Raspberry Pi Standoffs

Use the following hardware to install standoffs to the Raspberry Pi.

  • 4x M2.5 x 12mm FF standoffs
  • 4x M2.5 x 4mm long machine screws

Install Standoffs

Insert machine screws through the four mounting holes on the Raspberry Pi. Fasten the standoffs onto the machine screws.

These standoffs will be used to secure the Raspberry Pi to the stand.

Connect Flex Cable

Insert and install the flex PCB cable on to the camera connector on the Raspberry Pi. Thread the flex PCB cable through the slot on the BrainCraft HAT – Pull the cable all the way through. Then, install the BrainCraft HAT on top of the Raspberry Pi. Firmly press the headers together.

Secure Pi to the Stand

Use 4x M2.5 x 10mm long machine screws to secure the Raspberry Pi to the stand. Place the Raspberry Pi with four standoffs that you installed earlier over the holes on the bottom of the stand. The BrainCraft HAT should be facing towards you. 

Servo Installation

Install the Servo in the large rectangle opening on the front of the stand. The fit is a bit tight, but it can be worked in.

Use 4x M4 x 8mm long machine screws to secure the servo to the stand.

Camera Housing Installation

Using the 1/4" Screw with D-Ring, attach the backside of the housing onto the stand.

Camera Installation

Slip the camera Ribbon cable through the slot under the housing making sure the contacts are facing away from the camera.

Make sure the plastic cable holder is gently pulled out. Insert the ribbon cable into the camera and slide the cable holder back up into place.

Put the camera in the housing and attach the cover.

Attach the Keys

Attach about 2 keys per zip tie, attach the keys evenly spaced around the wheel. You will want to keep the Zip ties kind of loose so they can still jingle, but no so loose that the keys end up flopping behind the wheel.

Place the fine pitched screw that came with the servo into the wheel.

Attach the Wheel

Using the screw in the wheel, attach it to the servo. The weight may make it feel slightly unstable until you attach the feet to the bottom.

Finish up the Wiring

Connect the pins from the JST connector to the servo as follows:

  • Red on the JST connector to Red on the Servo
  • White on the JST connector to Yellow or Orange on the Servo
  • Black on the JST connector to Black or Brown on the Servo

Once connected, tuck the wiring out of the way. Underneath the Pi works very well.

Attach the Rubber Feet

For the Final touch, attach some rubber feet to the underside. Try and place the ones in the front as close to the edge as possible. This helps with the balance of the entire stand.

Congrats! The project is assembled and ready for use.
