Important Aurora News!  August 13, 2021

There is so much news, I'd better break it up.

A:  The Aurora Clocks are back in production, but there are a lot of back orders to fill.

B:  Angie Pimentel is going to be repairing and making new Aurora & Prisma clocks at AP Clocks in Santa Rosa, CA.

C:   Barry Gamble's future plans.

First the best news. The repairing/rebuilding of Aurora & Prisma Clocks will likely continue for many years.  

Prisma's are built and shipped in 4-7 days after your place and order.

Angie has received new cases for new Auroras, and assemble has started.  There are about 31 allocated to customers who placed a deposit.  And there about 10-12 others who asked Angie to call as soon as they are available. You can call Angie, at 707 694-7719,  and have your name added to this group in date sequence.  There will be about 145 more made over the next year or two.

But now some bad news:

Here's the story.  For 60 years one company, Hansen motors,  has been manufacturing the motor and "special" movements for the Aurora.  Hansen was bought a couple of years ago by Electrocraft and the new owners have decided to discontinue production of all clock movements.  The movement is a gear-train that moves the hour and minute hands.  They will continue making the motors which will allow us to keep doing repairs for a long time.  And some good news,  95% of the movements never fail even after 40 years.  They just need a little oil every 25 years.  So that's the "movement news", but there is more....

Once those 145 are sold, production may sadly end.  These clocks have been in production for over 52 years and are still so loved, that this is a great sadness.

For your reference, since new Auroras are becoming scarce and material cost inflation has been ridiculous lately, the price will rise as Angie's limited inventory disappears over the next 12-24 months.  She can't tell how long they will last because some customers will buy and store for future presents.  Back in 1981 one customer bought out my entire inventory of remaining Model I, "Dot Clocks" because he knew they would soon be clock collector's gems.

And speaking of the Dot Clocks,  if you own one you should call me for a chat, especially if you have one that's not functioning.  I have been doing a labor-of-love project.  The world keeps changing.

Angie Pimentel has been building, repairing and doing all the paperwork for all Auroras & Primas at ChronoArt for the last 3.5 years.  That portion of ChonoArt Clocks is now her's.  Her business she has named AP Clocks.  She is having some fun with the name.  Is it Angelica Pimentel Clocks, or Aurora Prisma Clocks?  She'll never tell.  But, I'll bet this anecdote will help you remember the name.

AP Clocks will just be a few miles away and I am sure she will be back at ChronoArt every few days for a year or two.  Using some of my equipment until she can afford her own, and helping me enjoy my passion.

So what will I be doing?  Working a little less.  Spending more time with wife and friends.  And.......

I love the creative process of designing. Plus, it's fun figuring out the best way to manufacture.  And there's fun in chatting with customers.  And with digital art clocks and I have  ------ A LONG DREAM LIST.  Here's a Binary Clock example of one of my dreams.

  

I am Mr. Persistent, a.k.a. Barry Gamble. 

Take care my friends.

Aurora Clock

New Aurora Clock by ChronoArt

News for December 4, 2020

Announcing new and improved LED lighting!

The microprocessor controlling the LEDs now has a     new color cycle.  First it spends about 45 seconds in colors similar to the original Aurora, then it cycles to:

Deep Blue and  Toasted Red colors

Sunset Orange and Hot Pink colors

Sea foam Green and Aqua colors

Yellows will then start over, but the colors will be slightly different because the second hand disk will have shifted by 90 degrees.  Joy in Colors!


The YouTube video below shows how the colors change as time passes. It displays the older version of the LED lighting; the new LEDs show more vibrant colors today.

I believe the video is an LED clock we repaired.

We did not make this YouTube video.

The AURORA CLASSIC is an updated version of a beautiful clock from the 70s. The Aurora has been in production for over 50 years. Its classic contemporary design was honored by the Museum of Modern Art. 

What's so special?

A very contemporary case, beautiful colors, and --- a mystery! There are continuously changing colors and surprising color shifts as the secondhand disk overlaps the minute & hour hands. The clock will continues to play tricks on you too: As you walk around watching the clock, you'll notice the colors change depending on your viewing angle. Inside the clock, you'll see a round secondhand, working as a window to view more colors as it as it rotates. It turns out, the color changes have to do with polarized light and a phenomenon called bi-refractance. Vectors of light are being rotated as they pass through each material, very different from just color filtering.

The uniquely sculptured case is highly polished aluminum, cut out on a lathe and hand polished the same way they were in the 1970s. Additionally, the strong, metal-geared motor still comes from the same reliable company as it did originally. All paired together with the new LED lamp technology for cooler running, as well as a broader spectrum of more vibrant colors, you get the best in contemporary design --- a worthy continuation of the AURORA.

Other Updates/ Additions:

Brightness Adjustment: There is now a brightness adjustment setting that has been added to clocks made after August 2003. This switch on the LED board allows an adjustment of the brightness to dim the clock in the bedroom or brighten for the office.

The variable spectrum LED lighting source: I thought the clock could be more interesting if it didn't go through the same colors every time the second hand disk was in the same place. I designed a new light source that would have a microprocessor slowly changing the brightness of red, blue, green and white light emitting diodes (LEDs). So red does not dominate yellow, the microprocessor occasionally, slowly, turns off the red LEDs. Similarly, the blue is occasionally turned off so you can see the green colors. A great improvement because the LEDs run much cooler which allows the motor and filters a longer life. Plus the LEDs have a 20+ year life (they do not burn out, but rather just get dimmer). Last, the LEDs produce both more saturated colors and more pastels. This totals up to the best in contemporary design and engineering. Enjoy the Aurora for a lifetime and then pass it down to your descendants.
