#91 A WiFi battery powered firework igniter

Since I used low voltage with nichrome wire using LAN (RJ45) cable was not an issue. However with the next version I will solder a female RJ45 socket to avoid the hot glue tsunami… 🙂

Creating a WiFi fireworks igniter with a backup LiPo battery.

With December just around the corner I wanted to design a remote fireworks igniter working on WiFi and battery power.

The board will use mosfets as switches to nichrome wire which will heat up and ignite fireworks from a safe distance.

Before completing the PCB

The idea is to have the system self contained with the ability of remote control via a WiFi AP using an ESP8266 12F
