Adding fathometer/depth finder to Blue ROV

(Roy Petter Dyrdahl Torgersen) #21

Yeah, we just got v0.3 in last week, but detected a minor problem with the power supply for the RPI3. I believe it has been fixed now, but I’ll double check. If the problem is solved and if we don’t need to redesign the board itself, we should be able to ship a few beta-units in mid september. I’ll check and get back with a price.

That would be fantastic, thank you. I’m still trying to figure out how to connect multiple accessories with the limited penetrators available. I have an extended battery tube with a 7-hole end cap to use as a junction box but the main tube is the problem. If the EnviroSense can send I2C, GPS, and sonar/NMEA over a single cable that will be a great solution.

Yeah, that’s the whole purpose of the EnviroSense. I’ll send you some pictures of our setup tomorrow, but we are basically using a 2" tube as protection for the Atlas sensors, we have a 3" tube (cut short) for the echosounder, and then everything else is inside another 3" tube.

But I’ll send you a picture tomorrow.

Sounds good. I have a 2" tube on the way for the DT800, it looks like it will be a perfect fit with some minor mods. It will be fully enclosed with mineral oil bath and an acrylic end cap at the business end.

Hello Roy, any news?

Any updates on using an Airmar DT800? I’m intrigued about trying to encase it in its own tube with the sensor in water and then a plexiglass end cap. No idea if the sensor would work through the end cap or not. My current project is fairly shallow but the 10’ rating probably would be pretty close. Anybody?
