INTRODUCTION
Elecricity Generating Dance Floor converts the movement of the dancing
crowd into electricity and uses this power to change the appearance of the
floor’s surface. The dance floor can also give feedback to other systems that use
electricity, such as the sound system, motivating the DJ to outperform
his/herself by responding to the energy generated by the crowd.
The floor can have different platforms, providing unique visual experiences on
every energy level, from loading and average, to the maximum level of the
evening, ultimate high! All visuals are a continuous real-time interaction
between the clubbers on the floor made visible, allowing every individual’s
actions to contribute to the collective experience. With the option to change
both its color and shape to match those of your brand and logo, the dance floor
can be modified entirely to your needs.
DEVLOPEMENT , OVERVIEW AND TECHNIQUES0
Overveiw of the actual project that is to be implemented:
The modified way to make DJ dance floor contains a rack and pinion
assembly connected with spring mechanism to uplift the stage always.
Whenever the person jumps on stage, the rack moves to downword direction.
Its pinion is connected to an alternator to generate electrical energy. Stepper
motors are connected to this pinion assembly to generate more power as it
consist of four coils in one. One can charge the battery.
Racks & Pinions Technical Information
RACK MANUFACTURE
Reliance standard precision racks are produced by a thread grinding process,
which generates teeth of helicoidal form. This provides two distinct
advantages: very good pitch accuracy and sufficient tolerance of meshing
conditions (within 0.25º) to make high precision alignment of the pinion
unnecessary.
This feature will be appreciated from the diagram below. Slight misalignment
of the straight-tooth pinion, in terms of deviation from a true right-angle
between the axis and rack in either plane, results merely in a change of
position of the contact points across the face.
RACK STANDARDS AND TOLERANCES
Reliance precision racks are offered in four basic grades of accuracy through
most of the range, please see the individual product pages for details. Grade 4b
has been introduced to offer a lower cost grade 4 where a single rack is to be
used in a nonbutting application.
The tooth form is generally in accordance with BS 4582 part 1. fig 1. for
metric racks.
Bearing Capacity
When linear bearings are used with the hardened round bar racks the
capacity of the support bearings needs to be considered. Where possible the
bearings should be positioned with all the ball rows running on the rack shaft.
However, it is important that the balls do not run on the edges of the teeth. If
necessary the 5 and 6 row bearings can be used with 1 row above the teeth. In
this scenario, the manufacturer’s ratings apply with a modification for the
direction of the load application.
Lubrication
Lubrication is not required when using PEEK™ polymer pinions. For other
combinations unlubricated systems are not recommended. Measurement
applications should use a very thin coat of light oil, in many machine tool
applications stray cutting oil is sufficient. Grease lubrication is recommended
for higher loads, but care should be taken to ensure the lubrication is not
thrown off the pinion at speed.
SCOPE OF PROJECT
The wind and the sun produce energy -- this is something we all know.
Alternative sources of electricity are high on the world's energy agenda. Now
there is a way to produce electricity by dancing.
The dancers move to the rhythm of the music on a dance floor made from
panels that also move up and down -- no more than one centimeter --
depending on the movement and weight of the dancer.
The motion of the surface activates a system of specially designed dynamos,
located under the floor, which transform the mechanical energy of the
dancers' movements into electrical energy.
That electricity is used to illuminate the panels of the dance floor and a
column that indicates the level of energy produced by the people dancing.
