New estim tracks for CH videos

[diglet]

I implemented a 'nice' serial to restim script a few days ago, it works well with faptap. The idea is to use com0com to present a virtual serial port to faptap, and some code to convert virtual serial to websocket for restim. It performs automatic 1d-to-2d conversion too, but this part will probably not work with VAM.

Will probably publish tonight or tomorrow.

The long term solution is to use buttplug for faptap, but this requires a bit more effort.

Release v1.4.0 contains a method to listen for serial input.

To use this functionality, you must have a virtual com port. This can be done with com0com (download here) on windows. Configure com0com:


I think the "use Ports class" is important, this may require a system restart.

After you added the virtual com port, you can connect faptap to an OSR device at COM19 (doesn't work in firefox).

I have been spending a bit of time on 4 and 5-phase signals, I found an interesting problem with 4-phase and higher signals. (warning: topology lecture incoming)

To explain this we first have to take a step back into the three phase world. We talked about the three independent degrees of freedom: alpha, beta and volume. It turns out there is a fourth degree of freedom we have missed all along: the voltage over the three phases can move clockwise or counter-clockwise. This is a discrete degree of freedom (i.e 0 or 1), how do we smoothly move over this degree of freedom?

Ignoring volume, the freedom space looks like a coin. One side of the coin has the phase diagram with all clockwise threephase signals, the other side contains the counter-clockwise signals. At the edges, all signals (at the electrodes, not the left/right channel) are in-phase therefore the signal is neither clockwise nor counter-clockwise. This means that we can walk around on the edges of the coin to switch from clockwise to counter-clockwise, but it's not possible to move through the coin, if that makes sense.

Obviously, this is kind of a joke. We don't really care if the signal moves clockwise or counterclockwise. The timescales are too small to matter. Scripting this would be terrible. I may run some tests later, to confirm there is really no difference in sensation between clockwise and counter-clockwise signals.

Back to 4-phase signals. With four or more phases, the direction plays a much larger role. Take a look at a four-phase circuit:



Recall that when the position is at the center, the amplitude of all electrodes should be the same. With three phases, there are clockwise and counter-clockwise signals that satisfy this constraint. Four phases, all kinds of different solutions turn up, for example these two oscillation modes both satisfy the constraint that all electrodes have the same signal intensity:



I think there's a good chance these two modes will feel different, but there are discrete states so interpolating between them is not possible. And of course for 5-phase, it's even worse. Yuk.

The extension to 4 and more phases goes as expected, meaning the trail of equations has reached a dead end, I have absolutely no idea how to proceed. (I don't know why I'm working on this. I don't even have a box with more than 2 channels).

When you say degree of freedom, are you sure that you can move on that axis without having to move on other axes? I think you are referring to something like "potential way to cause unique type of sensations", but I am not sure it is a real "degree of freedom".

[diglet]

Yes, because these two (electrode) signals are clearly different, despite having the same volume and alpha/beta.



The tricky thing is that the freedom space is discrete, there is no way to smoothly transition from clockwise to counter-clockwise phases, except on the edge of the phase diagram (or when the volume is 0).

One could argue that counter-clockwise is just the negative volume, time or frequency component of clockwise. But that explanation only works for 3-phases.

The knowledge in this thread has gone beyond me. @Diglet when you're talking about 4 and 5 phase are we talking about discrete signals? As in surround sound? With 4 or 5 electrodes?

Once again this could be game changing. It would surely enable you to emulate the different axis you get with the robot strokers, and the multi-axis scripts being written for them currently... i.e up/down, pitch, roll, sway, surge and twist?

Imagine even just 2 x additional electrodes and the ability to rotate current around you, clockwise and anti-clockwise, i.e a twist feeling?

I'm happy to test... I see you can buy a small 5.1 external sound card with discrete outputs on Amazon for £8!? thats a tiny investment compared tot he strokers.

BTW - The Oculus Quest 2 turned up - cost £150 on ebay... using in VAM is totally immersive... Being able to walk around, touch and 'interact' with a model in VR is amazing... and to be able to feel her via Restim... mind er... blowing.

This pretty little elf.. gave me the best blow job.

Whoa! That lot certainly blew my mind.
What is VAM?
I would love to understand more about all of this, but know where to begin!

Really cool piece of software! Was playing around with the calibration a few days ago, but unfortunately I couldn't find anything to connect it to since MultiFunPlayer doesn't work on Linux. Anyone know of some alternative that can send it signals based on funscripts? I suppose I could try some offline conversions but a live player would be nice.

@diglet sorry if I missed some post where you already talked about this, but have you considered adding a calibrated control channel for carrier frequency? Though perhaps modulating it would mess with the phase alignment.. I did some experiments in the past, and in the end it turned out that people experienced different frequencies quite differently. It seemed like the presence of a parallel resistor in the DIY stim box had the biggest influence, but there were some individual differences too.

[diglet]

I haven't tested restim on linux, I'm pleased to hear it runs at all

Maybe JoyFunplayer works on linux? You could also try intiface desktop serial output. I recommend intiface central over the newer intiface desktop because the former has a GUI for configuring the serial output, intiface desktop requires some fiddling with configuration files.

Not sure which video applications on linux are capable of sending command to intiface/buttplug. scriptplayer + VLC? I think faptap.net should also work, both with intiface and direct serial (OSR) output. If you use serial output, you should manually configure a virtual serial port (https://stackoverflow.com/questions/521 ... -for-linux). You can test the port by sending a few commands to restim: L010 or L099.


What do you mean with the calibrated control channel? I only notice a small difference between different carrier frequencies, changing the frequency has a large effect on volume, but a small effect on the type of sensation (I tested 500-1000hz on DIY box).

The knowledge in this thread has gone beyond me. @Diglet when you're talking about 4 and 5 phase are we talking about discrete signals? As in surround sound? With 4 or 5 electrodes?

Yes. 4-phase means 3 audio channels, connected in such a way that there are 4 independent electrodes.

[Niceguy_LondonUK]

Hm.. sounds like an interesting prospect. I was thinking, why stop at 4 signals/electrodes? I figure you need 6 to be able to move the signal and therefore the feeling around in 3D space. One for each side of a ‘cube’. This would allow you to move the signal up/down, left/right, forward/backward, pitch, yaw, rotate/twist. Scripters are already writing multiaxis scripts in this format to load into MFP.

Niceguy.

can i ask on the restim and then loading into Multifun player, how do i get the estim signal sound out to my 2b box? i have the video audio playing ok and can see the estim heat map but not sure how to get the estim signal to the box. Any help appreciated.

Cheers

Have you looked at the restim wiki?
https://github.com/diglet48/restim/wiki/mfp-setup
Once you have the MultiFunPlayer configured to: add restim as a device, have the funscript signals (L0 and L1) output to restim (via the websocket option), you should be good to go.
It’s important that your computer can output two independent audio signals: one from the video-audio and another from the estim audio. I do this by having the video-audio sent to my Bluetooth headphones and the estim audio sent to the standard computer speaker / headset jack.
I hope this helps. It took me a while to figure out all the Ins and outs of multifunplayer and restim, but believe me, it was worth it! K

yes

I’m struggling with getting the output to the estim device? I can’t see 2xoutpits anywhere or anywhere to select. Have a usb audio device and the standard jack device.

[edger477]

I can’t see 2xoutpits anywhere or anywhere to select

the output of estim from restim is configured in restim



If you haven't selected it then you haven't done the calibration yet. Or read the manual :)
