We were excited to receive word yesterday that VTech's LUMENHAUS won the Solar Decathlon in Madrid this week. The competition, which asks participants from university teams to create a sustainable, self-sufficient house powered entirely by solar energy, only had invited two U.S. teams. LUMENHAUS took the overall prize as most efficient, and tied for first place in architecture, and took home several more prizes in other categories. Congratulations to the team! And they used a Spore True for their entry...

We get a lot of questions about doorbell transformers! Here we will attempt to answer the most common of them.
What is a doorbell transformer?
A transformer converts line-voltage to low-voltage (16 volts). In the United States, line-voltage 120 for most household wiring (this is what is running to your lights and outlets). In Europe and other parts of the world, line-voltage is 240. Any transformer that converts line-voltage to low-voltage will work as a doorbell transformer.
