Fool_4's automatic PE device

I still think you’d have been better looking into the use of microcurrents while holding the tissue under tension via vacuum or extender.

I’m still impressed by and interested in your engineering skills though, I wish I was so mechanically able.

I was just thinking to myself, this could be practical, in that men pay tens of thousands of dollars if not hundreds of thousands for a Ferrari when they feel the need to “compensate”, what might someone pay to NOT HAVE TO?

Just a thought.

PS I am not doing this for gain, well not in the pocketbook anyways.

Capernicus, I have not taken electro stimulation out of the ultimate goal, not by a long shot. Electro if nothing else will be used to mitigate discomfort.

I see a shortcoming, in that this device will never be able to deliver the BTC pull angle so often cited on this forum. Well I guess it “could”, can you say 6 AXIS robot? Anyone have an old Motoman in their closet they wanna part with?

Please excuse the length of time it has taken me to add my two cents again. What you are proposing is very complex and requires a lot of reflection on my part before I feel I can contribute in a positive way. Also, your brain works faster than mine and when I get back to post my thoughts I see five more posts to consider. I will try to address them all from my last post on.

First off about the ultrasonics. I know they use ultrasonic technology in the beauty industry but again the units are hand held and are constantly moved over the surface of the skin so as not to build focus on one spot. I am not saying don’t use ultrasonic technology. Just to be careful if you are going to use it. You only got one dick (I imagine) and I would hate to see you risk localized internal soft tissue heat damage/coagulation simply because of an oversight. I still feel from a standpoint of safety IR heat is best although I am not sure how practical it would be to use in your application. The upside of IR heat is that it is a “no brainer” in that its deep tissue heat is effective and safe with no “pitfalls” that I can think of.

Absolutely love your flight case with the nuclear warning stickers and all by the way.

I also want to say don’t think you are alone and there is no interest in what you are doing. I think there is great interest in what you are doing and plenty of it. It’s just that what you are doing is very complex and even with my engineering background feel a bit “in over my head” in trying to comment on the technical aspects. I really have to think hard about this and that is why it takes me so long to reply.

I think the idea for a juction box with a main umbilical is the way to go if you don’t want a spaghetti nightmare. You’ll save a lot of future frustration tracking cords down. Wish the other technical aspects were as easy to weigh in on - hahaha.

I am assuming you want to use microcurrent technology to speed healing and promote tissue growth. Unfortunately, what I know about that you can put in a thimble and have room for a cup of coffee. So if there are any pitfalls I can’t give you a heads up there.

As far as the Ferarri people go, I truly think gain in inches and in bank account is not a bad thing. In fact gain in the bank account department would allow you more freedom in your R&D work. Usually a project of this magnitude is backed by a corporation and numerous engineers with the bank account to keep it going. If you get this off the ground that is really saying something.

As far as the “shortcoming” of the BCT angles goes I can only say this. I have never seen anything designed so that it can do everything well. Whenever they try to design too much into something they always end up with something that does nothing well. Case in point, motorcycles. I have never run into a motorcycle that is great at off road and on the street. Instead, they are just bad at both. Same for rifles. No such thing as a hunting rifle that doubles as a top of the line target rifle. Same thing with knives and countless other things. I am not sure you should ‘muddle’ a good design by trying to make it double as a jet ski although I am sure you could. In fact I would encourage you to go the other way. Make the best jelqing machine in the universe. Then make the best stretching/hanging machine and so on. That way you can focus on the best way to approach each. I am not being critical. I would just hate to see a great idea fall by the wayside because “the stretching aspect is great but the other stuff don’t work” kinda thing.

Take a few a few steps back and don’t rush this. You’re on to something and if you do it right you’ll end up with something that has a huge market. Believe me.

Wow, DGA, that reply was more insightful and well thought out than this entire machine to date. Comments like this make me even more determined to run this to ground. Thank you.

Just finished plasma cutting the HMI into an old computer case side panel I plan to mount in the lid of the flight case. You should be able to just throw the case open and grab the rig. So far everything signal related is 4-20ma or current (RTD), so it should all get along in one cable, with the two exceptions being the armature of the motor and the heating elements being PWM. Then again I could place the Gecko drive in the J-box and just hit it with step/dir pulses through the umbilical, for that matter I could also throw the FET(s) I plan on using for heating in there too. From an electrical engineering standpoint I would then have a no brainer functional tether. Wish I had some extra automation connectors, one of those rectangular 40 or even 20 pin Amphenols sure would be nice, you would be able to pop this thing lose from it’s tether then (after undoing two QD tube connections too).

Thanks,

Another bought of show and tell.
Here is the arbitrary wave form generator along with the amplifier and the step up transformers to get the signals to a voltage enough to overcome skin resistance, also note the black rubber this is displayed on is special conductive rubber.
A Gecko 340 will supply the pull, pictured (black box with green lettering).

