GFab. 2.17.2011

• today in the morning we did more work with bread boards.
• we learned how to make a night light with the bread board and some components.
• we used a led, two resistors some black and red wires and a transistor.
  
  
• a transistor is something like a spray can. it holds a lot of energy inside until it is released.
• we also used a switch, that is something like a light switch.
• when light hits it, bright light equals low resistance and low light equal high resistance.
• in the afternoon i did a survey for green fab.
• i also worked on my inspiration page about tree guards, i took all the pictures i downloaded and added them on a ink scape page along with captions.
