A food + electronics project? Yup. Please be careful if you plan to do this. Electricity and water(melon) don’t mix well. I got shocked a few times.
I made this glowing cow watermelon for my annual Beef Appreciation BBQ. After I gutted the watermelon, I cut out a cow face with a few layers to give it some dimension. I kept it all together and attached it to the watermelon with Kebab sticks and toothpicks.
On the back of the cow face, I cut out a piece of EL Panel that I got from Adafruit. This is cool stuff. I attached it by cutting little tabs that I then stuck into the watermelon rind.
The watermelon not only glowed, but shocked you if you touched it. After being shocked a few times, I decided not to put the fruit salad into the watermelon for the comfort of my guests. However, it did dry before the event and stopped shocking people.
