3b. Pop-rivet the battery holders into the body through the holes
in the left side tabs. Rivet from the outside so the ugly side of the
rivet faces the battery.
3c. Solder together the ProtoShield following the manufacturer’s instructions, linked at makezine.com/
19/makey. Use the band saw to slice off the board’s BlueSMiRF header, which connects to Bluetooth
wireless modules. Wasn’t that fun? The header won’t fit in the robot and we don’t use it. Stick the mini
breadboard onto the ProtoShield and plug the ProtoShield onto the Arduino. If you are using a Diecimila,
set its power jumper to EXT.
4. ADD THE SENSOR AND SERVO
4a. This project uses the shorter of the 2-arm horns that come with the HS- 55 servo. Use a 5" bit to drill
out the outermost holes in this horn.
4b. Press-fit the metal pieces of the 2 Du-Bro Mini E/Z
Connectors into the servo horn holes from the front, and secure
them in back with the black rubber pieces. Thread the control
rods from the Du-Bro Aileron System through the connectors
and screw them down using the included screws.
4c. Here’s a tricky part. Plug the servo extension wire into the
Ping sensor board. Bend the control rods from the horn in opposite directions 90°, to reach mounting holes at opposite corners
of the board. The rods will point up from the servo, allowing room
for the extension plug, and the sensor should face out. Slip the
pushrod housing that came in the Du-Bro package over the rods
to avoid short-circuiting the sensor, then secure the rods to the
board using the connectors from the aileron control kit.
4d. Thread the wires from the servo and sensor down through
the rectangular cutout in the body’s top piece. Fit the servo in the
cutout, and fasten using two 1-72×¼" screws and nuts through
the holes on either side. Clip the excess control rod length. Screw
the horn onto the servo and use a small screwdriver to adjust it
so that Makey’s eyes face forward.
