"January" Social: Saturday February 2nd

Sleigh rides! We will go for a sleigh ride at WinterFest for our "January" social. This is an annual favorite with the smaller geekazoids. In fact I think we've even made the advertising photo for this public event, I suspect that mini-Schmidt is in pink on the top of the snowpile and my own blaze orange snowpants can be seen behind the horses to the right of mini-Schmidt.

Saturday, February 2nd, at 10 am.

Park along the road on Salem Road, the sleigh rides are north of the road behind the History Center.

Plan to gather around the Schmidt family. Sorry, no easily identifiable blaze orange to gather around this year.

Technical Meeting: Thursday January 10th, 2019

Dennis DeLorme on his Garagenator (that's garage doing the work of a refrigerator), involving WiFi/Web based temperature sensor/logger:

Did you have the family gathering at your place for Thanksgiving? Did you run out of space in the refrigerator? Did you wonder if the garage temperature was safe for overflow food storage? If so you needed the GARAGERATOR - the WiFi/Web solution to garage temperature monitoring.
In this presentation I'll describe how to use an under $10 WiFi module as a web server to monitor and log temperature. The "user interface" is via a web browser on a laptop, tablet, or cell phone. No special hardware or software is needed on the user side.
I will demonstrate the web server as an Access Point (a stand alone network) to collect and download data. This requires no additional networking, so it is not dependent on a local network.
It can also be connected as a station on a local network and accessible to any device on the local network. I will describe how to do this (it is only a few lines of code difference). I don't know that I will be able to demonstrate this on the RCTC network - as I recall they had some additional interactions to sign on to their open network.
I will cover the hardware and software used in the project. For those that want to get a head start - the hardware is an ESP8266 module, a DS3231 rtc, and a DS18B20 temperature sensor. The software is developed using the Arduino IDE with extensions for the ESP8266 (https://github.com/esp8266/Arduino).
NOTE: This is not an "Internet Of Things" (IOT) presentation. It could be connected directly to the Internet, but I lack the security knowledge (or, alternately, the level of stupidity) required to do that. It can, of course, access the internet via a local network - like other devices on a local network.

KLUG officer nominations and elections (president, vice president, treasurer).

PCIG officer nominations.

6 pm, in or near RCTC Heintz Center's HA108.
