Dr. Beddow's instrumentation class has been building the 2016 version of the Cave Pearl datalogger for more than three years, and feedback from that experience motivated a redesign to accommodate a wider range of student projects while keeping within the time constraints of a typical lab schedule. The rugged PVC housing from the older build has been replaced with an inexpensive pre-made box more suitable for "light duty" classroom projects. The tutorial includes a full set of youTube videos to explain the assembly in some detail.

 

Given the technical skill level in the AVRfreaks forum, there's probably nothing new about the logger for forum members. Our real contribution road testing these builds, and in bringing those parts together into a low-cost combination that can be assembled by beginners in a classroom setting. If feel this new design passes muster, then please pass the link on to STEM educators you know who would like to add Arduino-based experiments to their teaching.

A teacher friend asked us for a build that was less dependent on soldering because they didn't have the budget for that kit. So we've developed a "minimum  build" of the 2019 classroom logger using pre-made Dupont jumper cables (as we did in 2016) to reduce the assembly time to about 1 hour.  I've also added support to the code base for using the indicator LED as a light sensor, so they can use the logger with their existing curriculum even if they don't add any extra sensors.

 

 

This version is probably the best starting point for people building their very first Arduino-based data logger.
