Digitally controlled constant strain extender

APTalways reduces the apparent length of the penis because the ligaments are attached to the pubic bone and APT shifts the upper pelvis forward and consequently the pubic bone backward. But APT is independent of other PE. A well executed heated strain protocol will increase flaccid whether you correct the APT or not. But if you have severe APT, correcting it will also add to your flaccid.

@Tutt
Would correction also net some BPEL gains as well?

Yes. Perform an experiment. Get out your ruler and perform a typical BPEL measurement. Then while you are doing that, tilt your hips into more of an APT position. Watch what happens to your BPEL.

Having read multiple threads on US & PE, I’m in on this. When you have a chance could you post/PM a complete & detailed parts list and some form of assembly guidance. I’ll admit I’m a little intimidated by this project (I have no engineering background whatsoever), but I think by building it myself I can have a better appreciation of the functionality of the unit and be in a better position to make modifications as desired/needed. I will collect another set of data points for the tribe. Whatever help you can provide would be greatly appreciated. Thank you.

I’m willing to build this right away and have an engineering background so can provide code fixes or mechatronic feedback. Do you have a list of parts so I can start ordering parts this week?

You have to read the thread and locate the components in the discussion.

Which exercise gives the most results? Pump or extension

I’m pretty sure he said that the parts list he posted earlier is not the final parts list that he’s putting together now.

Hello. Why is it taking you so long to start training? When do you plan to start?

I didn’t realize people were posted in this thread - Thunder’s place doesn’t give me notifications so I missed the last messages.

I started last week actually with my first session - I got a blister on my shaft, so I might have to take a few extra days off until it fully heals. I do admit that I delayed a lot (and only started last week) because I’m super perfectionistic and I was trying to build an addition that would automate the movement of the US head for a fairly hands-free approach (I’d still have to put the US head back on after the 15 minute auto-off). I’m 90% there with this addition but I ordered the wrong motors (in terms of RPM) - I’m yet to order the right motors to fix that and when I do, it will take another month or two for me to receive them. Anyways, in the mean time, I plan to continue with manual movements of the US head - i.e. sessions every ~8 days until I complete my build with the new addition.

I’ll start a separate log soon with a detailed write up of my protocol and results but here are some quick results for anyone interested…these are the various lengths I measured at different increments of load.

0.5kg 8cm
1.0kg 9.5cm
1.5kg 10.3cm
2.0kg 10.7cm
2.2kg 11.7cm

Using these figures and the standard formula, I’m getting a strain value of 23.16% which is probably impossible. I’m not measuring in the standard way like Kyrpa - I’m using my length at 1.0kg, then my final measurement at 2.2kg and plugging those into the formula. I’m also measuring inside my device - so from inside the ring that sits on my pelvis to the tip of my glans. I’m sure there are lots of confounders in there such as glans engorgement, etc, but I’ll be honest, there was sooo much going on in that first session and so much to focus on (so much so that I forgot to run a timer to track total session length). It’s truly lots of subskills just executing the protocol and I’m sure in a few sessions I’ll get the hang of it and do better.

Finally, you have begun! Congratulations! Of course there will be flaws in the beginning. That’s normal.

What formula do you use?

I really hope you succeed. And that you won’t quit like fdersby.

fdersby messaged me before leaving the forum - he was in the process of moving and said he’d hit his goal and was starting a new chapter in his life.

I used (post - pre) / pre (with pre being the length at 1kg).

Thanks - and indeed - at last! Lol.

Yes, I hope to iron out the flaws after a few sessions. I hope I do too and I feel pretty confident in the process.

Hi! Good to see you back. I’ve finally gotten caught up on most of these US threads/logs and was looking forward to your return. I sent a PM a week or so ago, but now that you’re back on here, easier to just post on here. Were you planning to compile an official parts list any time soon for those of us who see this as too overwhelming to begin on our own? It looks like, for example, the Totalman extender you were using is different from the one sold now, and Tutt’s recommended weight scale is not available (though he did recommend a different extender that appears to be in stock).

I’ve begun some light FIR hanging, but do see this as a much better and less time consuming method, if I could manage to get a machine together for it.

@Easygainer
Have you thought about replacing the fish scale for measuring the pulling force with a load cell that feeds the data to your arduino board ?

I will be building something similar that fdersby built, but I will use an ESP32 controller, which is very similar to an arduino board. The ESP32 has a WiFi integrated and it also has a web server on the board.
I plan to use a simple load cell from Aliexpress that is based on HX711 IC instead of the hanging scale. It will send the load data to the ESP32 in real time, and ESP32 can display that on the webpage as a gauge. This means that you can connect the phone to the ESP32 using WiFi, and continously check the load.
You could also use that load data from the load cell to make automatic changes with the stretching protocol. You could tell the ESP32 to keep the strain rate at 1%/min until it reaches 1kg, and then automatically reduce the strain rate to 0.5%/min. Then after it reaches your 0.17MPa load, it would automatically stop extending and just hold.
