COVID really made it hard to run the kind of open-ended projects the e360 students normally tackle in Dr. Beddows instrumentation course. So we added a lot of new sensors to the logger build kits we had to send out. Yes, the whole course is being run over Zoom, and no we are not happy about the fact that the students are not doing any soldering... but it is what it is.

As we expected the OLED screens were a big hit, but something that worked even better was the cheap little touch switches we threw in with them.

On their own the switches are twitchy - to the point of being annoying. But once you get enough 'interfering' material in front of them they settle down and fly right. Now if I could only get them to work under water....
