“I am a Mechanical Engineer by degree, but I have also developed skills in Electrical Engineering and programming from years of projects involving circuitry and microcontrollers. Since employers will expect that I have skills in Mechanical Engineering due to my degree, I decided to make a business card that would showcase my EE and programming skills. I considered a range of options, from a custom-designed PCB with my name and contact info on it and a few useful reference tables, to a PCB with that and a little LED flashlight circuit on it, but ultimately I went with the most elaborate option I was considering, which was a business card with an Arduino and a touch screen on it that would let someone scroll through various information about me. It is admittedly highly elaborate and costly for a business card, but of the possible designs I considered is is easily the coolest and was also the most fun to design and make.
Components:
MicroSD card (optional, I loaded my resume and portfolio onto a MicroSD card inserted into the LCD screen)
