Introducing the world’s first(?) edible and interactive RGB matrix cake — the ArCake.
[Treibair], one of our readers from Germany was inspired a few years ago with the LED cake we made here at Hackaday. Ours used angel food cake squares that allowed LED lights to shine through the squares from underneath the cake, where the LEDs are housed in the technologically advanced cake tray. It worked pretty well but we didn’t exactly recommend people to follow in our foodsteps.
That didn’t stop [Treibair] though, and he came up with his own unique twist on the cake! Instead of bothering with various cubes of angel food cake, he had a much more direct method.
It’s easy to do, just follow these steps:
- Drill some holes in a cake
- Put your jello in that cake
- Make her open the box
And that’s the way you do it.
The resultant LED diffusers let lots of light through, while retaining their most important quality — tastiness. All in all, he made 30 jello filled holes which allowed him to place a 5 x 6 LED matrix underneath the cake. Now when he gives the cake to his wife, it will read her a Happy Birthday message, and then allow her to play a Jump’n’Run game using a Wii nunchuck controller!
