Hi everyone,
about 10 years ago I made my own version of the moving Dalek head on Dr. Who. It's a fantastic addition to a great pin.
Why did I make my own version?

1. Fun!
2. Cheaper to make
3. I did not like the movement of the original (no really robotic like)

So the end result is this:

As I said, it's 10 years ago and I don't own a Dr. Who anymore. I found the schematics I made back then and was wondering what to do with them. They are not finished sellable schematics but more like notes.

I would like to help someone make a moving dalek and do so in this thread. I hope someone wants to make one and is serious about it. Perhaps someone can make a nice schematic drawing, make a nice circuitboard out of it or whatever, as long as all is posted here as original.

So, anyone interested? Or anyone have a better idea?

--------------edit----------------

So here is the schematic. I hope we can check this because I do not have a Dr.Who anymore.

How does it work?

Basically we reverse the direction of the motor when it reaches the EOS switch.
It keeps on doing this until the machine stops the motor control.
It will make a full stop because we short the Motor + and -

K1:Motor Control, Apply power to the motor
K2:Reverses polarity to the Motor
K3:Holds Polarity (Set/Reset)

EOS 2 Sets the Set/Reset Relais memory
EOS 1 Resets the Set/Reset Relais memory

Chronologically:

Motorcontrol is set > K1 is activated
Motor starts to turn towards EOS 2 (If it goes to EOS 1 first, switch + and - on motor)
EOS 2 is activated
K2 and K3 are activated
K2 reverses polarity to the motor
Motor reverses direction
K3 keeps power on K2
Center switch is passed, machine knows we are turning heads
EOS 1 gets activated, Power to K3 is lost
K3 deactivates, thus K2 deactivates and polarity is switched
Motor reverses direction again towards EOS2

etc etc

This keeps going until motorcontrol is stopped by the pinball machine.
It will do this the moment it crosses the center switch.

The speed is adjustable by setting the voltage regulator with the pot.

Certainly share the notes. Curious how the body would fit over that mechanism.

Hi, there has been some interest so I'll make some scans of my notes.

The basics of my approach is that I have a motor that turns at the speed I want. Then when head reaches a boundary switch I switch the polarity on the motor making it run the other way. It activates the center switch which is read by the pinball machine. Then it reaches the other boundary switch and I turn polarity again etc etc.

This makes the move so robotic like and for me electronics was a lot easier to make a head turn than making it mechanicaly.

I'll post a schematic.

Thanks MM!

I am looking forward to seeing them!

Rock on!

I would like a chance to build one of these myself.

Please post! It would be a fun project

I'm trying to figure out the circuit board set up for the servos.

I'd like to give a go.

I would build one if I had any skill in that area...

I'm interested. I just mounted a dalek model on the play field and wired it to the dalek topper. I placed 3mm LEDs where the talking lights are and now it lights up as the dalek topper speaks. It's very cool and quite distracting while doing the video mode.

I'll like to give it a shot

Looks like a fun project... Looking forward to seeing your posted notes

How tall is that Dalek? Did it come with lights already? I was thinking about using ships myself to replace those horrible little plastic things that came with the game, but this is cool as well.

There's a guy named Swinks on here working on some nice looking replacements for the ugly switch covers. Check out this thread

It's about 3.5 inches. It's made by Running Press. They have a website and sell these, and other models at Barnes & Noble. I paid about $11 for it. It's head swivels and the lights in the head are translucent plastic held in by a small screw plate, which is easily removed. I drilled the screw plate with holes for the ends of the 3mm LEDs.

After mounting, I wired them up with a 470k resistor (you can use higher resistance for a less bright light). Then I wired that to J127, pin 7, which parallels J128, pin 2. This drives the flasher in the dalek topper, so both light in unison. I also had to lightly file the width of the switch mount on the Cliff hanger so as to friction-mount the dalek over it. It stays on well and can be removed easily.

There are more steps to this mod, however, they'll become obvious to you when you examine the dalek model. If you have a Dremel tool you'll be able to fashion mods easily where cutting and grinding are required.

Has anyone used these schematics to build their own wobble head yet?

#18 4 years ago

This is fantastic! I am interested!

Did the notes/schematics ever get posted? I'm interested as well...

Sorry for not revisiting this thread. I have been out of the pinball world for a while.
I will search for the schematics, redraw them and post them.

first schematic is posted, let me know if there are any questions
