Wiring Schematic for Bad Boy ZTE Mower
I drew up a partial set (relay functions) of wiring schematics for a 2014 Bad Boy ZT Elite zero-turn mower. These hand-sketched drawings are based on the wiring diagram provided in the user manual. If you are like me, you need to see a schematic to understand the functionality and the diagram they provided is of limited use. Hopefully, these will help someone else out in the future!

Barcode Format Converter
I’ve been working with systems that use 10-digit barcodes. Different systems require that the data be stored in different ways, and I usually can’t decode the values in my head, so I wound up creating a spreadsheet to do the conversion.
I thought this would be a good practice project to teach myself how to use javascript in a webpage. The biggest take-a-ways I learned are:

Private RoIP (Radio over IP) System
Private RoIP (Radio over IP) System
I often work in places that are spread out over large distances and are underground or filled with radio obstructions like thick concrete/steel walls and lots of metal equipment. Getting radios to work takes some infrastructure and money.
Something I usually have access to at these sites: a reliable, isolated, fast network that goes wherever the equipment is at. So I wondered if anyone connected…

MQQT using Node-RED
When I started searching for how to transfer data between 2 computers using MQQT, I saw articles talking about Node-RED, but I dismissed it as being some sort of toy for children. That was probably a mistake because once I installed it, I realized it was both genius and a powerful tool. It lets you do amazing, complicated things without having to get into the weeds in every little detail.

Raspberry Pi Data to Google Sheets
Raspberry Pi Data to Google Sheets
A Raspberry Pi 3B is configured to bring in sensor data through a ADC (analog to digital converter) connected to the pi’s I2C (Inter-Integrated Circuit) serial interface. (I’m using the ADS7830 module that came with a kit that contained all kinds of fun project goodies). I have 2 potentiometers wired to the ADC that I can turn by hand to give me 2 real voltage values. The pi has internet access…

Ignition User Pop Up Data Entry Box
Ignition User Pop Up Data Entry Box
If you want a data-entry pop-up in Inductive Automation’s Ignition, you just call the function to open an input box. This seems simple to computer programmers, but it is different than how typical industrial automation systems. Ignition marries the two worlds, which is one of the things that makes it awesome.
the blue button at the top of the screen has a script that executes when pressed

My Political Opinions Lean...
My Political Opinions Lean…
My political opinions lean more and more to Anarchy… The most improper job of any man, even saints, is bossing other men. Not one in a million is fit for it, and least of all those who seek the opportunity. -JRR Tolkien

Getting Ambient Weather Data into Ignition
Getting Ambient Weather Data into Ignition
I wanted to learn how API’s work, so I figured bringing in some of my weather station data to an Inductive Automation’s Ignition project would be a good task to learn on. I wasted a lot of time trying to use the python helper functions that were recommended in the docs at https://ambientweather.docs.apiary.io/. The problem with that route was that Ignition uses it’s own instance of python…

How-To Get Clean Dishes with a Modern Dishwasher
How-To Get Clean Dishes with a Modern Dishwasher
If your modern high-efficiency* dishwasher is anything like mine, then it is a source of constant frustration. Even pre-washing the dishes doesn’t get them to come out very clean. I think I solved the problem, here is what we do:
wash out the filter every time a load is run
run it with soap for a normal cycle, which takes several hours (can cancel it during the dry cycle if caught in time)…

Canonball Speed Sensors

A customer wanted to use industrial photo eye sensors with a piece of lab equipment to measure the speed of a projectile shot out of a air cannon. I assembled a small box with the parts needed to power it and adjust the voltage levels.
