Motorised
Automaton
Head Kit
This exciting kit enables you to construct your
very own motorised automaton head and an
optional wooden enclosure with coin slot.
Instructions are also provided on how it can be
controlled by a Teensy or similar microcontroller.
I have previously made Florence, an animated
automaton head that tells you if it’s ‘Time for
Tea’, Victoria who sings along with a Ukulele
and Matilda who tells fortunes in exchange for
financial renumeration. The incredible interest
they received at steampunk events prompted
me to design the motorised automaton head
kit. (You can name her!)
The kit comes with twenty 3D printed head
parts, the servo motors that allow her to look
up & down and left & right, the DC motor that
opens and closes her eyes, the solenoid that
works her mouth, wires and all the necessary
screws and hardware.
This kit is intended for
more experienced
makers as there are
several mechanisms that
have to be carefully
adjusted and many parts
that require preparation.
You’ll need to decorate
her with spray paint,
apply gloss modeling paint to her lips and use graphite powder as a cosmetic! I’d
also recommend you can solder proficiently.
The kit either comes with a bald head if you wish to purchase your own 9” - 10”
doll’s wig, or with 3D printed Victorian style hair that requires painting in your
choice of colour.
Please note the head kit is not provided with a Teensy or any control electronics as
it is intended for advanced model makers who have the necessary skills to
purchase and manufacture their own control system of choice. I have provided
detailed instructions below on how a suitable control system can be constructed to
allow her to move and speak.
● Constructed from 3D printed PLA+.
● She is 150mm (6”) tall.
● From ear to ear she measures 70mm (2 3/4”).
● Her base has a diameter of 94mm (3 3/4”).
● From her nose to the back of her 3D printed hair measures 125mm (5”).
● Available either with a bald head or 3D printed ‘Victorian’ hair.
● You’ll need a 5volt 1A power supply to set up and test the motors.
● Her eyes are operated by a 3volt DC motor that opens and closes them. A short
pulse of 5volts is sufficient to open and close them.
● Her head is moved by two SG90 servo motors that require a 5volt supply.
● Her mouth solenoid requires 5volts at 0.5Amps.
Assembly Instructions
You’ll require a range of
common workshop tools
along with super glue, some
general purpose adhesive with
which to stick on felt pads,
suitable spray paint for the
base, her skin and hair. I’d
also optionally recommend
using graphite powder and
spray varnish as a cosmetic
and permanent markers and
gloss hobby paint to decorate
her eyes and lips.
In order to set up and test the
servo motors you’ll also require a 5volt 1A power supply and either a servo
motor control module or an Arduino or similar.

watching it all the way through before starting work on the kit - then watching
and pausing each step as you actually follow the instructions. The video’s
comments contain clickable links to each chapter.
Please let me know if you encounter any issues or have any suggestions that
would make the kit easier to construct - john@steamhead.co.uk
1. Assembling the head

Connecting the head to
a microcontroller ((a Teensy)
As this is an advanced kit, these instructions assume you have a basic
understanding of microcontrollers such as the Arduino and the ability to solder.
As before, you’ll also require a 5volt 1A+ power supply.

components can be purchased.

Programming the Teensy
so she can move and Speak
The instruction video below explains how to install the Arduino IDE (Integrated
Development Environment) and how to add the Teensy programming facility.
These will allow you to program your Teensy so your automaton head can move
and speak.
Once you have these installed on your computer, you can click on the zipped
sketch file link to download the sketch (program) I’ve written for the Teensy to
help you on your way. It makes getting her to move and speak really simple to
achieve using a range of ‘action functions’ in the loop() part of the sketch. I’ve
provided comments that will hopefully make the sketch easier to understand.
Please let me know if you encounter any issues or have any suggestions that
would make the Teensy and the Teensy Sound Shield easier to program -

If you require a cabinet in which to mount your automaton head, or want a
cabinet in which to display your own amazing invention, look no further.
The cabinet kit comes with all the laser cut
plywood necessary to build your own
amazing cabinet. It even includes a speaker
housing so you can get your automaton head
talking!
The plywood can easily be stained to suit your
requirements and the instructions explain how
to assemble it with the necessary holes onto
which to mount your automaton head or how
it can be assembled with a plain shelf so you can mount your own invention.
The cabinet’s front panel is the perfect place to
fit any additional controls you require. There’s
even an option to add a coin slot so the automaton head or your own invention
can be triggered into action when a coin is inserted.
