Possibly a bit more readable:

myAutoBeam = {
  \overrideTimeSignatureSettings
  3/4                   % timeSignatureFraction
  1/4                   % baseMomentFraction
  1,1,1                 % beatStructure
  \beamExceptions { }   % beamExceptions
  \overrideTimeSignatureSettings
  2/2                   % timeSignatureFraction
  1/2                   % baseMomentFraction
  1,1                   % beatStructure
  \beamExceptions { \tuplet 3/2 { 8[ 8 8] 8[ 8 8] 8[ 8 8] 8[8 8] } }
                        % beamExceptions
}
