LavaAMP Spectrum Analzyer


Is your dusty Lava Lamp just not cool enough anymore? What if you could make it bubble to the music? [Christian] and [Eric] managed to do just that.

No, they aren’t regular Lava Lamps. In fact, they look like oversize jam jars, but the video of them in action is pretty cool! They designed and built this system for the UIST 2013 Student Innovation Contest, and while there isn’t too much information on the actual build, the contest required everyone to use the exact same kit. The kit consists of 8 aquarium pumps, a PumpSpark controller board, assorted tubing and fittings and an optically-isolated serial interface for use with an Arduino or another kind of microcontroller. From there, it’s pretty easy to guess the rest — analyzing the audio, and timing the pumps according to the various levels.

Other competition entries of note include an awesome game of WaterPong, a Water Bottle Bagpipe, and even an Xbox H2O!

Stick around after the break to see the LavaAMP bubble to the bass.

Lava lamp centrifuge

Like many projects, this one started with a harmless question. “Will lava lamps work in a high-gravity environment such as Jupiter?”. Well, as it turns out, this harmless question was not so easily answered. The only real solution was to test and prove for sure. To do this, [Neil Fraser] built a centrifuge in his living room. At 10 feet across and roughly 50 kilograms, this is no small toy. The end with the lava lamp is set to pivot, so at a stand still, it is positioned vertically and at full speed it is positioned horizontally. The whole process is recorded on video for proof. So, does a lava lamp work in high gravity? Watch the video or read the article to find out.
