Checkoff 2 was a success! The CVC is almost done and we have two matching photocells now which are working great to sense user hands and light two LEDs. If we have time we'll put two matching LEDs inside the ACV to light when the user has both hands on the mini domes. The second serious water test was as success (we sealed the motor housing this time). The acrylic didn't crack when the bolts were torqued so we should be good to go for the seal. We'll mount the circuits on standoffs just to make sure...
