I made a (crapy) tool to manually create and play video synced sequences for the Fredorch F21S.

The positioning mode of this machine does not work satisfyingly with standard funscripts. It is rather intended to receive a tuple of two speed values (in/out) and two endpoints and then it goes to work. There is a converter (whose link I do not find at the moment) and a player script in the xtoys app, but I never managed to get good results from funscript conversion.

So with serious help of AI I have thrown a tool together, that does the following:

• Play a local video file
• When stopped, lets you create a movement pattern (the above mentioned tuple) that is supposed to be loaded to the machine at the stopping time
• Import/export of saved sequences
• Edit the points
• Connect to your F21S
• Test a parameter set on the machine
• Sends the movement data with a configurable lead time when the video plays and fucks you like the person in the video

Clicking on the points in the list and on the time scale lets the video jump and preloads the parameters of this instruction. Be aware that clicking the "add point" button will not overwrite any points. To edit them, go directly into the list below.

I believe, there should be a time of at least one second between instructions, but nothing catastrophic will happen otherwise.

The meaning of the loop parameter is not clear to me, but I kept it in the interface. Keeping it 0 works (and the machine loops).

This tool does not work with links from tube sites, local video files are required. I think, this is not fixable. But you may find a way to download from your favorite site to your harddisk. I also believe that the positioning restrictions are not correct, but it works good enough for the moment.

The tool is available here (in German, but the automatic browser translations look good to me):

There are two patterns in this directory (and the links to the videos, which you must download somehow for using them, is in the beginning of the file):

https://f21svideotool.freedev.app/patterns/

One very short for testing and one longer one with lots of rythm change. I had lots of fun creating and playing that. I think I needed 30 minutes for 15 minutes of video. Don't be overcritical, this is not an accurate science.

Credits go to these guys for documenting the F21S protocol:

Since I managed to get my entire hand in my wife's pussy for the first time in 2021 or so, fisting is our regular sexual activity. I am however always using my right hand for fisting, which is my dominant hand. My wife requires to be seriously and deeply punched to get off. I repeatedly noticed that I can easily fist her cunt to pulp with my right hand and that I sometimes have to add my left hand around my wrist to achieve at least some friction in her sloppy mess, but I am for the life of me not able to fist her with my left hand. This is funny, because it is obviously not her capacity. I even measured my hands, but they are very similar. So it must be that I am too stupid for the proper motion with left. I try to train my left hand now because it would be nice to alternate hands from time to time. Not looking for advice, just wanted to share this observation and maybe there are other fistern who can only do it with one hand.
