Please don't rip off this guy's design for your own profit, and please don't post up the schematic. This guy isn't getting rich off such a small market, he's an enthusiast selling a clever product at a dirt cheap price, pretty much for the fun of it. Why steal his design to save a few bucks? How would you feel if you were him? It'd be different if he was charging $300 or something, but come on.
I'm an electrical engineer, I could buy one of his and have the design figured out in about 5 minutes and start building them. I'm not gonna do it, I don't have the lack of ethics the Chinese do.
By the time you build and troubleshoot your own, how much time are you going to have in it, especially if you're not a EE? Probably several hours, maybe you get to push the bike home sometime when your homemade version fails. Give the guy a break and support his innovation by buying his incredibly inexpensive and clever CDI.
Not flaming you but I do disagree that it would be ripping off his design. If you are building it for yourself, not for resale, then there is no problem. Now, if I was planning on making them for resale at a profit then I can see an ethical, and possible legal, problem with that. However, that is not my intent and being here on KDXrider, the best place to sell such an item, you guys would know if anyone was trying to screw the guy over.
Anyways, I have built many electronic projects from known commercial designs over the years. As a musician this is done all the time for effects pedals, pre-amps, and even amplifiers by regular people. If it wasn't legal to do so I'm sure companies like Ibanez, Morley, DoD, Marshall, etc would put a stop to it. Also, think of the majority of products on the market that you own. Do you seriously think American companies (forget China!) don't buy their competitors products, reverse engineer them, and implement parts of the design, or improved versions, into their own product? Sure, they change it just enough to not legally infringe on the intellectual property rights of the other company but come on! You honestly think Kawasaki, Honda, Suzuki, and Yamaha, haven't done this? How about Ford, GM, or Chrysler? And the list goes on! It is a common and accepted practice throughout the world since the dawn of time. The only reason everybody singles out the Chinese is because they are blatant about it and copy a product right down to the user manuals and packaging which is unethical!>QBB<

Uh, it looks like that is the case with the original version as well since we have already heard of one failure from gregp
. I personally would like to see where I can improve upon it like osobad
has and maybe my soldering skills are just a little bit better than the guy would made them!
