Trash to treasure in the chem lab

A few years back, I bought a whole bunch of Fisher brand pipette tips and now my lab is cluttered with a bunch of empty plastic boxes now that the tips have been used and disposed of.  I needed a quick project enclosure to build an instrument for a student and thought this might be an interesting exercise in repurposing.

Using Vernier LabQuest sensors on the Raspberry Pi

In the previous iteration of my website, I had some details about installing the Vernier Go software development kit on the Raspberry Pi and then using Mathematica to visualize the results.  Here is an updated set of instructions which is a little more straightforward.

The chemistry behind the flint water problem

Andy Brunning over at Compound Interest has created a great infographic to help explain some of the chemistry behind the Flint water crisis. The graphic is below, but I strongly encourage you to take a look at his full article

Andy’s post introduces a lot of concepts that could be incorporated into a Chemistry lecture, making it a potentially valuable resource for connecting what students may find as esoteric concepts to real-life situations.  Check out the full article while I jot down some ideas for exam questions….

Packet radio example

I received an Arduino Uno for Christmas this year, so my Dad and I spent some of the holiday time doing some projects.  His job was to get a circuit built implementing a 74HC595 Shift Register and my task was to set up some RF communication.  Dad completed his project before I did, but as I’m on vacation all this week, I was able to finally get something up and running.
