Alternate Wiper Motor approaches

[sirnoname]

The logarithm scalers where added to make a linear movement from SCN5 to a circle movement like wiper.
More movement for the small accelerations, less movement for the higher accelerations to let feel you something without cut something. The movement is limited.
Of course it can also be used in the opposite meaning.
Thats the difference to other software, everyone can setup his own ideas with no limitations.

@yokoyoko, great stuff, I haven't progressed that far yet - thanks for pointing out the capability!

@BobBuilt, thanks for the info, I appreciate the detailed data backed up by someone who has experienced the results. Seems to align with what I was concluding from my own calculations. Wiper motor (and other wormgear) solutions should be very capable if designed well - and I guess many have already proved this with their own designs! I am still keen to explore alternate connecting methods though (if I come up with any useful test results will pass them on, just experimenting at this stage, if not will fall back to the tried and tested).

@sirnoname, I am so excited about getting some gear together to try out a sim of my own especially when backed by such excellent and comprehensive software. It is fantastic that this level of quality is so readily available to the DIY community and with such great support! Well done and thanks.

So in summary so far we have:

Increasing the wiper motor arm length will (for a constant motor speed)
- increase speed generated at seat, and
- increase the maximum movement of the seat, but
- the motor has to do more work to move the same mass (person)

Decreasing the wiper motor arm length will (for a constant motor speed)
- decrease speed generated at seat, and
- decrease the maximum movement of the seat, but
- the motor has to do less work to move the same mass (person)

Moving the motor (more importantly the connection to the seat) away from the seat pivot point will
- decrease the maximum movement of the seat, but
- the motor has to do less work to move the same mass (person)
(Note: it doesn't really matter where the motors are positioned - it is the tangential distance between the seat pivot point and connecting rod that makes the difference)

Moving the motors (more importantly the connection to the seat) closer to the seat pivot point will
- increase the maximum movement of the seat, but
- the motor has to do more work to move the same mass (person)
(Note: it doesn't really matter where the motors are positioned - it is the tangential distance between the seat pivot point and connecting rod that makes the difference)

I guess one of the best stuff about wipers is its cost... you can get them almost for free in a car junk yard, depending in the mode of the owner...

but wipers are small... last week i went to my local junk yard, and the guy in charge, told me that he found me a nice couple of huge bus electric wipers... that runs at 12V... i want to see them if i get lucky i will post

but with wipers, they need to be properly earth isolated from their casing.

Finally found some time to setup x-sim on my laptop and get it talking to the game... Yay Not sure I fully understand the setup process just yet, Its hard without the motors connected to see what's going on.

I now have motors, Arduino (running X-PID), cheap ebay power supply , decided on a design and just about completed plans.
Still waiting on the H-Bridge drivers and need a visit to the hardware store.

Hoping I can clear some time over the next few weekends to make some progress!

I am curious, when using Arduino X-PID or similar have most people found running the extractor and converter on the game PC works OK? My initial tests seem to indicate it is OK but was wondering if I will have problems. Its an AMD A4-3300M with Radeon HD6480G - budget laptop.
