Citizen, a German 43oh member, is currently building an intelligent coaster that notifies you visually and audibly about your drink. This is one of his first projects involving micro-controllers and he seems to be doing a good job so far, regularly updating his build log.
He’s trying to cram the following features into his design.
- TI TMP006 for contactless temperature sensing.
- Self powered design.
- A tiny buzzer for audible notifications
- A bi-color LED for visual indications
- Capacitive buttons to set the desired temperature for cold and hot drinks.
We normally forget to get to our drinks after a while. For us, the reminder feature would come in handy. How about you? Share your thoughts in the comments below or in Citizen’s build thread..
