2023-11-01 LED Controller Sync

Attendees

Proposed Solution:

Constraints:

• Visible at night and daytime (very bright)

• Well integrated

• Each light must be visible from 120 degrees,

  need to go on ends of motor mounts and below/above arms?

• 4 LEDs (red, potentially blinking) one on each corner is the absolute minimum control requirement.

  • realism for airplane:

    • white strobe light (pulsing?), visible 360

    • beacon light, visible from 360 around. red.

    • red on left, green on right, white on BACK. static.

      • ‘don’t need white on back probably'

• also need to decide reflectors - these can be picked in tandem with LEDs, as adding reflectors may eliminate the need for a stronger LED, etc.

• EE global constraint should be weight

  • save weight instead of add more brightness (if the tradeoff is reasonable)

Things to Research

• How will we connect to LEDs (Connector/Solder/Headers)

  • Most likely solder

• Need for input for Pax??

  • No input for pax required

• Where are we getting power from(Usually 12V) (search through architecture doc)

  • PDB - 3A

    • vtx draws 250mA at 12V

  • BEC - 5A

• Ways to achieve variable Strobing/Blinking (555 Timers) (Parkers on this!)

  • https://www.youtube.com/watch?v=b_HDwIlMLdQ

• What distance do they need to be visible from

Suitable LED strip lights should be chosen via similar setup to Decision: Type of Rangefinder for Obstacle Detection page. Can include neopixels if desired, but please compare individual part numbers.

Project Owner Availability:

@Neel Patel : 2-5h hours a week

@Parker Lawrence-Valeriani 5-10h a week - better idea of availability after midterms.

Agreed upon timelines:

1. Architecture plans for next AEAC meeting (research and decisions)

2. Order components first week of November.

3. Full working prototype for end of November.
