Let your cigarette lighter wearable
As a smoker, how cruel it is if I lost my cigarette lighter! I used to think how wonderful with a wearable cigarette lighter. So it comes into being.
From the picture, we see it is a kind of big, but anyway I like it! The cool lighter is attractive. Different from traditional cigarette lighter, it kindled by arc, controlled flame by bottom-touch. The touch bottom uses the function touch from GPIO itself of FireBeetle Board-ESP32. What’s more, it is a watch too.
Hardware
Hardware in need:
High-voltage booster coil for Arc lighter ×1
NPN Triode×1
51Ω Resister×1
1KΩ Resister×1
1N4007 Diode×1
Powerful Triode×1
ESP32 WiFi & Bluetooth Dual-Core MCU Module×1

Schematic and drawing, shown as below
Soldering electronic components to FireBeetle Covers-Proto Board according to the image and connects a control pin of lighter to D3 of FireBeetle Covers-Proto Board by wire. You can also connect to D3 of FireBeetle Board-ESP32 directly, for the compatibility of FireBeetle series is great! Connecting Vcc to Vcc (Covers-Proto Board), GND to GND (FireBeetle Covers-Proto Board).
P.s I am so sorry if you do not understand the drawing. 1. Connecting touch wares. FireBeetle Board-ESP32 has touch function itself and I chose T3 (A4) and T5 (MCLK/IO12) to be connected. (If you are confused about the reference pins, FireBeetle Board-ESP32 user manual could help you.)
2. Connecting LED light board, FireBeetle Board-ESP32 and soldered expansion board, shown as below.
About connection, I put pin and female pin together and put the lithium cell between them.

Firstly, let the touch-sensitive wires go through the bottom assembling holes reserved before respectively, shown as below.

Heating screws and spring washer with a heat gun to fix them to crust easier and more convenient (this is the touch bottom).
Caution: Do not touch a spring washer by hand. Fix the spring washer to crust, ensuring the connection between plate and wires.
Caution: The two output wires of high voltage coil should go through the crust.
