ARH Tech Lab Videos

Technical stories built for viewers, not textbooks.

Explore technical subjects through clear explanations, project context, and build details for viewers who want to understand how the system works and what happens behind the scenes.

Practical Tech. Modern Tools. Proven Workflows.

A lab for makers and engineers.

ARH Tech Lab is where hands-on craftsmanship meets modern technology. The channel follows real projects from the workshop, including CNC machining, electronics, metalworking, woodworking, software, AI tools, video production, and other experiments driven by curiosity and practical problem-solving.

The videos focus on more than the finished result. They explore how things work, why certain approaches succeed or fail, and what can be learned along the way.

AI tools are sometimes used for narration, visuals, and production support, but every project is developed, researched, tested, and reviewed by the creator.

Build, create, experiment, and learn with ARH Tech Lab.

Interactive Companion

Try the Telemetry Troubleshooter

Put the telemetry ideas into practice. Watch a live vehicle sensor trace, spot the anomaly, and classify the fault before the diagnostic window closes.

CNC Build

DIY CNC Router

Walks through a shop-built CNC router, from the welded steel frame and linear-motion hardware to the control chain that turns CAD work and G-code into machine movement.

  • The build uses commercial linear-motion components, ball screws, NEMA 23 stepper motors, and a computer-based control system.
  • The workflow connects Aspire CAD, G-code, Mach3, an Ethernet SmoothStepper, breakout board, stepper drivers, motors, and the mechanical drive system.
  • This machine also supports hands-on projects such as custom embossing patterns for leather work.

AI Workflow

How OpenAI Codex Made This Video

Shows how a video idea becomes a repeatable production workflow, with Codex helping coordinate scripts, visuals, review steps, rendering, metadata, and publishing support.

  • AI can help manage the production process without replacing human review.
  • Good workflows use checkpoints for claims, visuals, timing, and final approval.
  • The same process can support future technical explainers, build logs, and project videos.

Telemetry Series

How NASA Knew Orion Was OK - 250,000 Miles Away

Introduces telemetry through Artemis 2 and Orion: how machines report what is happening inside themselves when people cannot see, reach, or safely visit them.

  • The core chain is sensor, data, transmission, receiver, decision.
  • Telemetry, tracking, and remote control are related but different systems.
  • Telemetry is the nervous system of modern remote machines, from spacecraft to cars to medical devices.

Telemetry Series

Episode 2 - Sensors and Data Acquisition

Zooms into the beginning of the telemetry chain: sensors, signal conditioning, data acquisition, analog-to-digital conversion, and why measurement quality comes first.

  • Telemetry starts before transmission. It starts when the machine measures itself.
  • A perfectly transmitted bad measurement is still a bad measurement.
  • Sample rate, signal conditioning, bandwidth, and trust all become engineering decisions.

Space + Engineering

The Secret Life of Abandoned Satellites

Explains what happens after satellite missions end: burn-up, graveyard orbit, or debris, and why old hardware still matters long after its useful mission is over.

  • Dead satellites can keep moving for years or decades depending on orbit.
  • Orbital debris is a traffic problem, a design problem, and a responsibility problem.
  • The future of space depends on what we launch and what we clean up afterward.
