- Get state feedback on the launch pad
Possible Solutions
Camera | Mass | ||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|
Cost | Battery Life (on standby) | State Feedback? | Maximum Recording Time with Big SD Card | ||||||||
GoPro Session Black | 120g | $151 | 2 hours WiFi; 8 hours Bluetooth | via Bluetooth | thermally limited, otherwise infinite | ||||||
GoPro Hero 7 | 116g | $400 | 2 hours WiFi; 8 hours Bluetooth | via Bluetooth | better at 2k60, probably not great at higher resolution | ||||||
FireFly Q6 | 42.5g | $62 | infinite (off) | hackable | uncharacterized |
Considerations
- Stick with Fireflys
- pros: safest bet within the timeline with minimal work
- cons: lowest upside, unreliable based off of previous flights, batches ordered can have slight differences, no feedback
- safest bet (but no feedback on the launchpad)
- changes can include:
- change connector and get BBC working
- Stick with Fireflys but research GoPros for future flights
- pros: will allow better development of the GoPros for future flights
- cons: most work and will ultimately stick with the unreliable Fireflys, no feedback
- balance between both ideas
- Go with GoPros (via Bluetooth) and fallback on Fireflys
- pros: highest upside by eliminating camera boards, improving reliability and getting instant feedback on the launch pad (on/off, focus correct)
- cons: limited/insufficient battery life, integration concerns, uncertain about starting cameras from bunker (could be unreliable connection), will drive the most change in an already short timeline (including a higher cost), can overheat and shut down (has happened in previous rocket flights), overall reliability concerns
- uncertain about changes, but probably includes:
- inner structures: change holders and mountings, drill tubes differently, changes to AV structure
- composites: tube changes
- avionics: get GoPros, connect to button through current BBC, disassemble GoPro and connect to its button, test its connection from GoPro to Bluetooth, change connector to button
