Energy Seed: A Yanko Love Story

Listen, we all love Sungwoo Park here, don’t deny it. There’s been more than one satisfied reader here on Yanko when it comes to Sungwoo. But this time, the reader took an extra step and became an inspired advocate for action. This reader cum designer, Jerome Demers, took the Sungwoo Energy Seed concept and made it DIY and desktop sized. Don’t you want to play along with the “dead” batteries too?

The parts used to make this contraption are intuitive: metal plates, plastic to hold the batteries in place, margarine container for the base, but here’s the important part; the circuit ingredients:

Parts you will need:
1 meter of white and 1 meter of black wirewrap wire 30 or 28 gauge
1 x Ferrite bead digikey part number 240-2145-ND
40 x High power LED
1x 1K resistor
1x 2N3904 or 2N2222 NPN transistor

These are put together to make what’s called a Joule Thief. This is a fun and amazing little amalgamation that makes use of left-over juice in batteries that you’d otherwise throw away because they’ve got little-to-seemingly-no power left. They almost always have a bit of juice that you can access using the right formula. Hood a thief up to an LED light, and WHAMO! You’ve got a nice little environment helper.

Check below and at at Demers’ Instructables entry for further details and instructions. Watch the movie for words from Demers himself.

The most important part of this story is, of course, that he was inspired by a Yanko entry. Yanko! Yes, Yanko, bringing the conceptual industrial design world together, one post at a time.

Thank you very much Jerom Demers! Well played!

    ive got to applaud the fact that he is a do’er rather than just a renderer. its becoming rare these days. it proves the process in the idea. i have been criticised before for shooting down people’s dreams and that without dreams we would not have such diversity of products.
    However there is a phrase, design is 1% innovation and 99% perspiration..! Here we have seen a little of the perspiration.

    Good to see people showing initiative. I love the chaos in the background of the vid!

    kudos to you Jerome! Great job turning concept into reality. I have supported and talked about this on Yanko before but haven’t taken the time to do it myself, aside from my own ideas. So thanks for giving it a kick start. I think more DIY’ers should bring Yanko concepts to life. Like the camera boomerang idea, or flying stick idea. Thank you thank you!! Awesome job!

  • Wow~!^^ That’s great~! Thank you for your interest.

    In the last picture the circuit looks like a bird head :) (upside down) 😀
