Compared to more than twice that for a used DACO sensor, or nearly 7X more for a new one, (or 20X more for an OTTO sensor if you want to go that way), it sounds quite reasonable to me...

The original sensor was indeed supposed to run off +/-5V, but since it’s just a variable resistor a lower voltage is fine.
Worst case I could easily add some sort of negative charge pump to do the -5, at $100 it would be worth the extra effort if I turned out it needed it.

From what I can tell I don't think it's wired any different than the sensor you're using, so I'm a bit confused on the execution required.

Well, it's more reasonable than the hundreds or more you would spend on the other limited options.

A replacement lenovo keyboard is about £20-£30 on amazon, I'd rather cannibalise a part than spend nearly half as much as my entire throttle for one component.

Manual for the MSI Model 462: http://docs-europe.electrocomponents...6b80bf1d8f.pdf

It is an MSI brand sensor (http://www.ultra-msi.com/miniature-joystick-models.html) so they would be quality items, IF they are what the buyer is saying they are and it is not some sort of scam. I am genuinely wondering how he amassed such a large quantity of them and why he is selling them for such a low price, given that he says they are unopened.

Normal type of this sensor sells for around €550 - €650 EUR (depending on VAT) brand new, which would translate to around approx. 800 USD. Anyone willing to take the plunge?

EDIT: this guy is shipping them from SOCAL, US. So might be a bit pricey for any EU, AS or AF located individuals. I have been digging through Mouser and Farnell to check for any (force resistive) mini joysticks and while they do stock what appear to be quite compatible parts, I cant help but feeling somewhat out of depth as I have never worked with these before. Also, most of them seem to run on 5 volts rather than 3. Any pointers for me, what I should be looking for?

These guys sell pointing sticks, so it might be worth asking for a quote.

And I'd still be more than happy with cannibalising old keyboards.

Looks ideal to me , absolutely cracking find Deezle.
I had actually seen these on RS in the UK but for about 4X the price: https://uk.rs-online.com/web/p/joystick-switches/0419681/ for £100 I think we can make this work. That's by far the best price I have ever seen for something like that.

I messaged the seller and he gave me a reasonable quote for postage to the UK. I'm willing to take the plunge and get a few if I can get some names lined up, for that price I recon I could sell a finished sensor and adapter + 3D printed mount and knob for around £150 + postage, or I will happily sell just the adapter board for you to solder to if you would prefer to buy the sensor yourself.

Anyone who would be interested for around that price either PM me or just reply to this thread.


Cheers

Already got a quote from Sprintek, The SK8702 is now discontinued but they said they still have some for $28.55 + $75 Shipping. None of the pinouts are much help to me as I would be making completely custom analog circuitry anyway, not interfacing with the existing PS2. If you want to give it a go with my I2C code go for it, I'd love to see that working

Are we talking here about a finished drop-In Replacement including Wires and Connectors or does it need to be assembled and soldered?

Thanks

Yes it would be a pre-assembled direct drop in replacement, no permanent hardware modifications needed. Just unscrew the throttle, unclip the old sensor, plug the new one in and then recalibrate.
You could even change back to the original sensor without any problems if you wanted.
