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. #MillennialMagic
Ingredients NodeMCU 12E HC-05 Bluetooth Module (3) RC Glow Plugs (3) 5V Relay Modules (3) AA Batteries CR2 3V Battery Flash Paper
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 gnd the circuit. MOSFET was attempted yet interference troubled the MCU+BT. For a more immediate impatient solution, we must use mechanical relays. Huge, bulky, module, relays...sigh. 4. WTH happen to those Radio Shack drawer 'mini' 5V relays?! 5. Isolate. 6.
