I post many of my projects on public sites for two reasons: (a) they *might* be useful to other people and (b) they *will* get lost if I store them on my home computer. It surprises me when I have a project that has been around for a while and then, seemingly out of the blue, there’s some activity. That is the case with my goiolink package that interfaces Vernier’s Go!Link adapter (and compatible sensors) with Mathematica running on a Raspberry Pi. (Clearly, something that many, many people are doing…)
So I was reasonably surprised that within the span of a few weeks earlier this semester, I received several communications about my code. There is clearly some small interest in reproducing my setup but folks are having problems following the directions. I have little experience in distributing software, and because the Vernier/Mathematica/RPi crowd is a fairly small one, I have access to very few beta testers. If there’s any hope of others using my software, it looks like I’ll need to streamline the installation. So here it goes.
When creating objects for 3D printing, I find I often want to know the volume. In one particular instance, I am making what is called a low pressure drop static mixer and would like to know what volume of a channel is with the mixer installed. Turns out that the problem is easy to solve, so long as you know the right tricks.
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.
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.
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.
