Introduction: Motorizing the Doctor Who Pinball Dalek

Picture of Motorizing the Doctor Who Pinball Dalek

Got yourself a classic 1992 Bally Doctor Who pinball? Did you know the first units coming off the assembly line had a moving Dalek robot? The bean counters axed it for cost reasons. But now you can add it back, and it's better than ever! These instructions cover how to install the Ultimate Dr Who Wobble Head Kit by DIYPinball available at from http://wobbleheadkit.com


Step 1: Get the Wobble Head Kit

You will need the Ultimate Dr Who Wobble Head Kit by diypinball(r) available at from http://wobbleheadkit.com

Step 2: Remove Dalek From Pinball Machine

Step 3: Drill Dalek Head

Using an 1/8" drill bit, drill a hole in the Dalek's head

Step 4: Pry Dalek Head Off Body

The head is glued to the body. Pry it off using only your hands. Do not pull the robot's nose. Apply pressure between the bottom lip of the robot head and the body.

Step 5: Insert Motor Bracket

Center the motor's bracket in the neck of the body. Note there are four screws that protrude a bit from the bracket that will help you center the bracket in the body. To ensure the robot head points in the correct direction - 1. Make sure that the large notch is facing forward as shown and 2. Make sure that the bracket is parallel with the flat surface on the back of the robot.

Step 6: Mark Holes

There are four outside holes, mark them for drilling.

Step 7: Drill Holes

Drill the holes you just marked in the previous step

Step 8: Screw Motor Down

There are four large flat head screws that hold the motor assembly into the head. Ensure they are totally flat and remove any extra plastic squeeze-out that may appear - as this may hang up on the rotating head mechanisms.

Step 9: Mount the Control Board

For shipping reasons, the control board isn't attached to the motor. Attach it now using two cap head screws and a 7/64” Hex Wrench.

Step 10: Connect Servo

The wobble head kit from http://wobbleheadkit.com comes with the servo already connected; however, should you accidentally disconnect it, you will want to reconnect it to the three pin connector that marked "servo". You will also want to make sure it's not reversed - so the white wire is connected to the "WHT" pin which is facing toward the big servo motor.

Step 11: Install Head Bracket.

Install the bracket within the Dalek head. Use the two supplied small flat head screws. Make sure the bracket faces the nose of the robot as shown.

Step 12: Install Dalek Head Part 1

Before installing the head to the Dalek, you'll want to put the fender washer under the bracket and the large pan head screw through it. Hold it upside down while installing in to the robot body.

Step 13: Install Dalek Head Part 2

Make sure that the square in the bracket is sitting on the rod correctly, then once the screw is started, you can flip the robot right side up and tighten the screw.

Step 14: Reinstall the Dalek to the Pinball Machine


Step 15: Enjoy!

Excellent idea!!!

I used a similar approach, but then I hooked up the servo to an arduino and wrote a scetch to attach it in the original manner to the solenoid circuit (solenoid25) and the switch matrix of the pinball. The pinball machine thinks now there is a real motorset in the head, just like the original. The signal for the opto is also generated by the arduino, when it is in the center position. Now the head moves also with e.g. the testmenu and "counts" the sweeps... Just like the real thing.

Next I took it one step further and mounted 125 RGB LEDS in the base. They are aranged in 25 columns and 5 rows. I use another arduino with three TM1640 leddrivers to control the 375 LEDS. Animations are stored on an SD card and allow all sort of color animation sequences....

Here is the moving Dalek with an early version, I now have added an LCD and menu to change the settings, speed, way it moves, etc.

Here is it mounted in the pinball:


Here you see work in progress with the 125 animated RGB Leds..
