Hi All,
Just for curiosity please look at this 6800 uF electrolitic capacitor
purchased in Cina !
http://sinocom.ru/attachment.php?attachmentid=2124&d=1302278111
The left capacitor is encapsulated in original conditions while the right
capacitor has
been decapsulated.

I use ARISSatTLM to decode and forward data from ARISSat-1. Usually the
'mode' shows HIGH POWER or LOW POWER but today I saw at least one frame
showing EMERGENCY although a later frame was back to LOW POWER Can anyone
tell me the conditions that trigger this EMERGENCY mode and what changes to
operation take place in this mode.

Hi Dick!
Thanks for collecting and forwarding data from ARISSat-1.
Emergency mode is entered when the power management software thinks the
battery is dangerously low. It reduces the frequency of telemetry to
one 30 second period every 5 and a half minutes or so, and turns off
unnecessary loads otherwise. Evidence suggests our battery has failed
"open", so the software must have taken a sample when the solar panels
were at a poor angle with respect to the sun.
See http://arissat1.org/v3/images/PDF/janfeb11_monterio.pdf for full
details.

Has anyone had any success running ARISSatTLM on Linux under Wine?
It seems to install ok (I'm using Crossover Office), but when I launch it I
see the briefest glimpse of a telemetry screen, and then it goes away (exits
or crashes). No log files that I can find for what it didn't like.
If it matters, I'm running OpenSuSE 11.1 / KDE 3.5 on a 3.2 GHz Pentium-4 HT.
Thanks,

Given that we have no battery, is there any use for the low and emergency
power modes? Can they be disabled? If the solar panels can provide the
minimum power to keep things alive, even in worst case angles (can they?),
then having the spacecraft act so skittishly is kind of annoying.

Domenico,
It can help our community, if you could provide some info on the vendor.
was it an eBay vendor?

Hi Tony, N2UN
It would be very interesting !
I normally do the decapsulating operation in my old
electrolitic capacitors replacing it with modern smaller one
having the same capacity and it works but never I found
on the electronic market electrolitic capacitors of this
type !

That pic has been floating around the Internet for several years - it's not
just a single vendor (and shonks aren't endemic to China).
Check out http://www.google.com/search?q=fake+capacitors&tbm=isch for many

Unfortunately, counterfeit parts are flooding the market, especially parts
in limited supply. Some components may be painted and stamped with the
choice of a difficult to obtain component.

This is old, old stuff. The backstory to is is that it's an *American*
device, not Chinese, and it was done that way to disguise fitting a more
modern capacitor into a vintage amplifier.
I can't remember why they went with 2200?F instead of 6800?F - possibly the
guy that did it felt that 2200?F was adequate. It was over a decade ago
when I first saw it along with the writeup ;-)

Surely that's the minimum power to keep things alive *when it's in emergency
mode*.
Oh, and top-posting is really annoying.

Is Prospero still transmitting?
Sometime ago, I?think in 2007 the BBC TV program Coast was on the Isle of
White
where there had been a test stand for rocket testing.
They talked about Prospero and had a short piece?with some people trying to
hear
it with a small yagi. Apologies but the memory is a bit hazy.
Subsequently I spent quite a few hours listening for it with a tower mounted
5el
X yagi, an up to date set of keps,?and an FT847 - after several days, nothing
heard.

Although funding to command the satellite ceased in 1996 the Prospero
real-time oribtal tracking page says it was heard in 2006.

I would image now the Mullard Space Science Laboratory in Surrey are
attempting to command the satellite again the 137.560 MHz beacon would
become operational if enough of the satellite is still working.
Given the 40th anniversary of this historic UK spacecraft takes place in
October I would expect the media would be very interested if any amateur
succeeded in receiving it in the coming weeks.
Audio recordings of the 0.3 watt phase modulated signal with PCM at 2048

Stuffing capacitors is a standard technique in the restoration of old radios.
If anyone had the time to waste they'd probably find the original of that
picture on one of the many US websites dealing with restoration work.
The picture was circulated around 2007/8 in an email attempting to smear
components manufactured in China.
