What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

Introducing the Axi Clock

The Axi Clock is the first 2 tier axial clock driven by a single gear train and small yet powerful hybrid stepper motor.  It is ready for you to 3D print or CNC machine using various materials such as plastic, wood or even metal.

My Story

A clocks movement has always caught my eye, there complex design have always fascinated to me.  With a background in electronics and 3D modelling I decided to give myself the task of designing a mechanical clock with an horizontal display versus its typical vertical display and with the use of electronics such as ucontrollers, crystal clock timing and a silent stepper motor driver.  With the final working Axi Clock being to costly to produce I've decided to take the consumer DIY approach for everyone to enjoy building themselves.

The Movement

When I started designing the Axi Clock I had the idea of designing my own motor to rotate both the hour and minute axis separately.  Although I don't believe trying to re-invent the wheel is a bad approach, I quickly came to the realisation that using an existing hybrid stepper motor along with a single gear train was the ideal way.  Check it out!

 The PCB

With all the components being through hole for ease of assembly accept for the USB-B micro connector.  The board consists of four essential integrated circuits, the LM7805 power supply, PIC18F13K50 ucontroller, CD4060 counter/divider and the TMC2100 silent step driver.  

With the CD4060 generating a 2Hz pulse from a 32.768kHz crystal, the PIC ucontroller counts 120 pulses and then sends out a pre-determined number of pulses to the TMC2100 driver to increment the stepper motor.  Its that simple.

The Structure

-All structural components have walls no smaller then 2.5mm which is tolerable for plastic, wood and metal.  

-The structure is held together with M2 socket head cap screws.  All of the M2 threaded holes in the 3D files are set smaller for you to tap your self.  

-All gears require MR72 bearings to be inserted and both the minute and hour axis require an open 6816 ball bearing.



Risks and challenges

Once the Kickstarter campaign becomes successful, I will provide a set of instructions on how to program and assemble the clock by January 31, 2018.
The risks and challenges would be not to rush through the assembly of the clock but to take your time for best results.
