NODE by Variable Technologies

Knoxville is on the verge of something fantastic and I’m excited I was able to witness the start of it. I was invited to attend the announcement of the new Variable Technologies office in Knoxville on Wednesday 12/12/12 at 1 PM. 


George Yu, PhD, CEO and Founder of Variable Technologies based out of Chattanooga. 

Alex Lavidge of Variable Technologies and Syner-G explains the NODE to WBIR.

This was also a presentation of their product NODE that was held at the offices of Syner-G. Greg Compton and Alex Lavidge were on hand to represent Variable Technologies and field questions about NODE. Media in attendance consisted of WBIR and the Knox News Sentinel, so I was honored to be in the room given my lack of press credentials.


When I arrived I already had the NODE and the newly released THERMA iOS apps installed on my iPhone 4S because I had been reading quite a bit over the past few months about NODE

George told me to turn on my Bluetooth so I could sync my iPhone 4S to THERMA that was attached to one of the many KORE units on the table before me. I picked up the KORE unit with THERMA and started pointing it around at an assortment of things to take different temperatures in the conference room. I was impressed by the quality of the KORE unit and the durable materials it was constructed out of. The THERMA sensor is held onto the KORE with two tiny screws. The THERMA iOS app was beautiful and well done. It’s quite intuitive and very easy to navigate so anyone thinking about purchasing a KORE and the THERMA sensor don’t be intimidated because it’s easy to figure out.

George said to try the CLIMA sensor next to let me get a feel of the amount of data you’ll have at your fingertips when you purchase the KORE and CLIMA. With the CLIMA sensor I was able to pickup the barometric pressure, ambient light, humidity, and temperature of the conference room. For a weather nerd and National Weather Service certified SKYWARN storm spotter like me this was too much! I was absolutely amazed at the fact that I could so easily pickup everything. George told me about the record feature so I tapped it and let the data flow and eventually I decided to stop it. George said I now had the option to E-mail, Delete, or Cancel. I decided to e-mail the data sets to my Gmail account.

When you tap to stop recording data from the NODE you’re prompted to Email, Delete, or Cancel.


The default file type is .csv that can be read by Excel or Google Sheets and there was one for each data type.

During the presentation I connected to one of the KORE units on the conference table that had the OXA sensor attached to it. I ran through the app and I was fascinated that I had the ability to measure Carbon Monoxide. The poor air quality in Knoxville during the summer justifies the purchase of OXA. The Variable Technologies website states the OXA is an industrial grade Carbon Monoxide sensor. I had a limited amount of time to play around with OXA so I wasn’t able to unlock the full potential of the sensor. 


I went to my iPhone’s Bluetooth display and synced to another KORE unit but this time I was unsure of the sensor I was connected to. I didn’t have this KORE unit in my hand while I was connected because it was one of the many the conference table. I monitored the temperature as it rose and declined  only to spike again as I disconnected from it.

Greg Compton demonstrated how you can use the CHROMA sensor to accurately read and color match multiple paints and have the exact paint code that you or your painter will need to get that last gallon of paint. The broad scope of uses for CHROMA by interior decorators, painters, and contractors are endless. I’m a new home owner and I was thinking of how I could use CHROMA to help with a few remodeling projects I have in mind. I was unable to get a hands on trial with CHROMA but the demo Greg gave us was excellent and showed off the power of CHROMA.

Variable Technologies has a very bright future ahead of it and the NODE has already caught the attention of the tech world. George confirmed that Variable Technologies will take NODE to the Consumer Electronics Show (CES) January 8-11. I can’t wait to see how big of splash NODE will make on the largest stage in the tech world.

January 9, 2007, was the day the technology world was turned upside down. Steve Jobs revealed the iPhone to the public and the cell phone business was never the same afterwards. The original iPhone was released on June 29, 2007 to rave reviews and a huge amount of media attention. Apple was found April 1, 1976 and incorporated on January 3, 1977. Up until January 9, 2007, Apple was known as Apple Computer, Inc., for thirty years. The announcement of the iPhone prompted this change and told the world that Apple was now into more than the Mac computers that carried the company from it’s humble beginnings. The iPhone forever revolutionized the way people and the cell phone companies use, design, and think about their cell phones. The iPhone is way more than a cell phone, it has a camera, an iPod, mobile email client, Safari web browser, and more applications (apps) than you could ever download and actually use in your lifetime.

Apple released the iPhone 3G July 11, 2008, with the choice of 8GB or 16GB capacity. The 16GB iPhone 3G was available in black or white. Apple decided to stop sending software updates to the iPhone 3G. The version of iOS was 4.2.1, that was released November 22, 2010. This essentially made the iPhone 3G obsolete which I’m sure has helped push users to purchase either an iPhone 3GS or iPhone 4. On June 19, 2009, much to the surprise of a lot of iPhone 3G owners, Apple cranked out yet another release that was billed as the iPhone 3GS. The iPhone 3GS was initially available in 16 GB or 32 GB capacity and 8 GB iPhone 3GS came along a little while later.

The iPhone 4 was announced on June 7, 2010, and released on June 24, 2010. The iPhone 4 was a complete re-design of the iPhone 3GS and included the nifty capability of Apple’s FaceTime that was ported over from MacBook. The iPhone 4’s launch stumbled when antenna gate started. Early adopters of the iPhone 4 reported signal strength would drop off when they touched the lower left edge of the iPhone 4. Apple simply issued a statement telling users to “avoid gripping (the phone) in the lower left corner.” After public outcry Apple decided to issue the iPhone 4 plastic bumper that fit around the edge of the iPhone 4 to help with the antenna issue. Speculation of the newest incarnation of the iPhone so far billed the iPhone 5, has reached a fever pitch. Apple plans to make the official announcement for the new iPhone tomorrow at its Cupertino, California headquarters. Many wonder if the newest iPhone will actually be the iPhone 5 or simply the iPhone 4 re-branded with subtle upgrades as the iPhone 4GS. I guess only time will tell what the actual release will be so we’ll all just have to wait and see. Regardless of which version is released it seems that early adopters are already lining up to get their hands on the newest iPhone. just reported the iPhone 5 Expected to “Shatter” Sales Records.
