Today I will show you something very interesting. It is not a killing robot or skynet (not yet).
It is a desktop ambiant light that use dead alkaline battery to power itself. This design can hold up to 15 batteries. It use a single joules thief circuit to power 50 LED!
The idea came when I was surfing www.yankodesign.com
and found this
The designer of that concept idea is Sungwoo Park and Sunhee Kim.
You are about to see how I made that lamp using common material and simple technique to build it.
I did try to make this lamp very simple to build, I though about all the people out there that don't have all the tools and skill to build complex stuff. I when with the moto "KISS" Keep It Simple Stupid.
I did a lot of planning before making the design. I tried to visualized the design in my head, I did some sketchup drawings, I made a lot of paper drawings. I sort of had only one shot at this and had to make it work the first time.
When I first saw this device, my brain started working and trying to figure out way to make it. These ideas where keep in my head. One month ago I saw the contest about environmentally friendly design. The first idea was to build a solar power ipod charger. A few second later I remember that energy seed and said, that is it, I am building a table top version of that! Back home I started drawing and taking notes about ideas. At the end of this intructables, you will be able to see those drawings I made.
By the way, I am doing a intern at www.solarbotics.com and I am having a blast! They have a laser cutter and I sort of fell in love with that machine, it really get your creativity going. Now I really want one :)
I will be a the MAKER FAIRE this May. I am presently in Alberta. I am going back to school (summer semester ) at the University of Sherbrooke in Quebec and then will leave for California!
PS - I really love yanko design because I get ideas and inspiration from that website.
ps- I guess I should say desktop lamp instead of table top and I should of said "Table top energy seed LAMP" in my title. You can't have everything right! :-)

I thought the deadline for the contest was MARCH 19 and not APRIL 19!
I work like crazy to get that thing done "in time". I have now time to make a other instructable! :D

1 x ferrite bead ( digikey part number HFB095051-100 )
1 x 1K resistor
1 x 2N3904 / 2N2222 transistor
1 x 1/4" mono chassis jack
1 x 1/4" mono plug
