HDD Speakers Complete

My hard drive speakers. These are 2 hard drives opened up with the read-write head connected up to a 10w stereo amplifier. Hard drives use electro-magnetics to move the read write head. The polarity of the current determines which way the head moves. In an audio signal the peaks and troughs are opposite polarities, meaning the head vibrates with an audio signal. This, combined with vibrating against the platters of the hard drive, make the sound.

I made a box out of acrylic for them and installed a volume control, 12vDC input, sound reactive neon strip and lots of LEDs (blue ones are flashing - the green ones on the HDDs flash because they are in series with the blue ones).

Anyone who says this is fake, it isn't ok? Try it yourself.

@griessinthewood I heard you fell out the womb backwards and bashed your head on satan's arse hole

@griessinthewood Lol you are such a troll. How would you like it if i called something you made ugly and crappy? And clearly other people don't find it ugly and crappy, or it wouldn't have been featured on Gizmodo and Hackaday and viewed by thousands of people.

I'm listening to this on my hard drive speaker, it's pretty loud (can't wait to install surround sound, it's the only time I'd buy a broken hard drive.)

Rather than the needle, I connected the two wires to the drive platter motor wires. The platter vibrates somewhat, and it gets hot. The needle doesn't move, but tis' alright.

The only problem is sometimes you'll hear a screech, metal on meal or a noise it can't play, or a weird frequency due to rattling...

Time, you've got it.

totally epic.

you would improve sound quality if you spun the disks slowly
