Ihave to admit it. I really like the Arduino family of microcontrollers — especially the Arduino Nano. Its mall size and similar functionality to the traditional Arduino Uno make it easy to implement. It does now appear that the Arduino Micro is replacing the Nano. The Micro version supports some additional features and has a slightly larger footprint. The Nano continues to be readily available from many sources and is quite inexpensive, however. It’s very easy to assemble circuits containing the Nano.
I had been working on a 3D printed custom enclosure for the underwater
Quad_ROV recently covered in SERVO (December 2017 and January 2018 issues).
After some difficulties with ABS plastic, I decided to enclose the printer.
Temperature control was necessary, so here’s what I did.
