
Basic interest in the technology
Most likely spurred from laser
pointers

Build a simple 200mw laser

Write paper about lasers

Conduct experiments with certain variables

Put together a display with test objects

Create a box/stand to safely display the
laser for the showcase

All parts were ordered
Soldering
Went through 6 DVD drives/burners
Ordered final part (that did not work)
Tried another design
Got more parts
More soldering
Laser did not work
Ordered actual last part
