Claimed OU circuit of Rosemary Ainslie

[0c]

For any electronics dummies trying to make sense of all this like me, here's some 555 timer references that may help understand what all the "duty cycle" arguments are about. I especially like the animation in the first one.

Looks like the waveform may depend on where you take your measurements.

It also occurs to me that some people in public venues(i.e., libraries) sometimes experience problems, while others nearby have no problems at all.  If there was a widespread virus, that shouldn't happen.  Everyone's computer should be affected.  It's also randomly intermittent.

@Lee
Thanks for your answer, I tried 3 different web browsers Mozilla Firefox, Google Crome and Explorer, all reported the energeticforum.com could not be found...   

@wings

Thanks for the links, tried the first one and the energeticforum.com has loaded immediately.... now I can see it!  Without your link I cannot see it.

So what is the conclusion for my case?  My IP address (both at home and at the office) have been blocked? Can someone explain?
(I asked a friend to load it on his own computer yesterday, he lives near to the city where I am but he could not see it either, found the same error message, this may mean IP addresses for my country are blocked or there is somewhere a technical problem inside or near to my country which got out of function and blocks us?)

Thanks, Gyula

PS To the rest of the Folks here: sorry for the off topic!

jibbguy, you made so strong point about the strong point that I am affraid that now we have to wait untill the FULL JURY makes the deliberation, and not just the self-appointed Supreme Judges. Is there some critical time factor here that we are missing, that it is so important to rush to judgment? If so please let us know

You mean, like Northern vs. Southern Hemisphere?

Actually it looks like whoever designed Rosemary's 555 didn't know about these (standard) circuits, because I don't see any diodes in these, and there also are more capacitors in her 555 circuit.

I took the measurements in my basement kitchen, with a 1 megohm impedance oscilloscope. Actually, now three different oscilloscopes: the Philips, which does NOT EVEN HAVE a trace invert or polarityreversal function; the Tektronix which does, and the Fluke 199 which also does, and also has a cycle select function that also could be reversed.
That's right, the Fluke-O-Scope has 2 modes that could have been selected in error...which means only one out of 4 possibilities will give the "correct" duty cycle, that is, one that goes in the right direction on the display and is also calculated correctly by the scope software.

Tonight I will be looking at the behaviour of the circuit with a Hitachi VC-7504.

If I can figure out how to turn it on.

Hi Gyula,

It is entirely possible that your country ISP is banned, many forums block out trouble areas because of continued abuse from IP addresses .... some are shown here in a previous post of mine.
