athletes for equal rights - wordpress blog
August 9, 2020I had created a number of websites, but all of those were for myself so I never bothered with content management or a complicated backend. The PHP backend of WordPress was definitely a learning experience for me. After creating a custom theme for the site, I created the skeleton pages that Emma and Olivia would […]
athletes for equal rights - logo and style guide
July 13, 2020The logo and style needed to reflect this spirit. It borrows many of the design cues from the Black Lives Matter movement.Since the logo would appear most frequently on Instagram, creating a small and recognizable logo with a square aspect ratio was important. At the same time, the full name of the AFER is too […]
aquametric - sensor vandalized
June 19, 2020We expected that at some point, someone would want to know about our sensor or want it removed (even though we received permission to mount the sensor), and that is why we provided contact information directly on the device. We did not expect, however, that someone would want to destroy our sensor just for the […]
aquametric - stream cross sectional analysis
May 22, 2020Knowing the depth of the water flowing through a stream is great for knowing when it may flood or how the banks may erode over time, but in order to predict how other bodies will interact with a stream, its often useful know the actual volume of water flowing through it. In order to calculate […]
aquametric - sensor submerged
April 28, 2020Our sensor mysteriously stopped reporting measurements back to us yesterday around 3 am. The battery and cellular strength all seemed to be acceptable, so we were unsure what had happened to it. The last few readings from the sensor show the stream water level rising rapidly, but nothing that we hadn’t seen before in previous […]
aquametric - ota updates
April 24, 2020The frequent trips to the stream for software updates were starting to get tiring, so we sought to implement OTA updates. We also wanted to be able to change the frequency at which our sensor wakes up and takes a measurement (e.g. hourly, every 15 minutes). The Particle Electron microcontroller we are using supports OTA […]
aquametric - quirky sensor data
April 23, 2020Recently, we visited the sensor and did some in-field fixes to the thermistor. The temperature now seems to be sending back sensible readings now and we can see the day night cycle in the stream temperature pretty well. Our conductivity sensor, on the other hand, is behaving pretty strangely. It also shows a daily cycle […]
aquametric - first quality sensor data
April 13, 2020After deploying our latest sensor version to a small local river, we were able to collect some usable stage data during a pretty big rainstorm. Within about an hour of the rainstorm starting, the stage began to climb at a pretty staggering rate. During its rise, we were concerned that our sensor would become submerged […]
