  OK a few changes along he way so far.

  > Added a reset button

  > Added a on/off button (push)

  > Shorter cable for the Antenna

  > Added a button to toggle between LAN & Tethered WiFi network. need to manually connect to the phone via Hotspot, but generally stays up for the duration.

  > Scripts added for each button to perform function

  > Added case adapter to plug in charging cable (micro USB female to Micro male USB)> Added a power light LED (green)

  >Added Autogain adjuestment in again as not getting flights overhead, see if that helps.

  < Still awaiting GPS Unit

  < Awaiting other case/cable adapters to can charge other devices from Powerbank.

  < Ordered a Raspberrry pi Battery pack hat to replace the PowerBrick, will reduce the weight but also the uptime.

  < Need to add a manual on button for the (current) battery back, to turn on without opening the case all the time.

  < Decoding the data stream, some excellent infoirmationonline

  < work out how to get the GPS USB to talk to the Pi/FlightAware.

  Enclosed project in a plastic Tupperware box for portability. Attached mobile phone to exterior (Wi-Fi connected to Pi).

  Issue with visibility in bright sunlight, should be able to solve with a small shade hood. 
  Battery test. Achieved about 12 hours of (no gps yet) battery use via the 10,000mah battery bank.

  Aerial location was fine but needs better a mounting. Will 3d print a bracket.

  Also have an auto gain script running. (Hang over from it’s past more static life). Will reset & deinstall so I get a better sense of it the real range.

  Having GPS will improve readability (current location is static, so altitude was better indicator in this instance) when using the table

  Discovered that the map and table need to be separated. Too small on the mobile to see both. Investigate hack of web page to separate. Also increase font size on table and minimum set of fields. 
  

  Attached power switch to Pi, added scripts for shutdown. Need to add a reset button as well.

  Started on decoding the ADS-B signal. Can be viewed on port 30003. Excellent primers on web.

  Added small aluminium heat sink to plastic case of FlightAware dongle and to raspberry Pi USB hat as both getting extremely hot.
  
  Could add a smaller battery bank to top up power to mobile phone so that both have approx 12 hour life. Will comfortably fit in container and small hole for charging cable.
