This week, we spent a few hours in the ECE Lab, constructing and finalizing the induction charger circuit. After testing the circuit board for a few weeks, we finally soldered all the wires today and categorized them into a organized form. Along with the finalizing of the circuitry, we were also able to charge two 1.2 volt NiMH batteries that were in a series configuration. The first photo below shows the total voltage of the batteries to be 2.416 volts. After, wiring the batteries directly to the output of the induction charger, 5 minutes of continuous shaking of the magnet-coil system increased the voltage to 2.43 volts as seen in the first photo. The third photo below shows how the charging system was setup.
