Submergent Testing the Bolt at 10 Feet

We’ve tested the Bolt to this point with submergent testing to one foot and two-foot feet depth. Today, we are going a little bit further even though the Bolt isn’t really meant to be submersible, and so we want to make sure it’s over-designed and very rugged.

To go further than we’ve done before, we’re in the PMI Aquatic Pool and we have to go scuba diving to test the Bolt at a 10-foot depth. We have a Bolt that’s been charging up, so it’s gonna run on super capacitor while it is at depth. We’re gonna leave this for five minutes and make sure that there’s no water ingress during that five minutes. And then we can look at the humidity with the internal humidity sensor afterwards to make sure there’s no leakage.

The Bolt isn’t intended to be submersible, but we want to over-design the Bolt to make sure it’s rugged and can withstand adverse weather conditions.

Results After Five Minutes at Depth

We’ve taken the Bolt at depth. It was at 10 feet for over five minutes, and now it is back on the surface, we’re connected through USB, and it’s still functioning normally, as we can see. And we’re going to look at the environmental data that we recorded while it was under water.

We were taking temperature, pressure, and humidity readings every 10 seconds, and we started off at about 37% relative humidity and about 978 millibars. After over five minutes at 10 feet, we ended up at 43% relative humidity and 996 millibars. That’s about a 20-millibar increase in pressure, just about seven or eight percent relative humidity. So, the Bolt maintained integrity at 10 feet for over five minutes.
