Build A Stereo From an Old Hard Disk

An anonymous reader pointed us to an amusing little hack site that demonstrates how you can build a little stereo out of an old hard drive. Of course I don't need a stereo for I am a human beat box.

    2. Re:Commodore 64 music? by Awptimus+Prime · · Score: 3, Interesting

      I was wondering about the alignment issue.

      I ran a BBS on an old TRS80 with 4 floppies and was sending drives off over alignment issues every few months and that was from normal read/write accesses. Luckily, my local Radio Shack was cool and looking for support from the BBS community and ate the cost.

      Us TRS80 users had the tape motor relay as our audio toy. It was a simple coil relay that would make a very audible click when engaged or released. Though there was code to control the speed of access in BASIC, there were no limitations on what you could do with it in ASM. Apparently, the limitation was put in place to keep from destroying tape drives and the relay.

      I remember producing some really disturbing sounds, but ended up rigging the tape relay up to the power cable to my modem. With a small bit of code, a few wires, and raped cassette drive cable, it was relatively easy to turn the old RS 300 baud modems into auto-answer. Basically, splice the power cable to the modem, cut the cassette cable's drive motor and connect the two. Then splice the phone cable and connect the two live wires to the audio-in cable, then make a loop in ASM or BASIC that watches for a particular memory address value to jump from 7-10 to 250-255 for a few moments, then issue a MOTOR ON command and close the loop to power the modem who's switch is already flipped to ANS mode. Of course, this had limitations. I had to spend a lot of time tooling code for the BBS that would reduce the chances of a hung, dead connection (if the user hung up without logging out) as there was no actual carrier detection. My final solution was a TSR that would MOTOR OFF and reload the answer script if there was no activity for 2 minutes.

      That's another example as to why I always considered Commodites to be similar to what script kiddies of the mid-80's would have been, compared to the more traditional TRS80 hackers. The Commodites downloaded someone else's crap and ran it while us TRS80 ppl got out the soldering iron on a regular basis or learned ASM so all 64k of resources would be usable. :-)

      If you don't have the proper screwdriver handy, try drilling through the screws.

      Be careful when using a drill bit that's small enough to wear away a screw of the type used to secure hard drives. Because of their size, they have a tendancy to snap when caught on jagged metal. It's not nice having little pieces of drill bit bouncing into your face.

    ... or you will destroy your amplifier. Note that he says that you need to join the left and right channels together to get mono, if you are only making one speaker. Two low-impedance sources carrying different voltages......

    In any case it would work far better if the coil was kept within its original magnet, and the edge glued to a diaphragm. It is designed to work that way! If you were only wanting a woofer, you could simply attach the diphragm to the existing head arm, but don'y expect any response above a few 100 Hz.

I don't know what was up with quality assurance at Sinclair (except that Clive couldn't afford any), but the drives all ran at different speeds. So get yourself a dozen QLs (or ZX microdrives, or ICL One-Per-Desks), work out which notes they correspond to (relatively, no need for concert pitch here!) and then get programming! Starting and stopping the motors on the various machines will pump out da choons.

    When I first learned about this (on slashdot actually) I tried building a couple hard drive speakers for our university lounge. They actually worked pretty well, the only hard part being soldering to the thin, insulated wires (need to sandpaper down to reveal wire).

    We hooked it up to extra speaker outputs on the back of an ancient radio amp in our lounge so you can switch from regular speakers to hard drive speakers. The hard drives are actually wedged into corners of a wooden cabinet, and the real nice effect is because they cause the wood to resonate. Overall, the output is pretty loud!
