Localized IOT – Based on the ESP8266, JSON, and MQTT

My automation project keeps evolving. Here is an image of what one of the sensor/display nodes looks like now. The image is of the IOT Node Base. Contains power regulator. ESP8266 based on the Wemos D1 Mini. A basic sensor node consists of the board above and sensor....

Replace your Raspberry PI with a Dell Wyse 3040 Thin Client

I had a project come up where I was looking for a Raspberry Pi to host it. However, I don't know if you have checked Raspberry Pi pricing or not lately, it seems the "shortages" are effecting them as well. Thus causing the prices to increase for those who have them....

Python Automation – Code Snippet – Return Text File Contents

This Python function will read and text file and return the contents. #usage yourContentHolder = return_text_file_content(path to text file) def return_text_file_content(file): encoding_format = "utf-8" textDataFile = open(file, mode="r",encoding= encoding_format)...

Hydroponics Automation Overview

I have been using hydroponics to grow various herbs, lettuces, and other food plants for some time now. It is a great way to grow fresh veggies. Recently I ventured into designing my own hydroponic systems - as you can see below - this is the test bed I have been...

Python Automation – Code Snippet – Return List of Files in Directory by Extension

This is a Python Code Snippet that will return a list of files based on extension from a directory including full path. #Usage yourlist = return_file_list_by_ext("directory",".ext") def return_file_list_by_ext(directory,ext): import os file_list = [] for file in...

Automation With Powershell and Python – Step 1 Have a Plan

I have been working with computers and other technologies going on 35 years now… I get a kick out of automating stuff. If you want to do more with less - or not have to worry about the boring stuff. Or even if you are not doing the time sucking task - but you want to...

PIC10F322 and XC8 Code – Light Activated Switch

Using the ADC module in the PIC10F322 – we are going to use a photoresistor (see previous post on Using A Photoresistor) and a Potentiometer (another post here about it) – that will turn on and off a LED based on the amount of light. The trigger point is adjustable...

PIC10F322 and XC8 Code – Adjustable Push Button Timer

We are going to take what we have done with the ADC and expand it some more and add in a button and the interrupt base timer code from a previous post. The setup… RA0 – LEDRA1 – PotentiometerRA2 – Push Button (tied to ground) (weakpull-up is enabled) High level… Press...

PIC10F322 and XC8 Code – Using ADC and PWM To Control LED Brightness

In my other post – PIC10F322 XC8 Analog-to-Digital Converter (ADC) Getting Started. I went over the basics of getting up and going with the ADC on the PIC10F322. The code read the value from a potentiometer and if the value was over a certain range – turn on the LED....

PIC10F322 XC8 Analog-to-Digital Converter (ADC) Getting Started

The PIC10F322 Analog-to-Digital Converter has three selectable external analog channels. This allows you to convert an analog signal (voltage) to an 8bit value (0 – 255) that you can use – to do whatever you dream up. Here is the process that enables the ADC on...

The White Rabbit

The Gatekeepers

This is an article a wrote a while back. An article I read got me thinking this morning. It was about Epic Games – VS Apple and Google. In which Epic’s game Fortnite has been removed from both online app stores, basically cutting off Epic from roughly, 3.5 billion...

Movement Toward Localized Computing

Is it just me or have you noticed the move toward a central computing model. With AWS, Azure, Google Cloud, etc.. This has been going on for a few years now. Don't get me wrong, it is an affordable way to have data processing, host your application, what ever you want...
