Santa got an upgrade
His new Mediatek brain (NEXX WT3020)
Lucifer in disguise..

The LED is configured with RX as trigger. The LED GPIO is linked to the some contact that triggered the HO HO HO sound, it also make santa walk move his arm to ring the bell and blink a LED in the candle. A lot of action being triggered by just one GPIO.

The NEXX is configured with 4 X-mas themed SSID's And everytime someone comes close who has WiFi turned on on his Phone RX gets triggered on wifi negotiation, and Santa does his thing, In other words VERY annoying... All powered with an old ATX PSU (one that has 3V)
