After that lecture, I decided to re-record a few choice bits for a more global audience.

My first book, “Beyond Passwords,” is DONE. Wow.
Today marks a big day in my life. I completed my first book. I just sent off the final manuscript for publishing.

To recap: I designed a speaker system from scratch using some small 2″ full-range drivers (for good quality audio), a Raspberry Pi 3 B+, a small 5 watt amplifier, and a wood box I […]
PurpleBlu2 – My First Custom Wi-Fi Pi Speaker Build – PART 1 – Plans
After the success of retrofitting a Raspberry Pi into my old guitar amplifier, I started the design of my next project. This time I didn’t want to reuse old parts. I had the following objectives.

PurpleBlu – My First Pi-Powered Wi-Fi Speaker
It’s been a long time since I last blogged about a technology-related thing I did. I miss that. After talking politics, public policy, and everything else that’s wrong with the world, let’s talk about something cool and exciting – hacking! During my recent trip to Alberta I got to tour some of the maker spaces […]
