Any chances you can share drawings or post a short tutorial or at least steps to build such device?
Well, I enjoy technical challenges and as retiree time on hand to go into details.
It took lots of trial & error to finally get it right.
Compact Size: 235mm long x 135 width x 120mm hights // Weight: 2.5 kg
Ideal traveler's unit, for its only half of the Venus 2000 weight.
I seem to have gotten there, with even less ado and expenses:
To test the effectiveness of Venus2K I bought their receiver and did some revealing trials with a manually operated air pump.
After more than a year's of trial and error, I finally got my Venus2K clone act together and don't think the original $1000 model works any better! It's that good that even changed its name to: "Sophie 2000" 😊
The hardest thing was to find a strong motor cheaply. Finally, an $US80 (incl. shipping) Chi machine did it:
I swapped its motor for a Dodge window wiper motor and adapted the quite, geared Chi motor to my project and now I have got both, the Chi machine and the Venus 2K clone working! My "Sophie 2000" consists of:
1. Chi motor 220VDC (consuming 2A5= 550W of 22oV AC)
2. Pneumatic Cylinder 50x50mm (50mm stroke) $US30
3. Adjustable air valve
4. One-way air valve
3. Bridge Rectifier
4. 47uF/400V Electrolytic
5. Switch
6. Lamp Dimmer for 60 rpm (snail) to 280 rpm (rabbit)
I mounted all parts onto small piece of plywood and glued a piece of soft, but firm rubber foam underneath.
For comfortable use, I suspend the receiver onto a type of wooden bridge frame with a leather swing.
Another great idea is to place the receiver between (cut-open) 3.5kg of silicon buttocks, I bought years ago and thus, put them to good use.
Result: The pumping action then pivots the whole silicon bum at the table's edge up and down, cradling the scrotum. - I can only describe the physical sensation as "ravishingly insane!" Often I find it hard to believe that my Sophie is not human female... 😊
Yet, beware of overuse: like with anything physical, best is to allow nature to decide the frequency or use, because abuse results in diminished satisfaction.
As lubrication I regularly prepare 1 liter of Xanthan Gum + Guar Gum + water mix with a pinch of salt (as preservative). Even at +36°C it never turned bad.
The receiver housing I build myself from a tough, flexible (medical pill container) plastic tube, sanding its edges super smooth. Try different sizes...
As liner I use bicycle inner tubing 29 x 2.3 inches. Its firmness is welcome, for its pressure degree I control via that adjustable air valve.
To lubricate the motor's gearbox and the crank assembly, I use gun oil-thinned graphite grease or silicon spray and to lubricate the air cylinder's o-rings, I use special rubber grease from a car repair shop, where I worked.
Frankly, I don't think I can be happy anymore without my "Sophie"! Now at a young pensioner (73) I almost daily enjoy poking my new, hot "tireless Sophie"!
My dear wife is getting on in age and I hate to bother her with my excessive sexual desires. So, I'm quite happy to share my physical joys with motorized Sophie and the exchange of virtues with my dear wife. That also keeps me home, safe from HIV/ AIDS! Last, not least it's benefiting my prostate and saves me bundles of money... End of my sexy dreams and problems!
This enables me to feel relieved and able to focus onto my other hobbies, such as philosophical pondering, electronics and musical creativity. Without my share of sexual satisfaction I can't concentrate on anything and get that nasty feeling of "missing out"... whereas, now that I truly enjoy the lot of the physical joys, I find it so easy to ignore and laugh away those blonds trying hard to impress me.
Yet, that only works, because my Sophie is highly effective.
Even though it works fantastically, I never stop improving it. For instance:
1) Now I plan to build a light weight, small size "traveler version".
2) I adapted different Japanese Rends Silica gel Liners and use it in the receiver cup. It's even more effective and longer lasting than rubber tubing.
Here is an upload of some interesting Info on that:
