coil generator : tester of coils

[dbanner]

Thanks KT, I'm interested in everything you have.
Problem is time.(Money)

enjoy
BTW i have bara boards in red. do not know why the people are so cold.

[dbanner]

Don't know what you mean
The pictures I posted were only to illustrate RED pcb.
People like to buy candy, just because it looks great.
Yes I can open such files.(DjVu)

[kt315]

DB you can write in russian now

[kt315]

Baby candy.

DB i use selfmade synus generator, but had bought it. i also bought counter https://www.ebay.com/itm/DIY-Kits-1H...53.m2749.l2649

Can you put here chart of Russian components symbols for schematics. I am collecting old Soviet era circuits that I can find. You can give also.
Not just metal detectors, anything else will also be good

have it but in DJVU format. are you able to open those files?

[dbanner]

Thanks for the Alphabet soup. I can save and use as reference whenever you put circuit here.
I will do some more reading on the topic of capacitors to increase my knowledge.

Russian alphabet I don't know, but it looks like electrolytic caps are rated 6? So I'm guessing 6 volts rating. So power supply is restricted to below this. I say 3-4.5 volts.
What I find interesting is C2 and C3, connected back to back, as substitute for non polarized cap.

DB big problem you do NOT know what is REAL substitute for nonpolar capacitors. it is NOT so simple you are grasp to yourself.

DB i did probe all colors... but just green is only good transparent. you know i am tester and learning all things around.

[dbanner]

This is very good. My one and only criticism is the color of board. I think for small stand alone pcb(not meant to be placed inside any box), red is more attractive like baby candy!
Very good work as usual.
That cap looks odd, I know it's a good cap, but it looks ****ed up.

Resistor are rated in watts, which is a function of voltage(volts) and current(amperes).
So power supply max must also take into consideration the maximum current that will flow through any given resistor multiplied by the voltage drop across the resistor. The resistor must be rated at suffice wattage to accommodate this.
