Wired Birthday Cake

LED electronic birthday cake idea for boysThis birthday cake was a true celebration of all things held dear by my son.  Not being the biggest fan of cake, I decided to decorate it with all of his favorite candies and lay on an extra thick coat of frosting underneath, which his his favorite part. He’s also really into his electronics set and learning all about all things with power, so instead of lighting the cake with candles, we wired it with flashing LED lights all around the perimeter powered by a hidden battery pack.

It took both of us, however to fit the wiring up inside the tubes of licorice that would later run up the sides of the cake and hold the LED lights around the top edge of the cake. The licorice was a key to keeping the wiring elements separate from the edible portions of cake. It also kept it from becoming a fire hazard!

You can see how the wiring was ran up one string of licorice, connected to an LED light, and ran back down the other side. This hid all of the ugly electronics work quite nicely. They only other challenge was concealing the battery pack which powered the whole thing. My solution was to tape it to the cake pedestal and cover it with curly ribbon.

After the wiring basics were in place, it was time to fill in the remaining surfaces with candy. This cake held almost 2 packs of Red Vines licorice, half a bag of Skittles sprinkled on top, 2 packs of Sour Patch ropes, and one large box of Nerds.
