Solar clock Kit
C-9738
Check all parts before beginning assembly
The sundial is an electronic kit, which uses photovoltaics as an energy source.
Photovoltaics, is stored in a battery that powers the clock mechanism.
In the CD, the eDrawings, they can see the assembly of watch 3D from all angles, and also include
machining file in DXF format GAL and GRL is also included.
NOTE: The clock lighting LED, you have to use on special occasions, because otherwise the clock battery is
exhausted very quickly.
Tools required to mount the sundial:
Drill, punch and drill bits
Jigsaws
File Set
Welder
Tin
Flat pliers
Pliers
small screwdriver
Termo-folding machine to bend the plastic, or a hair straightener

This watch allows the user to know the time
As the clock must be fed directly or indirectly by the sun
The clock should have minimal impact to the environment
Has to be stable on any support
The clock must be easy to use
The clock should have lighting support
The clock has to be affordable
The time must be able to read at night without difficulty
NOTE: From this list, the teacher or tutor will open a shift of ideas in order to bring students to choose the
materials, forms and colors, technical solutions and applications in order to better respond the criteria
described functions.
In this technical manual it presents a solution but there are many. It is a simple, easy solution to install using
electronic equipment for controlling the battery. It has sought an aesthetic solution to cut Plexiglas, but can be
used any other design and material.
