The big penis and mens' sexual health source, increasing penis size around the world.
how noisy is the pump? I saw the same pump on amazon and was intrigued. Such a high vacuum pressure isn’t a good idea for penis pumping, but I thought if you connected it up to a variable DC power supply, and dialed the voltage back, it would be quieter and the vacuum would be closer to the 3” - 8” of vacuum for normally used for pumping.

Very nice veloce. MrHardon your live equipment in a cardboard box scares me, I don’t like seeing dangerous how to photos, you need to make it safe before someone gets hurt or a starts a fire.
We’re talking about a prototype, and some changes are necessary for sure. But this setup uses 12v DC, and that probably can’t start a fire.

Hi Retro06,This is the common one used. DP-4000 DIGITAL MAXIMIZER, penis enlargement products and that’s what I use and recommend.
If you don’t need a pulsing pump, and add a vacuum gauge and a variable power supply, this would cost about $40 to $50 instead of the $470 price for the CTC pump.

Would rather pay someone for it because my profession doesn’t afford me time to build it myself so if anyone’s got a price aside from 470 lemme know
But I would definitely need the pulse pumping
Not dangerous at all! And yes, VERY loud. I stopped using it a while back. I have been cooking up some other ideas though, I’ll try to post them sooner than later!
August '15 - 7.0 x5.5
September '15 - 7.25 x 5.75 October '15 - 7.5 x 6.0. I am truly astounded that this works.
November '15 - 7.5 x 6.0 Time off and inconsistent routine = No Gains. Goal: As far as it will growx7
I was going to start a new thread about this, but I guess I haven’t made enough posts over the years to qualify, so I’ll post this here.
After mulling it over for quite a while, and being inspired by the above OPs thread utilizing a Velleman VM-188, I’ve built a DIY vacuum pulse controller for my Vacu-Tech VT-9000 that for a first effort, I’m pretty happy with. (See photos).Parts used:
1 x Hammond 1591D project box
1 x Velleman VM-188 Pulse/Pause timer
4 x Adhesive PCB standoffs
2 x 5K panel mount linear taper pots with knobs
1 x Clippard MNK-2V 5-turn panel mount needle valve plus 2 x 3/16 10-32 UNF hose barb fittings
1 x Replacement solenoid valve for Keurig coffee maker
1 x 12VDC power supply with matching DC power socket jack
1 x Miniature toggle switch
2 x 3/16" hose barb panel mount CNC quick connectors
1 x 3/16 T fitting
1 x Loom clamp from hardware store to mount solenoid valve
4 x small rubber washers to make a shock mount for solenoid valveDescription:
A 12VDC wall adapter powers the timer board, which in turn controls the solenoid valve. On/Off to the board is controlled by a miniature toggle switch.
The VT-9000 (or any pump) is connected to the left side hose connector to a T-fitting which is connected to one of the solenoid ports and also to the needle valve, then from there out to the cylinder. When the solenoid is not energized, vacuum is supplied directly from the pump to the cylinder, with the rise of vacuum controlled by the needle valve. When the solenoid energizes, vacuum is vented out the solenoid to the atmosphere, with the fall of vacuum also controlled by the needle valve.Notes:
I already had the Hammond box on hand from an older project and it had some previous holes in it which I tried to reuse, creating some challenges getting everything squeezed in. If I’d used a new box, I might have better optimized component layout.
The timer board came with trim pots which I removed and replaced with the panel mount pots.
The loom clamp is held on by a 10-32 flat head screw up from up from the bottom and held in place with a nut to create a post. The rubber washers on both sides of the loom clamp create a shock mount to help quiet the solenoid inside the box.
The controls on the top are a) power switch, b) pulse time in sec, c) pause time in sec, and d) flow rate.
The timer board is configured with jumpers to a) continuously loop, and b) use a timer range of 1-60 seconds.Improvements I’d like to make:
Add some labels to the controls.
Add a miniature vacuum gauge the cylinder side. Even though the VT-9000 has a gauge, that’s on the supply side and only shows the maximum before the needle valve. It’d be safer to actually see what’s going on in the cylinder.
A power status LED.
