MAKE IT.
BUILD YOUR
BUBBLEBOT
Time: A Weekend
Complexity: Moderate
1.SET UP THE FRAME
1a. Start with a sawhorse or
similar frame. Take the 1× 4
shelf, measure about a third
of the way down from the
right side end, and saw a rectangular notch that exactly fits
your servo body lengthwise.
The servo will hold one of the
cord sticks, and we’ll call this
edge of the shelf the front.

1b
NOTE: It probably makes
more sense to buy a sawhorse, unless you enjoy
just about any kind of
woodworking (like me)
— in which case, see
makeprojects.com/v/28
for how I built mine.
TIPS: Drill pilot holes for
the screws to prevent the
wood from cracking.
1b. Attach 2 hinges along the
back edge of the shelf, one
at each end. Similarly attach
the other sides of the hinges
to the top of the sawhorse’s
crossbeam, making sure that
the shelf can swing 90° down
— from flat horizontal to perpendicular to the ground.
1c. Along the front edge of
the shelf, drill 2 pilot holes in
the middle for attaching the
fan, and another hole just
past the fan mounting holes
(opposite the servo notch)
sized for the fixed cord arm.
In the back edge of the shelf,
drill a hole sized for the tilt
lever about 2" from the end
nearer the servo notch.
Mount the fan angled down
somewhat, so that it blows
underneath the arms where
the loop will hang.
