Crayon Prototypes

Several variations of crayons came to being, and two ideas came to our attention as scanned above.
First model failed because we implemented acrylic paint on cardboard. Even though we sprayed acrylic primer and applied gesso on two individual experimentations, and used gloss medium as a finish, the result looked unprofessional and generally unattractive.

We reached a consensus on the Plexiglass tubings so long as costs are low. "Cast tubing" ~$125 is the most expensive material that we know of, followed by "Extruded", and finally "Plastic tubing" being the most cost effective for ~$30.

We require three 1/8" width plastic tubing with 3" Inside Diameter by 24" in height.

We are still rearranging several possible positions for the inside devices. For example finding the material to maximize the protection and usage for LED, placement for "leads" to a on/off switch, a secure way to connect a funnel to a plastic tubing,
using pressure sensitive foam (FSR) as a possible resource for our crayon.
The circled components in image Crayonprototyle2 are of concern for now. We are also planning to put lighting in corresponding color inside the plastic tube to add visual interest to our project.

In terms of exhibition space, we could test drive the finished product at a Daycare center (area and permission conditionally agreed), and even the Telus World of Science (to be determined).

Go team crayons!
