They have 'em already mounted on daughter boards for $1.64 (plus a buck shipping) on eBay: http://www.ebay.com/itm/400503978923 I'm not sure how they manage that, but it would be easy enough to solder those to a board (or solder on a female header and just plug it in). - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
