SHELLHOUSE

Technology Engineering Design Project

15 instructional days at 45 minute class periods

Goal of Seminar

Goal of this seminar for instructors is to understand how to integrate STEM into the classroom with a lesson plan and student activities that address state standards in STEM.

Home for the Homeless, LLC is an excellent activity that includes design, marketing, community service, construction, and manufacturing.

Overview

Inhabitable collapsible structure made of cardboardbecomes a shelter able to provide an address to adefined group of unsheltered homeless persons, bymeans of radio devices, proposing a way to makethem visible.

Having an address is how we exist on society,how we become citizens, where we can be located,where we receive our mail, where our family andfriends can contact us.

Overview

A house is where we validate this existence in the

physical space.

A shelter that gives us protection, our intimate

space.

Construction of Shelters

7 Million Dome Homesfor the Homeless!

Cheap Geodesic Domes

For fun we made a Cheap Geodesic Dome for under $50 to be used as a jungle gym. We did a time elapse to music for fun as well, the video and music took twice as long as making the dome itself. protection was added on the joins to the kids don't get hurt

STEP 1 – THE CARDBOARD PLATE

Grabb cardboard from the streets or what you have at home.

Complete a plate of 7,4 x 5,5f. If you put different sizes boxes, be sure to put the stripes along the same direction.

Complete the size however you can, putting them together with strong tape.

STEP 1 – THE CARDBOARD PLATE

STEP 2 – Measure of the Fold

Mark where you will fold.

Each fold has to be of 5,5 width.

Mark lines of this length across the plate, following the stripes of the cardboard.

Try to use the folds that come with the box, remember to follow the stripes of the cardboard, after marking, folding will be in that direction always (accordion).

STEP 2 – Measure of the Fold

STEP 3 – Measure of the Center Cups

Divide the cardboard plate in 2 half's, by making a line in the middle, opposite to the lines you marked.

Then, from that line, mark 6" to each side. You will have three lines: center and 1 line in each side of it.

Use a sharp pen or pencil to mark the cardboard, this will make easier its folding.

Once this, mark crosses across the middle line with the pen. The intersection point of the crosses will be done in the point where the crease goes up, the diagonals will go from line to line.

STEP 3 – Measure of the Center Cups

STEP 4 – Fold as an Accordion

Fold the lines you marked.

STEP 5 – Cut crosses in the middle

Open the cardboard plate: you have the accordion shape and a fold in the middle, now is time to make half cuts in the crosses across the middle line.

Use a blade and a metallic ruler.

STEP 5 – Cut crosses in the middle

STEP 6 – Folding the Crosses

Folding the crosses to make concavities or cups will be as follows: try to get someone to help you to keep one side tight keeping the shape of the accordion, while the other keeps on folding the other half.

Remember to make the accordion shape and while you go through it, the crosses will become cups, folded to the interior of the shape.

STEP 6 – Folding the Crosses

STEP 7 – Re-fold the whole shape

You can put weights on top to keep the accordion shape, while you cut stripes of 5,5f by 5,5". This stripes will help the structure to remain stand-up.

Take the shape and glue the stripes in each extreme.The stripe will go from one side to the other.

Use strong tape to glue them.

STEP 7 – Re-fold the whole shape

STEP 8 – Embed Radio Device

Please go http://www.shellhouse.org/radio.html to get the step by step of how to set up the radio module.

STEP 8 – Embed Radio Device

STEP 9 – Give shelter to homeless

You had built the shelter, the radio device is ready.

You spent $35 in the whole experience, learned how to make something from used materials, got something to share about electronics?


Now please mail it to:St. Francis of Assisi Church 135 West 31st StreetNew York, NY 10001

Where the circuit you made, will be programmed and set to talk to hand held receiver

Equipment / Tools

Calculators Utility knives Hot glue guns Tape measures Protractors

Supplies

1 solderless breadboard, you can buy from Jameco Electronics.

1 - 9 volts battery and its adaptor

Supplies

1 XBee™ ZigBee OEM RF Module, buy from Maxtream.

Breakout Board for XBee Module, buy in Spark Fun.

Supplies

Female socket and Headers (for sodering zigbee to the break out board), buy in Spark Fun.

3.3 voltage regulator, buy it on Sparkfun. (from left to right, like it appears on the picture) Ground-Output-Input.

Supplies

# 10µf capacitors buy in Radio Shack # 1µf capacitors buy in Radio Shack

LEDs, Switch, hook up wire buy from Radio Shack

Supplies

At the end it will look like this.LEDs and switch are not neccessary, since you will turn it on/off, you won't program the radio so LEDs won't blink.

Procedure I

Solder the XBee RF Module to the PCB breakout board as shown. The white letters should face down, away from the XBee Module. Be sure to leave enough space so that the headers do not touch the back of the module.

(radio -female socket-breakout board- headers)

Procedure 2

Set up the breadboards with the xbee radio module, the 9V to power the XBee radio, add the 3.3 Volt regulator with the capacitors.

Be sure to test the in and out voltage with a multimeter (optional, very useful, buy from Radio Shack), Remember the incoming voltage has to be 5V and 3.3V out.

Procedure 2

This simple setup will allow you to get started with Xbee radio modules.

This should help familiarize you with how the radios communicate, even though you won't program it yet.

There's PLENTY more features on the XBee including broadcast modes, data enveloping and mesh networking. Learn more about xbees on Rob Faludi's blog - ITP

Assessment

Students should conduct anonymous peer to peer evaluations for everyone within their team

Students should conduct a self evaluation for themselves

Also have the students evaluate their own project Teachers should assign a group grade and base

individual grades upon the peer to peer evaluations

Assessment

Teachers should also grade the finished project A low wattage light bulb and thermometer inside

a model could test the projects ability to retain warmth

Testing a full scale unit would ideally be tested by sleeping in it over night during the winter (probably not an option)

Rubric (Peer to Peer and Group Evaluation)

Peer to Peer grading ideas

– Willingness to work– Works well in team– Leads or follows– Exhibits constructive criticism– Effort of work– Motivation level– Safety– Contribution to group– Rank peers from most

productive to least productive

Teacher to group grading ideas

– Safety– All members contributing– Organization / Planning– Compromising or

Demanding (for unsettled issues)

– Did group need constant assistance from teacher or were they able to determine issues for themselves?

Rubric (Constraints, Finished Project)

The following should be considered as graded constraints:

– Rigidity (sound construction)– Portability (folding, ease of

transport)– Venting / Lighting – Resistance to moisture and cold– Size (recommended to house 2

adults and 2 children)– Budget (how much to produce a

single unit - $500 maximum cost)
