Perfect for all you home DJs, vinyl purists and electronic music producers - mounted in a spare drive bay in your PC is a minature record lathe, which "burns" audio into 5" vinyl or acetate blanks.

Whip out your little five-inch... record |
|
| |
Cool, except all the little vinyl turnings are going to make quite a mess of the stuff in your other bays. |
|
| |
Btw, my son saw this and thought it was cool too, so you probably have a market amongst the MP3 set. |
|
| |
they do make one, but i hear that it is rather expensive, like $5,000 or $13,000, i don't remember, sry. |
|
| |
Vinyl purists will note that records of olde were pressed from a master, not burned or etched as your idea suggests. |
|
| |
God, I love vinyl. If I could vote for this idea 10 times it wouldn't be enough. |
|
| |
Waugsqueke: Yes, this is true for large runs, but single
cuts are not unheard of in the DJ scene. Adds to the
cachet: "Yeah, genuine one off mate, sorted" |
|
| |
Further to this idea, and part-answer to DrCurry's
objections about vinyl scurf invading your PC: Perhaps
the burner could be similar to a CD burner, only with a
stronger laser. |
|
| |
The blanks could be a once-only thermoplastic, that
deforms under the heat of the laser, and then sets.
Rather than the binary, on-off modulation of the CD
laser, the beam is modulated by the continuously
varying analogue voltage of the audio signal. |

Oh, you'll hate me for this, UnaBubba: |

Re your Untrue on the LP-ROM: I once saw a UK electronic- musician's magazine from the early eighties which came with a flexi disk LP of reader demos etc. Track one *was* data, encoded as audio, and the magazine included a circuit diagram for plugging your turntable into the tape port of, I think, a ZX-81 or a Spectrum |
|
| |
If the plastic for the blanks was not thermosetting, you could make them re-writeable by running them through a hot roller dooby. |
|
| |
Don't leave them on the dashboard on a hot day, though... |
|
| |
That's it, I'm off to bed |
|
| |
//a ZX-81 or a Spectrum// |
|
| |
I picture this as more of an external device...perhaps the shavings then wouldn't be so much of a problem. A laser might be a cheaper approach, anything else would probably be grossly overpriced, as [cods] noted. |
|
| |
What a beautiful idea. I have long yearned to burn my minidiscs onto vinyl, even to flimsy cereal box flexidiscs, though I'm not sure why. Perhaps it's the fact that digital discs can 'go bad' all at once, but a good record player can plow right through scratches. |
|

Had both ZX-81 and Sinclair Spectrum (Spectrum Plus, no less - it had a weird hoojamaflip add-on that fitted on the bottom/back of the keyboard). Quite different: ZX-81 had piss-poor touch-sensitive "keys" marked out on it, whereas the Spectrum had real 3D rubber keys that you could actually press down and everything. Plus what Rods Tiger said about colour. Programming for my Spectrum as a little kiddie was where I first came across the word "cyan", and I've been rather fond of it ever since. Cyan... cyan... it's got a lovely ring to it. Not as flouncy as "cerulean", not as pompous as "azure". |
|
| |
Oh, and croissant for the idea. |
|
| |
outstanding idea, Bunsen. Run don't walk run & invest in the firm who'll make these. |
|
| |
An EZ Bake oven will do this. |
|
| |
What types of graphics did people manage on the ZX-81 I wonder? A 1K version wouldn't have much potential, but it would seem that with the expansion pack there would be some interesting possibilities ("officially" the ZX81 only supports a 32x24 text screen, using 2x2 "block" characters for graphics, but "officially" the Atari 2600 only supports two player objects, two missle objects, a "ball", and a single-color 20-pixel playfield which can appear identically on the left and right sides of the screen, or can appear with the right side reflected. |

Cods: the item you are describing is probably the
home lathe made by Vestax. It retails here for
$13,000 AU - about $6,000 US. The blanks are said to
have "90%" of the durability of commercial vinyl. |
|
| |
Hey [Rods] - you're the only person I know to have bought a Jupiter Ace - that was the one you had to program in FORTH wasn't it?
Re the ZX81 - it did have 1k of memory (on 4 256b chips!), like the ZX80 which I had. The ZX81 though was expandable to a gargantuan 16k. |

I have a SoundScriber Dictaphone. It takes green cellulose acetate records and embosses a groove into it. It only records in mono and it sounds pretty bad since I have no green records and instead use other plastics. I have tried a hard disk platter and have got pretty good sound from it. What would be cool would be to implement this in a PC Drive Bay and make it record in stereo. You could get 7-1/2 minutes on one side of a 4 inch record. Depending on how cheap you are, you could use anything from blister pack plastic to transparencies to the actual high fidelity green records. |

| |
Finaly, A use for those AOL CDs!! |
|
| |
Actually, cast-off CDs might not
be a bad medium for this. |
|
| |
Further thoughts on etching: |
|
| |
Coat discs with photoresist,
expose with UV laser, then etch in
PCB chemicals. |
|
| |
If using a laser to burn directly
into the disc surface, it would
possibly have to record at less
than 1x, to allow time for the
heating an cooling of the plastic. |
|
| |
Better to use the digital audio
stream directly to control the
power of the laser, than to convert
to voltage first. The fewer
conversions the better. |
|
| |
There was a drive a few weeks back to identify previous half-baked ideas that have materialised into the baked world... |
|
| |
(Just realised it isn't the same idea at all, oops - but still great) |
|
| |
Not to be nit-picky, but I believe when making a single record, the term is "Cut" rather than "burn." |
|
| |
My dad still "cuts" his DVDs, and says if it was good enough for records, it's good enough for CDs. |
|
| |
All good things come to those who wait |
