High-Tech LEGO Chapter 10: The Flickering Fireplace
Chapter 10 of “High-Tech LEGO” shows how to create dynamic lighting accents for LEGO models using the BlinkM, with construction of a fireplace as an example. Here’s a video of the fireplace.
I used the same type of lighting effect to decorate one of my favorite LEGO sets, the Tower or Orthanc. The light is installed to illuminate Saruman's palantir from below.
Chapter 10 mentions the use of a mist generator to enhance lighting effects, shown in use here in another room of the Tower of Orthanc. This mist is created by a Grove Water Atomizer (seeedstudio.com). A Grove Sensor Adapter, also used in Chapter 5 and Chapter 6, can be used to switch the mist on and off. Another use of the Grove Water Atomizer can be found in my blog post "LEGO Aromatherapy"
