Circuits and movings parts need a bit of help to get mounted and/or articulated.

Here’s a list of handy diagrams, images on how certain mechanical linkages and contraptions might be constructed. Many of them can be prototyped easily with a laser cutter, and could form the basis for building more robust versions.


Steppers can be confusing initially, due to different number of wires coming out from these things. These links should help to demystify them:

Cable colour codes (typical) for 4-wire steppers:

Seeing weird colours on your stepper? Refer to its datasheet!

What Is The Difference Between 4-Wire, 6-Wire, and 8-Wire Stepper Motors?

How Do I Use a 6-Wire Stepper Motor With My Stepper Motor Drive?

Which wire is which? (covers most types)

Which wire is which? (bipolar steppers, further reading)

Which wire is which? (unipolar steppers, further reading)

How To Decrease Noise on Your Stepper Motor Driver

Modifying the super-cheap 28BYJ48 5V stepper motor into a bipolar stepper (so that it works with an Easydriver or other modern bipolar stepper motor driver board):

General parts / engineering materials / mechanical

When making things, you’ll need materials, general parts, fasteners, and perhaps mechanical components such as gears, shafts, etc:

Microcontroller / Sensors / Components / Electronics kits

These suppliers sell interesting ‘DIY-grade’ components, breakout boards for sensors, sensors, actuators and other relatively affordable parts that are useful in evaluating hardware. Aussie resellers import most of their stock from the folks listed in the World section.
