Spaceblimp 3 went up with two still cameras and a non-functioning video
|
|
camera. There are tons of neat pics from both. These links get you into
|
|
the series right before liftoff.
|
|
|
|
- [Camera one:
|
|
liftoff](http://gallery.jbwa.net/SpaceBlimp/SB3/Camera1/?g2_page=11)
|
|
- [Camera two:
|
|
liftoff](http://gallery.jbwa.net/SpaceBlimp/SB3/Camera2/?g2_page=6)
|
|
|
|
These are about as far out as we got before the balloon popped:
|
|
|
|
- [Camera one:
|
|
space!](http://gallery.jbwa.net/SpaceBlimp/SB3/Camera1/?g2_page=30)
|
|
- [Camera two:
|
|
space!](http://gallery.jbwa.net/SpaceBlimp/SB3/Camera2/?g2_page=38)
|
|
|
|
And then, recovery:
|
|
|
|
- [Camera two: land
|
|
again](http://gallery.jbwa.net/SpaceBlimp/SB3/Camera2/?g2_page=63)

## The Dataz! (Telemetry)
|
|
|
|
- Accelerometer data. Unfortunately, it looks like there was a bug in
|
|
the code and the second half of the data overwrote the first. Anyway,
|
|
here it is. It's 100 samples per second, start time unknown, but it
|
|
looks like it captures the pop, some freefall, and the landing.

If you spot something you can handle or wish to learn about, we'd love
|
|
to have your help. (Seriously, meeting more people like <u>you</u> is
|
|
major goal of HacDC.)
|
|
|
|

|
|
- Document [HacDC Spaceblimp 1](HacDC_Spaceblimp_1 "wikilink") on wiki
|
|
- Build primary & secondary beacon antenna
|
|
- Altimeter selection & purchase
|
|
- Purchase 32 GB SDHC memory card for video
|
|
- Build battery pack for video
|
|
- Make weatherproof labels/tags for capsule recovery (laminate, 3d
|
|
print, laser cut, etc.)
|
|
- Work on CHDK scripts for still cameras
|
|
- Build capsule/rigging/chute
|
|
- Vacuum test Geiger counter
|
|
- New software for additional sensors (add small μC?)
