Pinecill LED mod - flashlight/headlights - dzid26 - 07-09-2022

I was spoiled by other cheap battery-operated irons that had LEDs so I decided to add a pair of spare 5mm white LEDs to Pinecil iron. I had them from a reverse backup camera and they were already prewired with a thin wire. 

- Vcc can be easily tapped from the leg of capacitor C8 or inductor L1.  (Vcc measured 4V for my Pinecil.)

- I added a 22 Ohm resistor to achieve about 22mA per LED:  (Rs = (Vbus-Vf)/If = (4V-3V)/20mA = 40 Ohm. )
- I positioned the resistor right above the tip core and glued it to the ground tab while avoiding making short anywhere (use insulation)

- LED anode (+) is soldered to the resistor and cathode (-) to the ground tab. 
- I drilled two small holes under the rubber sleeve for the cables and 3Dprinted a bracket to position the LEDs. Here is the file in Fusion360 (with Manufacturing Environment for slicing and final tolerance adjustments )

Hello, thanks for sharing this.  do you have a link to the 3D print of the front piece online somewhere?  thanks

It's there in the post - just have to use the download button at the top right of the page. Wink

There isn't a download button anywhere on the linked page. If you could post it I would appreciate it.
