Pendants

I don't want to start a beaten thread again. I wanted to add this if
anyone was interested. You can get a keyboard interface that can be
hook to switches or a matrix at
http://www.hagstromelectronics.com/modules.html , they are on e-bay
preatty reasonable http://cgi.ebay.com/ws/eBayISAPI.dll?
ViewItem&item=1748648281. Also I've been talking to a company that
makes membrane switches. If we could come up with a basic set of
needed switches and a desirable layout and had enough people
interested, I could get the keypads made for under $18, but the
minimum is 50pcs. Then you got a pendant that ties in to the keyboard
or you can unhook the keyboard all together. Just some thoughts.
