Roland & Surface mount soldering


2nd try – SUCCEEDED!

  1. Still couldn’t find 100 ohm resistor, so I tested with breadboard first and decided to use 68 ohm resistor.
  2. Extended 1/64 short wire
  3. Replaced some 1/64 with 1/32 to speed up milling



1st try – FAILED!

  1. When wiring 1/64 route for milling in Eagle, I made them too short underneath resistor and LEDs thus made circuits inseparate
  2. Wrong wiring to block the resistor to ground O_O mistake_1
  3. Couldn’t find 100 resistor and used 220 resistor –> too much!
  4. So now it rest on my Failure Wall
