Melting lead onto a circuit board using a soldering iron has always been fascinating. I really enjoyed doing it by myself. The second exercise of the day was to build a basic moving object/robot. I built an aircraft with a rotating propeller using a regular motor, 9V battery, wires and a switch. | Melting lead onto a circuit board using a soldering iron has always been fascinating.

DAY 1 Introductory class
Melting lead onto a circuit board using a soldering iron has always been fascinating. I really enjoyed doing it by myself. The second exercise of the day was to build a basic moving object/robot. I built an aircraft with a rotating propeller using a regular motor, 9V battery, wires and a switch.
DAY 2 Trip to S.P. Road

The trip to S.P. Road was quite an arduous one, as I didn't know that ATMs would be so scarce in the area. We walked the entire stretch, from one end to the other at least twice before finally finding one. However, after a chilled coconut juice from a nearby hawker, I felt fresh and satisfied and went on to purchase all the parts that I needed.
Project 1

For the first project, we made a battery using a lemon. The lemon was first pierced with a piece of copper wire and then another piece of galvanized(zinc coated) metal. I used a screw for the latter. The two metals acted as the electrodes(Copper as Anode and zinc as Cathode) and the citric acid as the electrolyte for the conduction of electricity. Voltage measurement using a multimeter showed that the lemon battery had an output of approx. 0.6V. I did this as a part of my 8th grade project so I remembered bits of what had to be done, but doing it again did not diminish it's awesomeness.
