Since I continue to wonder what the mugs of fellow industrious electronics gurus look like, I've reincarnated the thread. I shall start with my evil left eye. Followed by my less evil and larger right eye.

Here is a pic of my and my 7' rocket
Interesting story about that monster... When I first got it it was 6.5' tall, after the second launch I lengthened 18" to make room for a second parachute (it has two, a small one which deployed at apogee and a large one that goes off when the rocket get to be 800' above round level) to make it a full 8'. But then I was trying a new hybid engine design (.wmv) which didn't go so well. but when I rebuilt it I shortened it a little (in hopes of keeping it above the mile mark with the hybrid) to 7'. Now every inch is used, the first 36" is the engine (either 1.5" or 2" in diameter depending on if I use the 500n/s or 1000n/s engine) the next 12" is the small parachute, the next 6" is the recovery electronics, the next 18" is the big parachute, and the last foot is the nose cone (which will hopefully have a GPS in it in the near future). So, yes I do have a 7' rocket that is longest right before it explodes... And yes I do use every inch of it

That actually is pretty cheap for a hoodie, they're expensive. I have seen some for 40 or 50 dollars. Granted, they were nice, but not that nice. The funny thing about it is the fact that you are paying more for that hoodie because it has some logo on it, so in effect you are paying to advertise their product.
