This code is an ESP32 rewrite of the core NoGasm project by Rhoboto: github.com/nogasm/nogasm
Using an inflatable butt plug to detect pressure changes indicative of pelvic floor contractions, this software, and associated hardware, is used to detect when the user is approaching orgasm and control stimulation accordingly. The net result: automated edging and orgasm denial.
NoGasm WiFi and NG+ devices both support a Websocket connection and a Web UI. The current Web UI can be accessed at nogasm-ui.maustec.io. The source code is at github.com/maustec/nogasm-ui.
Documentation for the WebSocket API can be found in doc/WebSocket.md.
If you have hardware already, please see examples/config.json or your own config.json file
shipped with your SD card. Note that this JSON document does not support comment preprocessing,
and is automatically generated. Here is a quick summary of config variables:
| Key | Type | Default | Note |
|---|---|---|---|
wifi_ssid |
String | "" | Your WiFi SSID |
wifi_key |
String | "" | Your WiFi Password. |
wifi_on |
Boolean | false | True to enable WiFi / Websocket server. |
bt_display_name |
String | "Edge-o-Matic 3000" | AzureFang* device name, you might wanna change this. |
bt_on |
Boolean | false | True to enable the AzureFang connection. |
led_brightness |
Byte | 128 | LED Ring max brightness, only for NoGasm+. |
websocket_port |
Int | 80 | Port to listen for incoming Websocket connections. |
use_ssl |
Boolean | false | Enable SSL server, which will eat all your RAM! |
hostname |
String | "eom3k" | Local hostname for your device. |
motor_start_speed |
Byte | 10 | The minimum speed the motor will start at in automatic mode. |
motor_max_speed |
Byte | 128 | Maximum speed for the motor in auto-ramp mode. |
motor_ramp_time_s |
Int | 30 | The time it takes for the motor to reach motor_max_speed in auto ramp mode. |
edge_delay |
Int | 10000 | Time (ms) after edge detection before resuming stimulation. |
minimum_on_time |
Int | 1000 | Time (ms) after stimulation starts before edge detection is resumed. |
screen_dim_seconds |
Int | 10 | Time, in seconds, before the screen dims. 0 to disable. |
screen_timeout_seconds |
Int | 0 | Time, in seconds, before the screen turns off. 0 to disable. |
pressure_smoothing |
Byte | 5 | Number of samples to take an average of. Higher results in lag and lower resolution! |
classic_serial |
Boolean | false | Output classic NoGasm values over serial for backwards compatibility. |
sensitivity_threshold |
Int | 600 | The arousal threshold for orgasm detection. Lower = sooner cutoff. |
update_frequency_hz |
Int | 50 | Update frequency for pressure readings and arousal steps. Higher = crash your serial monitor. |
sensor_sensitivity |
Byte | 128 | Analog pressure prescaling. Adjust this until the pressure is ~60-70% |
use_average_values |
Boolean | false | Use average values when calculating arousal. This smooths noisy data. |
* AzureFang refers to a common wireless technology that is blue and involves chewing face-rocks. However, the trademark holders of this technology require the name to be licensed, so we're totally just using AzureFang.
Hardware builds for this project can be purchased from Maus-Tec Electronics, at maustec.io/nogasm. OSHD pending final review.
Hardware development and assembly helps keep pizza in the freezer and a roof over the head of the maintainer. Your support helps a small business grow into something neat, and ensures future devices like this can continue to be produced.
The User Guide for the hardware can be downloaded at doc/Edge-o-Matic_UserGuide.docx.
If you want to breadboard this project, I've included the pinout from the ESP32 below. Please reference the original NoGasm schematic for specific designs regarding the pressure prescaler and MOSFET wiring. Alternatively, ask Mau about their breadboard-friendly MOSFET boards, which can directly drive your power rails and your motor from 12V.
Full pinout details are in the Operator's Manual.
The RJ45 Jack IS NOT ETHERNET! That is a balanced twisted pair extension of the I2C bus on the controller, and is available as a convenience for future development, dongles, and accessories. It carries +5V and SDA+/-, SCL+/- signals. You must use an I2C redriver IC or compatible module to interface with this. Additionaly, this is terminated at 100ohm assuming standard CAT5. We recommend SparkFun's BOB-14589.
| Pin | Signal |
|---|---|
| 1 | SCL- |
| 2 | SCL+ |
| 3 | NC |
| 4 | +5V |
| 5 | GND |
| 6 | NC |
| 7 | SDA- |
| 8 | SDA+ |
The official hardware looks like an ESP32-WROOM dev module. Conveniently, you can use the same module for your own builds. This is currently developed in the horrid confines of the Arduino IDE for the compiler toolchain. Install ESP support for Arduino. Use your fav editor. CLion is great.
This project uses the following libraries:

- ESP32Encoder library by Kevin Harrington
- Adafruit SSD1306 library by Adafruit (click "Install All" if it prompts you for dependencies)
- ESP32Servo library by Kevin Harrington
- ESP32 I2C Slave library by Gutierrez PS

Any changes to configuration values should be linted. Run ruby bin/config_lint.rb to check documentation, serializers
and structs for consistency.
