Hi.
I have been thinking about a project for a inexpensive digitizer for
the amiga. What I hope to do is put together a small CCD imager. The
reason I am posting this is to see if ther is any interest in a kit for
under $100. If there is enough interest I will try to get the thing
published in Amazing or Transactor, and make available circuit board,
parts, and some software. Like the Lucas Project.
Some specs:
Resolution - 192H x 165V
8 bits of grey (color is too expensive)
Interface - Serial Port
It of course will not be a realtime digitizer or be as easy to use as
Digiview, but with some care it should be able to digitize overscan HAM images.
Of course I welcome any comments and suggestions. I probably won't even have
a working prototype for a couple of months, but for now I am just seeing if
there is any interest in a CHEAP digitizer.
David.

David; Sorry man, someone beat you to it. Go to thy nearest store, check out "IMG Scan" by SunRize Industries, list $150. It consists of a CCD sensor connected to a printer head via a fiber optic cable, thereby turning an ordinary printer into a drum scanner. Resolution, whatever is the finest pixel rate on your printer. It's slow, but works.

I would love to get my hands on a digitizer for under $100. Given the Amiga's outstanding graphics capabilities it's a real shame there isn't a real cheap way to get images into the machine. I don't understand the point of digitizing HAM images with a gray-scale device. I guess you'd achieve color with a set of filters as does DigiView. Is that right? Even a monochrome only scanner (hand-held would be fine) would be superior to a camera based digitizer if it offered real sharp images. My main complaint about DigiView is the images just aren't sharp enough. It's OK for digitizing photographs for reproduction in newsletters, but I want something for digitizing line art. I want it to look really crisp and sharp, but I don't need color. The kind of stuff I'm thinking about could be colored with a paint program later. --Fabbian Dufoe 350 Ling-A-Mor Terrace South St. Petersburg, Florida 33705 813-823-2350 UUCP: ...uunet!pdn!jc3b21!fgd3

These are the two requirements of an IMG Scan installation according to SunRize's literature. I saw the IMG Scan running/working at the recent SF Amiga Festival in SunRize's booth. They had it installed in a 9-pin dot matrix printer, I believe it was some model of Star printer. The sensor was affixed to the printer's ribbon cartridge with some kind of aluminum TAPE. There was what looked like an 8x10 glossy picture of a portrait of a girl in the printer where the paper would normally feed and the IMG Scan was moving back and forth across the picture, rather slowly, one line at a time and the image was being fed to an Amiga and displayed on its monitor. The quality was quite good but as John said the process is slow since your printer is kicked into "graphics mode" during scanning. As far as the installtion, I wondered and asked about how precise an installation could be obtained by taping the unit to the ribbon cartridge or print head. The girl working the booth held up a small black metal clip and said "on some printers it can be installed with these too." I told her I had an Epson JX-80 (in which the print head moves but the ribbon cartridge doesn't since it's a full-width cart and that the print head had large heat sink blades surrounding it). She didn't know if it would install on a JX-80, which is, afterall, a rather common printer. So if the DeskJet has a print head which shuttles back and forth and you have access to it to tape or clip the IMG Scan to it and leave it that way during printer operation then it would work. If not, probably not. From what I remember of the DeskJet's case and configuration it *seems* unlikely to me that it'd work. -- | Harv Laser | SAC-UNIX, Sacramento, Ca. | | Plink: CBM*HARV | UUCP=...pacbell!sactoh0 | | "The human brain is the only computer made of meat" |

Nope, it won't , the HP deskjet has an internal printhead that is a INK jet style, it does not MOVE in the normal fashion. I don't think it will work.... **************************************************************************** Something is basically wrong with anyone who uses a disclaimer when they talk "My thoughts claim no responsibility for my body" tron1@tronsbox.UUCP Sysop, the Penthouse ]I[ BBS (201)759-8450 (201)759-8568

It would be interesting just as a hardware hack to build. I'd like to see it connected to the expansion port to see how to interface to it properly. Bear

Hmmm, this talk about a "scanner" that clips/tapes onto a printer's head has some possibilities that seem to beg exploration. For example: There is an optical sight (using fiber optics) mfd. by H-P that replaces the pen in an H-P plotter. It is used in conjunction with the manual controls on the keypad of an H-P plotter to send digitizing coordinates into one's computer over the serial port. The H-P plotters have a resolution < .001". Just THINK of the potential accuracy of scanning using an H-P plotter equipped with such such a 'read' head! One may have to "glue" odd-sized material (using the spray non-permanent adhesive that's akin to the material used on Post-Its (tm) by 3M) to a standard-size sheet used as a "carrier", but ...
