TGSL Tx oscillator set up.

[homefire]

Built copy of the Tx oscillator in order to mess with some coils prior to my build.

The thing refuses to Sing. How is it suppose to be getting the Feed back to Ring ? I don't see it. Via the Ground or Plus Power line?






Embarrassment Sets In.

Well I got it to sing. Issue was crummy Working but sick used Transistor. LOL

i was playing about with one to had the same problem some times it was hard to get it started. i was going to use a arduino to do he switching for more control

I had the 2N2907 as described but it wouldn't even sputter. Replaced it with a 2N3906 and lit lights right up. After that I think That's what I'll use in the build. I have a bucket load of the things.

Cool Idea on the Arduino . I have like 6 Nano's laying around Idle. Emmm. I purchased Two PCB. My intention was to Build One as Described and Double the Freq on the second for Nugget Hunter.

I have some Atmega328's from BangGood I purchased to do that kind of stuff with too. That would make a nice Test oscillator any coils, eaa? All it would take would be the Atmega, Two Caps and Crystal. Run in PCM ? https://www.banggood.com/DIP28-ATmeg...l?rmmds=search

Ahhh Another Some Day Project. Use the TGSL as the basis and you could DO THINGS with the Arduino. Freq. Custom Audio Target ID ? different Detector, OLED would look Sharp on a detector. LOL Your getting me side tracked.
