Dear All.

Welcome to a new thread dedicated to Nelson Rocha and his Mini Radiant Exciter circuit. Builders most welcome.

I used the Acronym N.R.M.R.E. as it's quite a mouthful and I'm rubbish at typing !!  :)

For deeper research might I suggest a visit to Nelson's You Tube channel.

Here's a couple of Nelson's videos.

It's already very clear that the circuits in the videos differ quite strongly from the posted schematic below.... This is where you guys n gals come in!!    ;)

Investigation!!

I built a version some time ago. Video here. https://www.youtube.com/watch?v=m6lmd0HKxOw

I found this when my channel suggestions came up. https://www.youtube.com/watch?v=iER4K1O7iMc

Nelson's work has inspired a few!  Thank you Nelson Rocha.

Good luck everyone, Graham.

Thanks Grum, I'll look into it later on.

Do we have part numbers or at least V-A ratings for the bridge rectifiers?

Also, is the wire going through the center of the toroid, or is that overlap just drawn for convenience?


And this schematic of the internals of the TIP122 Darlington transistor belongs here.

Somewhere in my many JT videos I ask, and answer, the question "what happens after the light goes out". That is, when the supply voltage is no longer high enough for the JT to light up the LED(s).  The particular JT I used continued to produce an oscillation just like what you show at the end of your video-- a low voltage sinus oscillation that went on for a long time apparently without losing amplitude until it finally stopped. Without the LED being on to drain the power I guess it was in a "high Q" oscillating mode. Which of course doesn't actually explain anything, just gives it a name (which may not be correct.)

I think it was this JT but I can't find the right video showing the "dark oscs" at the moment.

I've a batch of TIP122 transistors on order, should be here in a couple of days.

Dear TinselKoala.

Many thanks for dropping by.

With the schematic, sadly what you see is what you get.

Your point about the wire running through the toroid is something that I had missed, perhaps we should allow for it's inclusion/removal during construction?

Cheers Graham.
