OKCompute Analysis Framework

As part of my work at Swift Navigation I’ve done a lot of work analyzing the results of test runs and building CI frameworks to generate metrics or raise alarms based on the results. One of the challenges is that since the analysis is being performed on devices that are under development, they often create results that violate assumptions made by the analysis code. It can also be hard to trace through the analysis code and come up with the initial failure that led to a missing downstream result.

I made a generic framework to try to help with this sort of analysis.

Wreath Pixel Display

This idea was based on the concept of making a “Sound Catcher” pixel display. I’ve been wanting to make this for a long time, but only recently made the time to put it together. I originally wanted to turn this into a display for ambient sound in the room, but ended up making it into a general audio display and clock.

The video starts off with the display in clock mode, before showing the FFT of a song being chromecast onto a TV. The audio out is sent to the display. I also use a web UI to change displays and set the brightness.

Time Tagger App (Part 1)

I’ve wanted to document my work from start to finish on a project for a while, so I decided to try a screen capture program. I’ve used a bunch of different programs in the past, but I found that I had good luck with one called “Open Broadcaster Software”. It took a little playing with to get the settings reasonable, but I eventually got it working pretty well, and recorded myself setting up the environment and creating a very simple Pebble app:
