All issues reported so far with the FF1 have been due to either a cold solder joint or a misplaced component.

General resources

One or more cold solder joints

Make sure all your solder joints form shiny tents that cover the entire pad. Reflow any joints that look less than perfect. See Cleaning Up Solder Joints for more on how to identify and fix cold solder joints.

One or more parts in the wrong position

  1. Double check all the resistor values by their color codes. (You cannot reliably confirm resistor values with a multimeter after they've been installed in the circuit.)
  2. Check the capacitor positions and orientation
  3. Check the orientation of the diodes
