Attached the mount onto the arm last week. Currently, the lidar and OFS are attached and wired up thanks to Mena Azab . (The wires are zip-tied to the tube so they aren’t flying all over the place when the drone is flying)
Some things to improve upon:
Slight wobbling because hole for the tube is a little big. Just need to reduce the hole diameter and reprint to find the sweet spot.
Might be challenging to insert/remove the Clevis pin because it is directly under the tube (but it wasn’t too bad when I tried it). I can redesign if it’s too inconvenient but I don’t see it being a huge issue. If everyone thinks I should redesign so that the clevis pin should be perpendicular to the tube length-wise I could but there’s a high chance it adds more weight to the mount ;/
Need to add more space for the wires (it still fits but would be nicer to have more space) and the FPV camera since the plate is kind of close to the tube.
There was a concern about the leg appearing in the CV camera’s field of view (which would affect object detection stuff) but I tested this with the autonomy leads and the legs don’t appear in the CV camera (LET’S GO). But not sure if the leg will appear in the FPV camera (also which subteam should I inquire about stuff relating to the FPV cam?)
If anyone has suggestions on how I can improve the mount please lmk, would love to hear your thoughts!

Neel Patel Parker Lawrence-Valeriani Please write update!
Neel:
General layout idea revised
Navigation light static red on left, green on right
Beacon lights, red strobing all 4 corners for 360 visibility
Anti-collision lights, white strobing lights all 4 corners for 360 visibility
will need to discuss with mechanical where they could be placed near the motors
Possibly in a position so wires can go through the arms
any concerns with soldering directly to LEDs
Power architecture
Spec LED’s that take 12V and total less than 2 amps
Possibly use the PDB 12V which can supply 3A
currently only see the VTX which draws 250 mA
Could also use another BEC is required which can supply upto 12V, 5A
LED Spec questions
what distance of visibility do we need day/night, does this need to be researched?
What waterproof rating is required (if required)
Parker:
Utilizing a 555 timer to achieve strobing
Used in its astable configuration so it’s functioning like an oscillator
Duration of ON vs. OFF time is easily chosen by selecting resistor values (ON time must be less than off).
Questions
How long do the ON and OFF states need to be? (set by a potentiometer possibly)
