Wanted: Your Defective USB 1 Cable
I'm sure there's a hot market for these :D

I need a USB 1 cable to cannabalize for the wire needed for the motor used in the turntable I'm constructing. Basically I need the cord off a roached usb game contoller, Intellimouse, ect.

If you have one laying around, please let me know here, or by email

Never mind :rolleyes:

New plan.

Just let me know ...
... if you ever need any "vast off" or out of date USB 1.1 or USB 2.0 parts, cables or other ... I have been in the USB business since 1996 (pre iMac) and have a considerable "dead inventory" pile ...


DIYguy-builder 20th December 2006 10:49 PM

same here. I have a pile of those old cables that I have been holding onto because... you never know when you may need two dozen, out dated cables for something...

USB cables out of date?
Generally speaking, the cables that may only conform to the original USB 1.0 or USB 1.1 standards and Not Necessarily Obsolete. Quite often these cables will work just fine on the faster USB 2.0 systems' ports. Occasionally they may not work at the full speed of 480 mbps, but will work just fine at the lower speeds while connected to the slower or the faster ports ...

Don't throw 'em away! Don't sell 'em short! ... use 'em for mice, keyboards, printers, scanners, photo card readers, many still cameras, etc ... even some (lower performance) audio interface equipment ... and anything that is mechanical in nature like motor speed control, print and scan head movement, etc. ... Real world mechanical devices are seldom able to generate analog to digital electrical signals requiring the faster 480 mbps bandwidth. Example: no matter how fast you move your mouse, the data transfer rates to your computer seldom exceed the slowest USB speeds of ~ 1.2 mbps (actually closer to 9600 bps, max.) ... Keyboards and joysticks = same, same. The only USB devices that take advantage of the top USB 2.0 speeds are heavily buffered RAM/ROM memory devices like hard drives, CD and DVD readers and burners, the faster "flash" RAM drives ... AND High Performance Audio Equipment ... etc. (USB 2.0 ports all have dynamic impedence matching circuitry and dynamic data speed adjustment circuitry, so it is rare to find an "old" USB cable that will not work at all.)

FireWire IEEE 1394a and IEEE 1394b cables and ports use the same dynamic impedence matching and variable performance adjustability ... but it is rare to find a FireWire device or cable that does not perform at full speed, old or new.

(A mercinary announcment: ... and several more = these are all my web catalogs of digital and analog electronic parts = since 1996.)

... and if you're ever in need of one "right now" .. drop by one of your local second hand shops - goodwill, salvation army, etc. There is usually a box or clothes hamper back by the electronics junk filled with various cast offs and otherwise unmatchable cablry that comes in the back door. Usually fifty cents apiece.

bluebeard: " ... drop by one of your local second hand shops ..."

Good advise! Excellent sources. One is always suprised at how much very high quality electronics parts can be found in these "junk yard explorations" ... I have seen whole roof tops worth of solar water heater cells for the price of the weight of the copper !! ... and many, many perfectly usable piles of electronic parts including some very interesting and workable devices, sometimes for the price of the scrap weight plus a cost of a fuse! (Another interesting source is the dumpsters in the back of larger electronics manufacturing facilities [check with the plant managers first, they are usually very receptive to DIY types in search of "... another man's treasures"]).
