Using Logical Volume Manager can simplify your disk space management on both large and small Linux systems. This will be both an overview, and a look at specific commands and results. See how LVM can be used to streamline your Linux installation and maintenance.

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

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.

Do you wish there was an easy, cheap way for your micro-controllers to
talk to each other over a wireless link? If so, come and learn about the
Nordic nrf24L01+ type modules. These allow short range wireless
communication in the 2.4 GHz band. The nrf24L01+ is designed for PC
keyboard/mouse, remote controls, home automation, toys etc.
 
There is available software to use the nrf24L01+ modules with common
boards such as Arduino, Raspberry Pi and Beaglebone Black. The nrf24L01+  
module can be added to these boards for about $1 per node, if ordered
directly from China. I'll talk a little about my experience ordering
directly from China.
 
I will talk about the features of the nrf24L01+ and the software to use it. I will demo a sensor star network with a couple of them on Arduinos (what else?) sending data to an Arduino attached to a laptop as the base unit.
 
If you are ready to break your New Years Resolutions, I will be bringing
German Chocolate cup cakes with coconut pecan frosting.

Revision as of 20:00, 7 February 2019



"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.
