- Remember the number of pictues that timer will take per
flight is (Number of
Groups) x (Number
of Pictures) Don't forget to check this or you may
get too many or too few pictures per flight.
- Too only take pictures at apogee use a program like wRasp
to calculate the time to apogee and enter it as a Launch Delay. After
liftoff the timer will pause up to 25.5 seconds before
taking the first picture.
- The haze of summer can produce fuzzy, boring pictures
when you launch your rocket very high. To get pictures at
apogee and then again close to the ground calculate or
observe the descent rate for your rocket. Program the
timer to take two groups of pictures with no Launch Delay. Insert a Group Interval to
allow the rocket to descend closer to the ground before
taking the reaminder of the pictures.
- If you accidentally activate the timer while in Armed Mode quickly turn
off the power or switch the timer back to Standby Mode. The timer
will immediately stop taking pictures. If you powered the
timer off it will power up in Post-Flight Mode.
Disarm it to reset it.
- To program the timer to take as many pictures as fast as
possible first, make sure you have trimmed the controller.
Second, set the Number
of Groups to 1 and the Number of Pictures
depending on the number of exposures on the film you are
using. Make sure there is no Launch Delay.
- Most film has extra exposures on each roll. A roll of 24
often has 26, a roll of 36 sometime 39. Take this into
account. If you expected your camera to rewind the film
after a particular flight read up on the manual rewind
button on your camera or just burn off the extra
exposures to use up the roll.
- Some cameras cycle more slowly when they have film in
them. If you test the camera's cycling speed without film
and then fly it you may get dropped pictures. The Olympus
Stylus can cycle in 0.8 seconds without film but needs
1.2 seconds with film. Take this into account when
setting the Picture
Interval and Trimming
- Setting the Keepalive
flight parameter to a value of 1 will trip the shutter
every 10 seconds while the controller is armed. This can
be useful while bench testing the controller and trimming
the shutter parameters. The advantage is that you need
only arm the controller to start the cycle without
needing to simulate launch.
