The Course I Wish Existed When I Started

For two years, the most common message I get — YouTube comments, Discord DMs, emails — has been some version of the same question:

"I've been watching your videos for months. I bought a Heltec. I flashed Meshtastic. But I still don't understand how any of this actually fits together. Where do I start?"

I never had a good answer.

Because the honest truth is — when I started, there was no starting point either. I cobbled it together from datasheets, GitHub repos, forum threads, and a lot of failed builds. The knowledge exists. It's just scattered across a hundred different places.

So I built the thing I kept telling people should exist.

Parallel Primer is here.

Why This Didn't Exist

Think about it. Where do you actually go to learn how off-grid, decentralized networking works — as a complete system?

YouTube has tutorials. Reddit has threads. GitHub has repos. But nobody ties it together.

You can find a video on flashing Meshtastic. Another on setting up OpenWRT. Another on LoRa range tests. But understanding how microcontrollers differ from single-board computers, how firmware and Linux and radio layers interact, how LoRa and HaLow and Wi-Fi mesh actually fit together architecturally — that knowledge doesn't live in any single place.

The truth is there's no big corporate interest in teaching people how to build open-source, decentralized, off-grid infrastructure. Nobody's funding that curriculum. The only place you'd probably learn this stuff in a structured way is inside the walls of a defense contractor — and then you can't talk about it. You signed an NDA, you used proprietary gear that costs more than a car, and none of it was ever meant to be in your hands.

What Parallel Primer Actually Is

Primer isn't a tutorial series. It's not a list of projects to follow along with.

It's a structured foundation — that gives you the mental models to design real infrastructure. Not just devices. Infrastructure.

Here's a taste of what's inside:

Hardware Fundamentals — The modern way to work with a Raspberry Pi and microcontrollers like ESP32, Arduino, and Xiao. When to use what, why it matters, and how to stop second-guessing your board selection.

Nodes — All things nodes. Building a Meshtastic solar node from scratch. 3D printing your own enclosures and getting results that actually hold up in the field. Configuring, deploying, and managing the radios that make everything else possible.

Networking Stack — Mesh, MANET, 802.11s, BATMAN-adv Layer 2 routing, and the OpenMANET project. HaLow, LoRa, GPS, satellite, cellular — what each protocol does, where it fits, and when to reach for it.

Reticulum — Building encrypted, identity-based networking over your mesh with RNS. This is where decentralized infrastructure gets real.

OpenWRT & Radio Selection — Flashing, configuring, and understanding OpenWRT. Which radios to use and when — so you're not buying hardware that doesn't match your deployment.

AI Workflows — My favorite AI workflows for accelerating builds, troubleshooting, and working smarter across the stack.

Git & GitHub — Pushing and pulling code with confidence. Spinning up your own repos, contributing to open-source projects, and managing your work like a real developer.

By the end, you stop guessing what hardware to buy. You stop copying other people's builds and hoping they work in your situation. You understand the stack well enough to design your own systems — and your own products.

People have already used what's taught in Primer to spin up their own projects and businesses. When you understand the full stack, you can build things worth selling.

That's the shift — from tinkerer to architect.

Why I Finally Built It

I resisted for a while. Honestly.

I've always believed in open knowledge. The YouTube channel, the blog, the Discord — that's all free, and it always will be. I didn't want to be the guy who gatekeeps the basics behind a paywall.

But here's what I kept seeing: people spending 6, 8, 12 months piecing things together. Buying the wrong hardware because a Reddit thread was outdated. Flashing firmware for a radio protocol that didn't match their use case. Getting frustrated and walking away from the whole thing.

The free content works — if you already know what to look for. But if you're starting from scratch, you don't know what you don't know. And that's exactly where people get stuck.

Primer isn't a paywall on free information. It's structure. It's the map that tells you what to learn, in what order, and why it matters — so you don't waste months chasing dead ends.

I built it because the alternative was watching more people give up on something they were genuinely fired up about. And that bothered me more than the idea of charging for it.

This Stuff Is Valuable

I don't say that lightly.

The infrastructure concepts I teach have been viewed by millions across my platforms. But more importantly — this work has caught the attention of the Department of Defense and some of the most influential military technologists operating in the field today.

I've consulted with senior technical leadership in environments where resilient, decentralized networking isn't a hobby — it's life or death. I've seen what their systems cost. A single tactical radio can run $17,000+. The knowledge behind those systems is locked behind clearances, NDAs, and procurement layers that were never designed to reach you.

Primer doesn't teach you classified tactics. It teaches you the foundational stack that makes all of it possible — using off-the-shelf hardware, open-source software, and publicly available protocols. The same architectural thinking, at a fraction of the cost, with no gatekeepers in between.

That's not a sales pitch. That's the reality of where this space is headed.

The Investment Math

Primer is $249.

Let me put that in context.

The free path: 6–12 months of Reddit threads, half-finished GitHub repos, YouTube rabbit holes, and at least a few wrong hardware purchases along the way. Most people I talk to spend $100–300 on gear they didn't need before they figure out what they actually should have bought. That's before you count the time.

The professional path: Enterprise mesh networking training runs $3,000+ for a 3-day course. Military-grade radio systems cost $17,000+ per unit. That world is built for procurement budgets, not builders.

The Primer path: $249, structured modules, clear mental models, and early wins built in so you're making confident hardware decisions from the jump — not after three months of trial and error.

The real cost of learning this stuff was never the course or the hardware. It's time. Primer compresses the learning curve so you spend your time building, not searching.

Who This Is For

If you've been watching the videos, lurking in the Discord, maybe bought a Heltec or a Raspberry Pi — but still feel like you're missing the big picture — this is your on-ramp.

If you're tired of following tutorials that work in isolation but don't connect to anything larger — this fills the gaps.

If you want to understand off-grid networking well enough to design your own systems, not just clone someone else's — this gives you the foundation to do that.

And if you're already deep in the stack, building Haven nodes and running mesh networks? You probably don't need this. Primer is the foundation. The on-ramp, not the highway.

What's Next

Primer is live now at buildwithparallel.com/products/parallel-primer.

It pairs directly with the Haven Guide — Haven is the build, Primer is the understanding behind it. You can do either independently, but together they cover the full stack from theory to deployment.

If you have questions, the Discord and /r/ModernRadio are the places to ask.

This has been a long time coming. I'm stoked it's finally here.
