VisualStimEdger

⚡ This is a companion app — it does not generate e-stim signals or audio on its own. You need an existing setup already producing stimulus: Restim, xToys, an .mp3 file playing through a stereo box, or anything else you were already using. VisualStimEdger simply controls the volume/intensity of that existing signal based on what it sees on camera.

Tracks your cock on a camera feed and uses its position — flaccid, erect, or edging — to automatically control stimulus intensity. The goal is to keep you in the erect-to-edging zone by easing off stimulus when you get too close to the edge, and ramping it back up when you start to drop.

Output modes: Restim, xToys (any Lovense/Kiiroo/etc. toy via the xToys browser app), Windows Audio, and a built-in MP3 Player.

Requirements

• Python 3.9+
• A camera feed showing your cock (OBS, a webcam viewer, or any window with a live feed)
• Restim running with WebSocket server enabled, or any Windows audio output device
• Electrodes wired up and ready
• A dick that goes erect when you're close to cumming - this works visually

Install dependencies:

pip install -r requirements.txt

Setup

1. Wire up and get on camera

Get your electrodes attached and your cock in frame on whatever camera feed you're using. The feed just needs to be visible in a window on your screen — OBS, a browser stream, a webcam app, anything works.

2. Run the program

python main.py

3. Choose your output

In the Output mode section, select:

• Restim — enter the WebSocket port (default 12346). Make sure Restim's WebSocket server is enabled under its settings.
• xToys — drives any toy connected in the xToys browser app. See xToys setup below.
• Windows Audio — click Refresh to list your output devices, then pick the one you want from the dropdown.
• MP3 Player — built-in player for stim audio files. Load a file and let the tracker drive the volume.

Set your Vol Floor and Vol Ceiling sliders to define the range the program is allowed to operate within.

xToys setup

1. Open xtoys.app in a browser and sign in
2. Go to Scripts → search for VisualStimEdger → Load Script
3. In the script's Controls view, open the Connections panel
4. Under GENERIC OUTPUT, add your toy (DG-Lab Both Channels, Lovense, etc.)
5. Under LOCAL WEBHOOK, make sure Local Webhook is enabled → Save
6. Click the ⚡ satellite icon on the Local Webhook card → Connect
7. Copy the Webhook ID shown (short string, e.g. 8hR5acKTCx2s)
8. Paste it into the Webhook ID field in VSE — the status bar will show xToys: OK

Note: The Webhook ID changes every time you reconnect in xToys. Re-copy it if you refresh the tab. Keep the xToys browser tab open while using VSE.

4. Draw a box around your video feed

A fullscreen overlay will appear. Click and drag to draw a rectangle around the window or region showing your camera feed, then release to lock it in.

5. Select the tracking point

A snapshot of your feed will open. Draw a box around what you want to track. Two good options:

• The head of your cock — works well if it's clearly visible and has decent contrast against the background.
• An electrode or ring on the head — usually better. The electrode tends to be a distinct colour or shape that the tracker can lock onto more reliably, especially as arousal changes the appearance of the skin.

Click Confirm when done.

6. Calibrate heights

With the program running and tracking, move through your states and click the buttons to record each position:

Button	When to press
Set Flaccid Height	When your cock is fully soft
Set Erect Height	When you're fully hard but comfortable
Set Edging Height	When you're at the edge

The program will then keep volume in a hold zone between erect and edging, reduce stimulus slowly if you push past the edging threshold, and increase it proportionally if you start to drop back toward flaccid.

Tips

• Lighting matters — consistent, even lighting gives the tracker the best chance of staying locked. Avoid backlighting.
• Electrode tracking is more reliable — skin tone and shape changes significantly with arousal; a silicone or metal electrode doesn't. If tracking keeps drifting, try selecting the electrode instead.
• If tracking is lost or jumps — the tracker freezes at the last known position (shown in orange) rather than snapping to something random. Use Re-Select Cock Head to relock onto the target.
• Re-Select Video Feed Area — use this if you move or resize the source window.
• Vol Floor — useful to make sure stimulus never cuts out completely. Set to 20–30% if you want a baseline.
• Vol Ceiling — caps how high the program will push volume. Set conservatively until you know how the session feels.

Troubleshooting

Restim shows Disconnected Make sure the WebSocket server is enabled in Restim settings and the port matches.

Tracking keeps jumping to my hand The tracker uses size and position plausibility filters to reject sudden jumps, but a hand close to the tracked area can still confuse it. Try to keep hands out of frame, or relock onto an electrode which has more distinct visual features.

No audio devices showing Click Refresh. If still empty, check that pycaw installed correctly (pip install pycaw). On Windows 11, audio device enumeration can fail due to permissions — try running the app as Administrator once to confirm this is the issue.
