Tasks for Week 8

• Goals For This Week
• 1.   Find the best way to make the equipments
  portable. Easy to set up and put away.
• 2.   Research and finalize the fabric material
  and have one wall built.
• 3. Connect all the Mic and Arduino board together
  in the can and have it working, work closely with
  the sound team and test out the recording.
• 4. Research on visual programming (Flash or
  Maxmsp).

• Process of Building a Portable Room
• What is needed?
• Rope (can be purchased at the dollar store for
  1.00)
• Pipes ( can be purchased at Home Depot )
• 10 ft long white pipe for 2.59
• Pipe connectors 1 for each wall ( can be
  purchased at Home depot for 0.51 each)
• Binding rings ( can be purchased at Daiso for 2
  or staples for 5 ) or alternative shower curtain
  rings at the Dollar store for 1.00
• Shower curtain ( can be purchased at Walmart for
  3 4)
• Bed sheet (can be purchased at Zellers, Double/
  Queen size 14.97 , Twin size9.97).
• White thread and needles ( can be purchased at
  Fabricana ( around 5-7)

5
How to make? 1.) First we will seam rip the
threads on the top of the bed sheet with a seam
ripper. Then we will trim down the size of the
bed sheet so that the width fits perfectly with
the shower curtain. Then we will fold 1.5 cm of
the edge in and sew a straight line, then we will
match the top edge of the bed sheet to the
section underneath the holes on the shower
curtain and we will sew that together.
6
2.) We will purchase 2 pipes for every wall, and
a pipe connector with it. We will have the
connector in the middle connecting pipe 1 and
pipe 2. Then we will use binding rings and clip
them through the holes on the shower curtain.
After that, we will slip the binding rings
through the pipes to hold up the curtain and bed
sheet.
Binding ring sizes will depend on the radius of
the pipes that will be purchased
7
3.) Then we will tie the ropes end to a pencil
and put it through the pipe. Once that has been
done we will tie the rope a long the ceilings
pipes. Note 3 people will be needed for this
process, 2 people on the ladder holding both ends
of the pipes (pipe1 and pipe 2s ends) and 1
person in the middle working his/ her way on
tying the rope around the pipes. ( First, the
long rope that went through the pipes are tied,
then we tie little sections in between so that
the wall does not sway side by side and is
balanced.

How our installation will look!

How is it portable and how does it work?
In order to move the walls around, first we will
have to remove the rope that is connecting the 2
pipes together. After we have removed the walls
pipes from the ceilings pipes, we will remove
the connector for pipe 1 and pipe 2 and slide the
binding rings off. Then the curtain is completely
removed from the pipes, and then we can fold the
curtain and the pipes and pipe connectors can be
placed in a box and move it to our cars.

Report on Gun Prototype

• Construction
• This custom-made device consists of the following
  major components
• Can-gun a plastic tool designed to ease the use
  of a standard spraycan
• Laser pointer a typical Class 2 laser pointer
• Switches electrical switches installed to
  trigger the laser and external devices
• Can a custom-fabricated, externally-attached
  metal container to house stuff, such as an
  Arduino micro-controller board

17
Gun 1 This is the initial prototype. The core
of the laser pointer (optics laser diode
circuit) is extracted from the laser pointer
device, and installed into the top-rear end of
the gun. Slots/holes are made to create a clear
line-of-fire. Since the switch that came with the
laser pointer is un-reliable, a standard
(momentary, normally open) micro-switch switch
has been used. This type of switch is designed to
be actuated by the physical motion of mechanical
devices, like the trigger of the can-gun. This
switch is wired to a pack of three button-cell
batteries, and the laser pointer itself. Another
switch, designed to interface with an Arduino
micro-controller board, has been installed. This
switch is a miniature tactile switch. The switch
is installed close to the trigger, which allows
actuation by the thumb of the right hand. All
components are fitted either by friction-lock or
hot-glue. Wires are standard 24-AWG insulated
wire with copper core.

• Gun 2
• This is the revision of Gun 1. There are several
  minor changes. Firstly, the miniature tactile
  switch has been relocated to the center of the
  pistol-grip area, so that there is space
  available for a microphone module. To gain extra
  space inside the can-gun, a sub-miniature
  micro-switch is used instead. Wiring is
  identical, except that resistors will be added
  for ease of interfacing with an Arduino
  micro-controller board.
