> **At Terrible Ideas Hackathon 2026, we frankensteined a Sainsbury's blender.**

The blender only works when you spin. To make the blender work, you need to download an Android app and pair your phone to the blender. Then, our app tracks your phone's IMU for continuous movement.

When your phone detectes a continuous spin of high enough speed, we broadcast a signal over bluetooth to an ESP32.

Since we didn't have any relays, we made the ESP32 move a servo arm to hit the 230V limit switch in the blender and activate it.
