Magnetic Levitation!
A couple weeks ago, Vinny and I made and calibrated a circuit during Mechatronics lab that controls an electromagnet to levitate a ball it in the air. Here is a video of it in action:

Every year, CSC (Chinese Students Club) holds a culture show to celebrate Chinese culture. This year’s was last week. I have to say that it was the best Lunar Gala I have seen to date. Transitions between acts were great and each act was very well executed.
The first act was traditional chinese music.
Then it was followed by a dance group.
My favorite act was the Chinese Yo-Yo performance. Vinny and all the guys did a great job. They have a tough job in front of them if they want to top this years performance.
Lion dance was pretty entertaining too. I really liked the glowing eyes.
Of course, there was a fair amount of singers.
Lunar Gala really set the bar high this year. I can’t wait to see how Tamasha, KSA Culture Show, Varsity Show, etc. will be like this year.
Listen closely at 0:49. HAHAHAHAHA. Ironically, the song is titled “Tasty Love.”
This year for Valentine’s Day I decided to get nerdy and make something electronic for Caroline. I first tried to make a animated LED heart with a “joule thief” and a single AA battery, but I couldn’t make a suitable air coil. So, I decided to modify this circuit to make a throbbing LED heart. The circuit uses a 555 timer, NPN transistor, 12 LEDs, a capacitor, and two resistors. The schematic is below. I only drew in 6 LEDs in parallel, but there should be 12.
This is what the finished product looks like:
