Build your own
massager apps & mounts.

Open standards and fork-and-run reference code from Europe Magic Wand®. Two open standards, real implementations you can template, and a builder kit that turns one prompt to your AI into a working app.

Two open standards

Free to implement, including commercially — the one condition is accreditation.

Strong Vibes Protocol v1.0.0

The open BLE wire protocol: a client drives motor/vibration patterns (linear, sine, gaussian) over two GATT characteristics. Compact, datagram-based, self-contained enough to implement in one pass.

Strong Vibes Connect v1.0.0

The mechanical mount standard: a keyed diamond boss + socket clamped with a standard 1/4"-20 screw — rigid, single-orientation, printable.

Start with your AI

Paste this into Cursor or any AI coding assistant. It reads the spec and scaffolds your app.

paste to your AI
Build me a Strong Vibes client. Read the spec first:
https://raw.githubusercontent.com/amok-products/strong-vibes/main/protocol/strong-vibes-protocol.md

Then make a Chrome web app (Web Bluetooth) that connects to my device,
with a start/stop button, an intensity slider (0–100), and three presets.
Service 00001221-1313-71be-1221-785dfeabc321; write 0x1225, notify 0x1227;
every message starts with 0x10 and is ≤ 121 bytes. Explain the bytes.
