The Maida does work but it is easy to damage it. Both of the circuits you included are NOT short circuit proof. The slightest slip with your crocodule clips and the regulator dies. The 317 version can even fail if there is no load!
IME it is better to build the Maida reg with no capacitors on the regulator IC 'in' or 'adj' pins. Those capacitors just create problems.
