- Provide students, working on class projects, with components (resistors, capacitors, chips).
- Solder components on boards (chips etc), and test them for correct operation.
- Keep an up-to-date inventory of components in stock and take note of those that need to be replenished.
- Provide other administrative support, as needed

A self-sustainable system that will automatically track the sun’s position and accordingly, change the orientation of its solar panel to get the maximum output from the sun. As one of the rising PV improving solutions, this apparatus implements single-axis solar tracking in an attempt to increase the conversion efficiency of the PV panel. It is a self-powered sustained raspberry-pi based system that can be used as a Solar Energy Supply for low voltage (5V) devices. Two Light Dependent Resistor (LDR) sensors accurately measure light intensity on opposite sides of the solar panel and send this information to the raspberry pi via the analog to digital converter. The raspberry pi then sends pulse width modulated signals to the Motor Driver that sets the motor to tilt the solar panel in the direction of the LDR receiving the highest light intensity.

We built an automatic room light controller for a BEA building on PKFokam's campus. With the objective of reducing the electricity bill, monitoring traffic flow in and out of the building and upgrading the level of technology, we built this system that uses two infrared emitters and two infrared receivers positioned at the door at the entrance of the building to determine if someone entered or left the building. It increments a counter if someone's entering and decrements it when he/she leaves. When the counter is zero, we figured out no lights were needed since this could be very early in the morning or very late in the night, so all lights "in" the building were turned "OFF" automatically and those out of the building were turned "ON". From 8 am to 6 pm the lights out of the building are "OFF" and turned back "ON" from 6:01 pm to 7:59 am. Also, whenever someone enters a toilet or a room, the lights turn "ON" automatically and turn "OFF" as soon as soon as the toilet or the room is empty. All in all, this system cuts off expenses due to lights left in rooms after office hours and ensures at any time we know exactly the number of people in the building.

We built an electric car prototype about the size of a toy car that was powered by a dc rechargeable battery of 12V. It could go forward, backward then stop. Also thanks to the steering mechanism we added to it, it was able to move sideways; all of these, monitored from a wired controller.
