Description

I had these parts (led, lens, IC) from some time and I decided to put them to good use. I designed a small PCB for the charger and used a 2W resistor to limit the current through led to about 100mA. Glued everything together.

Materials and methods

- Cree XP-G LED
- Ledil lens
- MAX 1555 single Li-Ion charging IC
- mini USB connector
- 18650 Li-Ion cell
- rocker switch
