Splunk LED Meter – RGB LED Strip with Teensy

Splunk LED Meter – RGB LED Strip with Teensy @ Rick’s Awesome Blog.

A few weeks back I had an idea to build an LED meter to display our Splunk license usage at work.  Splunk is an application we use to collect and monitor logs all across our systems.  I currently have a web dashboard that will tell me what our license usage is.  A normal day follows a relatively standard license usage pattern.  It generally rises at a certain rate and hits a certain log volume by the end of the day.  If the log volume is higher or lower than usual, it is a basic signal that something may be wrong on the network.  The problem with the web dashboard is that I have to remember to open that tab and refresh it every so often in order to keep tabs on it.  I figured if I could just have an LED bar on the side of my monitor keeping tabs on the license usage for me, my brain would naturally get used to daily patterns and be able to notice subconsciously when something is wrong.  Last night was our open house night at Eugene Maker Space and I finally had some time to start working on this project.

  1. Thanks for mentioning my project! I’m hoping to have a fully functional version by the end of the week. I’ll be posting more updates as I make progress so check back if you are interested. Thanks again.

  2. Ordering a Teensy to power my RGB LED strips.

    You’re resistor human verification isn’t a color blind friendly method. I used Photoshop to help me pick the correct values.
