Maker of TinyTrak controllers and MicroTrak transmitters
Purchased way back in 20 Aug 2010 and tossed into a "future projects" box. I got a TinyTrak4 controller kit and a MicroTrak MT8000 8 watt transmitter.
2013-Sep-03 I am thinking of using the TinyTrak+MT8000 with a Garmin GPSmap as the NMEA data source, with the Garmin Power/NMEA cable. Then I can carry it on a bicycle.
