Serving Middle TN for over 20 yrs.
In a world where we are increasingly tethered to centralized towers, the “off-grid” movement is exploding. If you’ve spent any time in the LoRa (Long Range) radio scene lately, you’ve likely bumped into two heavyweights: Meshtastic and MeshCore. As we previously explored in our Meshtastic 101 guide, these systems are the backbone of modern decentralized communication. […]
This article provides a step-by-step walkthrough for replacing the charging port (DC-In cable) on modern HP 15-inch and 250 G10 series laptops. 🛠️ Preparation & Safety Before beginning, ensure your workspace is a soft, non-marring, and static-safe surface to prevent scratches to the laptop casing or ESD damage to the motherboard. Part Number: N36075-001 / […]
While a high-quality, well-built laser rarely goes out of alignment, understanding the principles behind the beam path is the most critical technical knowledge a laser owner can possess. On a standardized fixed-bed gantry system (like a Thunder Nova, Odin, or Bolt), the goal is to ensure the beam remains parallel to the motion rails across […]
If your car was built in the last 15 years, it likely has an IBS (Intelligent Battery Sensor). This little device changes everything about how you jump, charge, and replace your battery. Mine had one… and I had to go though all of this to figure it out: https://techbravo.net/intermittent-charging-system-anomaly-on-a-2011-kia-sedona-ex 📍 What is an IBS? The […]
This guide details the specific process for reassembling and maintaining a laser chuck rotary, focusing on sequential jaw installation and critical mechanical checks. Proper maintenance and alignment are essential for a chuck rotary, especially since smoke and debris from laser projects can cause mechanical “slop” or jamming.
The “ghost refresh” on Facebook is incredibly frustrating—you find a post, click away for a second to check a fact or grab a link, and when you come back, poof, the feed has refreshed and that post is gone forever. Here is how to solve that Facebook auto-refresh headache using the Always Active extension.
In the world of extreme car audio, the “High Voltage” (HV) approach represents the pinnacle of electrical efficiency. While standard enthusiasts are fighting “voltage sag” with 12V alternators and massive copper cables, HV users are bypassing the bottleneck entirely by moving to systems that look more like an electric vehicle powertrain than a traditional car stereo. A standard car amplifier is a victim of its own architecture. To produce 10,000 Watts from a 12V battery, an amplifier must pull roughly 830 Amps of current ($P = V \times I$). Handling that much current requires multiple runs of expensive 0000-gauge wire and generates massive amounts of heat.
Have you ever wondered why a balloon clings to your sweater, or why a simple walk across a carpet results in a sharp zap when you touch a doorknob? These aren’t just random annoyances; they are measurable phenomena governed by the Triboelectric Series. 🧬 1. What is the Triboelectric Effect? The term “tribo” comes from […]
This is how I use Obsbot Center Hotkeys with OBS Studio and Advanced Scene Switcher to switch between the 3 presets in Obsbot Center without the complexity of using OSC.

🔄 1. Reset the DHCP Lease Pool The most effective way to “kick” all devices and force the router to re-evaluate assignments is to toggle the DHCP server. This clears the active assignment table without deleting your settings. Log in to your dashboard via the ASUS Web GUI. Navigate to Advanced Settings > LAN. Select the DHCP Server tab. Set Enable the […]
If sensors are the “eyes” and switches are the “commands,” actuators are the “muscles.” They take energy (air, electricity, or fluid) and turn it into physical movement—pushing, pulling, lifting, or rotating parts of a machine.
While sensors provide the “automated” input, switches are the manual and mechanical interfaces that allow humans or machine movements to trigger an action. Choosing the right switch is a balance of ergonomics, mechanical durability, and environmental protection.
In an automated facility, sensors act as the “senses” of the machine. Choosing the right sensor depends entirely on what material you are trying to detect and the environment it lives in. This guide covers the most common types of proximity and presence sensors used in the Bravo shop and beyond.

If you operate a laser engraver—whether for profit, production, or passion—you are working with immense, focused power. The difference between a clean cut and a catastrophic eye injury is often measured in nanometers. This guide is your definitive, no-nonsense resource for understanding the one piece of equipment most critical to your long-term health: your eye protection.
Video Intro This is a short video intro about Meshtastic and this guide. Preface This guide represents my journey into the world of Meshtastic. As a novice myself, I’ve struggled to find a single, comprehensive resource that explains the core concepts and provides practical setup instructions. This document is my attempt to bridge that gap, […]
Step-by-Step Guide: Replacing the Alternator on a 2011 Kia Sedona EX A Comprehensive DIY Tutorial for Replacing Your Alternator Introduction This guide provides a detailed, step-by-step breakdown for replacing the alternator in your 2011 Kia Sedona EX. Always consult your vehicle’s service manual for specific instructions and torque specifications and take appropriate safety precautions. Tools […]
This technical case study details the advanced diagnosis of a persistent, intermittent charging system failure and stalling anomaly on a 2011 Kia Sedona EX (3.5L V6). After multiple failed alternator and battery replacements, the focus shifts to finding elusive high-resistance faults in terminations, grounds, and control relays. The guide outlines a precise diagnostic strategy utilizing Thermal Imaging (TI) and specialized electrical testing to pinpoint the true cause of the chronic electrical failure.
Overview There has been much debate, experimentation, and documentation on the subject of water-cooled lasers with regards to the main cooling fluid and additive combinations. The theoretical, as well as practical, implementations and observations, vary from person to person and source to source. There exists a majority, however, of novices and seasoned pioneers in the […]
I did my daughter’s front brakes. Figured I would document my process in case it could help others. Sorry for the audio and background noise, etc… in the video. This was a last minute decision to document the process so I didn’t bother setting up my fancy recording apparatus or practicing, just wanted to get […]
Overview The Bravo Laserworks (BLW) LITA (Linear Integrated Table Assembly) was specifically designed to function with the Thunder Laser Aurora v2 T-Slot bed option factory rotary port but can be adapted for use on just about any galvo laser with a rotary port and typical bed, optical plate, etc… with a LightBurn compatible controller. It […]
