We tested our well cap again at higher pressure, and at 53 psi we had no leaks at all. A second cap that is smaller is now in the works. The design for the rear electronics container was finished, taking into account buoyancy, room for SubConn connectors, room for the electronics, and also after calculating the stress and deflection of different components. Our critter collection device is almost done. We tested different ways to collect our water sample. We made a 48 V battery pack to test our robot. We again tested different gauge wires for our tether. We worked more on our website and it is looking better. The electronics was tested over our length of tether and worked well. We took apart our old tethers so we can reuse components.
