I think that there is plently of interest. Trouble is everyone wants something different. Brooke's LCD one looks good, may be he will finish it off. Just the 16x2 LCD, 1 PPS input, 10Mhz clock. Then add IRIG in and out, GPS update, serial output to drive a sipo shift register to drive 7 seg LED's, NTP, Battery back up.................... Some of the published micro based designs are a bit kludgy. Robert G8RPI.

But I always wondered why as long as I have been on the list no one has developed a LCD or LED unit using a PIC or other controller chip along with a board. Is there no interest?
