As mentioned before, we will now proceed to change out the LIDAR SD cards USB sticks every ops shift. The procedure for doing so is as follows:
- Verify number on the SD card 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.
- Remove and replace SD cards 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
- Use a reliable clock with good gps time when doing so
- 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.
- Probably a good idea to check with Ethan before a visit, in case he has specific directions about specific lidars.
