Todays lessons were quite involved with the electrical components. We started with circuit board construction, soldering components unto the circuit board, SIDs, creating our own underwater ROV camera from the off the shelf back up camera meant for a car, use of epoxy and acrylic to glue and seal components into an acrylic tube, and then unto basics of hydrolics using syringes and test tubes in making an underwater tool to pick up items. We also built our own power cords and attached them to the circuit boxes, soldered the fuse holder to the power cord, and learnt how to use the Anderson Power Pole crimper. A lot of education, at a fast pace of execution but with time built in for hands on practice. I learnt alot today. Quite proud of how the ROV is shaping up!

The South Shore Regional School Board "Brilliant Lab" is located within the Viking Commons at Bridgewater Jr./Sr.
In the spring of 2015, the Nova Scotia Government subscribed to a $400 000 project that would see one makerspace created in each of the provinces school boards.
Day 2 Today we started by reviewing our company name, ROV name and tagline: East Coast Robotics, Gulf Streamer, "Ride the Current". My group partner is a Jane, a wonderfully experienced educator from Florida. Our schedules were redeveloped to include "dependencies" and methods of generating the schedules were shared by each group. We had used Google Calendar...the only group to do so. The remaining topics included - Multimeters: symbols, use of, units- Batteries must be in a case at the side of the pool to provide impact protection. Gel batteries are better than liquid, though an absorbed glass mat battery is best. A marine battery is a good choice as it can be recharged multiple times once emptied. Lead acid batteries do not recharge as well.- Simple Circuits: drawiing circuits, symbols, closed vs open, short circuits, Ohms Law, Series vs Parallel, resistance, LED lights are max of 3 volts and 20 mA, wire gauge, Watts Law, Power.- use of water analogies to electricity. - switches: different types, activity on making your own homemade switch- motors: how they work- Soldering: How to use (ie keep your tip "dirty" with solder...called tinning), waterproofing solder joints with hot glue and shrink wrap.We ended at 5:30 pm.
Day one has come and gone. I've met many new people from the United States. In total, 20 individuals are attending this workshop. 10 men and 10 women. We come from the diversity of cultures and locations but have one thing in common, a strong interest in constructivist education. At the workshop we have had a chance to create our first underwater ROV robot. We have discussed the process of designn and have discussed how to organize and schedule teams of students, how to work with groups of individuals, and some of the tools and process necessary in the creation of these devices. The majority of the afternoon was looking at the design and creation of the frame. It was a lot of fun. Working groups of two we were to design a frame, choose thruster configurations, measure and cut PVC pipe and put together a rough draft of our ROV. My partner Jane is an experienced Chemistry teacher from Florida. Like many I have spoken to, she is looking at teaching ROV robotics as a possible way to extend her career. The high level of interest from students fuels the educator in her.
