Experimentation
We thought it would be good to include solid research experimentation in our exploration of CryoComputing.
Circuit Setup:
 Picture of the whole circuit. The two disconnected wires on the left are to be connected to the 5 volt power source. |
Procedure in Brief:
-
Connect 5 volt power source to circuit.
- Connect oscilloscope to the circuit to see the oscillation of the voltages.
-
Connect electronic thermometer to the circuit to measure the temperature of the circuit operating environment.
Mike, demonstrating how to spray the circuit with freeze spray.
- Spray freeze spray on the circuit to cool it.
- Measure temperature with the thermometer and the frequency of the oscillation with the the oscilloscope
- Continue measuring temperature and frequency as the temperature of the circuit gradually reaches room temperature.
- Repeat, if desired to get more data.
