Before mom convinced me there was no future in computers and I should train to be a chemist, I was a dual major in chemistry and computer science. I still do both, along with electronics that I learned in graduate school. Below are some “projects” in both areas.
This is a pickup winder. The motor is salvaged from a battery powered hand-drill. Center section is the speedometer/tachometer/turn counter sensor. A CD with a black tape strip and a opto-electronic reflective sensor. All are hooked up to an Arduino for speed control, turn count, and interaction.
When my wife and I were taking America Sign Language, I developed this pythonista -based app for the iPad to do flashcards. Its general, but since I am not talking ASL right now, it on the shelf in terms of more general usage. The guts are available here.
Most recently I have released ChordCalculus, an iPad tool for the multi-instrumentalist.
