My coockie or what it arranges to stay logged in... does not work.. i keep being logged out and when i log in again i am not in this treath again..
any advice on this guys?
I had the same problem .... what worked for me is do not go to page 3496 of this thread. All the other pages (so far) seem to work except that one.
That was the current page right about the time of the data centre fire...

Great... first it was a wandering singularity that randomly consumes our pix, unmaking their entire existence... now eevBog has a haunted page on the TEA. What's next.... dragons and sword-weilding aardvarks...? Why not throw a Smurf or two in the mix for good measure...? smeeeeesh...

So it's only haunted for "special" people...? Even better.

I think I need to seek help soon.
Got a RTC1002 just two weeks ago,
now got a good deal on a RTB2004.
Aaargh.
You're not crazy. One bedroom apartment here and this is my living room.
You're both into green walls!Pink curtains too ?
Kiss my arse...and ass too.
Isn't that the dwagon's job?Well I guess you could say that you've just been FIRED!!
Hi Ceberus,
during the last year I also played with different OCXO solutions for GPSDOs. I learned that it's better not to cover the OCXOs with foam because the heating-cooling-regulation needs the convection with free air.
It only makes sense to avoid direct air flow from a vent. All the professional solutions I have seen use the "naked" OCXO.
I have done this only one time since I had a OCXO without Vref output and I used a cheap TL431 for this. I put it at the can of the OCXO and covered it with foam.

I don't know why you'd think that. If the control loop for regulating the temperature of the OCXO was so badly designed that it needed some external cooling to be stable your point would be well made, and the control loop would not be. As it is I've never seen this and wouldn't expect to. If it needed a specific amount of convective cooling the data sheet would have to specify the amount of heat dissipation necessary and again, that is not something that I've ever seen. So I think you're a bit off with the expectation that "the heating-cooling-regulation needs the convection with free air".
In general most ovened things, be they XOs or voltage references benefit from having as much isolation from the local thermal environment as possible. Some ovened references go so far as to place the oven inside a dewar flask ('vacuum' flask). That you don't see it in many commercial designs is probably more likely down to being cheap than being about doing the job properly. Look at the old HP crystal ovens - dirty great things with loads of insulation inside the outer metal cans.

Hotspot on your iPwn. No prob; eevBlog is pretty low BW. Given the current server pageload times, you probably won't even notice the difference...

Disagree. In fact its a consequence of control loop theory. A thermostat with NO loss and a finite heat capacity cannot be stabilized.
Its like a power supply with a huge capacitive and (almost) no resistive load. They go unstable as well, because the PSU can supply current, but (not SMUs) cannot drain any.
