Picture of Delightful Interactive Toddler Spoon

The Concept

Feeding toddlers is a problem for the parents because the toddlers tend to lose their interest easily. Therefore they refuse eating their food and get attracted by other things surrounding them.

Delightful Spoon is an interactive toddler spoon that aims to attract toddlers during the meal time. Thanks to the capacitive touch sensor, every time the toddler puts the spoon into his/her mouth the spoon lights up charmingly.

Step 1: Wiring & Soldering

In order to be sure about the dimensions of the spoon shell, the assembly of the inner parts such as the battery, wires, capacitive sensor and LEDs are needed. Therefore, this step is coming before the CAD process. For the Delightful spoon we will be using momentary stand-alone capacitive touch switch by Adafruit, a 3.7V rechargeable lithium-ion battery and a copper tape to increase the sensitivity so that the sensor switch can sense the magnetic fields of food and the lips to light up the LEDs inside.

Step 2: CAD modeling

We will be using the 3D modelling software Rhinoceros 5 in this step. The 3D modeling steps are as the following: inserting a picture frame that helps us a guideline to draw the curves of the spoon. Then, using the "networksrf" command to create the organic solid shape out of the curves of the spoon. After creating the shell, we will split the whole shape into two pieces as top and bottom pieces so that we can print the shells as hollow and place the circuit inside of it.

Awesome. Do you mind linking to or attaching the CAD file so enterprising modelers can add bits like wings, an animal's face, or other bits that might appeal to specific toddlers?

Thanks! I attached the 3d file upon your comment :)
Woohoo! Airplane wings are a mesh mashup away. Thanks.

thank you, I am developing the project, that is my plan :)
Very clever! It would be fun to see the files you used :D

this is great. I'd also like to see the card, your idea is brilliant.
