I’m working on a project that will include using LEDs as light sensors, and one of the first tasks is to learn a bit more about the wavelengths of light that are emitted by an array of LEDs. Since I’ve recently created a Mathematica interface to an Ocean Optics spectrometer (on a Raspberry Pi, naturally), the first task was pretty straightforward.Continue reading
I am continuing my exploration of the particle devices. This time, I have a Xenon that is connected to a TMP36 temperature sensor sitting in my office at home. Every second, it updates a variable on the cloud that contains the current temperature of my office.Continue reading
I recently purchased a few particles in part because they are little devices that are named after elements that allow you to connect sensors to the internet; what about these items does not scream BoBtheChemist?
I’m currently running through some tutorials and am sure to forget a thing or three, so I’m going to chronicle my experience in hopes to (a) have a central repository for my work, (b) show that my website does have some activity (c) possibly serve as a resource for the 1-2 bots that frequent my website.Continue reading
My Analytical Chemistry class just started the module on spectroscopy, and I wanted to have a visualization that displayed the different types of motion (rotational, translational and stretching) that molecules can experience. It turned out, I was able to make an interactive (sort of) graphic with a few lines of Mathematica code:Continue reading
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.
