Sand Clock Assembly Manual

Version 1.2 – 23 June 2017

This kit is designed for someone who has intermediate experience with assembling electronics and 

mechanics. 
If you believe that the kit is too complicated for your skill level please do not try to assemble it.
Take your time

 

- it takes approximately 1 ½-2 hours to complete this kit.

Ensure your work area is well lit (daylight preferred) and clean.
Assemble the sand clock in the order as stated in the instructions - read and understand each
step before you perform each operation.
The bags with the mechanical components are numbered from 1 to 5. During assembly you will 
start with bag 1 and end with bag 5.

 

Bag numbers are indicated in the text by use of square 

brackets e.g. [1].

The following tools and materials will be required to assemble the clock:

A good quality soldering iron (25-40W) with a small tip (2-3 mm).

Thin solder wire with no-clean flux. Do not use any flux or grease.

A set of pozidrive screwdrivers or a cordless screwdriver with pozidrive bits.

Long nose pliers.

Tweezers.

A pencil sharpener.

12 mm adhesive tape.

A computer with the Arduino IDE installed.

In this manual, commands are printed in bold e.g. 

svml 1800

.

The position of a servo motor corresponds with the pulse width of the controlling PWM signal and 
is expressed in microseconds (

μ

s).
