  In order to power the display a separate 12 volt adapter supplying 2 amps was needed. The board and screen does not consume that amount of power but the power supply was already supplied with the screen. To get the touch information to the microcontroller to be interpreted, a four pin flat flex cable connector from TE connectivity was selected.

  Since wind power is typically a clean and efficient source of renewable energy, we analyzed the possibility of using wind power for CSB's electricity needs. This project focused on some of the simple physics behind wind power and the logistics of building one or two turbines on the College of Saint Benedict’s property.

  This drops off at about 30 cycles - 900 motor RPM. The unit will run well at low speeds on 15 to 20-cycle power. I am undecided about the lube system as a solution for low speed operation would be to install an additional small motor to drive the lube pump. Right now, I can easily obtain around 15 RPM on the spindle and retain lube oil supply.

  The first box contained a pre-amplifier composed of an LF 411 op-amp configured as a non-inverting amplifier and powered by an external, adjustable power supply. The second box contained the capacitance circuit described above along with a dual switching device that allowed us to address each tuning fork individually (Figure 6).

  Alternatively, a battery power supply for the SBI is available from Vernier that will make the system, with laptop, independent of AC power. The LabPro interface also solves this problem.) The weight drop experiments can be conducted in a building, but the solid nature of concrete slab floors (if the first floor or basement) makes it difficult ...
