Doesn't Decware offer plans/kits?
BTW Steve has gotten burned more than once (professional review, various forums) due to outlandish claims, his lack of "mainstream electrical knowledge", and his off beat/lonewolf approach. So many see him as "not playing well with others". But he's a couple of big steps better than a certain wild hillbilly whose Dad builds speakers for him to sell.
Personally I think the world needs more "individuals".
