William Dzus Artifacts

Here are my William Dzus artifacts. I admire him greatly. He was a hard-working, kind, and generous man. He came to the United States with little more than ambition and a name of someone to vouch for him and provide him work. He persevered though many setbacks and hardships before gaining recognition though his patent for the Dzus Fastener. He made an important contribution to the WWII defense production, provided his community with jobs, worked to preserve Ukrainian culture, and saved many from the horrors of communism.

He was also my great-grandfather. Thank you, William.

New Compact Prototype

Latest compact board is back from OshPark (www.oshpark.com) and testing is complete. Using the base Adafruit transimpedence amp design we were able to come up with a simple formula for convert the raw ADC values into a UVI. We’re debating whether or not it’s worth it to come up with a resistor divider which gives a bit more signal, but basically doubling the ADC readout and then dividing by 100 does give us plenty of headroom in case someone encounters some really crazy UV exposure. Additionally, we added a slow on-off warning blink should the ADC return a maxed-out value.
