Lesson 6

What Neil was talking about:
• Homework from last week
• Components of a circuit board
• Crystals
• Diodes
• Transistors
• Micro-controllers can't run from a battery that has more than 5 volts
• How to design well a board
• Homework for this week

Homework:
• I do cutted the board in the Roland Modela after setting new X and Y in the Modela software (we used FabModules).
• I wasn't able to solder the board (my hand were shaking a bit), so Dana and Ohad helped me to solder my boards (including the FabISP). Thank you guys!
• Screenshots from Eagle:
• Working beside of the tutorial:
• The first sketch of my board:
• I have added a pushbutton and a LED. Look here:
• The board (after soldering):
• The traces and the interior of my board:
• Traces:
• Interior:
• Download the board schematic, sketch, new interior and new traces here
• [IMPORTANT] If your cut out board looks like this:
  
  Then you got a problem, because the flute of your milling machine will go like this:
  
  And it will (probably) cut your board interior a bit. So, instead of doing that, do something like that:
  
  
• [IMPORTANT] Here's a video about the right way to mill the board (the grey dots are the flute track):
