Today I’m silver years old, as informed to me by my periodic table.
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.Continue reading
Recently, I had a chance to talk about an approach I developed to help students interact more effectively with on-line instrumentation simulations. I call it [Do][Explore][Act] and it’s an evolution of the Predict-Obseve-Explain approach to doing science demonstrations. The point is to provide mediation remotely so that students have a better understanding of what they are supposed to do with a simulator and how they are being assessed. The presentation has now been posted on DryLabsRealScience youtube channel. You can find the complete playlist here.
I think I will just stay in bed.
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.
