We're proud to announce that we have been boxing and packaging non-stop and, as of today, all of the original awards have been shipped. 

If you haven't received a shipping confirmation email with tracking information, please send an email to so that we can get that information to you as quickly as possible. 

In preparation for your NODE + Chroma's arrival, you will want to download these two apps:

myNODE app for iOS (

Chroma app for iOS ( 

If you had downloaded the Chroma app previously, you will need to update it before using your new Chroma.

Christmas Backers

We are ramping up full-scale production. Currently, we have the Chromas going through an extensive QA process, so you will be receiving the revised version of Chroma soon. Within the next week we will be sending a survey to confirm that your original shipping address is correct.

Enjoy your new Chroma! And don't forget to tell us how you're using it to @variabletech on Twitter!

Almost ready

Hi Everyone,

We have parts coming in from all over the world for Chroma.

Our revised design now include several enhancements. We now have a snap-on cap for Chroma that keeps dust out and contains a white dot for calibration. The entire Chroma is now black (both plastic and aluminum) to reduce internal optical reflections. The new optical fiber based aperture is capturing more light and is no longer affected by surface gloss. Needless to say, the accuracy has improved significantly.

We will start assembling the devices this week but will need a few more weeks for calibration and testing in our temperature controlled chamber. I will post more pictures of as we assemble the devices.

Thank you for your patience and support

NODE Chroma revision

Hi Everyone, 

It has been a while since I have given you an update on Chroma. This is because we have been working hard tweaking the Chroma design to improve accuracy of the color sensing.  

We had to switch out some LEDs, change the optics design, and add a lens cap to prevent damages to the Chroma color sensing optics. The optical changes now allows Chroma to work on glossy surfaces. 

The revised plastic molds are close to completion. We are still on target to ship out the remaining rewards by end of April despite technical set backs. 

In addition to the physical tweaks, we have also been improving the mathematical algorithms behind the Chroma to provide even further improved accuracy. 

All the Christmas backers who received the Chroma prototypes will also receive the revised Chroma module in April as well. 

I will provide pictures as soon as we receive the plastics parts. 

 Thank you all for your patience. -George Yu

Its a Chroma Christmas!

It has been a crazy dash to make and ship out all the Chroma pledge rewards before Christmas but we have done it!

If you already own a NODE, you need to upgrade the NODE firmware before using Chroma. Please go here in our forum for firmware loader for either PC or Mac.

NODE has also been in the news lately.

Business Week

Have a Merry Christmas and Happy New Year from George, Wade, Andrew, Greg, Sheila, and Kris of the Variable Technologies team.
