Starting off from where i ended last week, i began the arduous task of reconstructing my toy after testing the motors. The toy was rebuilt with protruding wires, which will allow me access to the motors from the outside.

After that, i was finally able to start the motor driving handout. The first circuit was a demonstration of using a transistor to control a large current load with the microprocessor.

And shortly after completing that circuit, i was able to start and complete the next circuit in the handout. This circuit was demonstration of a Darlington Pair configuration used to drive a current-heavy load with a high level of resistance on the base of the first transistor.

1/8/13 Building my 5v power supply

The first project of the night was some simple soldering of various resistors and capacitors onto small circuit boards.

After I mastered my circuit board soldering skills, the next task was to solder the ends of numerous, small lengths of wires together in a sort-of ring-like pattern.

When i was able to finish the ring project, i was finally able to move on to the final project of the night, which was my 5-volt power supply that i was to use for the rest of the semester.
