I have had this book sat on my shelf for a while “Practical Arduino: Cool Projects for Open Source Hardware” this is an introduction to the Arduino Micro Controller; the use of its digital inputs and outputs makes it ideal for my kinky projects; weather that is detecting orgasms, or controlling fucking machines. now all i have to do is acquire a Arduino and start to play.
Reading the Document “8–13 Hz Fluctuations in Rectal Pressure Are an Objective Marker of Clitorally-Induced Orgasm in Women” it shows a graph of rectal pressure against Frequency; and Time:
As you can see there is a marked difference in pressure against time during Orgasm than during tasks. One way to sense this would be the use of a pressure sensor coupled with an inflatable butt plug.
In theory the but plug would be inserted into the young lady; inflated till it was under pressure; the valve would then be closed; the analogue value read from the Pressure Sensor as a zero point.
With a little bit of signal processing you could abuse the feedback to turn off other machines before or during orgasm; and also hopefully before…
Now to purchase a few sensors and try it out.
Here is a quick photo of my St Andrews Cross set up ready for use; Just need to now have chance to play 
Hopefully at the weekend.
From FetLife a Homemade dildo made for use with a Fucking Machine. It can be heated or cooled by circulating water through it. 2.25″ diameter. also has estim
May have to build something like this
Although I should stop looking at all the cool toys and thinking I should make that 
MoterFun.biz make a $390 – $430 USD camera they call the “DildoCam”; it seems very overpriced for a Bullet Camera; and four white LEDs encapsulated in heat shrink tubing.
If I was to make one; I would encapsulate the entire thing in a deep drilled polycarbonate/acrylic dildo. and I doubt that it would cost more than £125 ($170?).
One of the challenges facing good repetitive action toys, is the difficulty of making liner movement; the name of a device that makes liner movement is a “Liner Actuator” however they tend to be hard to come by as they are prohibitively expensive; require hydraulics, or pneumatics, either are very fast with little power; or very powerful but very slow; not to mention the thrust lengths can be far too short.
However on Buggies Built for Fun, Ian seems to have over come this with his simple Liner Actuator design; built using parts available from a cycle repair shop; you should be able to build an Actuator for about £150 (GBP).
I plan to try out Ian’s design on my Fucking Stool first and see how I get on.
One of those things that makes the rounds every so often is this:
According to this Brief History of Sex Toys:
“Developed by an American physician, George Taylor, M.D., it was a large, cumbersome, steam-powered apparatus. Taylor recommended it for treatment of an illness known at the time as “female hysteria.” Hysteria, from the Greek for “suffering uterus,” involved anxiety, irritability, sexual fantasies, “pelvic heaviness” and “excessive” vaginal lubrication — in other words, sexual arousal. However, since it was the Victorian era, women were not considered to be at all sexual and it was therefore deemed a disease. Physicians of that era treated hysteria by massaging sufferers’ vulvas until they experienced dramatic relief through “paroxysm” (orgasm). Unfortunately, hysteria was a recurrent condition and repeated treatment was often necessary. Taylor touted his steam-driven massage device as speeding treatment while reducing physician fatigue.”
It seems to be referenced in this document. it is an interesting device; but looking at the construction it is not the way I would have designed it.
One of those things that makes life easer is when everything works together:
“Vac-u-Lock has the unique ability to interchange between different dildos and penile extensions.
The patented plug is made of high impact ABS plastic and holds the systems attachments firmly, without any chance of accidental or slippage removal from the harness system.
The versatility and variety of available attachments is legendary. Fat, thin, long or short, whichever you and your lover fancy – Vaculock delivers!”
As Vac-u-lock gets everywhere it would be nice to be able to use it on my creations. However I am yet to find a Technical Drawing; or a sketch of the male part with dimensions. If any one has the parts and can quickly dimension it up for me, or when I get one I will be doing just that.
The Thought is; that I should be able to get them printed on a 3D printer.
About a year ago I came across this document “8–13 Hz Fluctuations in Rectal Pressure Are an Objective Marker of Clitorally-Induced Orgasm in Women”, and remember thinking that it could be an interesting thing to look into; especially when used in conjunction with a Fucking Machine (this FetLife thread).
Over on Fetlife I came across this post. which linked to this video:
Would you like to replay the video or share the link to it with your friends?
Well we all know Mordicus is more than a bit kinky, well I left her alone with the vid to have a shower; and I think that was a mistake…
Anyway with having some time on my hands; I got to thinking about how hard it would be to make one; and the answer is that it doesn’t look that hard so hopefully; once I get paid on Friday, I will be able to build a prototype pump, using parts from Amazon, and LEGO.
I have made a Bukkake Machine Page under Toys and Geekery for the Bukkake Machine; so as I build parts of it it and the Category should become a build log.
