Well
I know many people use the phone to read and comment here ,and it can be a nuisance to size images [took me three attempts and still not right on my PC... :o

please have a good day , we are all rowing the same boat....and truly need to Vet all claims ,
so we can get where we're going faster..[not in circles]

that is no reflection on Dieter's share here , just a profoundly obvious,,,observation


respectfully
Chet K
PS
for much greater detail of below ...see first post in this thread.

You had better be careful there Chet.

BTW. the two wires that go over the 555, they look as if they're touching. They're not! and may not. The left one is much higher.


Also, a simple 5 cent blinking LED is used: when it blinks, the signal is dc. when it is lit continously then there is a pulse with low space voltage (mark/space, or low/high).


Or, use a scope. If you have one. Which I haven't.


I think such a short duty high frequency pulse is especially interesting for collapsing fields or impedance pulling, such as in jack no skills capacitive open coil system, which I actually built it for.

Hi AlienGrey ,

I just answer *****  ;) the  "ignore this .." is Sarcasm from TK , but i just answer  five stars to the initiative of  TK to put the circuit with scope shots, is really more productive then their habitual sarcasm words . Hope i clarify you or anyone about my answer .

Cheers

Note: The above results were obtained with a bipolar 555 flavor: NE555P. Using a CMOS 555 flavor TLC555CP the results are very different.

With the CMOS 555 the LED comes on brighter... because the duty cycle is much greater, due to the frequency being much higher while the pulse itself is nearly the same.

Also, I tried a Philips brand bipolar NE555N from Thailand -- interestingly it performs more like the CMOS, with a frequency of about 1.63 MHz and a duty cycle of 27 percent.

TK being on my ignore list, makes it silly to look at my own thread that is filled with his postings.


Please don't post in my threads anymore, TK, ok? Can you do that? Or do you insist on your "right" to aggressively disturb the peace of other people? If so, consider yourself a Forum Troll, spammer and stalker.

Your appropriate response to me should be "Thank you very much TK, I didn't know that the performance of this circuit depended so much on which particular kind of 555 timer is used, _because I have no oscilloscope_ and I can't test things properly."

Stick to your ignore list if you don't want to see my comments. If you don't want me to examine your claims, don't make them. If you don't want people to test "your" circuits.... don't post them. If you don't want to be criticized for posting huge images... learn how to use your computer or cellphone to make them smaller.
