Re: [PSAS] IMPORTANT: We've got ten days to spend our budgeted funds!

Andrew, What are your thoughts on this: http://www.hobby-lobby.com/video-camera.htm They have video all over youtube. It's not HD, but it doesn't need a downlink either. Maybe good for backup video? If it's worth it, I'll send purchase info to Maria. ~D

Re: [PSAS] Missing wall wart

I remember seeing it, and someone has it. I'll check to see if the someone was me... Quoting Frank Mathew <[EMAIL PROTECTED]>: To Dan, Dave and anyone else. At the meeting two weeks ago, I may have left behind the AC adaptor for the pocket DVR. It's 5VDC, very small with

Re: [PSAS] Big Rocket

Wow... Yeah, I don't think I'd try that... Interesting thought on the separation system, though (pg 4). We had a similar idea, but I think the one we're using may be more reliable. The article says he's got a ten foot diameter parachute... Can that be right? It seems W

Re: [PSAS] Last-min launch issue: Mandatory Driver Training For PSAS/PSU Students

you won't be attending. (You may attend a future launch, and would still have to attend the workshop.) I apologize for the short notice (I just received event confirmation today), but please, please try to make it. It's very important! Thanks! See you tomorrow! -- Maria **

[PSAS] Specific Rocket Pic

Does anyone have any photos of the rocket hanging from the torsion spring wire at Tim's house? The rocket would have been upside down, hanging from the antenna bar. Please send it off the list if you have one. Thanks! ___ psas-team mailing lis

[PSAS] Flight data

All, I'm doing some unit testing on the roll control. Does someone (maybe Keith??) have some rocket flight data that gives accelerometer readings (long axis only) with a known peak altitude? Sample rate is really not too important, since I can just interpolate between points. One f

Re: [PSAS] When is the next launch?

Quoting Jeremy Booth : Oy. When's the launch? I thought I'd heard the 29th and 30th, but I don't see that on the OROC site. I see a "Spring Thunder May 21st ? 23rd" event. is that it? That's it. We need to start a page on the wiki for logistics, equipment,

[PSAS] Lost 1/8th inch torsion rod

All, I'm trying to locate a 1/8th inch diameter, 36 inch long rod used to measure the mass moment of inertia of the rocket (or any other object that is attached). I need this rod to measure the rocket Ixx inertia, and I have torn my house apart trying to locate it. It was last seen o

Re: [PSAS] Lost 1/8th inch torsion rod

I don't think that statistics would help us, except that it's less likely that all of them are broken. The dial type torque wrenches are usually based on the properties of a steel bar, so they usually read correctly unless they are completely broken. Having more than one might

Re: [PSAS] Lost 1/8th inch torsion rod

I looked outside the plastic tubs. I don't think it's there. The tubs are only ~2ft on the diagonal. Too small i think. Well, thanks for looking, anyway. I thought someone (maybe Dave?) had bigger tubs. The rod would have been 36" when new, so shorter with some sort o

Re: [PSAS] Trimmed in-flight video

I clipped the video down to just the interesting bits: http://people.freedesktop.org/~keithp/psas-lv2c-2010-06-27.avi Take note of the flys (maybe some kind of bee?) on the rocket, particularly in the frames right after ignition and lift-off. I think we got him

Re: [PSAS] Sony-sponsored student rocket project

Learning from the failures of others, what can we gain from this? * On clusters, design the ignition to minimize the chance that two motors can ignite, yanking the ignitors out of the third motor (perhaps make the rocket light it's own ignitors?). I wonder if they would share their ig

[PSAS] Spin-can bearing is go for flight

Now witness the power of this fully armed and operational spin-can bearing... It fits, it spins... Quite a bit more notchy than I was hoping, but that's expected from the way it was ground. We'll do better next time with a more rigid grinder spindle. Check out the construct

Re: [PSAS] How long are the launch tower sections?

Um, over ten feet?? Unless you have a ladder rack, I'd say put them in the toy hauler... Quoting Jeremy Booth : Can I get the length of the launch tower sections? I will have more than enough free cargo area for them, even if they are over-length, but I would like to prepare. Al

If the intent is to increase traffic, can we add some keywords like 'high power amateur rocketry' to the videos? I think we'd get a lot more hits. Quoting Nathan Bergey : Fixed. On Wed, Feb 16, 2011 at 6:02 PM, Jeremy Booth wrote: I've been finding that directing

I must have tuned out during the discussion. Last I heard we were still thinking June. I have stuff going on the 16-17 and 23-24 weekends. Is there any way we can use the wiki/calendar to put up people's conflicts? Dan Last week we talked about trying to launch mid July in Brothers
