Dear y_man;

Follow the principal recipe in the third Link given:
  -  Start with a 1 molar KCl solution of enough volume to fill 3 or 4 bridges.
  -  Heat the KCl solution near to the boiling point and add slowly 2-3% wt/v agar and heat till a clear solution.
  -  Fill your bridges and let them slowly cool down. Add always solution to keep the bridge really filled during cooling down.
  -  Finish.

Good Luck!
