TOG: The Ultra-Small Bluetooth Enabled Button
Control your Bluetooth enabled devices with this open-source button that is only slightly larger than a micro SD card.
Tog can remotely control Bluetooth enabled devices such as smart phones, laptops, lights, locks and much more. When you press Tog it will wake up and communicate with your phone to execute pre-assigned actions. Tog ships with the ability to activate Siri/Google or take a picture on your smart phone with no apps required. Additionally, you may configure it to control or mute your music. The Tog design is open source so it can be modified to do whatever fits you.
The Tog base module contains a densely packed PCB assembly, battery, and modular expansion bus in a ultra-small plastic enclosure. The base module can operate standalone with no additional components required. The front of the Tog enclosure is transparent to allow the internal LED to be visible and allow the optical sensor to detect button presses.

Polarized magnets and alignment features ensure you can only assemble them right way. All connections are made between the modules with six spring pins to ensure long life and ease of use.
Simply stick the frame on any surface with the double sided tape and magnetically attach Tog to keep it in easy reach when its needed.
