N2 TEA Laser Build – Part 4: Circuit & Safety Wiring
Circuit & Safety Wiring. The most critical step now is the wiring. We need to complete the Blumlein circuit and, most importantly, prepare the wiring for the Safety that makes this kit more suitable for classrooms, etc… Triple-Threat Safety Imperative: READ THIS FIRSTTHIS PROJECT INVOLVES THREE DISTINCT LETHAL/HARMFUL HAZARDS. DO NOT ATTEMPT REPLICATION WITHOUT ADVANCED HIGH-VOLTAGE EXPERIENCE AND PROPER VENTILATION.1. Lethal High Voltage: The circuit is lethal. NEVER touch the circuit when power is applied. All components must be contained within a grounded, non-conductive enclosure with safety interlocks before operation.2. Harmful UV Radiation: The laser emits deep ultraviolet () light (around ). This radiation is invisible, damaging to the retina, and can cause skin burns. NEVER look into the beam or at the spark without certified UV-blocking eye protection.3. Toxic Ozone Production: The high-energy discharge generates ozone () gas (a toxic air pollutant). Operation must be limited to short bursts and always performed in a well-ventilated area or under forced exhaust. Classroom Use: Replication in any educational setting requires direct, professional supervision and a fully interlocked safety enclosure system.
N2 TEA Laser Build – Part 3: Capacitor & Switch Math and Fab
In Part 2, I showed you the core components. Now it’s time to prove with math that these components will actually generate a powerful pulse, and then design the two parts that achieve the nanosecond speed: the capacitor’s size and the Spark Gap’s structure, and get the design mostly in place for initial powerup and test.
N2 TEA Laser Build – Part 2: The 10 kV Concept
N2 TEA Laser Build – Part 2: The 10 kV Concept – Okay, I’m ready to pull back the curtain! I’m building a Nitrogen (N2) TEA (Transversely Excited Atmospheric) Laser. This is a high-performance physics experiment that relies on a single principle: speed. We use 10,000V to create an electrical pulse so fast it tricks the nitrogen gas (present in the open air, in this case) into emitting an invisible UV laser beam..

N2 TEA Laser Build – Part 1: What Is That?
[latexpage] The workbench is getting weird this week. (Yes, that’s my Thunder Laser engraver, I know, I know—it’s not supposed to be a workbench! 😅) This is the first in a series of posts where I break down the science and build a ‘Trophy-Worthy’ high-voltage device. I’ve got steel, copper, aluminum, magnets, switches, some wiring, […]
President Dwight D. CB Base Resto-Mod Part 3
🔬 Part 3: Documentation and Cleanup Complete – The Final Blueprint (This post directly follows the investigative findings detailed in President Dwight D. CB Base Resto-Mod Part 2.) This post marks a crucial phase transition! We executed the Initial Restoration (Cleaning) and the rigorous Technical Investigation (Data Collection) using the equivalent schematics. We now have […]
President Dwight D. CB Base Resto-Mod Part 2
🔬 Part 2: Cracking the Case – Board ID, PLL, and Hidden Mods! You can find President Dwight D. CB Base Resto-Mod Part 1 here. The moment of truth arrived! I cracked open the President Dwight D. base station, ready to confirm the board type and uncover the history hidden beneath its metal shell. This […]
President Dwight D. CB Base Resto-Mod Part 1
🎙️ Resurrection of a Classic: President Dwight D. CB Base & Astatic D-104 TUP9 Resto-Mod! Stoked to finally crack open my President Dwight D. CB Base Station! This rig, a decade-long resident of the garage, fired right up a few years ago and was technically working. Now it’s time for a proper restoration and revitalization […]
The Flamethrower
Intro Okay so this isn’t actually laser related (though I could add a red dot pointer to it i suppose!) but it involves high voltage, fire, and more… so the boys and I are going to build a flamethrower. We will go over legalities and use cases as well as best practices of design, build, […]
Overhauling My Old Benchmade AutoStryker
So I’ve been carrying a Benchmade Auto Stryker for decades now, and it was pretty beat up when I got it.. So I decided to use the fiber laser and sandpaper, etc… to clean it all up as much as i can then finish it up on the buffing wheels. I just popped the knife […]
Soltron Electronic PCB VR Replacement
This ia a Soltron Electronic III Display PCB from an Ergoline Soltron Chill XL70 Tanning Bed. This board has obvious thermal defects to the L5973D voltage regulator IC as well as to the trace and the board. It is rumored that this particular board is plagued with this particular issue. The entire board new is […]
