I was waiting for someone to ask me this...Unfortunately...NO. (I am even exploring ways to encapsulate the circuit so as to prevent it being ripped off and copied, and deliberately obscuring components, etc. I have even got a couple of false traces on the proposed PCB for this purpose and possible tweaking if there are problems after PCB manufacture.
If I am to succeed in making this available and at a reasonable cost, some things, like the coil machine, will have to be kept secret. I have no doubts that the availability of the coil will inspire more knowledgeable people to develop their own designs and post them....so development will continue in an "open source" kind of way as exemplified by this thread.
I have thought about this, and have an alternate design, without the limiting and drive function of my circuit that is likely to be simple, yet an improvement on the fetzer/ruby. The basic ideas were tested and so could be mocked up for the public. This could also be a side project, since I am buying parts in bulk, to make a cost effective "kit of parts" for people to DIY this design.
Good point, and I know Col was thinking of doing something similar with opamps as a DIY standard circuit.
Sorry...that is the state of play there... Given the problems and expense many have run into acquiring the components and getting the circuit running, I think the purchase of my pre-made design will be preferable. I am aware that I need to compete commercially, not only with the other makers, but the DIY'ers too.
Hope you understand...pete
I totally understand what you mean. I realize how much work you've put into this, and I understand how pissed off I would be if I did all that work then some little punk makes the same circuit and starts selling them under his own name. I guess I'll build the fetzer/ruby, then tweak it myself. An alternative design would probably be cool as well. And I see that the most prominent part of the diy thing would be designing better drivers. If you were gonna have people test them I'd be more than willing to be a beta tester and give a lot of feedback. Also I think a thread is in order for all the layouts and picture of people's new drivers, sustainer guitars, designs, concepts that have been posted all around this thread. They're all really nice and helpful but hard to find. That's all IMO, but I think it'd be useful (or a table of contents).
Thanks anyways
