We made a powerful ROV. All of parts were tested in our DIY Hyperbaric Test Chamber. The main advantage of our camera is its complete safety. The pressure is created by an ordinary syringe.
For our safety a high-pressure test needs to use water (or another liquid but without air!). In the event of leakage or even complete destruction of a housing or chamber under test, the pressure will instantaneously drop to zero and this will ensure a complete guarantee of our safety. To create a pressure of 100-300 PS you only need a few milliliters of water and in case of a leak you do not even get wet. But how can we create such a pressure without using high-cost compressors? You can do it with one finger using a regular medical syringe! Just draw water into the syringe and push the plunger. The maximum pressure will depend on the strength of your hands and the diameter of the syringe. The thinner the syringe, the more pressure you can create. For example, with a 2 ml syringe I easily create a pressure of 300-360 PSI (200-250 meters underwater!!!)
Moreover, a test with water will allow us to avoid damage to the device under test. You can perform tests even without removing the batteries from the flashlight or the photo camere from the underwater box. Since the test requires only a few milliliters of water, in the case of even the smallest leak, the pressure will drop dramatically and you will immediately see a leak of even a few drops of water!
To make your own Hyperbaric Test Chamber it is enough to choose a solid case of the appropriate size. Now make two holes in the cover and screw the ball valve and the pressure gauge.
