Planet Arduino

What’s a hacker going to do with an oven? Reflow solder? Dry out 3D printing filament? If you are [Alicia Gibb] you’d be baking a cake. While complaining that projects aren’t a hack seems to be a favorite past time for Hackaday commentators, we think [Alicia] will be in the clear. Why? Because these cakes have Arduinos, LEDs, and motorized candles among other gizmos.

The Game Boy cake is undeniably cool, although we have to admit the cake that screams when cut got our attention (see video below), even if it would unnerve guests.

As you might expect, you can’t bake the electronics directly into the cake. [Alicia] uses Tupperware or parchment paper to create cavities for the electronics. Connections and other solder joints get professional grade Saran wrap to keep the lead and other awful chemicals out of the cake.

We’ve seen embedded electronics in cakes before, including some that tie into the Star Wars merchandising that seems unavoidable lately. If you aren’t much of a baker, you could always just forego the cake part.

If you like to cook or bake, you probably don’t measure everything out in little bowls and ramekins before you start. Well,unless you also happen to like doing dishes. Even so, there are a lot of measuring spoons and -cups that end up getting dirty in the process. But what if you had a measuring machine to dole out spices and low-viscosity liquids in specific quantities for you?

[enddev]’s creation is based around an Arduino Mega, and the interface is three buttons and an LCD. The user selects between liquid and powder, followed by the desired measurement. If liquid is chosen, the peristaltic pump is engaged to deliver the specified amount through silicone tubing. The current powder setup uses a kitchen scale, which the designers found to be inaccurate for small amounts. They believe that a volume auger and stepper motor would be ideal.

The team mentions that the powder delivery system is better suited for flakier substances since it’s basically agitated out of the container. This makes us think this would be great for feeding fish. If you take this admirably-written Instructable and use it to feed your fish or something, let us know. Their code is on the gits.
