Graduation Cap LED Hack

Long time Hacked Gadgets reader Chris Rybitski sent in this cool Graduation Cap LED Hack. It uses a blue LED to add some electronic goodness to a plain old Grad Cap. By the way, congratulations on graduating Chris!

“I used three button cells from a light up bouncy ball to power the high intensity blue LED. Then I hot glued the batteries to the inside of the cap. To turn on the LED I just put my hand up to the side of my cap and push. Originally I wanted the switch to be in my gown sleeve, but I had no way of hiding the wire going from the cap to the gown. If I had long hair I could have pulled it off. The LED is hardly noticeable until I press the button.”

  1. yup congrats on graduating.
    Although what use is an LED in daylight?


  2. Stuffing a LED in a hat shouldn’t be called a “hack”. What is the purpose?


  3. Grad parties usually go into the evening so I could see it being useful. 🙂


  4. I did this… Only I had about 15 of the ultra bright Led`s. My friend next to me used it as a reading light during the ceremony.


  5. uhh. orginal. but WHAT IS THE POINT?!?!?!


  6. There wasn’t really a point other than to be different. Also the occasional flash at an administrator for kicks.
