As mentioned before, we will now proceed to change out the LIDAR USB sticks every ops shift. The procedure for doing so is as follows:

  1. Verify number on the USB stick to the specific LIDAR  Raspberry Pi (1+2:UE, 3+4:UW, and 5+6:D) - 2/17 Ethan told me it doesn't really matter which USB stick gets put in which lidar, as long as all the USB sticks are the same size.
  2. Remove and replace USB sticks on the minutes ending in 2,3,7, and 8 while trying to avoid 1,4,6,9 because the card reads every minute ending in 0 and 5
    1. Use a reliable clock with good gps time when doing so
  3. At D, the lidar pis are not in the DSM box–they're in the beige box hung on the boom near the DSM. There's a screwdriver taped inside the door of the power box you can use to open it.
  4. Probably a good idea to check with Ethan before a visit, in case he has specific directions about specific lidars.

    When Ethan says ‘SD cards,’ what he means is usb sticks.
