Took a $8.99 Ikea lamp and hacked it with LEDs… this is just the first stage seeing how well the lamp works with the lights… It looks like there’s potential to create a kind of lava lamp program… anyone done anything like that?

A digital lava lamp would be fun. Have you tried out the FastLED noise examples?

Are you using two strips in there?

Looks a lot like (ok identical to) my old Holmo lamp. Have moved onto making my own. See https://photos.google.com/share/AF1QipN1GOCZ7Rdrj2meHII-6pWcAHGMYyv03Zjf5tfTRqmqhtdXc5gOEpS0Bc4GKPeLXg?key=UldaM29HaXhsUUY0c2xkRk82cUhyLThoeGd4ZXRR

Looks great! How many LEDs? What board you using? I built one with 126 APA102, Teensy 3.1, IR remote and audio input jack. No lava lamp pattern (yet), but collected a lot of patterns for it here: https://github.com/evilgeniuslabs/react

Have a look at http://www.hackerspace-ffm.de/wiki/index.php?title=Rundbunt_Mini (in German, Google Translate: https://translate.google.de/translate?sl=de&tl=en&u=http%3A//www.hackerspace-ffm.de/wiki/index.php%3Ftitle%3DRundbunt_Mini). Additional patterns linked at the bottom of the page.

I’m using 3 strings of 22 LEDs, each wired from bottom to top. I plan to have 3 separate sequences going. It’s driven using a Uno right now. I do think a lava-lamp type program would probably look pretty cool. I am also going to experiment with some programs that will look better given the partial diffusion of the LEDs (maybe some star-type twinkles). Right now I’m working on coming up with an algorithm where I can manage three strips separately but simultaneously. I should probably start a separate thread just for advice on best approach to that programmatically

I’m using lpd8806s in this implementation because I had them laying around, but I’d prefer to use 2812s because less wiring - and I believe the 8806s are more problematic and unreliable.

@Jason_Coon
really nice work! how did you do the audio input?

Thanks! I used the FFT from the Teensy Audio Library: http://www.pjrc.com/teensy/td_libs_Audio.html

This is the recommended audio input circuit: http://www.pjrc.com/teensy/gui/img/adccircuit.png

I just wired the headphone input jack directly to AGND and A8, without the recommended circuit. Seems to work well enough.

I had an almost identical lamp. I just tossed a couple Hue bulbs in it and thought it was cool but what you did is way cooler.

Exactly whats on my todo list, thanks for sharing! Could you show a photo of how you’ve attached the strip inside the lamp? Still couldn’t find a satisfying solution for that…
