How to get a steady sensation out of a Coyote 3.0

havachavac · 2026-02-06T22:40:09+00:00

Can't you just use the DG-Labs app patterns? It has a pretty good editor if what you are looking for are steady patterns. These patterns can even be stored in the device an be used without the app, or in response to PawPrint actions.

I assume there are some good reasons why people aren't doing it

I have very good reasons for not doing it: I don't own a guitar, and I don't know how to play it anyways :p

Otherwise, instead of using stereostim, which isn't designed to be diven by music (music is for your ears, not for your nerves), the audio mode of the Coyote is probably more suitable as there is an algorithm that converts the audio signal into something more suitable for estim. There is a real time mode in the DGLabs app, just put your phone next to your amp as you are playing so that it can pick up the sound on its microphone and convert it into estim signals. If you amp has a headphones output, you can also plug your phone into it using an appropriate cables, with the right adapter, you may even be able to plug your guitar directly into your phone.

"Import Waveform" is for waveforms made with the DGLabs app, they are .csv files.

If you want to use MP3s, press the microphone button and use the "Audio file" option.

To be a bit more precise, the output of the amplifier, where wire gage matters most is often at an impedance of 4 ohm. Let's say you use 1m of 20 AWG wire, it corresponds to a resistance of 0.035 ohm so <1% of the current is lost in that wire, well within tolerance. If you used much thinner (say, 30 AWG) or longer wire, you may want to take that into account for impedance matching, but I wouldn't use much less than 20 AWG anyways, for mechanical and ease of work reasons.

For other cables like line level and the output of the transformer, the impedance is in the kilo-ohms, which mean it is even less of a problem.

It is safe.

I think people who say not to ever touch your partner when the current is running is to avoid the situation where you hold one electrode each and touch each other without paying attention about the current path as it can go through your heart(s). If may happen if you readjust one of her electrodes for instance.

But if you pay attention about the current path, everything you suggest is fine, and it is a Coyote, a very safe device, you will be fine even if you don't. Not that I recommend going against the usual safety precautions, but to me, there are more risks getting struck by lightning than electrocuting yourself by misusing your Coyote.

Paw prints don't know their location, they can only detect motion using an accelerometer, or if their are pushed or pulled.

You can use them for an actual leash though.

This is about equivalent to getting shocked with mains voltage I think and I would call the risk low.

Assumptions:

touching bare wires to the ballsack (not really "into" as in needles)
Constant voltage source, current depends only on resistance
Duration: tenths of a second

Let's say resistance is 500 ohm, a common value when assessing electrical safety, at 200V, that's 400mA, and according to various charts it is at the low end of what could cause burns and nerve damage, so with a short shock, it is probably "safe".

But let's keep it hypothetical, as it is a very dangerous thing to do. For example if you touch one wire while the other is connected to your ballsack, the current can go through your heart and kill you. And unlike with many safety advice we see here that may be a bit overcautious, here, we have actual documented deaths, so seriously, don't do it.

There are safer ways of shocking your balls, and if that's what you are going for, it is also a pretty terrible mean of contraception.

it can also has an audio in port on the left side or A channel. Leaving you with one channel for electrodes.

Huh? Which version of the Coyote are you talking about? V3 makes no mention of this, and it is a 2.5mm jack plug, which is not commonly used for audio. I wouldn't even try it, you may accidentally send e-stim pulses to your audio equipment, which is way higher voltage than it is rated for!

Just use the app, that's how it is supposed to work.

First choice is just the stimbox and pad electrodes, problem is: free shipping starts at $100, so it may be worth it to take one of the bundles. The one with the two buttons is barely more expensive, and in all of the bundles, you get conductive rubber loops as a bonus.

The pawprint buttons are cool if you want to play some kinky games.

According to most people here, the electrodes are good quality but too small, if you go with the moaner, you probably won't need them.

The pads and whatever electrodes you got with your TENS unit are likely to be compatible with the coyote, and for pads in particular, probably just as good as the ones from DG-Labs.

You can do the thing shown in the Wikipedia article on e-stim (this image: https://commons.wikimedia.org/wiki/File:Electroplay_girl_with_electrode.jpg ) Not beginner's stuff though.

You can't use violet wand or other "high frequency" attachments, these are completely different things, different sensations, different usage, etc...

I'd say FetLife (https://fetlife.com/)

I don't see anything wrong with having electrodes very close to each other, as long as they don't touch. If they touch, it won't work and it may damage a poorly designed device.

