Use The Particle Squared Air Quality Sensor With Google Docs

Air quality. You probably think about it more now that our clean air has turned into a permanent haze across the sky. Yuck. I’ve previously written about the subject. This post is a straight-to-the-point version which will get you up and running quick! Gather the Goods Get everything together that you’ll need for this project. This includes: A Particle Mesh board (Argon, Boron, Xenon). You can get them almost anywhere....

Homemade Particle Powered Indoor Air Quality Sensor

I got my hands on some of the mesh based Particle boards not too long ago. I’ve been itching to try them out but haven’t quite figured out the project. One thing has been bothering me though: air quality. I spend a good amount of time in my office tinkering, soldering, coding and writing. I sneeze occasionally so I always wondered, how bad is it? The house is also prone to mold exposure during the hot months which had me concerned....

How to Best Power Your Connected Electronic Device in 2018

Use Protocol Buffers to Define Your Service: Part 1

One of the most confusing things about bluetooth low energy is how data is moved around. Depending on your application, your device state may be fairly complex. That means having an individual endpoint for every piece of data is suicide by Bluetooth. So, what’s he solution? Protocol Buffers. A protocol buffer is a programatic way to encode/decode optimized structured data. They can be shared and manipulated across almost any platform....

Dimming AC Lights With a Micro Controller Part 2

No matter how much you research and design a circuit board, sometimes things still go wrong. And nine times out of ten, it’s due to human error. In part two of Dimming AC lights With A Micro-controller, I go into assembling my circuit boards and then testing them. I create a fireworks show on my bench but managed not to burn the house down. If you’re curious how I got here, go check out part one....

Circuit Boards Versus Breadboarding

There’s something that always goes wrong with a first revision circuit board design. No matter how long you spend imagining how a circuit will work, it will bork in the most unexpected ways. In the case of my latest project, I overlooked a critical pice of circuitry. My revelation? Turns out you can’t reliably shunt 375mW of power into a 100mW resistor. 😅 Unfortunately, as you guessed it, this would require rework....

How to Self-Assemble Circuit Boards

Self assembling circuit boards is the cheapest way to get components on circuit boards. Period. Don’t believe me? Believe these screenshots: Self assembled: $143.84 + Tax & Shipping Professionally assembled: $362.83 + Tax & Shipping That’s about $50 per board versus $120 per board. That’s huge. Plus 18 days is a long time to wait for three circuit boards. In this post, I’m going to to talk about the biggest tips and tricks I’ve learned over the years on how to assemble my own circuit boards....

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....

Dimming AC Lights With a Micro-controller

In this post I’m going to talk about how to control AC circuits from a DC powered device. You can go crazy when it comes to this stuff. So my main goal was to keep it simple. Be mesh enabled for future improvements Have the ability to dim the connected lights Have a way to control the dimming functionality The requirements above necessitate a few circuits that need to be mushed together....

How to Best Power Your Connected Electronic Device in 2018

Powering an electronic device is a challenge. Depending on the end user case you may want to use batteries. In some cases, plug it into the wall. Either way there are drawbacks and advantages to either solution. In this article, I dive into the most used methods of powering electronic devices. That way you can make an informed choice and move onto the hairier problems that you’re working on....
