The 915Mhz radio version is sold out. Only the 868Mhz version (e.g. for Europe) is still available

What is it?

The body interaction 1 is a tiny microcontroller board for building vibrating devices like (sex) toys. The vibration strength is controlled by motion. It is equipped with a radio module for wireless data transmission. The body interaction 1 includes a LiPo battery and a capsuled vibration motor. Supports the Arduino IDE and Codebender.

Why did you make it?

Yes, we like sex toys. But we don't like cables, empty batteries and tiny switches for controlling the toys. Furthermore we want to build our own sex toys. We like to invent new toys, make a 3D design, print them on a 3D printer and the play with them. Or casting a silicone toy with the vibration motor inside. We would like to program our sex toy as we like. And we like several toys that are able to communicate with each other. So its possible that they syncronize vibration or "stimulate" each others. And we hope that there are other people who share there cases, Arduino sketches and ideas.

What makes it special?

body interaction 1 is small, cheap and you can start at once. You can program the board with the Arduino software (IDE) or in a web browser (eg. codebender). A demo sketch is already uploaded to the board. Download 3D cases from Thingiverse, print them, assemble the body interaction 1 and have fun! Or invent your own toy using 3d modelling software.

More technical staff

body interaction 1 has a Atmel Attiny84 on board, a LiPo charger (via USB) and a LiPo battery. The encapsuled vibration motor is controlled with PWM, though you can vary the vibration strength as needed. There are two additional I/O ports which can be used for other sensors or actuators (PA0 is Arduino pin 8, PA1 is Arduino pin 7). Programming is done with an ISP interface (2×3 pole header). The board has BMA020 accelerometer and a RFM12B (915 or 868 Mhz) radio module. Size: approx. 20x36mm. Open Source Hardware. Supports the Arduino IDE. You need an ISP programmer (eg. USB tiny ISP) for uploading new programs (sketches) to the body interaction 1. There are two options for the wireless transmission chip. You can select 868MHz or 915MHz (US, Australia only) radio module. Cases are not included.
