What will you do?

What documentation will you create?

What tools will you use?

How will you share your project with the school and community?

How will we know that you have succeeded?

Sub Plan Mr. Connors May 16 2008

 

Principles of Technology Room 136

There are a number of projects going in the class right now. Here is a breakdown of what people should be working on:

 

Andria and Laura - Making a model of Duxbury Jewelers out of foam core board. They should need an exacto from the top drawer of the desk, which they should return at the end of class.

 

Donnie - Building circuits and experimenting with sound generated by his graphing calculator

 

Tim, Seth, Pete - Working on the mill, getting designs created on the computer to be cut in objects.

Tory, Chris, Will, David, John - Working to design for the vinyl cutter. Design for the back of a cell phone. Small designs on the vinyl cutter.

 

If they are cutting today, they will be limited in material to the size of the cell phone. There is some transfer tape on the top of the monitor, They should be aware that the students in the next class also need the transfer tape. They will likely need an exacto knife from the desk, and should return it at the end of class.

 

Nick and Mike - Electricity, modifying remote control vehicles and radios. They may also be using the vinyl cutter to create decals for the car. They should put their work away in a locker.

 

Blade, Aiden, Austin - Using Sketchup to design buildings and phyical spaces. They should make sure they put their work up in the Sketchup Warehouse.

 

Have students shut down computers at the end of class and put their work away.

Vinyl cutter

Original artwork only

Cuts should be less than 6 inches by 6 inches

Check with Mr. Connors if you want to do something larger.

 

Hovercraft

Create documentation of your hovercrafts to show how they work and why.

Take photos and video of them running.

Get them to run on a 9 volt battery so they can be autonomous.

Races?

 

Sketchup

Design for houses, design for the mill.

 

House Design

Hand drawings

Mill

Everybody will need to get some experience running the mill

Make note of any odd things that happen while running the files.

 

 

4-14-08

Aerodynamics and hovercraft

Your designs should be based upon information you have found during the project.

Don't rely only on what you already know

Your construction of this project should be largely complete.

Hovercraft Writeup/documentation

Write up an explanation of how the hovercraft works, what design changes you have made and tips for somebody else to follow if they were to make the project on their own.

Include photos and drawings of the device you have made.

 

Vinyl cutter

Use Gimp, Inkscape or paint to create your own design

Transfer the file to the computer with the vinyl cutter

Cut the sticker, put it on transfer tape.

Use the vinyl in connection with another project (joule thief, hovercraft, mill, etc.)

Vinyl cutter writeup

Is the process we are using to create designs in class written up?

Write up a step by step process for making an original design for cutting in vinyl.

 

Sketchup

Make a simple, small design, bring the file over to the mill and cut it.

What can we design to tie in to the joule thief circuit?

Can we design parts for the hovercraft?

How can we combine the mill with vinyl and electronics through sketchup?

 

Mill

Is the set of directions we started with still valid?

Make sure any documentation we create is posted on the dhsfab.pbwiki.com site

See if you can cut throughout the period

Larger files will take longer to cut

What can we design to tie in to the joule thief circuit?

 

House Design

The idea for this project will be to design a house using CAD such as Sketchup and fabricate the parts of the house to make a scale model.

 

The parts can be cut on the mill, shopbot or other tools in the shop.

Passive solar design should be a feature.

Electrification of the house should be a feature.

The materials can be wood, foam core board or cardboard.

We can make the landscape of the building with foam and the shopbot to make a 3d landscape.

Several houses can be combined to make a neighborhood.

 

BuDesign

The Boston University College of Engineering has an annual design competition.

This can be a fun and challenging project.

Information about the competition is here - http://www.bu.edu/eng/design/

VinylCutter

If you are making your own design in Gimp, make sure the image is about the size you want the sticker to be. If you have to enlarge the image, you will get a lot of imperfections.

You can also use Paint to create the image you will cut on the vinyl.

 

At this point, we are working with electricity and the DesignProcess.

If you get stuck, find me to get some guidance.

JouleThief

We should be able to make several versions of this circuit. There are a number of ways that you can improve it. There are a number of problems present in its current state. You will need to articulate and solve these problems to make the circuit and its resulting solution your own. Your solution must be more durable than the samples shown.

 

Here are some questions to help get you moving:

What can you put this circuit into?

How can you make this circuit look like it is something else?

Write your ideas on a piece of paper and hand it in.

Have at least two ideas.

Include drawings of what you think it should look like.

Include notes of features you want to add to it.

 

Finding a toroid

Wrapping the toroid

Soldering instructions

Parts you will need for the circuit

Storing your work

Label your work

Where to get information on it

Getting the toroid

Motherboards

Wrapping the toroid

Securing your work - bring in a padlock, you can share a locker

we will likely make several of these each

If you want to use white or blue LEDs, we will have to buy them.

If we are buying, what/how many should we order?

 

How can we modify the circuit?

What can we do to put the circuit into a housing?
