What is it?

This is a development board for building wireless, internet connected vibrators. The "body interaction 2 (BI2)" board can be controlled from an app or a computer. A colorful LED is included which can be extended to a LED chain. Each LED can be controlled individually. Up to three vibration motors can be connected. The board is powered by a LiPo battery (battery not included). A battery charger is included. For motion capturing a 9DOF sensor (accelerometer, Gyro and compass) is on board. The onboard microcontroller is the popular ESP8266 which is programmed with the Arduino IDE.

Why did you make it?

Building your own advanced sex toy is much easier with the BI2 board. Only basic programming knowledge is needed and a DIY attitude. Everything is included for an advanced vibrator with three individual controllable vibration motors. All you have to do is to make a case for the board where you integrate the motor(s). You can print your case with a 3D printer, you can make a molding form and mold the board and motors in silicone or you use other DIY techniques for making the case.

What makes it special?

The body interaction series of development boards is unique. Since 2012 www.bodyinteraction.org supplies the community with hardware and DIY instructions. It uncovers the technology behind modern vibrators and empowers you to build your own. You can be part of the sex tech revolution, you can make your own sex toy. Be a sex toy inventor. Use materials you like and where you know from where they come from. Code your sex.

Technical data: ESP8266 microcontroller, board layout based on Adafruit Huzaah. MPU9250 accelerometer, gyroscope, magnetometer. LED WS2821B (also known as Neopixel). Three motor drivers. If you use the LED only two motors are available. Micro USB connector for code uploading and LiPo battery charging. Control LED for charging. 40 mm diameter. Round. All connectors are JST-SH 1.00mm (3 connectors for motors, one connector for battery).

Options:

• pcb 29US$: BI2 development board only, no motors, no battery
• kit 39US$: pcb, two encapsuled vibration motors, two JST plugs, no battery. You must connect the vibration motor and the JST plugs on your own, soldering required!
• complete kit 49US$: identical with the kit, but I will connect the motors and the JST plugs for you.

Shipments to Germany include a LiPo battery with connector.
