It’s only been about a week since our last update, but we wanted to take a chance to collect our thoughts and make sure we kept you all informed in an honest way. With that in mind, let’s jump in!
First things first - what have we been up to behind the scenes. The short answer? Making sure the drones we ship to you are the best they can possibly be. We’ve continued to punish the prototypes we have in house, making sure they meet Fathom’s rigorous quality standards. As we found, this testing has been very beneficial.
In the weeks after we sent out an update in April, we began to notice some finicky behavior with some of the older prototypes. Come to find out, the layout of internal componentry coupled with the Fathom One potting material was leading to heat build up that - over time - was leading to decreased CPU efficiency and battery degradation. Needless to say, this wasn’t acceptable to our team, so we set out to find a solution.
After extensive testing, we found the issue stemmed from the CPU and battery being too closely surrounded with potting material, not allowing heat from the CPU to escape to the front air pocket where it could more easily diffuse into the surround water.
To remedy this issue, we’ve done two important things: the first was to engineer ventilation channels around the drone’s CPU, allowing it the proper “breathing room” to reach an equilibrium at a comfortable 50 degrees Celsius, which is well within its recommended operational limits. The second was to move the battery into the forward air compartment, keeping it at 25 - 30 degrees Celsius to optimize cycle limits and dive times. After we made these changes, our drones have been running smoother than ever.
Until next time,
