Hello! Here’s an English translation of my previos post. My English isn’t perfect so there might be some mistakes ;-).

Summer holidays are comming to an end, I have passed all september exams and now I am procrastinating doing some dumb things instead finishing two other, more serious projects ;-).
Here’s what polish AGH University of Science and Technology students do in their free time. I’d like to introduce my another, totally useless device – a musical floppy drives.

First attempt:

And now it’s time for the double:

How does it work?

It’s nothing new and it’s very simple. The sound comes from a magnetic head moved by stepper motor. To make a specific sound, head must be moved with appropriate frequency.
FDD has a simple interface – the description may be found for example [ HERE ]. To move the head you need to activate the drive by pulling the DRVSB0 or 1 (depends on the cable you have and the connector – notice the crossover on the FDD ribbon cable) pin low and then falling edge on STEP pin makes the head move one step in direction dependent on DIR pin state.
An ATMega microcontroller is generating those frequencies and it makes the drives play music.

Now it’s tome to call some older buddies (5,25′ or 8′ drivers) and make an orchestra!

  27. Eén van de eerste gecertificeerde QT instructeurs in

    Op deze site vindt u informatie over mij, Quantum-Touch, Quantum Basic Balance en mijn workshops
    in Nederland en Duitsland. Dit is geen site die vol staat met mooie
    en spectaculaire ervaringen; hoewel ik er in die jaren dat ik instructeur ben
    véél heb gehoord én meegemaakt. Tijdens elke workshop is het telkens weer genieten van de verbaasde gezichten van de cursisten.
    Door mijn ruime ervaring en omdat ik werk met kleine groepen gebeuren er elke workshop hele bijzondere dingen (o.
    a. dat iedereen gaat bewegen”)
    Mijn advies is: “Quantum-Touch moet je ervaren en beleven”

    Tevens vindt u hier ook doorschakelingen naar de officiële Amerikaanse site http://www.quantumtouch.com
    dát is de enige site met daarop ALLE therapeuten, instructeurs en workshops Quantum-Touch in
    Nederland en wereldwijd.

  34. Floppies are truly evil- i can remember mailing 3.5″ discs back and forth with my dad in the 1980’s- i guess that was the first kind of email!

  35. I just had a friend tell me to check out your videos on the Floppy Disk making music. I’m impressed! You have bridged music and technology in a special. After watching the videos, I also checked out „AGH University of Science and Technology” and was wondering, does your University keep up with technology in countries like America? Also, does your school have an exchange program? I’m going to look further through the site but anyhow, thanks for the IT entertainment.

  36. It’s a jungle out there 😉

  37. My partner and i still can not quite think that I could be one of those reading the important points found on your web site. My family and I are seriously thankful for your generosity and for offering me the chance to pursue this chosen profession path. Many thanks for the important information I acquired from your web page.

  38. I would like to use the ability of saying thanks to you for that professional advice I have constantly enjoyed viewing your site. We are looking forward to the commencement of my university research and the overall groundwork would never have been complete without surfing your website. If I might be of any assistance to others, I might be glad to help by means of what I have learned from here.

  43. Dzień dobry! Twój projekt z dwoma FDD podłączyć mnie. Nie wiem dlaczego.
    Ponieważ wielu ludzi chce powtórzyć, że należy znaleźć czas, aby ułożyć pełną elektronicznych i oprogramowania dla kontrolera.
    Dziękuję za dobry pomysł!

  44. Next step: store the music to play on the floppies themselves, and use the drives to read it and play it back. 🙂

  45. Plase publish electric scheme and pic software!
