1btn: Open Source WiFi Internet of Things Button0
Here is a smart button that can connect to the Internet to perform tasks. 1btn is an an open source device that can be used to send an e-mail, tweet, or complete a URL action (e.g. IFTTT). It does not make a continuous connection to the Internet, so it sleeps when you don’t need it. When your task is complete, the button’s multi-colored LED tells you the outcome.
The 1btn has a rechargeable battery life. The configuration interface can be accessed from a computer or mobile device. You can use this button to order a pizza, call a cap, lock or unlock doors, and other similar tasks.[where to get it]
