Teardown of an Internet of Things (IoT) Wireless Device with Bluetooth Low-Energy and ZigBee

Published on by John Teel

Article Technical Rating: 7 out of 10

The Internet of Things (IoT) is one of the hottest areas of new product development. By 2020 it is estimated there will be 50 billion IoT devices.

Since all of the products I design are protected by NDA, I’ve decided to instead show you the details behind a IoT reference design from Texas Instruments (TI) that offers Bluetooth Low-Energy, ZigBee, and 6LoWPAN wireless protocols.

Hiring an Electrical Engineer to Develop Your New Electronic Hardware Product

Published on by John Teel

Article Technical Rating: 6 out of 10

Developing a new electronic product absolutely requires that you hire the right electrical engineer(s).  As with medicine, electrical engineering is a broad field of study with countless specializations.

Not all engineers are created equal. If you hire the wrong designer your project may take twice as long, cost twice as much, and not even work.

How Much Does a Prototype Cost?

Published on by John Teel

Article Technical Rating: 6 out of 10

One of the first steps on the road to developing and marketing a new product is the creation of a prototype. The cost of a prototype can be broken into two parts: the engineering cost to design it, and the actual cost to produce it.

The total cost of the prototype (assuming an electronic product) usually includes the cost to manufacture the custom Printed Circuit Board (PCB), plus the cost of assembly, plus the cost of the components, plus the cost of the enclosure prototype.

The 5 Steps of Product Development for a New Electronic Hardware Product

Published on by John Teel

Article Technical Rating: 5 out of 10

The new product development process for an electronic product (or any product) is by no means simple. It’s a pretty overwhelming task especially for those with limited resources such as entrepreneurs, makers, start-ups and small companies.

However, the process can be simplified by breaking it down into five steps. The steps summarized below will get you to the point of having a fully functional prototype.

PCB Design – The Top 5 Mistakes Made on Printed Circuit Board Layout

Published on by John Teel

Article Technical Rating: 9 out of 10

There are a few mistakes that I see over and over when it comes to hardware design.

More specifically, I see errors with the design of the Printed Circuit Board (PCB) that connects and holds all of the electronic components together.

Okay, lets now look at 5 of the most common PCB mistakes that I see when reviewing other designs.

PCB Design – Making Your PCB as Small as Possible

Published on by John Teel

Article Technical Rating: 9 out of 10

When it comes to new hardware products many times smaller is better. This is especially true with wearable tech products and Internet of Things (IoT) products.

One of the keys to a smaller hardware product is of course a smaller Printed Circuit Board (PCB).

A technology for reducing PCB size that shouldn’t be overlooked if small size is critical for your product is the use of blind and buried vias. Their use allows the components on a PCB to be packed much tighter.