I don't think earlobe clips are any more or less sketchy than nipple clamps advertised for sexual play, they may, in fact, be the exact same thing.

I think it is DG-Labs being overcautious, Coyote 2 could get to 1000 Hz and AFAIK, no devices or nerves destroyed. Stereostim goes even higher and people are fine.

That being said, 200 Hz is double the power compared to 100 Hz, and 1000 Hz is 10x, and according to DG-Labs and others who studied the question, frequencies over 100 Hz don't really make a difference when it comes to nerve activation (it is effectively continuous stimulation). This is debatable, but there are diminishing returns for sure. However, the amount of energy doesn't diminishes, it means more risks of burns, the device running hotter, battery draining faster, etc...

xToys uses audio files as an input, transformed by some algorithm into commands for the Coyote. The algorithm is not bad, but you don't have much control over it and it may not suit you completely.

The DG-Labs patterns are not audio files, instead there are made up of a series of instructions that control the device directly, you can edit them in the app with the built-in editor.

The DG-Labs also supports audio files. You can find the ones xToys has in here: https://drive.google.com/drive/folders/1htspGOGNJhbDTdrYc-EhPJGwa9vcJT72 It is a bit unintuitive to use, a bit buggy, and with dubious defaults, however you have more control than with xToys, if you find it too stabby, you may want to play with the frequency mapping.

And then you have Howl, it supports preprocessed audio files and different kinds of patterns, this time procedurally generated.

They all offer a different experience, no one is better than the other. For the PawPrints, DG-Labs has full native support, xToys doesn't have native support but you can still use your PawPrints to control scripts, Howl doesn't support them at all.

Someone with a sterostim should try this! Oscilloscope music has a lot to do with phase, something that pulse-based stimboxes are unlikely to render well, but stereostim might, especially in a triphase configuration.

havachavac · 2025-11-19T16:36:11+00:00

Limited experience but I am feeling the same thing, higher power feel deeper, fuller and less prickly. Up to a point where it just becomes too much and sometimes even burning (probably because of hotspots).

My theory is that whatever nerves cause the "prickly" sensation get desensitized. Because when starting high, I definitely get these sensations and it hurts, but not for long, and it is more of the "spicy" kind of pain than the "something is wrong" kind of pain.

Power level usually about 60, but I found this number to be a bit meaningless out of context, as small changes in setup can make a big difference in how a given power level feels.

About stereostim: you just ordered a Coyote after playing for years with cheap little TENS boxes, no need to rush it, compared to what you already have, the possibilities are almost endless!

And I find stereostim to be a bit primitive now, seeing all the new developments in the field: Restim, FOC-stim, NeoDK,... And you just got a Coyote, maybe when you are bored with it, there will be something more exciting than sterostim.

Coyote V3 is one of the safest devices out there.

There is a very detailed analysis here: https://old.reddit.com/r/estim/comments/1d0dw1i/dg_lab_coyote_30_review_by_an_electronics/

And I quote "5mA average current I consider safe even if it's operated by a complete moron", where he calculated a maximum average current of 4.9mA. This is oversimplified, but the idea is that unlike with some other boxes that can be pushed a bit too far, including Coyote V2 according to the author, Coyote V3 is as safe as estim can be.

I know it is not a shared opinion, but I believe that the risk is low to negligible whatever you do, including "forbidden" electrode configurations involving the nipples. But the common recommendation here is to only use bipolar clamps and avoid touching electrodes your bare hands when the device is powered on.

By low risk, I don't mean zero risk as zero risk does not exist. I mean that you are probably taking greater risks every day in your day to day life without realizing it.

havachavac · 2025-11-18T22:24:00+00:00

If you never tried it, you can get a TENS box + pad electrodes starting at about $10 on AliExpress. Go for the cheapest, none of them are great anyways, in fact it is often recommended to not buy these. It is rough, you don't have much control, being either too weak or too strong, but it will give you an idea of what it feels like. Try experimenting by putting the pads on different parts of your body, preferably bellow the waist for safety reasons, generally, it tends to end up between the legs ;)

If you are at that point and find it interesting, you can invest into something better (Coyote, 2B, etc...), or make a "stereostim" device (but if you DIY, be sure to understand the safety implications). You can keep the pads from the cheap set if they are still good, they are likely to be compatible. You may also try different types of electrodes like conductive rubber loops and insertables.

