We are several weeks into the semester, and my Instrumental Approach to Chemical Analysis students are knee deep in learning about instrument design and preparing their own potentiostats. None of my students had soldered before, and Jarrod gave me permission to share his performance with the world (so long as I mentioned that he’s wearing his Department of ENVIRONMENTAL science shirt to show off his true colors).
And here’s his completed bob173-gamma potentiostat.
Tell Jarrod it looks good. Reminds me of an old test of soldering skills – twelve 1-inch lengths of copper wire, soldered into a cube. Crush the cube by opposite corners. Any joints separate, you fail. I confess – I never passed that.
I suspect I’d fail that test as well. I don’t come across many opportunities to solder three wires together at a single point.
