Today we got the 555 timer fixed and also fixed up another one so we have a backup timer. The timer is based of one found here which was designed by Scott Fintel. We plan to launch thursday (tomorrow) or on friday, depending on weather and avaiable time.
As I stated in the last post the rocket is a 2 stage rocket. The booster section is made from 5 spliced two liter bottles and is about 36" long. It has three fins which are made from cardboard laminated in packing tape. The sustainer is a 25" piece of FTC tube with two bottle tops spliced on both ends. The sustainer also has a electronics bay for the timer and a camera as well a the chute bay. The entire sustainer measures in at just about 4'. For fins the sustainer uses 4 pet fins. Here is a picture of the booster and sustainer next to each other.
The electronics bay is fairly basic it contains the timer, a 9v battery and a small gumstick camera. Here is a view of it out of the tube.
Thats all for now.
P.S. I will do a post on how the staging mechanism works for thoses interested soon.
