Oh Henry! Turn up the music with this littleBits project.
Give Philip Verbeek a bunch of LEGO blocks, a handful of littleBits, an MCU and a challenge, and there’s no over-the-top creation that the Maker can’t bring to life. Those of you who recall his earlier project — a pinball machine comprised of over 4,000 plastic bricks, six servos, five motors, an MP3 and Arduino — are sure to love his latest piece of work: Henry the LEGO Radio. Just like any conventional boombox, Verbeek is able to adjust the music’s volume, automatically scan forward and backward for stations, and manually turn the dial for new tunes. Take apart the LEGO bricks to reveal its inner workings and what you will find are a pair of synth speakers, a dimmer, a button, a few wires, a battery, a power module, as well as an ATtiny84 based Radio Bit board.
The Radio Bit can be used as a standalone device (with a power Bit) or in combination with other littleBits modules, as seen in this project. For instance, if paired with the cloudBit, users can even trigger weather forecasts and employ the radio as an alarm in the morning. This unit boasts three buttons (scanning, next song and mute), a couple of indicator LEDs, a digital FM transmitter, a low-power audio amplifier and an audio jack with an adjustable volume, which when connected to a set of headphones, doubles as an antenna. According to Verbeek, Makers can also extend the antenna via an antenna connector. Meanwhile, built-in memory will store the last radio station before powering down.
