Dear All,

I have some Graupner linear servos that I would to use however, they are negative pulse type. Anybody have any pulse inverter schematics which can be posted. I recall Ace R/C had an pulse inverter but I don't think they produce it anymore.

Thanks for the help.

You can, ,if its a logic type signal, just use any CMOS inverter or inverting gate.

This is cool because you can do 6 channels in a single package.


Or were you after something to go in the servo?
