For that authentic pressure washer feel, build the circuit into an old pressure washer nozzle. (You could alternately use an old squirt gun, Nerf blaster, or etc.)
Dissasembly
Unscrew the screws holding the halves of the nozzle together and remove the functional parts.
Fit the Parts
Dry fit the parts to make sure everything will fit before using adhesive foam tape to secure them in place.
The QT Py is mounted in the handle with the USB cable coming out of the base where the water line would normally go.
The 9-DOF sensor is mounted at the base of the barrel, with the Wiichuck adapter and piezo driver and piezo element in the central housing.
Wire Strain Relief
Use a zip tie to connect the Wiichuck cable to the USB cable inside of the handle as shown.
Piezo Element Mount
Remove the protective backing from the small piezo element's adhesive and press it to the inside of the forward handle guard.
Wiichuck Adapter Mount
Connect the Wiichuck cable to the interior of the main housing using double-stick foam tape.
BNO055 Mount
Mount the 9-DOF sensor oriented as shown -- here some foam was used to surround and secure it. You could also use double-stick foam tape instead.
Fasten the Nozzle Halves
Finally, close up the nozzle and screw the halves together -- be sure no wires are in the way before tightening it up.
You're ready to play!
