Graduation Cap LED Hack

Written by: Alan Parekh at 5:48 am. Filed under Electronic Hacks

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.”

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

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

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.

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