Automated Pulsed Pumping

Automated Pulsed Pumping

I’ve been pumping/jelqing/hanging off and on for a couple of years and finally got more serious about PE the last few months. I like the ease of pumping but I wanted to automate it. I looked into the auto-pumps for sale and although I would love to have one, they are quite expensive. So I built a simple device to auto-pump on the cheap.

Items needed:
Vellemen VM-188 pulse pause timer
12 volt diaphragm vacuum pump
AC to 12v 2A DC power supply

Extra wire, and your pumping equipment (pressure gauge, tubing, cylinder) will also be needed. I found all the wire I needed on an old PC power supply, just cut of the molex connector and get as long as a strand you can find ( you can cut it down later).

Now wire it up! The timer comes with easy to read diagrams that give exact instructions. Here are some pics of my setup. I used an old laptop power supply.

Disclaimer: BE CAREFUL
If you don’t understand the diagram for a 12v setup find someone who does. 110v or 220v is dangerous if you don’t know what you are doing.

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

Do you have a pressure gauge in the system? How much vacuum can it pull?


The primary goal of PE should be to make your penis as healthy as possible in both form and function. If you do that, increased size will follow.

If I just hook it straight up to my mity-vac it pulls 19.5 in hg. My whole system the cylinder will pull about 14-15 in hg. I don’t use any sealant or tape, everything is just a friction seal so I can take it apart as needed. I also have it hooked to about 6ft of 1/8 tube and I’m fairly certain that it causes loss of vacuum.

That is a lot of vacuum for sure. How do you control the pressure? Do you have an adjustable pressure bypass valve in the system?

My air line runs from the pump to a T fitting, one side goes to my mityvac which acts as gauge and emergency pressure release, the other side goes to a second T that splits to a ball valve on one side and the line to the cylinder to the other.

Thank you for moving the thread to the appropriate section! I don’t have enough posts (yet) to start a thread in the right place.

Interesting. Just received a 12V air pump, were going to DIY an electric pump device based on Micro Controller Unit (got the necessary skills, so it’s going to be a big problem).
So silly that the ready solutions are expensive — like 450$ for the CTC DP 4000 — c’mon, this is just a boxed MCU + air pump, not a rocket science.

Well, anyway, how’s the feeling? Is that worth it?

Computerized, the programs and superior vacuum pumping ( rotary design ). Some of these expensive pumps ARE worth it and will be the last pump you by for many many years.

It’s pretty good, works better with my 1.75” than my 2” cylinder if I let it cycle down to 0 in hg. I always assumed the expensive ones you can buy are because they have quiet pumps which are $$$ expensive vs the $10 12v pump I have that is too loud. I’ll be getting a muffler or something for it.

I could definitely see a good stretch coming quicker than usual and my hand wasn’t tired from the pump and release.

My next project will be a 12v heater I can wrap the tube with, keeping me at about 100-104 degrees F during my pumping session.

Nice work. Whats your pulse length, duty cycle, and have you noticed any trends while adjusting these parameters?

I’ve found that for me personally a max vacuum of 3” hg is a good starting point in the 1.75” tube. I cycle 1 second on / 3 off to slowly warm up. Once I start packing the tube I raise the pressure slowly to about 5” hg and leave it there for about 10 minutes. Once the tube is fully packed I really start to feel a stretch. I hit 19cm in the tube within this timeframe. I haven’t had any trouble with circulation while using this new pump.
After 10 min I stop and jelq for a bit, stretch, and switch to the 2” tube.
Same routine as before just a larger tube and I’ll go for about 15-20 minutes. I usually will hit 19.75cm before stopping. (I’m so close to 8”! In the tube anyway.)

Your experience may be totally different than mine. I’m on a PE break at the moment. I pinched a nerve during my clamping routine, I went one click to far I guess. Just a little numbness at the base but I should be fine in a week or so. It’s already much better after only 48 hours.

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 valve

Description:
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.

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.

For sale

Hello I was wondering, if it is possible to buy one?

Hi Retro06,

This is the common one used. https://ctc-company.com/product_info.php/digi-pump-p-37 and that’s what I use and recommend.


Now: 9" BPEL x 6" MSEG as of 12/16/2016 This is my story...and a few progress pics of me here.

Then: 6.25" x 4.37" in 8/2009 Are you new to PE? Here's some advice I wish someone had given me when I first started.

My big secret? My methods. There is no "Holy Grail" of Penis Enlargement. Only time and effort works. I'm *8* years in and counting. All you have to do is put the work in and keep the faith. Also Fitness helps too.
