  Technology students at a local private school had a go with bluetooth and wifi enabled dousing distances with puffs of flames.

  Lesson in futility ... and a reminder why I hate fancy products.

  Needs perhaps just 1 more battery .. to which then I no longer care .. having reached my official project-tolerance-epoch.
  

  Those with patience, money and steady soldering hands are welcome to venture onward.

  After a complete tear down of the TIP120s from the board believing they were wired wrong -- they were not -- and after some wild testing -- it appears that the glow plugs being a mere resistance, are grounding the entire circuit.
  

  Now .. permitting that I am not wise in the ways of electrical engineering .. this will require all my internet-ing slash begging for assistance skills.

  Following this .. will more than likely transition to 2N2222 NPNs for the switch bcz they are easier to manage on the scale of the project.

• NodeMCU + BT + (3) TIP120 Shd be a thing ...

  Vije Miller • 01/28/2019 at 16:45 • 0 comments

  For any entrepreneurs out there .. this .. this shd be a thing .. but refined of course.
  

  NodeMCU + HC-05 Bluetooth Module + 3 TIP120 (60V Relays)

  Offers WIFI and BT IOT capabilities for up to 3 low voltage .. things. A veritable maker's paradise.
  

  Point is .. a large majority of my projects and other's-maker's projects would embrace a primal integration of these elements in to a refined minute board. None of that learning complex AT cmds for ESP or BLE non-sense .. #MakeMakeMakeAgain
  

  Hey, @Benchoff .. HaD branded board?
