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.

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.

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.

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
