OpenCTD-JT Parts

thingiverse

The OpenCTD is a budget-friendly, open-source CTD designed for both educators and researchers to use. Built with reasonably accessible parts, this platform runs on an Arduino-based microcontroller. Source codes and building instructions are freely available online. Constructed accurately enough for scientific research, the device can be built for approximately $300 and operates effectively down to 100 meters in depth. To build it from scratch, see: https://github.com/OceanographyforEveryone/OpenCTD These parts are specifically designed for the OpenCTD-JT edition (guide available at https://github.com/Teaguey08/CTeagueD), but based on the https://github.com/CTDizzle/CTDizzle spinoff from OpenCTD, which uses the Arduino MKR-Zero and a Blue Robotics 3" series water-tight enclosure. https://www.bluerobotics.com/product-category/watertight-enclosures/3-series/ The parts include a protector for probe ends, an electronics sled with mounting points for components, a battery holder for a 1s lipo 1000mah, and a sleeve to pot the conductivity probe from the other side, preventing it from being pushed through the epoxy base.
