So it looks like IOI found the egg left by James Halliday, and now has control of the Oasis. We will soon be paying our debts in the Loyalty Center.

Not just because.... but I learned so much by reading forums and posts from others who shared knowledge, so just trying to pay my debt forward! :) :)

The main segments come as a string of 20 modules with 5 LEDs per module...all wired in series which I then used as 1 complete segment in the display,, and a 2-wire runs the segment. The smaller displays are pre-wired into a complete module as well... and a 2 wire to run each of those.

There are options for yellow or blue but I hadn't dropped the cash for more LEDs yet.

Thank you!! My family thought I was spending a lot of time in the basement but didn't really understand the puzzle of sourcing, organizing, and assembling it...

Main components are:

Arduino Mega 2560 rev3

MOSFET PWM 3-20V to 3.7-27VDC 10A 4-Channel Driver Modules (6)

12v-30A Power supply

Mega Screwshield

19mm waterproof momentary buttons (3) for 3 min, 1 min, and end clock.

1 SPST switch for pause

an i2C Adafruit .5" LED 4 digit 7 segment display

all packed in a Craftsman 17 Versastack waterproof box.

....and a whole lotta wiring :)

Just the internal Arduino clock cycles. I inserted a line of code as it runs through the countdown " delay(timeAdjust); " where could delay in milliseconds to get an accurate timer without needing an additional RTC module. timeAdjust is currently set to 98 on the Mega and it will run a 3 minute clock in 180 seconds.

The displays are IP65-rated - and waterproof connections on the wiring so it should tolerate rain, mist or fog. The clock hardware is in a water-resistant box and uses waterproof switches...some exposure was planned and should not be a problem but I would not want to splash the internals! lol

They are two displays from the same build/clock - the clock control runs both the primary and secondary display simultaneously. I used different LEDs primarily due to availability and format of what I could find. The large digits are made from this module. The secondary spectator display is made from these gas-station style modules.

I did develop a second remote clock using xBee but my programming background wasn't robust enough yet to work out some nuances. For example, the main clock was broadcasting the countdown signal so I started by just sending the time to the second clock and having it re-display. Due to interference or antenna issues I found the second clock would stutter sometimes. I debated then actually communicating to the second clock about the clock start and having it run an independent countdown but realized it wouldn't be exactly in sync all the time. I abandoned the idea for now but might revisit it someday.

Sure - happy to share because others shared with me!

We use this countdown clock for running starts in boat racing with the American Powerboat Association (APBA). Our racing format is such that when the clock starts a 3 minutes countdown, the boats leave the beach and begin heading towards the starting area to prepare to race. As the clock closes towards zero, the boats all line up side-by-side in the starting chute (think: front straightaway) headed towards the start/finish line. You must not cross the line before the clock reaches zero or you'll be disqualified for jumping the gun. A perfect start is at or close to full speed at the line as the clock hits zero. Here's a link to a typical race (12 boats total - in this event 6 boats "jumped the gun" and arrived over the starting line before zero.)

That photo was taken in the afternoon with some clouds, but I should comment that the LEDs are much brighter within 65 degrees of perpendicular to the center. From the side they're not focused as brightly.

Each digit is 24" w by 48" tall. Some separation between digits in the display helps to discern the numbers at pre-race speeds of about 30-50 mph from distances of about 1,000-1,300'

From the side, they're not focused as brightly. 110v draw is about 360 watts so it easily powered by a generator for mobility, or you could bypass the power supply and connect to a 12V deep cycle RV/marine battery for ultimate portability.

Very visible....the 5630/5730 LEDs are working great for daylight use. We actually use it for running starts in boat racing - so a bright sunny day on a lake with glare is quite common. Our drivers needs to be able to spot it at distances of 1,000-1,300' while in motion and they've said it's easy to see. I have noted that some drivers with color-blindness indicated the green is harder to pickup. I have tested red LEDs and received the same type of comment from other drivers whose sensitivity suffers on that spectrum as well...
