November 27, 2018
I have now secured a new home for my Dalek … it is now on display at Google’s new office in Boulder, CO! This is a great outcome for me since it will be on display for visitors to see. Thanks to everyone that reached out with suggestions and offers.
Ultrasonic Pi Piano made by students at Georgia Tech
March 18, 2018
It’s great to see that some students at Georgia Tech made their own version of my Ultrasonic Pi Piano design. They documented their build here. I really like the curved design of the enclosure that they came up with to minimize interference between sensors.
Wyzecam Review
March 08, 2018
I’ve recently been experimenting with a couple of Wyzecam cameras and have been recommending them to friends, family, and neighbors ever since and everyone seems really happy with them so I figured I’d try and spread the word further and write up a proper review.
Ultrasonic Pi Piano - Completed Project
July 23, 2017
Several months after creating the Ultrasonic Pi Piano prototype, I have now designed an enclosure for it. The design is very simple but it means that this project is now packaged up and complete.
The Hackaday Effect
May 07, 2017
So this is what happens when your fun hobby project gets featured on Hackaday. I guess I've had my 5 minutes of fame and now I have gone back to obscurity. It's interesting to note that this traffic spike to my YouTube videos only netted me a couple of bucks in revenue so I'm still several years away from receiving my first $100 payout. I'd better not quit the day job just yet!
Making music with Ultrasonic Sensors, MIDI, and a Raspberry Pi
March 29, 2017
I have been working on a fun project to make an exhibit for my local makerspace to take to events. I had a ton of spare ultrasonic sensors lying around so I decided to experiment with turning them into a musical instrument using a Raspberry Pi running a software synth.
Rust is for Robots!
September 23, 2016
Here are the slides from my talk earlier this week at the Denver/Boulder Rust Meetup. I had a ton of fun putting this project together over a four week period and I would encourage others to try their hands at embedded projects with the Raspberry Pi and the Rust programming language. The source code is open source and available here.
Sparkfun AVC 2016
September 18, 2016
We were unable to compete at Sparkfun AVC at all this year due to issues with our compass. Things were working pretty well during practice the day before although the compass was off by about 10 degrees on the run to the first corner. Here's a video from practice which demonstrates obstacle avoidance kicking in when the vehicle was drifting too close to the hay bales.
AVC update 8/29
August 29, 2016
After two pretty intense weekends of learning more about Rust, I now have the new autonomous vehicle basically working. We took it for the very first test run last night and here's the video as captured and instrumented by the Rust code:
