The Wireless Tower of Lights at the University of Idaho is an ongoing project to convert the show's electronics to a fully wireless system. The Tower Lights show is displayed on the south side of the University of Idaho's Theophilus Tower. Each window is rigged with a set of LED lights which illuminate in synchronization to music. The old system relies on the building's unused CAT-5 wiring that runs from the basement up through every room. The new system will not rely on wires, and could be used in any building.

Project Overview[edit]

Background[edit]

The Tower Lights Show has been an exciting part of the University of Idaho for years. The system used to make this light show happen is outdated however. We are renovating the Tower Lights hardware and making it wireless. This new system will be easy to transport and set up, so that the light show could be used in any building. There has been interest for using the system in buildings in Coeur d'Alene, Idaho to put on light shows for events.

Problem Statement[edit]

The​ ​University​ of​ Idaho’s​ ​Tower Lights​ system ​currently​ ​runs​ ​on​ ​old unused​​ Ethernet​ ​wiring​ ​in​ ​the Theophilus​ ​Tower.​ ​Our​ ​team​ ​is​ ​faced with​ ​the​ ​problem​ ​of​ ​turning​ ​the current​ ​Tower​ ​Lights​ ​control​ ​system into​ ​a ​battery​ ​powered​ ​wireless system.

Project Goals[edit]

The current control system must be made wireless. The changes that we will make to the system are outlined below.

Project Problems/Solutions[edit]

Problems encountered during the project, as well as our solutions to these problems, are outlined below.

Problem Solution
We need to identify a wireless protocol to have an effective range of potentially up to 100 meters. Additionally, the frequency must be one that will work even in crowded venues, with lots of different cellphones, and Wi-Fi signals present. The 802.15.4 protocol (Zigbee) is 2.4Ghz, but will not interfere with Wi-Fi. This protocol can operate at a speed of 250kbps, which is much lower than Wi-Fi, but may be adequate for this project. Shown below is a diagram of how 802.15.4 differs from Wi-Fi.
Exact battery selection and design is not yet solidified. Test a couple different battery options once we have completed the rest of the project. Torture/time test each option.
Our wireless protocol can only send 250 kbits/s. If we have enough light bars in a large building, we may run out of bandwidth. We can change the quality of the RGB color sent to each light bar. For example instead of sending 24bit Truecolor RGB with 16 million possible colors, we could send 12bit RGB and have only 4,096 possible colors.

Design[edit]

There are a couple subsystems to our project including the light bar itself, the LED circuitry, and the battery. Outlined below are the diagrams and thoughts that we have put into the project.
