Your biggest shopping decision for this project is
what to place the project in. The hand puppet idea is nice because it’s
hollow and has a personality, as opposed to using just a plain wooden
box. However, you could technically put the insides of the project into
anything. For example, you could cut open a stuffed toy, take out the
stuffing, and put the project inside. Assuming you take our route and go
with a hand puppet, though, pick out one that you like with enough room
to fit the electronics enclosure and with openings that allow you to
place switches in the hands, face, or other areas. We found one at a
local toy store made by Sunny and Co. Toys, Inc., their item #GL1902.
After you choose your housing unit, shop for the parts for the project
itself, several of which are shown in the upcoming Figures 7-3 and 7-4:
