Bucket List: a thoroughly modern ENi or....

Geo Dowell All Messages By This Member #722 Bucket List: a thoroughly modern ENi or....Industrial LENi? They say imitation is the sincerest form of flattery.. G-10 Glass Epoxy circuit board, tin plated brass through-holes. Silver plated solid copper wiring with Teflon sleeving Actually it's a rugged reusable test be for some radical upgrade experiments to the ENi/ LENi Geo DSCN5338.jpg
Michael C All Messages By This Member #724 not directly on topic..? I notice the wire you run alongside C1 and C6, the full width of the board.? What is that for??? and that new board is great.? Got to be a lot easier to solder on than these old phenolic boards, and more durable.?
Geo Dowell All Messages By This Member #726 That wire across the board coveys the ground connection from one side to another, replacing the trace cut when we shear-cut off for the LENi Pro mod.(the battery box having already? been cut down in the original LENi mods.

Michael C All Messages By This Member #728 Edited what is the LENi PRO?? I was confusing that with CDV 700 PRO.? ?Are there instructions for the LENi PRO, or,? is it a LENi with all the additional mods done to it?

Michael C All Messages By This Member #731 so a pancake tube in the bottom, speaker on the side and all the other LENi features....? cool? ?
Geo Dowell All Messages By This Member #732 Yes, that's about it. Right now, I'm proving the way to add variable HV with a knob inside, and that small circuit adds a lot more stability to the whole GC, but requires 2 9V batteries to work plus the two D cells. Next step might be to eliminate that by eliminating the transformer circuit which is the power hog, replacing it with a modern solid state module. This should increase battery life enormously, but for now nothing needs to be done, because we can already select any HV we want via the present Zener stack, and I have PC Boards with 3 position switches for that ready and in stock. I had you wait off on the cut trace part because I wanted to go all the way back to the beginning to make sure it was 100% the best way to go, and now I have done that with these last 15 ENi boards. So the way you've been doing it is verified once again. Thanks for getting me off my but and doing this, it's been on the Bucket List for years to do it, now it's done we can look for more options to add. Later we'll discuss the unit's input sensitivity, something that needs to be boosted if scintillation probes are to be used, but the solution is a preamplifier circuit, and we have had that all along. Most users will always use GM tube probes anyway, so we don't include that preamp normally unless requested. Dr. Prutchi did include his version of the preamp in his ENi PRO article, and the timer and digital counter too, we thank him for exploring that area. I always encourage others to build upon my modest beginnings or making these worthy old workhorses better and to offer more individual choices for users to have their particular version of fun. Peter, (I call him P.), of our groups came up with a really helpful audio circuit for using the LENi when prospecting, instead of clicking, it converts the clicks to an audio tone, more like a metal detector sounds . I like that a lot and want to build one for myself just for fun.

Michael C All Messages By This Member #733 开云体育 okay now I want to turn this ENI into one of those since we know the ENI is working.? And I would like to do it for the experience.? Could you drill or stamp the holes in my case?? I don't have the right tools.? and can I buy needed parts from you? toggle quoted message Show quoted text -------- Original message -------- From: Geo Dowell <GEOelectronics@...> Date: 5/28/22 5:28 PM (GMT-08:00) To: [email protected] Subject: Re: [CDV700CLUB] Bucket List: a thoroughly modern ENi or....