A pulse status LED.Future possibility:
Since the solenoid valve was designed to work with liquids, it should be possible to modify the hose connections and turn this into a wet pumping controller, similar to a Mr. Fantastic device.Cost:
Probably around $85-95.
The price kept going up as I kept thinking of enhancements, but the timer board, solenoid valve, and needle valve were the most expensive parts. The rest was small stuff.
Hello guys. I registered on this forum to reply to this post, and hopefully contribute moving forward. A few months ago I bought a CTC DP-4000 to do pulsed pumping. I have tried everything to get it to work and at this point I’m resigning it as a failure.
In response, I’d like to try my hand at replicating the excellent job that’s been done here to take a custom approach. I’m an absolute novice at electronics but I’m prepared to do independent research and learning to make it work. Fact is, there just isn’t an off the shelf device that does what I’m looking for.
I don’t mind if I’m asked to create a new thread when I’m able to do that, but I’d like to detail my research and knowledge here and the project as it proceeds over the coming months. The post given is a great starting point. If anyone would be interested in helping me to achieve this, I plan on making a detailed "for dummies" construction guide if I get far enough down this road that other people can use.
Thanks
Go for it! It would great if you can figure something out and then share a step-by-step production guide for the average TP member who isn’t an engineer or experienced with electronics.
Good luck!
Rock out with your cock out!
Go for it dude.
Start 8/15/18-BPEL-6.75” MEG-4.625”
2/17/20-BPEL-7.125” MEG-5”
Goal- 8”x5.5”
There are a few guys here that can help with the technical stuff.
Adding a reservoir can help with the noise btw.
Go on!
Thanks for the replies and interest. If there is anyone here that could help with the technical stuff, you are welcome to reach out to me, it may accelerate this process significantly and get this out to you all sooner
Alright, so here is my first pass, including the adaptations of an inline pressure monitor and status LEDs. I think this is basically how this will work. Its worth saying at this point that this system doesn’t actually vary the pressure level yet; I need to investigate more how to do this. I’d also like to include 2 alternating states while the unit is on, either:
- Pump maintains monitored/chosen pressure level (so would need to include a detector and a re-engagement mechanism when the pressure drops below)
- Pump actively decompresses to normal atmospheric pressure
More research incoming
So I see there is no pressure control, just on/off action on the pump?
You can control the pressure with a manual valve or a solenoid valve between the pump and the T connector, but the solenoid one would require PWM to control it.
To simplify things you may get a vacuum regulator, so you can get rid of the gauge and T manifold as you would have all in one:
IRV10-C06BG | SMC Metric M6 port 140L/min Vacuum Regulator, -100kPa to -1.3kPa | RS
I do not recommend push-in fittings, however. They tend to leak
Excellent thanks, I’ll look into this

Archangel and I traded PM’s where we discussed errors in his description and chart, which need to be revised. He is describing a pressure system, not a vacuum system. It is important to understand the difference when designing the automated pulse pump project, particularly when setting up the vacuum regulator.
A vacuum system removes air molecules from inside the cylinder and releases them on the outside of the cylinder, thus reducing the atmospheric pressure in the cylinder to below 0 psig, i.e., creating a vacuum.
A pressure system takes air molecules from outside of the cylinder and releases them into the cylinder which increases the pressure inside the cylinder.
The diagram shows a pressure gauge, not a vacuum gauge. The line on the vac pump states air in from outside the box. It should read air out from inside the box (cylinder).
Decompresses means to reduce pressure. Re pressuring means to reduce vacuum by increasing pressure.
Initial: 7” BPEL; 6” NBPEL; 5.25” - 5.5” MEG
Current: 7-7/8” BPEL; 7-3/8” NBPEL; 8.5” BPFSL; 6.5” MEG; 6”x5” Flaccid.
Goal: Improved/consistent EQ while managing ED. Secondary: maintain current stats.
