John absolutely DOES give credit to MAKE in the video.  Even identifying the issue number.  The editors at DesignNews who did the write up on what the video was about are the ones who failed to give credit by simply stating "a magazine". 

 

So in short, 15 year old John does it right.  The professionals who's job it is to get these things right are the ones who screwed up.

Hi John, I'm curious why you didn't identify "a magazine" as Make, where Steve Hoefer's instructional article for the "indestructible LED torch" appeared. At Make, we give credit for things like this. We remain admirers of Design News. Mark Frauenfelder Editor-in-chief Make magazine

Very Cool project.  I wish had your motivation and drive at fifteen.  The internet would have been very helpful too.  Recently I discovered an open source program called "Fritzing" where you can graphically assemble a breadboard version of your circuit. Then after some frustration create files to order a PCB or boards.

Jason I agree with your sentiment. Not every good idea comes from outside the box and sometimes it is wise to rely on experience.  Not all experience results only in total nay saying. Sometimes it saves time. If John is not sure of the validity of the advice, then he should not abandon his plan, but if you are talking to an expert in a field and he can point to numerous failures of a particular method, why not utilize that information?

The Original Patent Apparatus per request...

This was done prior to modern day Computers and Devices that transmit power 'Wirelessly" - it works well, and is still in use to this day for the intended
purpose of the Patent. It was brought about by a "need" requirement - which
is the "Mother" of the purpose for Inventions....

foxzzy- can you post the Patent #?  I like to read patents (weird, huh), especially pertaining to wireless energy transfer.  I guess it is the old Tesla coil enthusiast in me.

Well, you have used a method that was patented more than 20 years ago by myself to transfer energy wirelessly. I guess it shows that minds do work in some kind of collusion when the need arises.

Thanks for you suggestion of more coils, alzie.  I have just tested a new version with a TIP120 in place of the 2n3906's, and about 5 times more turns on the primary.  I currently get about 0.02A at 10V out, which is more efficent than before, which was below 0.01A at 12-14V.  Once I get a Jameco.com order, I'll try to match the reasonance of the coils for efficency.

Just so everyone knows, the build instructions will be re-posted to include the schematics.

Congrats John and I think you are the odd among the youngsters. Use this forum for more interaction with experts and hope you are able to do more design and assembly in near future. All the best.