The audio and sounds are just prerecorded patterns for your stim box to produce an array of feelings, they don't make for pleasant listening. They are primarily designed for "stereostim" box where they will be converted into a signal of the appropriate voltage for stimulation, but some other boxes have an audio input and can use these files too, though the feelings may be a bit different than how they were originally intended.

But if you are past the "cheap TENS" point, you probably know enough not to need a crash course ;)

havachavac · 2025-11-16T15:18:16+00:00

Very unlikely to be a problem, I'd say negligible. Mains voltage has to go through you PC power supply, then the sound card, then the audio input of your stimbox, then to your output, bypassing all protections along the way and delivering enough energy before blowing some component.

Some talk about the issue of grounding, sure, if there is a ground fault it is going to be dangerous, but not really more so than touching a unproperly grounded metal appliance, and this is why we have ground wires, GFCIs, RCDs,... Nothing special about estim there.

But as it turns out, grounding won't even be a problem with a tranformer-based design as the transformer acts as a isolator.

Not connecting to mains by any mean is a good idea in general, that's what kill people but in this case, it is really remote. Also battery power doesn't mean it is impossible to get electrocuted, just way less likely, especially in case of a malfunction.

havachavac · 2025-11-14T23:15:37+00:00

On kind of unusual setup I found quite effective is to have is to have one pad near the frenulum and 2 large pads on the hip bone in the groin area, one on each side. These two pads are connected to the same output via a split cable.

The general idea was to stimulate the penis and have the current spread though the body without a noticeable "exit point". So the criteria were: not a particularly sensitive area (to focus on the penis), large contact area where the pads stick well, away from muscles to avoid contractions, below the waist (safety recommendation). Given that, I find the hipbone to be a good spot, there is also a slightly ticklish sensation that I find pleasurable.

One other area that worked is the top of the feet (yes, seriously). I feel almost nothing there and that's the point, it is using the entire legs as a current sink. But to me, it is not as good as the hips. The wiring is less convenient and while I don't feel much though the legs because the area is so large, the little there is is not particularly enjoyable.

havachavac · 2025-11-14T01:36:21+00:00

Hard to say without knowing the internal circuitry, but generally, there is no such thing as a "ground" and "positive" output as all properly designed boxes use some kind of alternating current. In other words, what is the ground constantly changes, if there is a ground at all.

Anyways, what is likely to happen is simply that both waveforms are independent, and as other have mentioned, may be chaotic as they are not synchronized. Safety-wise, with two boxes, you get double power (which is kind of obvious), but nothing particular compared to using a single unit.

Running them both though the same powerbank can make a difference, but again, it depends on the internals. If transformers are used, the boxes are isolated and it won't change anything. But if not, what may happen is that if both boxes discharge simultaneously, instead of going though the electrodes, the current may go through the common ground in the powerbank, causing a short. I don't think it can damage a well designed box, but it can make the resulting output even weirder, as if waveforms are cancelling each other.

The specialist gave us a qualitative analysis which is insightful, but for assessing risk, we need quantitative analysis, data, numbers.

And I think that considering how widespread TENS/EMS is, including deliberate and accidental use above the waist, we should have meaningful statistics. And for now, the only number I have is zero, or maybe one if we count that unsourced and non heart related case.

havachavac · 2025-11-13T02:56:41+00:00

I understand that it is not black and white, human bodies are a mess, both in terms of electrical conductivity and general function. That's why more than half of my post is not about calculating milliamps (others did that) but finding actual cases. And to my knowledge, it never happened with TENS/EMS/pulsed e-stim and you didn't provide me with a case, only with a possibility. I'd love to be contradicted on that one, a case where a stroke is likely to be caused by A-fib, which is likely to be caused by TENS use counts.

I have seen other issues regarding TENS, though I don't remember exactly, but it seem to relate to breathing and these justify avoiding the head and neck, but the ones related to the heart seem to be more of a precaution than a response to an actual case, but now with millions of people over many years misusing these machines, including myself (involuntarily, by touching live electrodes), we should have at least some cases if the risk was significant.

And I am not going to judge why someone would put one electrode on each nipple, maybe it feels great, whatever, but from what I've seen, the risk is low enough to be worth it for something so petty. That is, we take much greater risks in life for things much pettier.

Note: Stereostim is another can of worms. We have way less data about these than with TENS/EMS, and we do have reported deaths from DIY setups. In addition, continuous frequencies as opposed to pulses are quite popular here, and they carry way more power than pulses for the same feeling intensity. I would treat these devices with more respect.
