This Multi-LED Joule Thief is designed to drain that little extra bit of power from your used batteries while providing usable light. It can also be used with fresh batteries for up to 100 hours of continuous light. This circuit is an upgrade of the popular Multi-LED Joule Thief. The hand wound transformer has been replaced with an SMD common mode choke that is also used on the Joule Thief Candle. The 17 bright LEDs have been replaced with 6 super bright SMD LEDs, there may be less of them but they are brighter. A micro SMD slide power switch replaces the 3D printed switch from V1 and is more conveniently located.
AA battery not included
Thanks for your interest but I’m sorry I don’t ship internationally due to the cost and hassle for such a small item. Since Tindie will keep pestering me every time someone outside the US wants an item I placed a ridiculously high flat rate price for all international shipping to reduce the amount of messages I get. You are welcome to try to make some yourself, files are available on GitHub. Thanks for your understanding.
