Default New video camera with potential...

Check out this video camera from Hobby-Lobby. It records on SD cards, and seems to have a really good frame rate. (Addendum: How does 25 Frames Per Second sound?)The demo video they show is clear and sharp when used on an RC airplane. With a 2GB card, it can store up to 30 minutes of video.

The price is not too bad, either. $98.80 plus shipping.

Resolution is 640x480 for video, and 1280 x 1024 for still shots. Camera measures 3" x 1.5" x 0.5". Contains a rechargeable Li-Ion, which uses power from your USB port to recharge in about 1 1/2 hours.

Oh, good. You're posting pics. I guess that means you're downloading the launch pics next?

The professional camera that I use to film weddings with is 24 fps, as are Hollywood movies... it's a good frame rate.

How much does it weigh?

Default New Plan -- Non Aspera

A "cousin" to the Andromeda. Retains the open-fin pattern and general shape, but marginally simplified. The forward payload tube can be either clear plastic or standard spiral-wound. The nose cone needs a paper transition wrapped around the bottom portion so that the forward fins have something to glue against; If you use thinned white glue, you can bond them to the clear plastic tube without smearing or fogging. This gives you the ability to remove the nose cone for payload access.

All of the following specifications are based on a sport launch condition, with no payload mass.

Length: 28.70"
Diameter: 1.04" (ST-10); Rings are 1.84" (ST-175)
Fin Span: 5.04"
Weight: 1.84 oz

B4-4......355'......Dv 9 FPS......36" x 1/8" rod
B6-4......360'......Dv 4 FPS......36" x 1/8" rod
C6-5......810'......Dv 6 FPS......36" x 1/8" rod

The phrase "Ad Astra Ad Aspera" means "To the stars, with difficulties". Non Aspera should thus be translated "No Problem!"

Enjoy!

Talking Jay's new design -- ZETA

In the "Scrounged-Up Designs 2006" thread, James Pierson wrote at 07:56 PM on 08-02-2006:

"I personally think that Jay is holding out on us and keeping his best designs for himself. (Feel the love, Jay.)"


I hate to admit this, but Jim was right.

However, I recently noticed that EMRR had a "Box O' Parts" contest (which I was too busy to participate in, due to the recurring intrusions of real life), and I threw together a list of parts that *I* would have included. Then I took it one step further, and tried to figure out how *I'd* put them together.

To that end, I present the "Zeta" (pronounced "ZAY-tuh").


Parts list (all components by Semroc):

BC-760 Nose cone
SE-14 Screw eye
ST-7120 Body tube
ST-530 Body tube (2)
ST-1040 Body tube
CR-710 Centering rings (2)
EH-28 Engine hook
TR-7 Thrust ring
LL-117 Launch lug
EC-130 Elastic cord
SCK-24 Kevlar shock cord
CP-12 Parachute (Use a streamer for B and C-powered flights.)
3/32" balsa


(This may take a few consecutive posts, so I apologize in advance.)

As always, pertinent comments or questions are welcome. Impertinent ones will be dealt with accordingly.


Thanks, and cheers,
