Mod showcase: Dildo minigame

[allahere]

TLDR: A minigame where you have to suck on a real dildo to win. Also the dildo can cum.

 

While I am sharing the actual mod here, the setup is very involved and DIY, so this post is more of a showcase. Maybe if people are interested, I can share more parts of the setup, and I or others can try to make it more accessible. But for now this is a proof of concept. If you have ideas, please comment!

 

What is it and how does it work?

 

X-Change life already includes basic support for sex toy remote control via buttplug.io/intiface. This mod aims to vastly extend this support and making it more interactive. It is in effect a machine you can give blowjobs to. It consists of three interactive units (shown numbered in the picture on this post):

 

1. The Tempest SSR1. This is a linear motor that is normally used for an onahole to get a handy-like experience (handy the sex toy). For this mod, it is instead equipped with a dildo. Right now this part is not interactive, the SSR1 serves as a convenient holder for the dildo I had available.
2. A distance sensor (VL6180X, a time-of-flight/TOF sensor) with microcontroller. When you're sucking on the dildo, this measures the "insertion depth" repeatedly. It detects how well you're sucking ?
3. A pump (from a disassembled water gun) with microcontroller that attaches to the dildo hose to spurt fake cum (water with salt for taste and food-grade calcium carbonate for color).

 

These components connect via bluetooth to an android app that provides a buttplug.io-compatible server for the game to connect to (hence the "Generic Vibrator" in the showcase video, that's what the app exposes via bpio).

 

The mod itself adds a new minigame next to the normal blowjob minigame. Instead of having to press the right direction keys, you have to blow the dildo. Movement is detected using the distance sensor. As you move, the pleasure meter goes up the same way as in the vanilla minigame.

 

A second function of the mod is that the fake cum pump is triggered when you receive a facial or cum in mouth in-game. Who doesn't like being surprised by random facials from a dildo?

 

I've uploaded a video of the device in action here. You can see the basic blowjob minigame, and if you look carefully, you might even see the cum function at the end (you can definitely see the hose jerk as it fires, though).

 

Why can't I use it?

 

As I mentioned, all of this setup is custom: Custom 3D-printed parts (except for most of the SSR1), custom printed circuit boards (PCBs) for the distance sensor and the controller boards, custom firmware for all microcontrollers (incl the SSR1), a custom android app, and finally this mod. While I'm open in principle to sharing all the schematics and code, I first need to strip my real name from them ? Much of the setup is also just harder than it needs to be, e.g. the custom PCBs could probably just as well be breadboards if another person wanted to replicate this. The android app could be replaced by serial communication similar to the vanilla ssr1 firmware.

 

I hope a person with knowledge of microelectronics and programming could replicate this setup based on this post. I am willing to give advice on any details too. But to make this more accessible would need a lot more work.

 

Future ideas

 

The first idea that is possible with this hardware is a "facefuck" minigame. The distance sensor is actually mounted on a rigid bracket where you can rest your forehead. The SSR1 can then facefuck you, and with the distance sensor it can measure that you actually stay on the dildo. This feature is likely what I will implement next (in fact some code for it is already in the repo), but it's a bit more complicated than the blowjob minigame with how X-Change Life is structured.

 

I would love to hear more ideas if you have any.

 

What else can you do with this hardware?

 

Now this is a bit tangential, but I did not initially design this hardware with X-Change Life in mind. I've implemented other "games" on it before:

 

• The distance sensor was initially designed for teledildonics: Remote controlling an onahole like the ssr1 by sucking or inserting the dildo.
• The SSR1 and cum pump can be used to play modified funscripts. Rest your forehead on the bracket that holds the (unused) distance sensor, play a blowjob funscript, and get your throat fucked just like the person in the video. Cum function is also useful for this, just needs some modification to the funscript.
• I've built a basic mod for SuperDeepThroat where your head movement is translated to in-game movement using the distance sensor (there is already a mod for the reverse, controlling an onahole or the dildo based on the in-game movement). But this is kind of boring because there's not many SDT scenarios where you play as the girl.

 

If you want details on any of these, I'm happy to share, they're just not directly related to this mod.
