Thanks Chris. The reason for the LEDs is that I am re-purposing a Netgear VPN Router case, which is steel and a bit more difficult to work-over than aluminum or plastic :-) The size of the case is good and a very good fit for this project. I may change my mind and go with a smaller case and one of the 2x16 LCDs I already have, but other than the clock, the rest of it was already there and seemed sufficient for an "at a glace" kind of display.
I guess I didn't know that the TBolt could be placed in NMEA mode. After posting this I did an RTFM and found a few answers in the TBolt manual :-) Russ Some kind of uP really is a good idea.
