Ardunio controlled inflatable buttplug

Post by occorics »

I have added a new internet-controlled toy to my system!
20200208_143615.jpg
It's rather simple, an electric pump, valve and pressure-sensor connected to a NodeMCU board...

The pump is rated at 0.8 bar / 1.5l/min
Sensor is a MXP5100 connected to the analog input.

It can keep a set pressure and will add or release air as needed. When you clench up, it will let some pressure out, but as soon as you relax, it inflates again! :twisted:
This can also be used to pulse the buttplug, which is FUN!

Like the nogasm project, it can detect edging and it's possible to register URLs that will be called when an edge is detected.
Now i only need to fine-tune the parameters and put it to a test in a session...

There's also a short video of the pulsing on my blog: https://owned-by-princess-shelle.blogsp ... ensor.html

wow occorics, very cool stuff!
I hope you will share more details about this project.

I've built a couple of similar devices. The more complex one used a hydraulic cylinder loaded with water as a pump, moved with an actuator. Totally different feeling from air-filled inflatable. The easier to build used -- as I assume you've done -- the guts of a blood pressure measurement device... pump, solenoid release valve, pressure sensor. I didn't need to bother with the pressure sensor, although I assume you've done so here. I too look forward to hearing more!

yes, i started with a blood pressure device, but the pressure range was way too low.
A water based solution sounds interesting. A peristaltic pump might work, too...

i'm working on making instructions, there have been so many requests... i was going to draw the schematics, but Eagle seems to require registration now, i'm looking for an alternative...
On the software side, i need to do some fine-tuning and host the webpage on the device itself.
Stay tuned...

i just had an idea... connected to an inflatable gag, it would deflate when you bite down and inflate again when you relax... :twisted: :gag:
need to try that...

Very "good" idea. :evil:

Yes, Occorics is up to no good as usual.
Bondage is like a foreign film without subtitles. Only through sharing and practice can we hope to understand.
A Jedi uses bondage for knowledge and defense, never for attack.

schematics and part-list, software will follow...
buttplug.png
part list:

C1 electrolytic capacitor, 47µF / 16V
C2 electrolytic capacitor, 1µF / 6.3V
C3 ceramic capacitor 10nF / 6.3V
C4 ceramic capacitor 470pF / 6.3V
R1 resistor 680Ω
R2 resistor 200kΩ (or 2x 100kΩ)
U1 5V voltage regulator, L7805 or equivalent
U2 MXP5100 DP pressure sensor
U3 NodeMCU ESP8266 E12 (an Amica board in my case, but any ESP8266 should work. The pin assignment might differ, double-check that)
U4 ULN2803 darlington array


external connections:

J1 12V power supply input. 500mA should be enough (depends on the chosen pump and valve, with my components, it's 250-300 mA)
J2 Connection to pump. I use a DAYPOWER LP27-12 which is rated at 12V, 230mA and delivers 1.5 l/min at 0.8 bar. A slightly larger pump is OK (the sensor goes up to 1 bar)
J3 Connection to valve. Any magnetic valve that operates at 12V should work. It needs to be closed when power is off.

A very educative piece you have here, thanks :) Can we maybe have a sneak preview/preliminary code to this ?

I have published the code on github: https://github.com/maid-marta/inflatable-bp/tree/master

There isn't much explanation, yet. I will add what's needed, so feel free to ask for missing information.
