This Joule Thief takes 0.75V and charge up it to 2.1V without load and with 10-20mA load to 1.8V.
- R0805 1K
- C1206 10nF
- 4700/25 (uF/V)
- 2V4 and 5V6 zener diode
- 2 Wago508 terminals
Step 1: Desing PCB in Eagle CAD.
Download my eagle desing and just print. I used 4 th compoments and other smd.
Step 2: PCB
Classic toner transfer.
Step 3: Soldering and Winding Coil :D
I used 30cm of white and blue wires and wound it. First solder smd parts and then th.
Step 4: Testing
For me it works. Voltages depends on turns and ferrite size.
