[time-nuts] time-nuts Digest, Vol 109, Issue 57

[Didier Juges]

Looking at the high price (and closed software) of what is currently offered, I have been thinking of making a kit of my GPSMonitor (see KO4BB.com)

I think I could sell an assembled and tested kit with a 2x16 char display for $60 or so if I get 50 people interested.

Of course, the source code is free. You can build your own using info on my web site.

If anyone is interested, send me a private message.
