OK, I've got this old 1000 VA UPS that is unreliable as far as powering a
server goes, but it still hold a charge. On the back are several standard US
configured female outlets.
Can I use this as a power supply for launching my rockets? The output is

Hey all,
I'm going to Kennedy Space Center and will be taking one of the
tours...which one is better...
The "Then & Now" or "Nasa Up Close" tour? I know the general gist of

Let's start a list of stuff that can explode, "given just the right conditions",
to help out the retards (apologies to retards, for comparing them to ^H^H^H):
Grain dust...   Gasoline...   Heating Oil...   Kerosene...   Vodka....
Paint thinner...   Deisel fuel...    Acetone...   ...

I understand one can make good nozzles from quartz sand and phenolic
resin. It is also possible to phenolize paper. I would think the latter
would make good and strong rocket casings. (Especially good would be
woven carbon in a phenolic matrix (lightweight and doesn't melt at high

I keep seeing posts that say APCP can not detonate.  Well you're all wrong.
It can.  You just have to get it in large enough quantities to sustain a
shock wave.  Rule of thum is motors over 60" dia and several tons are large
enouph to do just that.  Heck, just for grins here is a ...

I am coming too Toronto in Febuary 2007 and while I am there I would
like too look out the local rocket club( if there is one,which i'm sure
there is)and would they be flying .
If anyone knows could please let me know

I'm about to start work on a 2.25" 29mm two stager and have been
wondering how I'm going to handle the ignition of the sustainer.  I
could use a commercial rocket timer/stager but the $$$$ is a factor.
I started thinking to myself, exactly how hard would it be to build a

Just curious, has anyone seen any of the old electronics payloads made by
MITS in the 60's-70's era?

In the ATF's court filing on 13 October, they claim that the burn rate
of APCP has lower and upper bounds of 36 mm/sec and 143 mm/sec. Which
would yield a maximum burn time for a G40 (they mention a CATO of one in
the report) of about 1/3 of a second. Needless to say, this ...

This message will report on the BATFE’s Notice of Proposed Rule Making
(NPRM) on the definition of propellant actuated devices (PADS)and our
October 17 hearing in US District Court.

Since the October DARS launch was rained out, we have moved the Extreme
BP contest to the November 18-19 Turkey Shoot launch in Windom.
Stuff as many black powder motors as you can into a cluster or stager
(or clustered stager :o) and come on out for lots of fun and some

Does anybody have a current email address for Mike Dorffler, the seller
of scale data CD sets?  The mkdorffler@earthlink.net address at
http://www.yellowjacketsystems.com/jimball/scale-data/Saturn-CD.pdf
bounces.  Is he still selling data sets?

No really, I realized I just posted a lot of stuff in that 'range
question' posting and it REALLY is true and from the heart.
The question I have is, why do you people put up with government?
Is it because most of you could NEVER govern your own personal lives?

  How to calculate the maximum rocket flying range?
  Is it able to buy a can of pure oxygen from the internet?
  If i want my DIY rocket to fly as far as possible, what fuel i
should use?
