A Basic touch activated under-shelf light bar I designed - using what electronics I had

804040 Li-Po Battery, 3.7v 1200mAh
TP4056 Charging Module (One with Battery OUT)
TTP223 Capacitive Touch Switch
LED strip (I used a simple Warm Light strip with only Pos/Neg leads)

If the TTP223 is glued correctly, the switch should still work through the plastic,
Be sure to secure the TP4056 so it does not move out of the way when you try to connect a cable to charge

Since the light is not meant to be on while charging - there is no extra protection such as a Schottky/Zener Diode. if you feel this is needed feel free to add it, correct me if im wrong

Just used velcro to stick under shelf
