Microcontroller or microprocessor. I’ve worked with hundreds of product creators, and this is one of the most expensive decisions people get wrong. We’re talking six months of wasted development and tens of thousands of dollars, because the fix usually means … read more
The wrong microcontroller family won’t just slow you down, it can trap you in a dead-end architecture that forces a complete redesign right when you’re ready to scale.
In this video I’m going to rank every major MCU family, from … read more
These 10 components show up in almost every tutorial, dev kit, and prototype out there.
But if you design any of them into a product you plan to manufacture and sell, you could be looking at failed certifications, unreliable products, … read more
ESP32, Arduino, Raspberry Pi.
Picking the wrong one for your product can cost you months of rework, higher certification costs, and a bill of materials that never made sense in the first place.
The internet is full of comparisons between … read more
Choosing the wrong microcontroller can lock you into months of rework, destroy your margins, or leave you completely stranded when the manufacturer moves on.
And after reviewing hundreds of hardware designs, I keep seeing the same 7 MCUs show up … read more
Over the past few weeks I’ve gone deep on AI agents for my own business, and it’s completely changed how I think about marketing.
I built a content distribution system where I can focus all my energy on creating one … read more
There are three stages that virtually every hardware product moves through, from early concept all the way to optimized production.
Most founders either skip one of these stages entirely or get stuck in one way too long, and both mistakes … read more
You’ve heard it a thousand times, hardware is hard.
It’s the unofficial motto of hardware founders.
But that phrase is no longer a warning, it’s your biggest advantage.
It’s hard not to be jealous sometimes.
You’re stuck waiting on prototypes, … read more
Picking a low-power microcontroller that gives you maximum battery life sounds simple.
Just pick the one with the lowest power consumption, right?
Well, there’s a lot more to it.
You have to consider sleep current, active efficiency, minimum voltage, wake-up … read more
Your battery can make or break your product, and I mean that literally.
Choose the wrong one and you’re looking at products that die too soon, catch fire, get held up in customs, or just never make it to market … read more
You’ve spent months developing your product, maybe even years, and you’re finally ready to get it certified so you can sell it.
Then you send it off for compliance testing and it fails, sometimes badly.
Now you’re looking at a … read more
Most people assume hardware products fail because the engineering wasn’t good enough.
But that’s not what kills most hardware products.
What actually sinks them are a handful of business decisions that felt totally reasonable at the time.
Founders make these … read more
When your product needs more than a microcontroller, it’s easy to assume the next logical step is designing a custom board around a faster processor.
On paper it looks simple. Add a processor, add some RAM, and call it … read more
So there’s something you probably don’t really want to think about, but it’s important you hear it.
You can spend months, sometimes years, developing a hardware product and still end up with something that barely sells once it finally … read more
A lot of hardware products fail because one early decision pushed everything else in the wrong direction.
In my experience, the one decision that causes the most consequences is choosing the microcontroller.
Once that part is locked in, everything … read more
People often think the hard part of hardware development is getting a prototype to work. Once the board powers up, the sensors read correctly, and the firmware mostly works, it feels like the finish line is finally in sight.… read more
Most products don’t need the cheapest microcontroller or the most powerful one.
Once you factor in development time, debugging, tooling, and the cost of fixing mistakes later, both extremes can end up costing you more than you think.
What … read more
You’ve spent months, maybe even years, working on your product. You’ve poured in time, money and way more effort than most people will ever realize.
But right when you’re about to launch, everything seems to come to a standstill. … read more
Most people think microcontrollers are simple, cheap, and slow… and microprocessors are complex, expensive, and fast.
In this video I’m flipping that upside down. Because I’m comparing a two-dollar Linux chip against a twenty-dollar microcontroller that’s literally twice as … read more
Thermal issues are one of the biggest killers of electronic products.
Heat degrades components, shortens product lifespan, and can even create dangerous fire situations.
So in this video, I’ll show you 10 common PCB design mistakes that cause thermal … read more
