Week+of+11-19-2012

11-19-2012 I went into the lab and found that the parts for the Peltier power supply had finally arrived. First Matt and I went to the Physics stockroom in Nieuwland to get some screws for the various parts to assemble the power box. I then spent the rest of the day soldering wires to their proper joints. This will be the back of the power supply. It includes an input which will be connected to a wall outlet and a switch to turn it on/off.

This power supply will deliver 15 Volts at a current of 6.7 A, slightly over the maximum input amount for the Peltier device but it will still work properly.

This will be the front of the power supply. The BNC connector with the yellow wire will be connected to the output of the rheostat which has an overall possible resistance of 15 Ohms. The input of the rheostat will be connected to the Line from the power supply. The two BNC connectors will be connected on the outside to the Peltier and the blue wire will ground the system back to the ground of the power supply. The variable resistance will allowed for varied changes in the heating and cooling from the Peltier device.

I mainly just spent the day soldering and cutting wires and fixating things inside the box for the power supply. More parts should arrive in the following week that will allow me to begin the building of the scope and I will finish putting together the power supply the next time I go into the lab.
