It’s elemental

Posted on by

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.

Do you know what a film canister is?  It’s a small plastic container that used to contain film.  Do you know what film is?  If you don’t, chances are you were born after 2003, which is about the time when digital photography overtook film photography.  It’s interesting that the container that was used to store film has actually outlived the film itself; you can buy packs of film canisters on Amazon for about $0.50 a piece.  They are useful for storage, art projects and film canister rockets.

Orlando ACS

Posted on by

I presented some of my research at the American Chemical Society meeting in Orlando and thought it would be helpful to have a central repository for some of the items I discussed, so here it is.

  • A copy of the powerpoint slides.
  • A link to my Hardwarex paper, which describes the project I discussed.
  • If you missed the big link in the header of my website, I’ve got an entire page devoted to OMIS (which does need updating).
  • The github page which contains the code for programming the Arduino.
  • Want to get started with Arduino microcontrollers (with the intent to build OMIS)? Start with picking up the Arduino and a stepper motor from Adafruit. Then, follow their tutorial on how to use it.
  • The ACS didn’t allow attendees or speakers(!) to access the internet while at the conference (at least the registration fees didn’t go up … oh wait). Ahem, in any case, I wasn’t able to show this video, which demonstrates that two liquids in a 3D printed channel undergo laminar flow.

How can molecules move?

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:

The three general classes of molecular motion.
