My machine translator from Bulgarian to English generates different sentence:

"Alex makes a new circuit diagram of metal detector." Note that there is a letter "s".

However you started to make this like MikeBG - without soldering iron, with Ohm's law only.

It's easy to only write without picked up soldering iron .And I do not live in the forest,i know law of OHM.

Сашо, не ме разсмивай защото аз ще изпусна крокодила, който държа по-горе!

Here's a THREE BOX metal detector which can operate as TWO BOX:

My translator says that "компютърът ми е стар" is "My computer is old".
I don't know Bulgarian, but is "стар" really translated as "old"? It looks more like another [similar] English word. Perhaps that's where it came from.

So guess you aspire to become a super star?

[mikebg]

All Bulgarians now are super stars :-(
Bulgaria now is the poorest country in the European Union. Currently, when Sascho and I are near to our old computers and joke, people came out to protest in the streets because poverty is unbearable. We can not pay our bank liabilities, drug, heating and electricity. Our children leave the country to seek a better life abroad, and we parents are left here with old computers to be able to talk to them via SKYPE.

oh Bulgaria... why you are so rich and beauty but not for us

Bulgaria today...

[mikebg]

oh Bulgaria... why you are so rich and beauty but not for us

Anatoly,be optimistic! We will soon make it possible for all.

Bulgarian people are very poor in money, but they are very rich in ideas. Now we make something more intelligent than the Arab revolution and the occupation of Wall Street. The serious changes have already begun.

We believe that soon will return home our brains working abroad. Currently they send in Bulgaria not only money to survive their parents and relatives, but also ideas what to change and how to change. Soon Alex and I will give our old computers in museum.

hi.replace t1 and t2: 2n2219a best result

good luck

How about this, dear Mikebg?

How about this, dear Mikebg?

The increased voltage of transistors and other changes that are known

[mikebg]

The increased voltage of transistors and other changes that are known

Starmoml, what circuit diagram you use for your 2box project?
Don't increase supply voltage. This can't help to increase sensitivity.

Please write answers the following questions in your native language:
1. How you test that your TX circuit operates correctly?
2. What is resistance of your coils?
3. How you adjust coils in perfect induction balance?
4. Explain how you adjust the gain of RX preamp?
Then post me the answers via email.
You can post answers in this thread using a machine translator, for example this:
