Well hello there.  For whatever reason, I'm unable to respond to your comment on my Musical Floppy Tutorial video (privacy settings perhaps?), so I'm posting here and hoping it gets to you:

Floppy drives, hard drives, and dotmatrix printers all have different interfaces you'll need to deal with.  The Moppy software can be used as a base, but you'll have to do a bit of your own engineering to get the Arduino to drive HDDs and printers.

HDDs use a conductive coil in a magnetic field to move the read head.  It's basically the same mechanism that speakers use, but it moves the head around instead of a cone.  Consequently, you can just hook an audio source directly to the HDD head coil, and it will act as a tiny speaker.

A dot matrix printer makes a noise each time one of its little dot-thingies (I'm sure they have a name, lol), punches the paper.  To get the printer to play music, you'll need to control the speed at which these thingies strike the paper.  E.g. 65.4 times a second would sound like the note "C".  I don't know enough about the interface to the printer to know how you'd accomplish that though, so you'll have to look elsewhere.

If you have any questions about the floppy drives though, I'm your man.  :)

Oooo, neat!  I love the two-tiered layout with the screen in the background.  Stereo recording seems to make a huge difference for floppy drives (I think it helps differentiate each part from all the noise).  Great work!

Thank you! I'm glad you like it! I agree, the stereo recordings sound a lot clearer.

For the first time in quite some time, a new floppy drive video! (I'm going to try to post a few more in the upcoming weeks, but no promises)

Hey there musical floppy aficionados!  Over the last couple days, I've committed a bunch of minor changes to the Moppy software codebase.  Most notably:
- No more RXTX library (switched to NRJavaSerial)
- No more "Swing Application Framework"
- Performance and pooling improvements
- Some new features to make it easier to (hopefully) play unedited MIDI files

I've also created a better floppy drive simulator so that it's easier for me to test out code changes without needing to have the drives assembled.  Which means it'll be much easier to add new features and accept pull requests.  Give it a try and let me know how things go!

I predict you run out of fuel before you can get too far... it looks rather heavy... let's see what happens-- ah, no engines at all then.  Okay.  =P  But wow, impressive!  I kinda want to try this someday now...

Oh man!  F/A-18 Hornet was my first flight sim back in the day.  GREAT game.

Hooray!  Closure!  
Looking forward to whatever's next (even if it's not a season 2).

Huh, this might be fun to try out next time I'm editing some music.  I like that it's free and open source, but my experience with other free MIDI editors has been a little disappointing.

3x Noobilator edited one of his pieces specifically for floppy drive for this video.

Up next: some more requested music and hopefully something a little bit classical.

+Sammy1Am Alright, I don't know anything about MIDI files so, I guess I'll try and find one, does it look like this: http://solmire.com/midi-info/129466/ghost-division-mid.html

I've seen some people complain about adding backing tracks to floppy music, but when the result sounds this good, I don't see how they could complain!

You'll just need some sort of MIDI editing software.  Each MIDI channel corresponds to one drive, and each drive can only play one note at a time.

It's still weird seeing your face and hearing your voice at the same time.... I somehow just associate that voice with blocky Minecraft people or Gary's Mod players and it doesn't seem right coming out of a human.

Musical floppy drives, and beyond!
Introduction
So YouTube made my YouTube account into a Google+ page.  It's a little weird, but I guess it'll be a neat place to put project-related posts and such.
