About the Dev Kit enclosure

The Bristlemouth Dev Kit comes with a waterproof enclosure that has a 3.5” (150 mm) diameter and is 6” (300 mm) long. The enclosure is based off the one offered by our partners at Blue Robotics.

Adding a new data connection to the end cap

Some payloads or sensors need to be outside of the waterproof housing and need a wet-mate connector. This requires modifications to the existing end cap. There are a number of different strategies, techniques, and off-the-shelf parts that can make this easier.

Before you start, take note of the following:

• Modify the end cap that doesn’t have the Bristlemouth ports.

• Use a drill press or milling machine instead of a handheld drill.

• Multiple bulkhead connectors or penetrators can be added to a single end cap.

• A vent or pressure-relief valve is strongly recommended for the safety and reliability of waterproof enclosures.

• Perform modifications before adding the O-rings, or remove the O-rings during the modification. It’s important to keep the O-rings safe and clean.

• The best location for a penetration is highlighted in red below**.** Don’t drill outside the indent marking the safe area to drill or modify.

  

Add a potted wire penetrator

Adding a potted wire/cable penetrator can be the most cost-effective way to add a new data connection.

Best use: When you’ve got a data cable that already has a wet-mate connector or terminates in a sensor or payload with no wet-mate connector.
