        I'm in!
        I figure resistance is futile...

        Now... about that LCR meter...

        BTW the Mouser shopping list adds up to $25 w usps shipping. The A1302 sensors are $1.50 while the AD22151 are more like $20 ea off ebay..

                    That leaves only three.

                    I multiplied the mouser order out by 11 and it comes to $191, no big savings there except on shipping which is hardly a consideration compared to sorting out all the parts and mailing off a dozen packages. I would consider having Elepro send all US-bound boards to one address via the most secure way we can afford and redistributing them from within this continent. It might make sense to split Canadian orders off from the US ones just to save the 2 weeks per border crossing.

                      Oh... is this a group buy? Well count me in then!

                        I imagine Elepro can get more boards made up if needed in another 4-6 weeks if there's lots of interest?

                              This sounds like a good idea.
