Community of Practice: Internet of Things

Hi All,

I’m replacing my old thermostat with a raspberry pi, so I can control the temperature based on Google Calendar events. My intent is to save energy by having the furnace be off most of the day, but still have the house warm when I want it.

You can find the repository at https://github.com/kamocat/Thermostat

I’m using custom hardware actually controlling the furnace and measuring the temperature. I have a 5V relay for the control signal to turn on and off the furnace, and an ATTiny861 to read the voltage off a thermistor voltage-divider. It communicates with the PI over UART.

Hello everyone,

I created an implementation of the Diamond Square Algorithm which is a method for developing procedurally generated terrain that can be used for video games or computer graphics. In this implementation of the algorithm I used java to generate a procedural square terrain with a variable amount of subdivisions. I then exported the vertex information of the terrain as a .obj file which can be used in almost any 3D editor.

Here is a link to the main code for the implementation.

If that does not work here are images of the main functions:

Part 1  Part 2   Part 3  Part 4  Part 5  Part 6  Part 7

Here are some example procedural terrains I generated from the code.

Hey all, there are a couple of useful tutorials related to Windows Kernel drivers and applications. These cover some basics of the drivers and have a similar tutorial to the one I ran, just for Windows 8 rather than 10. The drivers here are pretty simple and give a good overview of the environment.

Hi all,

Here is a basic tutorial on how to setup a web server on the ESP32 with arduino. It’s a great tutorial for an extremely basic webserver to turn on an LED and can be expanded upon to build a web server with more functionality.

Hi all,

If anyone is interested in building an app, a useful way of doing it is by utilizing Xamaring.Forms on Visual Studio. This has an emulator that allows you to see how the app looks on either an Android or Apple device. A link with all this information can be found here. Note that behind the scenes, C# use will be necessary.

Hi All,

This tutorial will give some initiate those who would like to know more about shell scripting.
