Slaton Spangler launches the new "hackable" ATLAS tower light.
Just in time for the holidays, ATLAS Institute is gifting control of its tower lights to anyone and everyone.
Using a smart phone or computer, you too can change things: Make the lights听flash green and red for the holidays, send secret messages in Morse code across campus鈥攖he possibilities are endless.听
鈥淚t鈥檚 pretty fun to see people play with it,鈥� says Slaton Spangler, a longtime lab assistant in the institute鈥檚 Blow Things Up Lab, who built the website and put the hardware in place. 鈥淎 lot of people at ATLAS work on interactive experiences. This is a novel one:听People can control this giant light.鈥�
When Spangler听first approached ATLAS Director Mark Gross with the idea, Gross听was enthusiastic:听"Heck yes, you can hack the tower."
Spangler听devised the system, which uses two credit card-sized microcontrollers to interpret user instructions from the website and听signal听the LED arrays听to change color and flash. From the website, users can define color, duration and transition type. For example,听blue for two seconds might 鈥渟nap鈥� to red for one second, before fading to green for three听seconds. For those so inclined, it鈥檚 possible to bypass the website and just send code directly to the tower microcontrollers. However the code arrives, the system will loop through the latest sequence until someone sends a new one.
The roughly 18-foot tall glass tower, which was included in the 2006 construction of the ATLAS building, was conceived as a landmark in the middle of campus, says Bobby Schnabel, founder and longtime director of the ATLAS Institute.
Previously, there were five pre-programmed color sequences to choose from; changing those patterns required going up to the roof, climbing into the tower and working with outdated software.听
Spangler says this is only phase one, and he looks forward to hearing where future hackers take the project: blinking lights to the beat of a favorite song, broadcasting tomorrow鈥檚 weather using open source data feeds and intuitive color coding are just some of the possibilities.
Everyone is welcome to figure out the next steps.听He's written a . And because the documentation is open source, anyone can replicate and modify the project elsewhere.
Spangler will soon be moving on to support interactive projects at the esteemed Meow Wolf art collective in Santa Fe, New Mexico. First established in 2008 by local artists, Meow Wolf moved into its first permanent facility in March 2016, 听a gift from Game Of Thrones creator George R.R. Martin.
鈥淧eople who hang out in the BTU lab end up doing amazing things,鈥� Spangler says. 鈥淚 learned many of the skills for the tower project from doing my own projects in the BTU Lab, and from helping other students.鈥�
How would he feel if people around the world started playing with the lights?
鈥淚 would love it to get outside the CU Boulder campus,鈥� he says. 听鈥淭he more, the merrier.鈥�
