• Quick update

  Kurt • 06/12/2015 at 15:00 • 0 comments

  I had a few moments break yesterday from the rat race. I have made some good progress lately on the main DAQC python script. It is reliably pushing data to initialstate. (so much so I maxed out my free account) Tonight (friday cause i'm a geek) I am going to explore writing my own web based dashboard. One of the challenges I face is that Verizon want 500.00 up front for a static IP for the sprinter. While I believe every vehicle should have a web address, I am not willing to pay for something I can probably hack around.

  Updates

  • Enabled and tested onboard watchdog on raspberry pi.
    • I used a small heatbeat program to send a time-stamp to initialstate every 10 seconds. then left it run to see if there were any interruptions, and if it recovered from those interruptions. After 24 hours there were many interruptions however I do not believe any of them were reboots. I am going to tweak my code to include uptime info with the timestamps.

  
  Made the "focus" list of the items I am trying to monitor and control.

  • Monitor
    • Fan State (On/Off)
  • • Vent (Open/Closed)

  • Coach

  • Chassis
  • Temperature (Inside/Outside)
  • Humidity (inside)

  • Engine state (running/Not Running

  • Ignition state (On/Off)

  • Isolator state (Connected/Not connected)

  • Coach Battery (Charging/Discharging/current state)
  • Main Battery (Charging/Discharchingcurrent state)

  • Inverter (On/Off)
    • inverter Voltage (Analog)
  • Current (AC/DC)

  • 
    
  • Control
    
    • Isolator state
    • Vent (Open/Close)
    • Fan (On/Off)
    • Interior (dome) Lights (On/Off)
    • Interior (LED strips) lights (On/Off/Color) IR
    
    Last weekend, i built an isolator circuit

  It works, BUT in the process I smoked one of the isolators (not sure how) and I used an LED bar graph with an inop led. (probably smoked that last year sometime) I ordered some more isolators and got them yesterday (God I love Amazon prime) So, Rev 2 may get built this weekend.

  Oh, I also put together a gliffy with some common board representations.

  PM me if you want a link to the drawings on gliffy.

  Stay tuned...

  I have been logging my progress at www.magicsprinter.com however, I will be logging progress in both places now.
