I finally got a chance to talk publically about a new product I'm working on. Kapsel, a set of SAP plugins for Apache Cordova.

My son and I created an Arduino-powered Pinewood Derby car this year and Make Magazine was kind enough to publish an article about it on their web site. 

I work at home and I spend a lot of time on the phone talking to clients and vendors. My employer uses Google Apps (which includes Google Calendar and Gmail) and the appointment notification capabilities of both are not very robust. Well, they’re robust, but not enough to get me to actually show up for calls on time. What I find is that I often miss the notification when I’m busy doing something else or I notice the notification, but quickly forget about it just a few minutes later and ultimately miss some meetings or join late.

One day, after being 15 minutes late for a meeting, I decided I had to fix this problem. I needed a more effective way to alert myself of upcoming appointments. As I spend a lot of time on the phone, I didn’t want an audible alert, so I decided I’d do something visual. While browsing the Adafruit web site, I noticed the Pimoroni Unicorn HAT and that had me thinking of solution. The Unicorn HAT is an add-on board for the Raspberry Pi that consists of an 8×8 array (that’s 64 total if you’re counting) of bright RGB LEDs. What if I wrote a Raspberry Pi application that connected to Google Calendar and checked my calendar for my next appointment then flashed those 64 LEDs to let me know? As long as I was conscious, and in the room, I’d likely see them and decrease my chances of missing an appointment.

Well, that’s what I did and I’ll show you how to do it too.

AT&T engaged me to write some content for their IoT Starter Kit. It included cleaning up some existing tutorials like this one.

This is my first article published in Make Magazine (available in the December 2016/2017 issue, page 70).

The folks at Make Magazine just launched a new site with hackster.io - community.makezine.com. This link will take you to my project portal where you can see all of the projects I've published here.

The folks at the Raspberry Pi Foundation started a new publication called Hackspace Magazine, and they asked me to pen a series of articles for the publication. This link is to the PDF version of the first issue; my article begins on page 82.

Make Magazine Issue 61, February/March, 2018. I wrote a comprehensive article describing many different ways to work with relays. The Make Magazine team turned this article into a skill builder with more details available online at this link.

For my second article in HackSpace Magazine, I covered how to read digital data in an Arduino Sketch. I showed how to wire up a pushbutton and read its state from a sketch. The article starts on page 79 of the magazine.

For this issue, I continued the theme of reading digital data. In this issue, I covered how to read temperatue and humidity data from a DHT22 device. The article begins on page 82.

It’s easy to get distracted at work and miss the Google Calendar reminders on your desktop and smartphone, especially if you have back-to-back meetings. To help avoid missing meetings, let’s create a Pi Reminder project, a visual notifier that uses the Raspberry Pi and a bunch of LEDs to remind you about upcoming appointments. Being visual-only, it has the advantage of not interrupting important phone calls or chats. The new Pi Zero W and Blinkt! have everything you need in a small, unobtrusive package. An easy project with very little setup.

This is an article I wrote for the Cordova blog that describes how to use the open source Cordova Simulate to exercise your Cordova plugins during development. It also covers how to add support for Cordova simulate to your own plugins.
