Do a resistiv layout

Hy,
I'd want to realise a resistiv layout on a board circuit. On this layout, a contact metallic will move to drive a DC motor.

I know this layout is with carbone or graphit.

Do you know how can i do?

Sincerely

Re: Do a resistiv layout

Resistive tracks for pots on pcb's and the like are usually screen printed on, you can make your own screen print easily enough, but where you'd get the conductive 'ink' from is a tricky one.
You'd also be better using a transistor to buffer the output of the 'pot' as the current drawn by a motor would need a very low resistance and a very wide track.

Can you explain to me how can i make my own screen print.

Thanks.
