5/19/17 - I missed today for Physics Day, but will make up the time by coming in at FLEX to work on the ROV and helping Mrs. S set up the pool.

5/17/17 - Today I soldered the three small capacitors, the two large capacitors, and the diode. It was difficult to put the large capacitors in the correct orientation.



5/15/17 - Today I finished soldering the fuse holder and power wires and waterproofed it as well. Then I started the Pufferfish circuit board. I soldered in all 7 resistors and the four LED bulbs. It was difficult to solder every connection securely, and I had to double check that the soldering was solid.

5/12/17 - Today I continued to work on soldering the practice circuit board. Soldering in the LED lights was difficult because the holes were very small and close to each other. I soldered both LEDs and one of the motor wires. When we tested the practice circuit board with the 9 volt battery, we could make one LED turn red and green. Next I started soldering the fuse holder and power wires. The wires were so thick that they were hard to solder.

5/10/17 - Today I practiced soldering the circuit board. We soldered all six pegs using two different soldering irons. It was difficult to solder properly because the metal pins did not heat up quickly and the solder was hard to melt. Next class I will continue to work on the practice circuit board.

5/8/17 - Today we assigned roles for making the ROV, and I am working on the control box. I watched videos on soldering and stripping wire, then practiced doing each. It was difficult initially to strip the wire without cutting it, but with a little practice I got the hang of it. Next class I will practice soldering the circuit board.

5/5/17 - Today I took the What is an ROV? Test with Ms. S. We had to know the parts of an ROV, their functions, and the materials. It was hard to memorize. Then we went outside to look at the ROV in the pool. I drove it and got more comfortable with the controls. It was informational to examine a working ROV. We went back inside and researched the different tasks. Next class we will work on each of the tasks.
