Electrical Layout (Summary)
18V battery → rocker switch → LM2596S (IN+/IN−) → 5 V output → USB-C → LED
The metal plates act as power contacts between the battery and the electronics.
Setting the LM2596S to 5 V (using a multimeter)
1. Connect the 18V battery to IN+ and IN− of the LM2596S
2. Do NOT connect the LED yet
3. Set the multimeter to DC voltage (range ≥ 20 V)
4. Measure OUT+ and OUT−
5. Adjust the potentiometer with a small screwdriver:
clockwise → voltage increases
counter-clockwise → voltage decreases
6. Set the output to exactly 5.0 V (4.95–5.05 V acceptable)
7. Recheck the voltage
8. Connect the LED only after the voltage is confirmed
Printing & First-Use Notes
During the first ~100 usage cycles, the lamp may feel slightly stiff.
This is intentional and improves durability and long-term robustness.
Recommended printing materials:
PETG or
ABS
Important Notes
Incorrect voltage may damage the LED
No built-in protection against short circuits or moisture
