Pictures/video of your boat working
The above information must be typewritten. Using a wiki or word editor is an excellent idea.
You can host photos in lots of ways. flickr.com(yahoo), picasa.com (google), bitbucket, shutterfly are some of the free hosting options for photos.
You can host video for free in several places: vimeo.com has a weekly limit on uploads and provides a link to your video. Others include: google video, youtube.com (blocked by the school filter)
We can do a public demonstration of the project, at one of the schools nearby or here at DHS.
Botball Announcement
LOOKING FOR ANYONE WHO WOULD LIKE TO PARTICIPATE IN UMASS LOWELL's BOTBALL ROBOTICS TOURNAMENT on SATURDAY. Will look great on your brag sheet. FIinal build is Friday afternoon. We'll be leaving the competition at 6:30 Saturday morning and will get back at 6:30 Saturday night. If you would like to join the team, please see Mrs. Lewis or Mr. Connors for a permission slip.

Robotics event
Here is the plan:
I will be available tomorrow for a marathon build and planning session in room 234. Liz says that I am free all afternoon and evening. We should be able to get it programmed and built pretty well.
Saturday is an all day thing. We would leave very early in the morning and come back in late afternoon, early evening. The location is in Lowell.
At this point I see a few levels of success:
1. Going with a group of kids so they can see what it looks like to be involved in an event like this.
2. Not coming in last. In these events, you have a lot of opportunities to make changes on site. It is definitely possible to beat the team that doesn't show up (see #1)
If you could get the word out, that would be great. Friday afternoon in room 234, Saturday early. Permission slips will be a must.

Working in groups of two or solo, you will create a design, plans and other documentation for a patent for a device.
You will need to create plans for making the boat and boiler.
Make instructions for making the boat and boiler.
Make instructions for using the boat and boiler.
documentation of your process for making the boat will help.

Use the information in the chapters to give you ideas on how to redesign your boat and boiler.
Differences between hydraulic and pneumatic systems:
power and speed
Differences between closed systems and open systems
tires, pump, brake system, refrigerator, air conditioner, car's cooling system, car's heating system, dust vent system,
color coding for heat: blue is cold, yellow is normal, red is hot
color coding for pressure, blue is low, yellow is normal, red is high
Dust Control
We cannot run the shopbot through wood until a dust collection system is connected to it.
Bench hooks
Mrs. Leydon needs some bench hooks for her printmaking project.
Could be wood, could be metal.
2-25-08
Did you get your two boats done and checked off before vacation?
Cleanup is an issue. Tools need to be put away. Debris from your work needs to be cleaned up. There is paper that can be used on the tables if you are doing messy stuff.
First two chapters of the reading is due on the second day back after vacation (tomorrow)
2-13-08
Your first boat should be checked today. You should make a press formed hull and new boiler for a second boat by the end of the week.
2-12-08
First boat:
You should have your first boat complete and functioning by this period
The first boat should have a brake formed hull - cardboard is bent into shape
You should have a second boat complete and functioning by the end of the week
The second boat should have a press formed hull - metal is pressed into shape
You should experiment with the size and shape of the boiler.
