About me:

I am Hassan Alhaddad, a fresh gradute from Iowa State University, with a bachelor degree in Electrical Engineering. I am looking for an entrly-lavel job in electrical engineering. I am mostly hardware oriented, focused on analog PCB designs, and different sorts of electronics and microcontrollers.

Education:

Bachelor degree in electrical engineering from Iowa State University. Class of Spring 2021.

Experience:

Hardware Engineer

The Wittern Group

CO-OP: Aug 2020 - Jan 2021

Designed a vibration alarm printed circuit board (PCB):
- The alarm operates on a basis of comparators, a vibration sensor, and a PNP transistor.
- Once vibration is detected, the vibration alarm lasts for less than one minute.
- The length of the alarm time period can be controlled by a potentiometer.
- The alarm noise level is 120 dB (very loud).
- The battery life-cycle is 10 years (based on quiescent current consumed).

Designed a motion sensor printed circuit board (PCB):
- The motion sensor operates on a basis of an infrared light receiver,
infrared LED transmitter, and an NPN transistor.
- Once motion is detected, the light last for less than one minute.
- The length of the light time period can be controlled by a potentiometer.
- The motion detection is within a close-range (less than two feet).
• This range of distance detection can be developed as needed.

Worked on testing vending mechanism:
- I ran multiple coin mechanism tests to test the newest MATLAB code.

Worked on harnessing thirty different vending machine boxes
- I assembled thirty vending machine testing-boxes.
• Each box takes a couple of hours.
- Worked on many cable harnessing.
