NodeMCU BT Wrist Hand Flame Flash IDK

Poof!

Similar projects worth following

IoTkazam!

There is nothing up my sleeve .. save for this giant WIFI and Bluetooth enabled flash paper igniter.

With a sleight of hand .. a touch of the screen .. and poof.

No one is paying attention any ways bcz they are looking at their phones too.

Notations

1. Prototype .. read the room.

2. NodeMCU (wifi) + HC-05 (not BLE) + TIP120 (relays) shd be a maker board. "VijeCU"?

3. Bcz the glow plugs are simply resistance wire coils, they are driving current and grounding the circuit. Thus, per this particular purpose, we must use relays .. which is a s/o/b after having had confidence in the transistor model.

4. WTH happen to those Radio Shack drawer 'mini' 5V relays?!

5. Isolate.

6. "Fallen Hero" by Emily M. Klassen

    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 Miller01/28/2019 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?

I simultaneously want to see the video, and don't want to see the video...

Ooof, that kind of makes me queasy to see those so close to your wrists/palms... invest in burn cream ;-P

The sweat from the stress of the thought of it exploding on my wrist acts as a natural flame retardant. https://cdn.hackaday.io/images/2220111549149073209.jpg
