As you know, Rozenn has done a most excellent job at adding some fiber-art-droid-designs to my office decorations. She also likes to make sure they are appropriately dressed for the season. This year, BB-8 and BB-9E are ready for Trick-or-Treat with custom costumes (and matching candy bags). Remember, if you let your droid go trick or treating, make sure they only get capacitors and ICs for treats; they are allergic to chocolate.
Rozenn had bought some awesome periodic table fabric (which I got for my birthday a few months back) and she finally had the time to complete a pair of periodic-table pillows for my office. They are awesome.
There’s still plenty more fabric, so I suspect there will be another set for my home office as well.
I recently purchased the AMG8833 thermal camera breakout from Adafruit. It’s an 8×8 pixel array of sensors that can be used to incorporate thermal vision into a project. I’m interested in monitoring a thermoelectric cooler. Adafruit provides a number of examples on how to interface the breakout with a Raspberry Pi or display connected to an Arduino. I wanted to try a different interface and see if I could control it with Mathematica. It took me longer to write this post than it did to write the software.

Now that my students are wrapping up their summer research activities, it’s time to share some of my new designs. This one is inspired by my students – they wanted to design and 3D print keychains – and Rozenn’s request to have name tags for our plants.
Read on to see how I designed these, which involved a little bit of magic for the swash ornament.
Our hummingbird feeder was inundated with ants. While there are plenty of commercial options available for solving this problem, I wanted to try my hand at designing my own solution. In thinking about how a water trap should be designed, I came up with the following critical elements.
- A leak-free cup for the water (duh)
- An upper attachment point that prevents tipping of the cup
- A lower attachment point that is integrated into the monolithic design.
Here’s the result.
