was suggested i go here what i want is hand held remote to operate  mpc, williams postwar  with out eng chips [i only run i eng at time] must have varible voltage [ac] at track would a inverter sw dc power at trk to ac ?? this KISS project is very frustrating esp when williams has simple mtr controll [once again want SIMPLE system] thank you fracon

thank you for your responces  i'v used the aristo rmote on 2 rail o dc  would like same to operate on ac would a bridge rectifier work on the ooutput side of the aristo ??  my qripe about electronics  was about electronics in eng do not want to mess with engs [ i don't like shelf queens] keep it simple i follow train and throw switches onsite power blocks etc  train on a string known as brio brand

ant anything to do w chips or electronics [too expensive and unreliable]
  thank you fjc
