How to Build a Water-Sampling Device for a DIY ROV


At the meetup in Boston over the weekend, we spent a bit of time talking about Jessica's plans for lake sampling and how to go about building a water sampling device.

We've prototyped something before, but never took it much further.

We spent some time thinking about how to build a better actuator for the device. Seems like the Seaperch has been successful with a solenoid valve.

Would love to see your ideas on this!
