Add LED on Your Cordless Drill

Installation very simple with few components:

-R470

-R100

-Zener diode 5.1V

-Capacitor 470µf 10V

-White LED

-Pcb prototyping

-Wires

-Heat Shrink Tubing

Step 1:

Solder the components on the pcb and before to shrunk the heat shrink tubing, do a test with the battery.

The capacitor allow to had a smooth light off.

Step 2: Mod Your Cordless Driller

Mod the case for add the LED.

Place the circuit.

The positive must be solder to the battery socket positive (blue wire). The Negative must be solder to the Mosfet (Source - pin3)

So if this is for 9-16V system, will the components be the same if my battery is 18V?

680 ohm should be perfect.
