Long darning needles are super strong and cheap.
Brilliant idea, Sandy. I think I’ll be raiding the sewing kit tomorrow.
PS I’m an Edinburgher, well Loanhead. Though I moved to Australia in 1995.
All love. Stay safe - distance and lots of hand washing

Im from Bonnyrigg. So know loanhead well.
All the best.
What Joystick Circuit did you use for that other module?
at the top of this thread you have the link ![]()
but i don’t understand why there is only one circuit for Y and X, for me it need a complete circuit for each axes …
Edit : i understand now, there are 2 circuit with the TL072 ![]()
Easy peasy. The board on the right inverts the xy outputs. https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/5/59690a55ec26efaa84848af4b75c1e6999bb6d81.png
Yeah that would make sense, but I built the xy circuit and panel first and only thought about the inverted outputs afterwards.
With those game pad thumbstick modules you get two linear 10k pots - one for x travel and one for y travel. There is also a spring that returns both pots to the center. The spring also returns a lever that activates a switch when you push down on the thumb pad. Pretty nifty really.
Anyways, for a synth style joystick I wanted a stick that remained in place - hence the spring removal hack.
The circuit I cribbed sent out 0-5v on 4 pots. I simply reduced it to two pots and replaced the pots with a joystick. If I had left the spring in it would output around 2.5v on both axes everytime you let the stick go.
The results? Rough and ready, but that’s certainly down to the cheap joysick part (and the spring removal) and the simplicity of the circuit.
There are lots of better suited (but more expensive) sticks out there. But then you getting into the “I’d be better off buying a commercial module” paradigm.
It’s also worth bearing in mind that some modules respond to more than 0-5v.
Lots of opportunities for improvements though 
If you are interested in looking at my V1.3 Witches Brew Joystick Schematic based on the CGS joystick.
I made a CV joystick controller and made a Linear LED Voltage output indicator for Displaying the Voltage on a Separate Blue and RED LED. It wouldn’t be that hard too mod in.
Superb! I love your panels close up.
Nice. Thanks for sharing your take on the joystick. Looks like a nice stick in your build.
Thanks. It is funny when I made the prototype panel my silver sharpies did not come in time. So I gave it a few coats of black. Then scratched out the lettering back to aluminum then gave it 3 coats of clear. Don’t know how well it will hold up long term with possible flaking. But it was fun too Give a shot.
The on the mixer module on the left. I did a hydro dip with spray paint. It was cold out when I did it so it turned out like a slightly textured finish.
