LEDs, 7 seg display and alpha display
Adafruit backpack modules (well, standalone modules).
Using i2c and the adafruit API makes it simple and easy.
The center module is a GPS receiver; $20 on ebay. speaks 9600 TTL serial, standard ascii '$..*,HH' NMEA format.
the 7segment on the left displays local time and the alpha on the right UTC.
I'm also comparing the look of the two, if the data to be displayed is pure numbers and no alpha. so far, the pure number use-case wins big on the left display and not so great on the right. if you have to display letters, the right is your only choice, but if you only display numbers, the left is much better.
photo note: somewhat challenging since the display is very bright. my color balance is way off, but I did what I could in post. in a real system, the display modules would be behind a red or tinted plastic window and the contrast will be much nice, hiding the unlit segments.
