Sounds very good. I'd love to have this mod. Count me too!

I wouldn't be able to figure out how to connect the individual component. Am I right in assuming that your code just measure the resistance across the axis? I could easily wire up a playstation joystick controller and I could model a mount for it. Where did you get your board by the way? I can only find chips.

This is not suitable for ones that want a more affordable alternative?

A PS3 like analog mini-stick in small PCB controller with output in I2C, 3.3v. Probable require remove the stick from the board for fit inside the grip.

I too would be interested.

So look what arrived this week:


First impressions looking really good, many of the small issue with the DACO sensor are fixed by this one, much more compact and seems to perform better sensitivity and centring wise overall.

I’ll get on with the 3D part CAD and PCB soon and hopefully will have a something else to show in the next few weeks.

Just a quick reminder in case anyone has missed it: By fitting this you would lose the centre button on the original sensor (throttle switch 1), but I’m thinking i'll make to connections to it available on the finished PCB so you could add another switch somewhere if you still wanted it.

What a thread to combine my passions - quadcopters and DCS input devices! I've been looking into using the 462 to make a better radio controller for all the reasons people love the FSSB. Based on your quick observations, does the 462 have enough stability/precision that (with appropriate attachments and thumb/fingertip controls) you could use it as a flightstick - e.g. how easy do you think it would be for a user to hold it at a specific X/Y percentage value?

You share the same passions as me then!

First impressions it’s very nice, but compared to some nice hall-effect gimbals in say a Taranis, I don't think it would be better, and it would be 5X the price minimum.

The main advantages of a force sensor as far as I know are lack of moving parts and usability under high G loading, neither of which are really issues with RC radios (admittedly also not issues with flight sim gear, but still).
Also probably not ideal for holding at a constant position, nice for fast corrections, but holding in a constant position tends to get a bit wobbly (think F16 vs Airbus).

I don’t think I’ll be swapping out the gimbals in my DX6i anytime soon... but if you want some help working something out just PM me and I’ll help you best I can.

This we can then do by simply adding a button to it, correct? Your frankly excellent tutorial on instructables lists it the relevant pin as being a internal pullup pin (high), so would simply sinking it to the ground with any type of momentary switch suffice to register a keypress on this front? Would debouncing be required for this switch or does the internal hardware already affix for this?

If as such, we could add our own 3d printed bracket with a mount behind it for the momentary button in question, though provided that the 462 does provide the ability to be pushed down and not register that as a force press to slew the sensor around: do you think such a thing will be possible?

My first prototype 3D printed sensor mounts and hats arrived this week from Shapeways. Unfortunately they don’t seem to do a light grey plastic, so I went for red to match some of the other switches, I think it still looks really good!

Everything’s progressing nicely, just a few minor adjustments on dimensions to get everything to fit together easily and it should be good.

Next step is finish PCB and send to fab.
