Virtual Technical Meeting: Thursday May 21st

Note the date change! One week later than usual. But it'll still be a Thursday, and still at our usual 6 pm start time. Probably no business portion to start due to virtual format, so presenter content may start closer to the top of the hour than you're used to. Matt Bruzek will tell us about his Texas experiments in robotic lawn mowing, since their lawn mowing season started well ahead of ours.

--

So you are surviving the pandemic apocalypse but your lawn still needs to be mowed. Make a robot mow your lawn instead of you! Matt Bruzek will talk about the robot lawn mowers and give some tips and lessons learned from his adventures in robot lawn mowing.

CANCELLED Social: Monday May 18th

All of Rochester's Litter Bit Better has been pushed to October, so we've been delayed until October 6th, see below.

Litter Bit Better!

Our annual clean up a corner of the world event, helping de-litter a local park as a part of Litter Bit Better. As usual we're teaming up with the geocachers who get CITO credit.

Parking is here or here, in the SE or SW corners of the park. The official group gathering location is on the SE corner of the park.

6 pm start time.

Bags and trash are provided, you need to provide your own gloves and a sense of civic duty. If anyone has some waterproof boots and/or grabbers for cleaning the marshy stream edge, that'd be great too.



Social: April 2020

Instead of a social, practice aggressive social distancing. Take this time to send emails or make phone calls to the people you love.



VIRTUAL Technical Meeting: Thursday April 9th

Kevin's presentation will be about 3D printing. He has two printers and has spent a fair bit of time in CAD modeling various items. He'll cover the basic technologies and show off his gear. This will be live streamed via YouTube at 6:00 Thursday. If you can't join us live, the link will still be available afterwards.

There will NOT be a gathering at RCTC's Heintz Center, please watch from the germ-free comfort of your own home.



CANCELLED - Social: Saturday March 14th

"On Saturday, March 14, there will be an Irish Dance at the Eagles Club in Rochester - 917 15th Avenue SE. Dance instruction begins at 7:00 PM. Dancing begins at 7:30 PM. Tickets at the door are $10 for adults. Children accompanied by an adult will be admitted free of charge. Music and dance instruction will be provided by FriendsOnTheRange. No experience is necessary. All dances are taught. Singles are welcome. The traditional dances of the Irish Dance on March 14 will include both the jigs and reels of the group dances (performed in circles or in long parallel lines) and the waltzes and polkas and hornpipes of the couple dances. Familiar Irish ballads and sing-alongs will round out the evening."

Dancing with kids is fun, bring yours or come share mine.

Technically this event is still happening. But please, practice aggressive social distancing.

You know I'm a biostatistician - these were the two articles that I've generically been waiting for, addressing both the non-numeric and the number-heavy fronts, and I was sent both of them within 20 minutes of eachother on Thursday night. The numeric of these two articles is the first analysis I've seen that's mathematically "felt" right, and you can see how terrifying it is (humans don't mentally do exponentials well, it's well known in the biostatistical community).

Technical Meeting: Thursday January 9th, 2020

Dennis DeLorme, on monitoring current and voltage in his river project.

--

As some of you know I have working with my brother on his river water quality monitor project. He is the director of the Prairie Waters Education and Research Center near Valley City North Dakota (http://www.vcsu.edu/prairiewaters/). One of their programs is River Watch (http://www.vcsu.edu/prairiewaters/river-watch) where high school students monitor a river in their area.

The monitor system is a solar powered data logger recording timestamp, temperature, pH, dissolved oxygen and conductivity.

Last fall I sent out a message asking what parts of the project people were interested in. I got 2 responses one asking how we picked components and one asking about solar power.

To cover these, the presentation will describe the history and evolution of the project over the last couple of years. It will be at a high to medium level. (I already covered specifics of the Bluetooth and WiFi interfaces in previous talks.)

I will also go through some of the problems and data that was collected last fall. Finally I'll demo the current WiFi interface using the actual hardware.
