This caterpillar night light is for children. I modeled it on the shape of a neck roll pillow. It is for when a child wakes up in the middle of the night. It is soft and big enough that it can double as a small pillow and does not take fine motor skills to turn it on. The light is meant to be soft enough to not disturb any other sleepers.
It was an interesting challenge to work with the light as well as the plush negative or light knock-out stripes.
This is the pattern:
In progress images and first circuit. The circuit was modified to include two more LED’s for the antennae:
Here is the circuit diagram:
Building the circuit and diffusing the light was challenging. The ping pong balls helped amplify the light and the tubing helped work the light into the antennae.
The materials for the plush night light include:
- muslin and plush
- ping pong balls
- 2 pipe cleaners
- 6 ping pong balls
- 10 LEDs
- 10 100Ω resistors
- battery pack
- 3 AAA batteries
Here is the first prototype:
Here are the early brainstorming sketches:
