Update #3 on the sex toy you can feel

A while ago, I had an idea on how to create a strapon that the wearer can actually feel, as though it were part of your body. The idea took off, so I started a company and commissioned an engineering firm to do a design proposal. I recently tested a first-generation prototype, and discovered that not only does the tech work, it works far better than we expected.

Things have gone a bit crazy since then. I’ve received an avalanche of support and interest, and I’ve been talking to folks from all over the place who want to see this device become a reality.

I’m working on a second generation prototype that’s a lot more sophisticated than the first-generation prototype. It’s an interesting bit of engineering, for sure.

Still quite crude, but I’m refining it very rapidly. Right now, the main area I’m concentrating on is sensor design. The second prototype will have much more sophisticated sensors and will actually be usable for fucking (the first prototype wasn’t really suitable for penetration).

We’ve also been doing tons of market research, and the results have helped steer us toward a design that will work well for a lot of people.

Update #2 on the sex toy you can feel

A while ago, I had an idea on how to create a strapon that you can actually feel, as though it were part of your body. The idea went crazy, a lot of people expressed overwhelming support, so I started a company and commissioned an engineering firm to do a design proposal.

In the meantime, I’ve also been working on the idea independently of the engineering firm, so last week I put on my Mad Scientist hat1 and built a simple proof of concept.

Then I went to my friend Emily and said “hey, I have this prototype of a computerized strapon with sensors and a wearable computer and stuff, do you want to help me test it?”

“Sure!” she said, because my friends rock. (I love my life.)

So two days ago, I showed up at her house bearing the crude prototype. “Okay,” I said when we were safely in her bedroom, “this bit goes here, and that bit goes up in front like so…”

There were some design flaws in the first version–the wires leading from the computer to the electrode weren’t quiiiiiite long enough, so she ended up doing this one-legged dance trying to put it on. When it was all powered up and running (which looked quite odd–the sensors mounted to the big purple dildo all have little red lights that come on to show the sensor is working, so the overall effect looked a bit like a prop from a 70s science fiction porn flick), we spent some time adjusting the signal generator and making sure everything was working, and then got to it. I touched the sensors and had her describe what she felt. At one point, as I knelt in front of her stroking her cock, it suddenly struck me exactly what I was doing. “Man,” I said, looking up at her, “this is really obscene.”

“But Franklin,” I hear you ask, “how did it work?”

Emily wrote a really good writeup from her perspective on her blog, appropriately titled “Brains, Bunnies and Boners.” Here’s an excerpt:

I stood sporting a sizable electrode-covered, purple erection as this man knelt before me stroking the blinking phallus. Looking dreamily into space, I concentrated on this new sensation and how to communicate it. He asked questions that had nothing to do with arousal and everything to do with programming or nerve density. It crossed my mind briefly that this was a strange situation. Covered in wires, half naked in front of a man I’m not intimately connected to, waxing poetically about the sensation of him passively stimulating my g-spot. Meanwhile he educates me on the corresponding connections between penis and vagina, sensitivity wise. […]

I see him touching the wirey and weird strap on, the sensation of that cock hitting my pubic bone becoming enough to fully trick my mind. The arousal of the plug flitting electrical currents over my internal nerves quickly translates into a thought of, “wow if he keeps doing that I’m going to get a hard on during science and that will be embarrassing.” Except logically I know I already have a hard on. A big purple one that he brought along for me to borrow. My brain has already made the adjustment in the five minutes we’ve been testing this to believing in the new genitals.

So the answer is it works really, really well. Far better than I expected, given how primitive the prototype was. Within minutes, it seemed her brain had internalized the dildo as part of her body; she said that touching the dildo felt like touching her. Which was amazing. I’d expected just to validate that the device could be made to work; I didn’t expect it to work that well.

I am actively pursuing making this device a reality. We’re currently enrolled in a venture accelerator program in Vancouver and we’re doing market research to validate the market for this device. Interested in being interviewed as part of that market research! Hit me up in email! franklin (at) franklinveaux (dot) com.

Sharks and Loathing in Las Vegas

I am a man who wears bunny ears.

As I write this, I am on the last leg of the book tour–six events over the next four days and I am finally done. Part of the tour took me through Las Vegas. And Vegas…Vegas is not what I expected.

Close your eyes. Imagine Las Vegas, that epicenter of sin and decadence in the desert. What do you picture? Giant neons. Slot machines. Organized crime. Women in huge feather headdresses. Not, you might think, the sort of place where a man in bunny ears would exactly stand out…

…and you’d be wrong.

Vegas is, it seems, not prepared for a man in bunny ears, oh no. The hostility with which the Las Vegas culture1 responds to the sudden appearance of a man in bunny ears in its collective midst is remarkable.

But let me backtrack for a moment.

As I have traveled the country talking about polyamory and ethics and such, I’ve brought a stuffed shark with us. The shark, who joined our team2 in Atlanta, has made appearances all over North America, solely for the purpose of being exploited.

It started as a lark, you see. There is person is a marine biologist who studies sharks. He also writes angry blog entries in response to phony stories on the Discovery Channel, stories with lurid titles about how mermaids might be real (spoiler: they aren’t) and speculating whether Megalodon, the enormous prehistoric dinosaur-shark, might still be alive (hint: it isn’t).

There are trolls on the Internet, and some of these trolls want to believe in mermaids and Megalodon. So they follow this person about online, posting pictures of him and diatribes about him with the Twitter hashtag “#nerdsexploitingsharks“.

Which is, thought I, absolutely begging for hijacking.

So, half an hour before I was scheduled to do a lecture in Atlanta, I darted out in frantic search of a stuffed shark to exploit. I found one at the Atlanta Aquarium, and it’s been accompanying us ever since, being photographed in exploitative situations and posted to social media under #nerdsexploitingsharks.

So. Back to Las Vegas.

Las Vegas doesn’t like a man in bunny ears. Las Vegas especially doesn’t like a man in bunny ears carrying a stuffed shark.

Now, there are many ways to carry a stuffed shark. If you ever find yourself in Las Vegas wearing bunny ears and carrying a stuffed shark, you might try one or more of these carry techniques. I present this information in the name of Science!3


The Security Blanket

An attitude that says “Yes, I have a stuffed shark, and what of it? I need my shark if I am to face a cold, cruel world.” Advantages: Few people will approach a person who uses a shark as a security blanket. Disadvantages: Few people will approach a person who uses a shark as a security blanket.


The ‘Shark? What shark?’

Who, me? I’m not carrying a stuffed shark! Oh, this? How did this get there? Advantages: From the front, you simply look like a man in bunny ears, not a man in bunny ears with a stuffed shark. Disadvantages: Las Vegas loves guns. The sight of a man in bunny ears with his hands out of sight might upset some folks with delicate sensibilities, and some of those folks with delicate sensibilities might be armed.


The Casual Carry

This technique challenges the observer: “Yeah, I’m carrying a stuffed shark, and how do you like THEM apples?” Advantages: People might assume you’re a famous performer, or, failing that, an eccentric Mob hitman with a pistol inside the shark like that one scene in Hudson Hawk, only with a shark instead of a teddy bear. Disadvantages: People might assume you’re barking mad.


The en garde!

Yeah, I have bunny ears. And a shark. Which might or might not contain a concealed pistol. Don’t fuck with me. Advantages: People give you a wide berth on the sidewalk. Disadvantages: You might get shot.


The Binky

Similar to the Security Blanket, but less neurotic, the Binky tells the world that, yes, the world is cold and cruel, and yes, your shark helps you navigate the rivers of cruelty all around you, but you don’t really need the shark. You just like the shark, okay? Advantages: More relaxed and casual than the Security Blanket; this attitude tells the world you really can stand on your own two feet. You know, if you want to. Disadvantages: Small children point at you.


The Bromance

“I love you, man!” This attitude tells the world you and your shark have a special friendship…but, like, totally in a heterosexual way. Advantages: It’s totally, like, a heterosexual thing. Not, like, that other thing. Disadvantages: You may be mistaken for a dudebro. Who wears bunny ears. And carries a stuffed shark.


The Two-Handed Casual

“I’m just carrying a stuffed shark from one place to another place. Nothing to see here. Move along.” Advantages: Very workmanlike. People won’t get the impression that you’re, y’know, attached to the shark or anything. Disadvantages: It’s still pretty weird to see a guy in bunny ears carrying a stuffed shark, no matter how workmanlike he may be. Plus you don’t have a hand free to drink alcohol, play slots, and convince yourself that this thing you’re having is fun.


The Secure in my Masculinity

This pose shows the world that you’re absolutely certain of your manhood and you’re not too threatened to express your true feelings, even if you happen to be in the middle of one of the world’s largest casinos. Advantages: People will stay far, far away from you. Disadvantages: Unless they’re security.


1 Insofar as Las Vegas can be said to have a “culture.” My observations of Las Vegas culture suggests it is made up primarily of people who have no idea how to have fun desperately trying to have fun and convincing themselves the thing they are having is, indeed, fun. And alcohol.

2 Was purchased and exploited.

3 I am frequently asked “are you a scientist?” I usually say “no.” I think I am probably going to have to start saying “yes,” so when people ask “what kind of scientist? Chemist? Biologist?” I can say “Mad.”

Sex tech: Update on the dildo you can feel

A few months back, I wrote a blog post about a brain hack that might create a dildo the wearer can actually feel. The idea came to me in the shower. I’d been thinking about the brain’s plasticity, and about how it might be possible to trick the brain into internalizing a somatosensory perception that a strap-on dildo is a real part of the body, by using sensors along the dildo connected to tiny electrical stimulation pads worn inside the vagina.

It’s an interesting idea, I think. So I blogged about it. I didn’t expect the response I got.

I’ve received a bunch of emails about it, and had a bunch of people tell me “OMG this is the most amazing thing ever! Make it happen!”

So I have, between work on getting the book More Than Two out the door and preparing for the book tour, been chugging away at this idea. Here’s an update:

1. I’ve filed for a patent on the idea. I’ve received confirmation that the application has been accepted and the process is started.

2. I’ve talked to an electronics prototyping firm about developing a prototype. Based on feedback from the prototyping firm, I’ve modified the initial design extensively. The first version I’d thought about was based on the same principle as the Feeldoe; the redesign uses a separate dildo and harness, with an external computer to receive signals from the sensors in the dildo and transmit them to the vaginal insert. The new design looks, and works, something like this. (Apologies for the horrible animated GIF; art isn’t really my specialty.)

3. The prototyping firm has outlined a multi-step process to develop a workable, manufacturable device. The process would go something like:

Phase 1: Research and proof of concept. This would include researching designs for the sensors on the dildo and the electrodes on the vaginal insert. It would also include a crude proof-of-concept device that would essentially be nothing more than the vaginal insert connected to a computer programmed to simulate the rest of the device.

The intent at this stage is to see if the idea is even workable. What kind of electrodes could be used? Would the produce the right kind of stimulation? How densely arranged could they be? How small could they be? Would the brain actually be able to interpret sensations produced by the electrodes in a way that would trick the wearer into thinking the dildo was a part of the body? If so, how long would that somatosensory rewiring take?

Phase 2: Assuming the initial research showed the idea to be viable, the next step would be to figure out a sensor design, fabricate a microcontroller to connect the sensors to the electrodes, and experiment with sensor design and fabrication. Would a single sensor provide adequate range of tactile feedback, or would it be necessary to multiplex several sensors (some designed to respond to light touch, others to a heavier touch) together in order to provide a good dynamic range? What mechanical properties would the sensors need to have? How would they be built? (We talked about several potential designs, including piezoelectric, resistive polymer, and fluid-filled devices.) How would the sensors be placed along the dildo?

Phase 3: Once a working prototype is developed, the next step is detail design and engineering. This is essentially the process of taking a working prototype and producing a manufacturable product from it. This includes everything from engineering drawings for fabrication to choosing materials to developing the final version of the software.

So. That’s where the project is right now.

The up side? I think this thing could actually work. The down side? It’s going to be expensive.

I have already started investigating ways to make it happen. If we incorporate in Canada, we may be eligible for Canadian financial incentives designed to spur tech research and development.

The fabricating company seems to think the first phase would most likely cost somewhere around $5,000-10,000. Depending on what’s learned during that phase, the development of a fully functional prototype might run anywhere from $50,000 to $100,000, a lot of which hinges on design of the sensors, which will likely be the most challenging bit of engineering. They didn’t even want to speculate about the cost of going from working prototype to manufacturable product; too many unknowns.

I’m discussing the possibility of doing crowdfunding to get from phase 2 to 3, and possibly from phase 1 to 2. It’s not likely that crowdfunding is appropriate for the first phase, because I won’t have anything tangible to offer backers. Indeed, it’s possible that I might spend the initial money and discover the idea isn’t workable.

Ideally, I’d like to find people who think this idea is worth investigating who can afford to invest in the first phase. If you know anybody who might be interested in this project, let me know!

Also, one of the people at the prototyping company suggested the name “Hapdick.” I’m still not sure how I feel about that, but I do have to admit it’s clever.

Sex Tech: Adopting the Brain’s Plasticity

Some while ago, I read an article about a gizmo made of a black and white video camera attached to a grid of electrodes. The idea is that you wear the electrodes on your tongue. Images from the video camera are converted into patterns of electric signals on the electrode, so you “see”–with your tongue–what the camera sees.

Early users of the prototype gizmo would wear a blindfold and then try to navigate around just by the electrical impulses on their tongues. What’s most interesting is not only were they able to do this, but they reported that, after a while, their memories were not of sensations on their tongues, but of seeing a fuzzy, black and white image.

The brain is wonderfully plastic, able to interpret new kinds of sensory input in amazing ways. It can rewire itself to accommodate the new input; in fact, the tongue-electrode thing is being commercialized as a device for the blind.

As I do, when i first heard about this, I naturally thought “how can this be used for sex?” And I think it has fantastic potential.


Imagine, if you will, a wearable dildo, rather like the Feeldoe, that’s designed to have one end inserted in the vagina. Only imagine that we take the same kind of electrodes used in the tongue-camera device, and send signals to the electrodes not from a video camera, but from small touch sensitive sensors mounted just below the skin of the dildo.

These sensors would be mapped onto the electrodes so that when something touches the sensor, you’d feel a corresponding signal from the corresponding electrode.

I’m not an artist, but I made a couple of crude animations to illustrate the idea:

What would happen?

I believe that after a period of adjustment, this dildo would be incorporated into the brain’s somatosensory perception. The brain would, in essence, modify its model of the body to accommodate the dildo–it would, rather quickly I suspect, cease to be perceived as a thing and become perceived as a part of the body. Stimulation of the dildo would begin to feel like stimulation of yourself.

And isn’t that an interesting idea.

The neural density in the walls of the vagina isn’t as great as the neural density of the tongue. I don’t think that’s a problem, though; the neural density of the shaft of the penis isn’t as great, either.

One potentially interesting twist on this notion is to map the most sensitive part of the penis, the underside just below the glans, onto the most sensitive part of the body–the clitoris. The sensors of the shaft would map onto electrodes in the bulb worn inside the vagina, except this part, which would map onto the clitoris–mapping the sensitivity of a natural penis.

Another potentially interesting thing to do is to make the sensors on the dildo pressure sensitive, with firmer touches creating stronger impulses from the electrodes.

Now, there’s a lot of experimentation between this idea and a real device. I don’t know the neural density in the walls of the vagina, but it would impose a limit on how many electrodes could be placed on the dildo. Would there be sufficient density to be able to create a fine tactile sense? I think the answer is probably “yes,” but I’m not sure.

I’m also not sure how much processing would be required. I’m guessing not much; certainly much less than is required with the vision sense. The tongue-vision thing is trying to do something far more complicated; it’s trying to register sufficient information to allow you to navigate a three-dimensional world. A circle seen by the camera might be a lollipop right in front of your face or a billboard far away; because the tongue has no way to represent stereo imagery, there’s no way to tell. So the processor has to allow the operator to be able to zoom in and out, to give the user a sense of how far away things might be. It has to be able to adjust to different lighting conditions.

The dildo, by way of contrast, merely has to respond to physical touch, which maps much more easily onto the array of electrodes. It’s pretty straightforward; if something’s not touching a particular sensor, its electrode isn’t producing a signal. The amount of processing might be low enough to allow the processor to be housed inside the dildo, making the device compact, and not requiring it to be tethered to any electronics.

I think this thing could be hella fun. It would allow people born with vaginas to have a remarkably good impression of what it’s like to be born with a penis.

In a world where I had infinite free time, I’d put together a crowdfunding campaign to try to build a working prototype. Even without infinite time, I’m considering doing this. Thoughts? Opinions?

Sex for Science! Epilogue

Sex for Science! Chapter 0
Sex for Science! Chapter 1
Sex for Science! Interlude
Sex for Science! Chapter 2
Sex for Science! Chapter 3
Sex for Science! Chapter 4

Last weekend was edwardmartiniii‘s birthday. Entirely on his own, with no input from me, he chose a theme for the party: a Mad Science Fair. Kind of like the science fairs that grade schools and high schools have, you see, only with significantly more insanity.

Regular readers of this blog are no doubt familiar with the ongoing saga of my quest to make a cheap, homebrew, thought-controlled sex toy.

I’m actually working on two projects in tandem: the Tormentor, a sex toy designed not to allow the wearer to reach orgasm, and a sex toy that is controlled by the wearer’s thoughts. I’ve been making significant progress on both fronts in the past few weeks, with prototypes for both a thought-controlled vibrator and the third-generation Tormenter now complete.

And, thought I, what better Mad Science Fair project than the thought-controlled toy?

I put together a display detailing the experiments to date, most of which took place in an especially seedy motel room in Seattle; you are, I’m sure, all no doubt familiar with that tale by now. I also loaded up new beta-test software into the modified EEG, this time intended not just to record a person’s brainwaves, but also to switch a vibrator on and off in response to them. This suitably equipped, we (zaiah and I) set out to the party, with the lovely shadow-5tails in tow.

The party proved fertile ground for test subjects, with a number of party-goers volunteering to have their brainwaves analyzed as they tried to switch a small egg vibrator on and off. (I have, it must be said, totally awesome friends; they give the best data!)

And, interestingly, more than half the people who volunteered to give the gizmo a whirl were able to make the vibrator switch on and off, even in noisy, crowded surroundings that made concentration difficult. Several people were able, with less than ten minutes’ practice, to switch the vibrator on and off at will, simply by thinking about it.

Which is hella cool, if you ask me.

I’ve put up a PDF of the display for the Mad Science Fair, “Analysis of the Practicality of Detecting Physiological Signals of Arousal in Adult Human Brains with Practical Applications of Brainwave-Controlled Stimulation Via Neurofeedback Control and Regulation of Vibratory Devices: A Hands-On Investigatory Approach,” which those of you who might find this particular flavor of mad science interesting can read at your leisure. Eventually, I plan to provide a detailed report of the equipment, software, and test results of the thought-controlled vibrator itself. Stay tuned!

Review: Kinklabs Neon Wand

Back when I was married and living in Tampa, one of my favorite sex toys in the sex toy drawer box closet was a violet wand. It’s a gadget that you plug glass electrodes into and then plug into the wall. When you turn it on, it makes a buzzing noise and the glass electrodes turn purple, and then when you touch someone with the electrodes you get a sensation that’s like…

Well, it’s kinda hard to describe what it’s like. A lot of folks (like me!) who don’t like electrical play still like violet wands, because they don’t really feel like electric shocks. It’s more like little teensy hot needles caressing your skin. There are lots of different shapes of electrodes, that all make different sensations, but that’s the basic theme.

They’re amazing toys. They’re also very spendy. The violet wand I used to have cost me about $700, so when I lost it, I couldn’t afford to replace it, and I’ve been missing it ever since.

Recently, JT’s Stockroom sent me a neon wand as part of a promotion. And, to be honest, I’ve been waiting for someone to realize the market for cheap, reliable violet wands for rather a long time.


This is the Kinklab Neon Wand. If you really want to get technical, it’s not a violet wand, though the reasons that’s true are largely academic.

But, since this journal has never been afraid to venture forth into the academic, I’ll explain why; click here if if you’re interested.

Another podcast interview!

A couple weeks back, I had the opportunity to meet Shira B. Katz of the Pedestrian Polyamory podcast. What followed was a conversation about polyamory, transhumanism, mad science, programmable sex toys, and all sorts of other stuff, which you can listen to here.

The interview was great fun. I’d definitely love to do it again.

More on the Mathematics of Sex Toys

I’ve been posting a bit about the Tormentor, a sex toy I’m designing for the sole and nefarious purpose of not letting the user get off. Quick recap in case you haven’t seen the project so far: it’s a vibrator connected to a programmable microcontroller that’s programmed to run the vibrator in random patterns for random lengths of time with random pauses in between, to keep the wearer sexually aroused but without being q-u-i-t-e enough to allow the wearer to come.

Because, yeah, I’m kind of a bastard.

My sweetie lapis_lazuli beta tested the first standalone prototype, the Tormentor version 0.2, and the biggest problem that arose was that the deice was just too damn bulky.

Part of this was the fault of using a 9V battery to run the microcontroller, but part of t was the fact that the Arduino Uno board I’m using is just plain big.

I mentioned this problem to roadknight last time I was in San Francisco, seeing how he’s also a micorocontroller hacker and general mad scientist. He suggested that I use a Teensy USB board in place of the Arduino, and even gave me a spare that he happened to have handy.

The name doesn’t lie.


Size comparison, top to bottom: 9-week-old Tonkinese kitten, Arduino Uno, Teensy USB

The Teensy is certainly that; it was the second-smallest programmable microcontroller in his collection. (The first was an obscure Chinese something something on a flexible board, about the height of a grain of rice and three times that long.)

I’ve started looking into building the Tormentor version 0.3 around a Teensy. It’ll take a bit of work; the Teensy lacks an on-board voltage regulator, for instance. I’m thinking of using a 6.3v lithium battery to drive both the Teensy and the sex toy; I’ll have to cobble together a recharge/regulator circuit of some sort, but it should let me get the finished gadget very, very small indeed.

The Teensy people don’t understand something that Apple does: User experience matters. The Teensy board is unlikely ever to knock over the Arduino as the reigning champ of DIY microcontrollers, even though the Teensy is smaller and has better technical specifications, because the user experience when it comes to programming a Teensy is, to put it bluntly, abysmal.

You don’t get no Arduino-style all-in-one IDE and device programmer, where you can type code into a window and press a button and bam! The device is working! Oh, no. The Teensy requires you to install a gcc compiler, then type your code in a text editor, run it through gcc with make, and then load the resulting hex file onto the board with a loader program. It’s archaic and barbaric, and it brings back memories of my Programming 101 class in college, in which I wrote 8080 assembly on a CDC Cyber 760 mainframe, compiled it to a hax hex file, copied it onto a floppy disk, then ran it on a CP/M machine using a hex loader.

Someone, please kill me now.

There is, though, an Arduino IDE plugin for the Teensy, and though it’s a bit weird and doesn’t run all Arduino code, it looks like it should work for me.

The Mathematics of Sex Toys Made Tangible

A while back, I posted a picture of a very early prototype sex toy designed to prevent its wearer from getting off.

This project is entirely separate from, and shouldn’t be confused with, the prototype sex toy that’s operated by the wearer’s brainwaves, which I’m still working on. The sex toy that is designed to keep the wearer from getting off, which I’ve started calling the “Tormentor,” is a vibrator connected to a programmable controller board that’s set up to run at random intervals with random pauses in between–perfect, in other words, for keeping whoever’s wearing it always aware of it, while not letting that person get enough stimulation to reach orgasm.

The very first proof-of-concept version was basically a bare controller board tethered to a laptop and connected to a vibrating egg. As it wasn’t exactly portable, it wasn’t able to do what I wanted, which is to be worn around while shopping or doing housework or otherwise going about one’s business.

So I started working on getting a more portable, self-contained version set up and running.