The panel is cut in but I don’t have the mounting brackets! I am leaning towards just RTV’ing it as I could cut the silicone away later if I needed it for something else still.

Here is the 1st look at the PLC slated to “run the show”, tis a Windows CE based, WinPLC from Automation direct. This should be an interesting hack, I am a ladder logic man from the start, and these program in flow charts. I have used them in the past but usually on the more math intensive projects. For the observant, no H2-CTRIO card is in place (the source of my high speed pulse train for movement of the Gecko). Also pictured are my planned power supply, E-stop, Valves along with one special “vacuum” valve (normal valves stick when hit with vacuum), possible J-box in proposed position and Joy-Stick override box (in need of re-labeling).

Now the question folks must be asking themselves, can this fool really put all those pieces together?

You betcha!

Darn hit my attachment limit for 24hours, guess nevermind, but trust me, it’s cool stuff :)

Just reading this last post tells me you are way out of my league electronically (you got a plasma cutter too you lucky dawg?). In my limited experience 4-20ma is higher than I have seen RTDs usually deal with for example so I know I can’t be of any help there. However, this is not my area, it being more mechanical.

Quick connects would also make your job a lot easier in assembly and disassembly but are not absolutely necessary for testing purposes. If testing the mechanical aspects do not go smoothly quick connects will be the least of your concerns at this stage.

You haven’t mentioned preliminary mechanical testing at this point and I suspect you are not quite there yet but I may be wrong. Have you started testing the mechanics yet and if so what aspects have you tested? If not, what aspects do you intend to test once you reach that stage? How do you plan to test each aspect? Lastly, what do you intend to do your preliminary testing on (not yourself I hope)? I am sure there are materials that can indicate if things are too harsh for a penis, at least at the beginning stages.

By the way, if this stuff is proprietary don’t feel obligated to answer specifically. I just think a breakdown into specific movements and subsequent testing could be very beneficial.

Keep pluggin’!

The RTD will not be 4-20, it’s a normal PT100 (100ohm), I will be placing this into a wheatstone bridge and reading it’s temp as a voltage technically, then scaling it into degrees (I don’t have a regular RTD card on hand).

Mechanical testing of the stroke has been done with a D’cell battery and it’s smooth as silk! The servo gearhead is rated at 24VDC and to be spinning 100RPM at the output shaft. With about a 1” pinion gear X PI back of the napkin I could move at 300IPM+.

I need to add a small airbrush compressor into the case and it would be totally self contained and I would just set the compressor to a safe pressure to begin with. The air is only there to provide the “clamping” force after all.

Looks like a section of 2” PVC capped at both ends will be the vacuum accumulator tank I spoke of earlier. The vac pump will run closed loop with the vacuum transmitter and just keep the stored vacuum at the set level, so that when vacuum is requested there is a volume of it available.

F4

I kinda figured it would be smooth. What kind of force is it generating on the stroke and return and what kind of clamping force are we generating?

The accumulator tank should keep things smooth and consistent. Nice touch.

I have not attempted to measure or calculate the pulling force of the unit, but from my earlier timing pulley calculations, it’s safe to say it will be capable of excessive force. The clamping force is just based on air pressure, I have a servo based air valve and it is controllable from 3psi on up to supplied level, could be 150 pound per square inch! This would chop it off, luckily the single ply inner tube I am using will limit the actual force by popping if say a number format error surfaced and the pressure got commanded full on by accident.

The tank is storing vac so that you are not waiting for this little vac pump to pull you back in (assuming your not erect), I want it to “slurp” things back into place smartly.

Testing shmesting, Damn the torpedoes!

On another tangent, the HMI I am using supports chart, graph, and trend plotting with several meg of memory on board with a CF slot too (I know, who uses CF anymore). I will HAVE to buy one of those transducers to ping the head from the end of the tube, and get real time accurate measurements of length for the graphing! Also I used a certain laser sensor made by Banner a couple years ago and it can measure the width of objects up to 4” wide from a few inches away, like through my clear acrylic, this could be tracked on a graph too. One problem, this sensor was about a grand! I think I know where a spare is though. These last two just oh so cool things are really some of the easiest frills I could add. This HMI being ethernet also has an email server and web server, so others could log in and check your progress, not that I would want ANYONE watching me like that.

Well, here she is sitting on the end of her tether. And another of the quick throw together control set I just bodged up in the last couple hours, this is not to be the final controller, that’s the one with the radiation stickers.

F4

I wanted to gloat about how this was “not bad” for something a guy threw together in a weekend with stuff just laying around the house. Then I got to thinking, maybe my wife didn’t leave me for lack of penis size after all, but for having too damn much crap around the house. Kinda makes a fella take stock of his situation.

Just sayin.
