I for one enjoy you being around X and appreciate your help (pm & other) when I went to electric pumping. I now use a Gast pump I got off e-bay and love it (as stated, one that can be used as a compressor in case someone asks :) )…& use the T-type fitting & finger for suck & release because all the other regulators just seemed a bit too much to figure out (at least for me right now), but am glad you are still working at it because one day soon I will want to upgrade to this type of system…

I’ve found something that I think might be very cool… a relay with independent on/off times. If it does what I hope, I would have almost infinite control of pulse cycles, not just the limited options with the pneumatic pulsator. Looks like I might lean back toward the solenoid option again instead of the pneumatic. I could use a pump that consumes less power, too, because it wouldnt require extra vacuum to run it. I’m a little short on time now but this sounds like an exciting idea… I’m going to pursue it further and see how it looks.

I’ve got the pump motor. The interval timer works great! I’ve just been playing with it. It’s totally programmable with independent on and off times, so I can adjust the on and off times independently. It doesn’t have to be just “equal time on as off” and it keeps cycling as long as you want.

The on time goes anywhere from 1/2 second to 300 hours.
and
The off time goes anywhere from 1/2 second to 300 hours.

A 300 hour interval will never be needed but thats ok. It’s accurate down to about 1/2 second, below that it’s a little “squirrely” but can be adjusted even lower.

So it can be adjusted to anywhere within these ranges. It could be 1 second on and 1 second off; 10 seconds on and 1 second off, 5 seconds on and 2 seconds off, or whatever you want to set it to. Any combination desired.

The problem now is the solenoid… I have one that might work but its expensive and I don’t know if it will vent “enough” to totally open up to the atmosphere.

Xaxxat, do you know a part number or what it would be called? I’ve tried “pneumatic valves” and “actuated valves” and “solenoid valves” but nothing really great is showing up. (The terminology on this stuff is not my forte!) Basically all I need to find is something like a water sprinker system solenoid valve, one side incoming and one side outgoing with a solenoid on it.

If I’m lucky I’ll get this going by Friday or Saturday, if not it will go into next week. I’m looking forward to getting started!

Thanks, Baz9. Glad to be of help. It looks as if electron has found the type of relay controller you had talked about.

electron, what kind of voltage does this relay controller handle? AC or DC? Most solenoids work with 120/240 AC or 12/24 DC volts. My current solenoid is a 24 volt DC 3-way. A 4-way should work too.

Do you have a link?

electron, you can find some valves here:

Asco is one of the largest manufaturers. Parker is too. There’s always lots of these valves on Ebay.

I’m using a Koganei vacuum valve, # V200E1. I got it on Ebay for $18. 00, shipping included.

I’ve attached a picture of mine. These valves are all similiar in size and function.

You can get the relay at Graingers. Look at it here: Grainger Industrial Supply - MRO Products, Equipment and Tools
Scroll down the page and you will see the 8-pin sockets to fit it into, I got one of those, too. Very handy with the screw terminals on them.

It takes a minute for the picture to download.

Another one that should work is here: Grainger Industrial Supply - MRO Products, Equipment and Tools

I looked at both of them yesterday in the store, but I liked the first one better, it is much easier to change settings quickly.

It runs on 110 line current just fine. It says anywhere from 100 to 240 VAC, 50 or 60 cycle will work to run it. The contacts themselves are independent from the line supply, so you could use little jumper wires to put line voltage through it going out to your solenoid, or use any other voltage going out to the solenoid. The contacts are rated at 5 amps 250 VAC, and 5 amps 30 VDC. It’s a DPDT relay.

You need to have a fictitious business name or these guys probably won’t sell to you. They did in the past, but the policy changed and they won’t do walk in customers anymore. :)

The OMRON H3CR-F8-300AC100240 looks very promising. The fact that it allows for repeatable cycles with independently variable on/off times makes it the one to have. It can certainly handle the current rating of any solenoid. My solenoid pulls 200 milliamps at 24 volts. 120 volt solenoids are fairly easy to find. They’re pretty much the industry standard.

The complaints I have against pneumatic pulsators are that they cycle too fast what need them for, and that the on/off ratios are not adjustable. They are fine for “fun”, but they are not very good for exercising the cock.

Have you decided on a solenoid yet?

Yes it’s a nifty little relay. The more I play with it the more I like it. I thought it might be neat to be able to set it to "pull" for maybe 10 or 15 seconds, then give you a 2 or 3 second rest and let the blood pump in. A cycle like that would give you much more stretching time that the 50:50 ratio, and still let blood pump so you don’t "turn purple." Maybe that can be my first experiment… finding out what the "purple ratio" is! It should reduce blisters and red spots, too. Anyway with this setup, I’ll be able to play with any timing ratio I want to.

I was going to go with a 120 V solenoid, then I don’t need a transformer for the valve. The line voltage is already there, so why not use it. Since I plan on using the "vacuum on" time ratio higher than "vacuum off" time, I need a "normally closed" or "non passing" solenoid, so the solenoid will normally be off, and only kick-in during the non-vacuum times. This will also let me have a regular "on all the time" vacuum pump with the flick of a switch, and not use extra power keeping the solenoid and timer on. The solenoid I picked up is here:

but I found another one that they have:

If it will work this will save me 25 bucks and has a higher temperature rating to boot. The first solenoid is a "3 way ported" and this second one is a "3 way direct" whatever that means. I hope it will work. I want to go get it tomorrow and hit the plastics shop for some acrylic tubing, sheet stock and glue.

I also got their little muffler, I’m going to be happy with this item, too:

It reduces the noise noticeably.

Here’s the pump motor, I should have put that up earlier:

Sounds like like you’re well on your way to having a sweet setup. Having variability in suction, timing and ratios is the trick. Baz9 had wanted to do a similiar setup. I’m sure he, as well as I, would like to see a photo of your final setup. Keep us posted! :)

xaxxat,

Ok, bottom line, what results have you been getting?

Sparkyx

I haven’t used the suck-n-release for awhile. I think I damaged my dorsal nerve when I was doing some intensive stretches. I was using a neoprene pad for a grip and I think I over did it. I experienced some pain in my dorsal area when ejaculating. I laid off PE and sex for awhile. I was ok for a couple of weeks and then I experienced it again the other day. So, I’m staying away from PE until I get this sorted out.

As to when I was using the suck-n-release, I did notice longer stretches each week. I have a clear rule attached to my tube so I can monitor my cock. When I began to add kegeling and infrared heat to the process, I noticed longer stretches. I noticed about a 1/16” to 1/8” increase each week. Over a month’s time, I believe I had about a 1/2” increase over my initial length. I didn’t keep a written record.

My routine was heat-stretch - kegel/pump w/heat - jelq. I noticed I had a longer, plumper flaccid. My erections were getting much better too. I never had any problems with a doughnut. I didn’t measure for any permanent gains, having figured that I hadn’t done it long enough to have achieved any.

I believe this method holds great promise. And, because it is so much fun, will be easier to maintain. I can’t wait to get started with it again. Hopefully electron will soon be able to give his input.

I hoped this helped. I do plan on keeping a written record when I restart.

Hey, electron, you got it working yet?

Yes, I got it together Monday night and its working like a charm. Tuesday I went to the plastics shop and got the acrylic tubing, and got a cylinder made. Since then, the last couple of nights I’ve been doing, well… research! Research is important too, you know! :)

I suppose I should drag out the cam and get some pictures up, huh?

Yeah, some pictures would nice. I agree, research is extremely important! :) Glad to hear it’s working. You’ve found a great way to simplify it all. I tend to over-engineer everything.
