OpenRepurposing a Surface HUB 1
I enjoy figuring out how to make locked down hardware useful after its use case is no longer a thing. A few months ago I was gifted a Surface Hub 1.....
Read articleBuilding a WebSite with AI
I am a fan of WordPress but I am also a fan of using the newest tools, my lab for example does run Beta versions just so I can get access to the latest features. So what's a guy to do when I hear that AI can build a website in 10 minutes...

I'm going to go through my thought process for a project I recently completed and that is repurposing a Unifi Cloud Key Plus as a standalone docker host.....
Read articleLearning in IT - Think like an Architect
There are many qualities in a great Engineer and an Architect. I would say that in my experience I have worked with many Engineers that could become Architects if they wanted to. The expectations....
Read articleLocal AI on a Budget
One of my many side projects is using Local AI but like most, I’m on a budget. Smaller models act like smaller models — until you stop treating them as one giant brain.
Read articleThe Modern Engineering Stack: Moving Beyond the Search Bar
AI is quickly becoming an accelerator for more things than just Google searches. Copilot, Claude, OpenAI, and Gemini each earn a different seat in the stack.
Read articleLearning AI – The Basics
Let’s be honest with ourselves, AI is one of the greatest things since the internet. The question is what you offload, and how you stay in control of the result.
Read articleGetting the most out of AI, starts with you!
Prompt engineering is one of the most misunderstood issues with AI for the masses. I asked for a screwdriver, not a therapist.
Read articleBuilding Unifi Analyzer using AI!
I loaded up Visual Studio Code, attached GitHub and Claude, and started building the Unifi tool I had wanted for years.
Read articleAI – Context Engineering Overview
AI is smart and has access to pretty much all data, but it is missing the context you are working in. That is the difference between an answer and the right answer.
Read articlePowerShell in the Field
The public PowerShell repo is the toolkit I am willing to share. Clone it, read it, then run it on a box you can afford to break first.
Read articleMeshtastic NRF MQTT Decoding
NRF Meshtastic nodes will not emit JSON to MQTT. Decrypt the protobuf on a small Python bridge and push a clean topic Home Assistant and Telegraf can actually use.
Read articleMeshtastic TIG Stack
Grafana does not speak MQTT well, and MQTT is a terrible long-term database. Telegraf plus InfluxDB is how Meshtastic JSON becomes a map and a message log.
Read articlePrivate Meshtastic
The public LongFast key is well known. If you do not want strangers reading telemetry off your property mesh, change the primary channel key and own your relays.
Read articleMeshtastic Beginners Guide
Meshtastic is a way to communicate across distances without Wi-Fi or cellular. Range is a mix of height, antenna, and how many friends your mesh actually has.
Read articleNetwork Tool
I asked Warp to combine LLDP Discovery, Port Finder, and Packet Capture into one PowerShell GUI. Six hours later I had a Swiss Army knife I would have spent a week writing by hand.
Read articleLLDP Discovery in Windows
LLDP tells you which switch port a Windows box is sitting on. pktmon already lives on the machine. Wrap it in a GUI and stop tracing cables by guesswork.
Read articlePacket Capture No Wireshark Needed
Microsoft pktmon is a stripped-down NPCAP you already have. Wrap it in a small GUI and you get PCAP plus a TXT file AI can actually read.
Read articleRepurpose Starlink Cable as Ethernet
The new Dishy cable is Ethernet with weird ends and a weirder color code. Here is the pinout that actually passed a 1 Gig wire map.
Read articlePowerShell Introduction
PowerShell is one of my favorite scripting languages. These are the practices that keep scripts readable when you are not the person running them.
Read articleUnifi Security Settings
Zone-based firewall on Unifi was confusing at first. Zones, policies, network objects, region blocking, and honeypots are what I actually turn on.
Read articleUnifi Advanced Networking
Port profiles, DHCP guardian, and a Default network that is not 192.168.1.0/24. The advanced Unifi settings I actually leave on.
Read articleUnifi UDM Quick Start
Unifi is not Cisco with a prettier UI. Get the UDM online, adopt devices, and stand up Wi-Fi without dragging enterprise habits into a 15-minute install.

When people think about using AI it gets daunting. What if you thought about AI as a mentor instead of a technology?
