace the old...

Hello all. Its been 2 years in the making and now I am sure its working and basically calibrated. I am still using the eberline ESP-1 as an operating platform...
Hi, could anyone tell me what type is pictured as the photo for the club? How much do they go for? Maybe someone has one for sale? Its really neat! Thanks! ...
The picture is a one-of-a-kind DIGI-LENi, one of the many prototype experimental units based on the LENi. Regular LENis' are sometimes available on eBay. Geo...
There's an old seafarer's tale that goes like this: I sailed to the Canary Islands and found no canaries there. Then I sailed to the Virgin Islands and found...
Good idea, but my Spectrum Analysis handbook suggests using plain 'ol warm water to milk the Bi-212 onto nickel: "SUGGESTED EXPERIMENTAL PROCEDURE 1. Acquire a...
I made a special LENi to use with the Russian pancake probe as is now being offered for sale from Europe. A simple mod reduces the HV to the desired level of...
But you have to add a resistor in series with the base as the lad had written. I've tried it on three ENI boxes for Q4- the HV oscillator. One with George's...

Upon acquiring an I-129 sample, which has a low energy Gamma signature ( around 30 keV), a specific probe setup was needed to analyze this isotope. Taking the...
Hi, I've at long last started a PIC microcontroller project that I've been thinking about for ages. It's a Digital Scaler. I'm working on a couple of versions,...
No info on the wall thickness, and measuring the efficiency is one of my future projects. The I-129 IS an NIST source so accurate measurements are possible....
