One of my first Raspberry Pi projects was a Pi Palmtop. It was based on a build over at Adafruit and was my entry into building a self-contained device with a 3D printed case. It was fun, and got some decent use. One of the projects I did with it was incorporate Vernier sensors to make a RPi clone of their data acquisition system.
Now, it’s time to say goodbye. I need the keyboard/mouse that is part of the build for my new Pi projector. Now that I’m pulling it apart, I see there’s a bunch of cool stuff in there (speaker with amplifier, still functioning Li-Poly battery, touchscreen) that will undoubtedly be harvested for future projects.
In a week, I return to teaching classes, and my course is going to meet face to face. The pandemic has kept me indoors more or less since the week before Thanksgiving, so I am itching to see students. That said, I’m aware that the virus is not at all contained, and there’s little chance for me to get the vaccine in the near future. [Yes, as a faculty member, I’m allowed to get the vaccine, and I can get it … sometime in April … when classes will be essentially over.
Enough of my soap box. I wanted a way to interact with students during office hours, but was worried if we were trying to show work on a computer screen or piece of paper (and thus breaking social-distancing guidelines). I decided solve this problem as I normally do lately – with the help of a Raspberry Pi.
Enter – the Pi Projector.Continue reading
One of the standing traditions in my household is to get thoroughly immersed in Christmas music during the holiday season. For years, this has involved Pandora streams and Raspberry Pis. This year, I built on that tradition with a little help from some Adafruit gadgets:

I’m working on creating a chatbot for Discord. Why? Well, in part because I want to, but also I’m trying to figure out if bots can be used to improve instructional delivery in Chemistry. I’ve got a way to go, but I’ve only been at it a week. My bot can’t converse very well, but it can integrate, provide weather forecasts and give you the nutritional information of peanut M&Ms. That’s something, I guess.
