To Do

• Fix some cables

Cables

• There were 2 cables I made the other day that turned out to be bad (I was stupid and didn't check them)
• Koch feel that soldering causes micro-bridges to form that can cause shorts
• I rechecked all the homemade cables currently used in the optical lab
• 2 of the most recent were bad and one from a long time ago was bad
• Koch wants me to try to fix them, but this time, crimp the gold needle onto the wire instead of solder, then try to remove said needle by hand
  • Koch wants me to look up, on the internet, how others do their cable making
  • The 2 videos on YouTube that I watched demonstrate the technique using a crimp tool
• The wires are all now fixed and ready to go. I even screwed the cables back into the DAQ card
  • I will return these cables to the Optics Lab and place them on the black table near the tweezers so that a qualified professional can re-install them
