the best resolutions is with a potentiometer, the resolution is infinite. With a potentiometer, we can use all the input resolution 'of the AMC.
the higher the resolution is important, better the result will in games.
so, why choose something other than a potentiometer, the resolution of the potentiometer is much better! more resolution is perfect, but decrease the result with a less accurate sensor is mess up / deteriorate the performance of the AMC
The potentiometer is based on contact of the wiper on the surface of the resistor, it will get worn fast for such application. And there is the noise issue, these potentiometers are prone to electrical noise the more resistance the have. That is the reason that many joysticks use 1k or 2k potentiometers, to avoid noise, and the resolution then is enough for the 128 - 512 points they provide.
If you really need better resolution and no electrical noise the only solution is the quadrature optical encoders but the hardware related to them is too expensive. I recently bought a US Digital encoder 2500 CPR resolution for the steering wheel project that total cost was $150 !!
I have just thought again about sensor resolution.
Please correct me if I am wrong.
Most of the sensors are claiming 12 bit resolution, I guess it's 12 bit per revolution.
That means that a 180 deg sensor has about 2048 increments. 160 mm crank shaft is giving me approx. a course of 500mm over 180 deg, which means that the smallest increment is 0.25mm with 180 deg sensor.
With another example of 12 bit/1080 deg multi turn sensor, the same course of 500mm has to be divided by 12288 which is giving me a smallest movement of 0.04mm or even 0.01mm with 3600 sensor.
Considering the precision of our gearboxes, I am asking, if it will bring a benefit to go for increments smaller than 0.25mm?
dureiken: Hi there, it's really quiet here someone could help me for my 6 dof project ? thanks a lot

tronicgr: dureiken Hi, Open a thread and I'll try my best to help. A little busy with Kickstarter details at the moment but I'll see what I can do.

fimmy: How's the firmware going?

tronicgr: @fimmy I had to put it on hold to finalize the manufacturing of the new kickstarter controllers. I tested parts of it to ensure compliance with the new features and looks good so far. I'll get back to it soon for integration.

Theuns: Very nice design.I'm also busy with mine and changing it also to Linear Actuators with 220v Servo motors.I'm waiting for my new controllers from Thanos. If I may ask Do you have any Sketchup files of your design and willing to share it I Thanks Theuns

atayeu: Hey everyone! I'm reading up and gathering all of the intel I can find for my first motion platform. this is by far best information for creating one.

tmcnam: I must be crazy but I still can't find the blueprints to the platform by GA-Dawg. Any help would be appreciated. Thanks guys.

Trip Rodriguez: Sorry tmcnam, the shoutbox doesn't get much attention. Did you find the blueprints? They are at the VERY bottom of the extremely long first post. It says "attachments: 6DOF.zip
