May 2019

  • May 23, 2019 - Adam adjusted the sync pulse. Triggerwidth is now 53us. He also provided instructions on how we could asjust it ourselves in the future (attached). This fixed the issue that was leading to the lidar software rebooting the laptop.
  • May 20, 2019 - Laptop rebooted nearly continuously 2pm to 6 pm.
    From Adam (May 22, 2019)
    The issue appears to be the same as last time where the sync pulses are low and taking longer 
    than our timeout period to collect enough pulses 
  • May 9, 2019 - Started using automatic Python script relying on PyEphem to open/close shutter at sunrise/sunset.

May 2018

  • May 26-27, 2019 - Door's Open (MiniMPL area closed off, but many people on 15th floor).
