  • CORA Digital Clock

    After a generous grant from the APBA Historical Society, the Columbia Outboard Racing Association has completed development of it's LED digital starting clock. It has performed flawlessly for four races. I have attached pictures of the clock in action at our most recent race.

    The clock itself consists of circuit board panels that create 3 36" high digits using red LEDs that are visible at extreme oblique angles. Red lenses are used in front of the LEDs (within 1/8" to 1/4" of the LEDS) to maximize visibility in bright sunlight.

    As far as price, you will need to contact Terry at Alzatex (alzatex.com, 503-642-9693). You can see the price ($3,250) for a basic model of this clock here http://www.alzatex.com/products/cata...p_dsp3600b.php , as the DSP3600b is pretty much what we are using.

    This price would not include the bullet-proof plastic casing we had built (and donated) by a third party, the lenses, the remote display for the scorers, the boat-racers proof connectors, and wiring for three separate segment cases (easier for us to haul to haul 3 2.5' X 4' cases than one 4' X 8' case) that the CORA clock has.

    Again, without the generosity of the APBA Historical Society (a big thanks to Patrick Gleason and Steve Greaves on the grant app and sales pitch), CORA Commodore Lee Tietze, the Newberg Boat Club, the persistance of Ken Kaiser, and numerous donations from CORA members and other Region 10 racers, this 4-year project would not have been completed this successfully.

    These photos were shot from across the course, zoomed in for an "on course" perspective. This clock can easily be read from at least a quarter-mile, even a half mile away.

      Maybe I coulda got a start at Silver Lake if the CORA clock was used. I wasn't the only one that had a had time picking up the clock from the other side of the course...I previously thought the digits were too thin on the CORA clock, but not anymore. Incandescent bulbs are hard to read from 800-900 feet away with spray in the air.

        Ken Kaiser has offered to bring the clock down for the 2010 Stock/Mod Nationals at Oroville. Stay tuned.

          How does the clock display the countdown from 5 min or 3 min green flag to the one min white flag?

                I had the same problem with the clock on Sunday. Could not tell that the clock was reading 20 sec. To me it looked like 40 sec left. Saturday was better early in the morning with the cloud cover. It is terrible in the bright sun for these old eyes.

                  The pictures I posted were taken in direct sunlight. The digits don't wash out. When the display goes from blank to 3:00, it really catches the eye (especially old ones like mine ), even from across the lake.

                  Kaiser has made the same offer to SOA regarding this clock that he has made to Region 11 for Nationals. Perhaps SOA would like to take this clock for a test drive at Lawrence?

                  An added feature is that it runs on 12v power. This allowed CORA to convert the entire barge (running TV/VCR/camera on an inverter) to 12v - no need for a generator. The barge crew doesn't have to listen to an shout over a generator all weekend. We use a storage battery from a forklift, and trickle charge it over night, though we have run full events on a single charge. The addition of a solar panel charger would allow one to trickle charge while in use during the day.

                          Mike, you may want to ask Lee Tietze about this clock as I know he has been involved (at least financially) in the building of the CORA clock.

                            I really really hope you were having a beverage when "fluid" came out your nose...I wasn't trying to be a smartass, I just tried to be accurate answering the question.

                              Great clock............

                              Our digital clock was built here in Region 4 20 years ago! Maybe someday all our races can have them.
