    as above can anyone recommend a place to get the above joystick about 60mm high not very big.

    I have this servo stick.

    if your wanting electric proportional then you need to know exactly what the output signals or you got no hope of it working.

    its an electric one i am after. it's a project i am trying to convert a valve to proportional. i am not sure of the outputs tbh

    Is it to drive a hydraulic valve control solenoid?

    yes that's it that's what i am trying to do

    Have you a valve in mind?

    its a hitch valve from a case ih mx 110

    Will an on/off electric valve not do, I must be missing something?

    i won't have enough control i don't think with an on-off type switch.

    Hydraulic supplier such as Kramp (or even E-Bay) will have joy stick and valve solenoid to match each other.
    An expensive solution to a problem.
    Kramp will only supply to your nearest dealer, but worth looking at their hydraulic catalogue, if your own supplier cant help.

    As @Mursal says, big jump from simple on off solenoid control to full blown proportional control. The valves require proportional drive solenoids and electronics are required to control them and provide feedback and positional control. The joysticks etc are the “easy” (cheap) bit! Have fun.

    The easy bodge way is to use the controls from a hedge trimmer, Mcconnel XTC ?.

    for an interesting journey look at RC toys and scale up

    Too complicated. Integrating the optical sensors with voice operating system and calibrating the touch sensitive
    receptors can be a nightmare to calibrate, especially if the contact surfaces are not cleaned with alchol first

    are these 3 position proportional solenoids what is used in a teleporter these days

    anyone got a link to the valve solenoid to satisfy my own curiosity

    It all depends what you are trying to do. You don’t need position feedback for all applications. Just a solenoid valve which will work of a PWM signal which you can drive and program via a £20 arduino. Clutch valve on a 40 series sldp works this way. They don’t actually know the position of the solenoid valve, hence why you have to calibrate them every now and then. If it’s for something more critical used in a lifting application, the position control may be required, but again some systems, albeit not very good ones had simple proportional control with no valve position feedback. Matbro TR250 ITL with apitech hydraulics as an example.

    Rs components or Farnell sell proportion joysticks but as has been said before that's the easy bit!

    If it’s only for sliding a hitch in and out and simple on off will do it, just restrict the flow to the hitch ram to make it move slowly, a lot of John Deere’s are like this
