The Steps to a Successful Product

I was stressed out. The startup I was working for just closed its doors. Having a family to take care of, I was on edge. I had a tightness in my chest that didn’t quite go away. The onset of panic came in waves. I was defending myself with a crude stick while my attackers had spears. To take my mind off things, my wife and I decided to get out of the house....

Prototype Electronics With Wire Wrap

Wire wrapping one of my favorite prototyping techniques. Used previously for making the interconnections between integrated circuits on motherboards in the 60’s and 70’s it has since gone by the wayside due to the advent of printed circuit board assembly. I stumbled upon it a few years ago while I was developing some test fixtures for the company I was working for at the time. Turns out that the vendor that was building our fixtures uses it every day!...

Connectivity in an Iot World Long Range Part 2

In my previous article, I went into detail about the short range possibilities for connecting a device to the outside world. But sometimes you need to go the distance; and when I’m talking about distance, i’m talking about 1-12 miles line of sight! In this article, I go into the details about the different types of long-distance embedded communication. These are the types of protocols that get your sensor data to the cloud so they can be consumed by your service and transformed into something useful for the end customer....

Connectivity in an Iot World Short Range Part 1

It’s been a while since i’ve played with Bluetooth and I’ve been researching every connectivity technology that exists to create a IoT. After some laborious searching reading and chatting industry experts, I realized that there were too many to count! In this short series i’m going to deconstruct the biggest players in the arena and tell you the benefits and where they should be used in an end application....

What's Cool in Hardware - May 2017

Over my past few posts there has been a common theme of “using things that already exist.” This stems from a mindset of building things from scratch whether or not they’re actually warranted or needed. For instance, you may work with a fussy firmware engineer who finds the provided vendor code just deplorable to use. That person then takes extra time to go about writing their own platform or system that replaces the vendor code....

How to Wrangle Your Supply Chain

It’s stressful to be on the front lines of a pre-production effort. It’s even more stressful when you are the only person that is responsible for the majority of the design, component selection and procurement. In this post, I’m going to dive in some of the ways you can leverage distribution partners and your factory to manage your bill of materials for you. That way you can stay ahead of the game and focus on what really matters....

Ask the Best Questions at Your Startup Interview

Interviewing at a hardware startup, especially early stage, is a different experience. Founders often have no protocol or rubric for bringing on talent. They will often make a decision by a combination of how they feel about you as a candidate but also your past experience. This is a bit liberating because you don’t necessarily have to be the best technically as long as you can show that you’re providing extreme value....

Hardware Startup Trends

In my 4+ years as someone who has lived and breathed startup, I’ve seen some interesting trends. In this post, I wanted to bring some of these trends to light for people who may feel like dipping their toes. I believe this information will provide a stable starting point for people who eventually want to lead a start-up and bring a product to life. Vision that the leadership believes in...
