Date:4.26.18
Location: Logan HS
Time: 3 hours after school
Students: Dom and Andy (Paige and Austin helped on Friday)
Goal: Get the Micro Vibration Motors attached and timer system completed.
The work night tonight was a mixed. We moved forward in some areas and back in others. We wanted to test out the motor delay circuit to help remove water from the radiators. When installing the micro vibration motors, one of the connections snapped off. The wires on the motor are small (I would guess 30 gauge) and difficult to solder so it came as no surprise it happened, it just means we have to solder on another motor.
The delay circuit needed more time to test that anticipated. We had the fundamentals worked out but the voltage output to the 555 timer (in the voltage divider circuit) and the rest of the circuit was to low. Mr. Foye worked with Andy to rewire the circuit as we needed to increase it to 12 v which was done by using some different resistors. Once on the breadboard, the circuit preformed well. Andy will take the circuit and solder it to a circuit board on Friday.
We needed to make another evaporator side peltier module. This was almost completed except for the heat shielding around the wires.
I think we are ready to install the condenser module in the tank now. The prep for that will take place over the weekend.
