Vilson, I'd be happy to send you a board. Also the Eagle CAD design files for it are posted on the eChucK forum Eagle CAD is freeware and cross-platform to Mac, PC, and Linux, so that's why I use it. Well, actually if you use it for profit you have to pay for it, but for us hobbyists it's free. The maximum allowable board size is small but sufficient for many small projects. If you download the files you won't have to reverse engineer the board but I'll send you the last remaining board anyway. It's nothing special, but it will give you the idea of what's going on. Oh, and if you prefer I have one board that's already chopped up into little boards. Please email me (inventor-66@comcast.net) with the mailing list and your preference as to which board you would prefer me to send (whole or chopped up). And especially thanks for participating in the project, I'm sure it will be wonderfully educational. Les Mark, Thanks for the encouraging words. I'm beginning to realize that having these first four boards made was primarily an exercise in learning Eagle CAD and working with a board house as a hobbyist, plus more importantly it has provided sort of a focal point for getting the ball rolling on the eChucK project, even if we never use these first boards in practice. It helped make people realize that the project is tangible and real and ever so slowly gaining momentum, etc. The cost at the board house I used was $100 for four boards, 3" x 4" in size. That's double sided with solder mask and screen printing, but not chopped up into little boards. So that works out to about $30 each including shipping. Not cheap, but acceptable I suppose. I hope you enjoy your perusal of the eChucK forum and please feel free to post a message if you like, the more people who chime in, the more excited other people will become. Enjoy. Les
