I've dismantled a cheap & nasty fax machine. Out of this I've extracted a Dyna Image scanning unit, CFL illumination, 7 wires.

DIY 130-megapixel camera built with a scanner

Gear seeking?

 Hi all instructables dudes,  I have a scanner made by Pimax (model name Profi 9600) drived by a SCSI adapter. Is old model (1999) but is very good and reliable too. The problem now is i have a broken plastic gear that drives the belt for doing the passes during the scanning. Without this small gear the belt is dead and the scanner too. Has anyone this small gear from his old and non using scanner? If not please inform how can i reuse this scanner because everything else on it works fine. Can i modified it to a manual shifted scanner? This scanner is ONE pass so can I put any external case hand gear to move the lamp? Please give some ideas.....anyone is acceptable.... thank you all in advance! Agis

How can I make a scanner camera with a dead flatbed scanner?

I found this link: and it just so happened that my printer/scanner had just died. It still powers on, but the driver software completely refuses to see it. So I figured I'd try to make one.- I guess one of the circuit boards in my scanner is dead, so I won't be able to use the scanner's electronics to drive the CCD. I did manage to pull it out unharmed though. It connects via a 12-pin ribbon cable, so I figured I'd just drive it via a couple of parallel ports, or maybe a microcontroller if I get bored enough to learn how to use them. I have no idea which pins on the ribbon cable do what though, any idea where I'd go to find this? (The printer is a Dell Photo 944.)- The person in the link above seems to have a different kind of CCD which is much smaller than mine. Mine is long and thin (and like every other scanner CCD I've seen except that one); I have no idea how I'd get a lens on it. Any thoughts?

Hacking Flatbed Scanner Components

I am currently working on a project which was going to use a scanner to acquire an image. The scanner is/was an HP 6200C. When I was trying to modify the scanner I accidentally broke the lamp, but was then excited to discover [what I believe is] a linear photodiode array which functioned as the detector. (I also found some cool mirrors and a focusing lens inside.) This photodiode array could be very useful to my project.  This scanner interfaces with my computer through USB, and refused to work after I unplugged the lamp. I figure a resistor may trick the circuitry into thinking the lamp is still attached, but I no longer require the moving parts of the scanner at all; I only want the photodiode array and a way for it to interface with the computer, preferably giving either a "single line" type image or a "single really thick line" type image. (Basically I just need intensity and location of signal. If the received data is a full image, I can reduce it to what I need.) Does anyone have any experience or suggestions for me? I have uploaded a few pictures of the relevant circuitry and can add more upon request. Update: After further research, I've determined that it is not a photodiode array but a linear CCD.

Coordinates of an object on a passive image

I have a few questions regarding a project I'm working on. I need some terms so that I can look it up via Google. I have a map (picture) of a city that is printed on a wooden table. When I move an object directly over it I want to know the coordinates of the object on the map. And also the angle of the object on the map. I thought a sort of a scanner is the best solution. That recognizes the part which it scans (part of the map) and translate this to the coordinates and angle. Does somebody know how this technology is called (and maybe a few links to guide me in the right direction)? Or does somebody else has a better idea how this can me realised? Thanks in advance!

alternative stepper motors?

As a side note, I have a very limited understanding of IC function, think of me as having lived a purely analog lifestyle.

Powering a ccfl panel from a broken laptop screen?

All i want to know is how much power do i need to put into the inverter (if i can use it) and where do i put the wires? i also took apart some scanners to try and use their inverters, but it seems that all the scanners i have all have inverter looking boards built into them and work off ribbons so i don't know how to power these either.

reusing scanner lamp w/o heavy duty adapter?

I've been trying to do something similar to these!/I want the lamp to work without a heavy duty ac to dc adapter, but it looks like there's no practical power cord that has low enough voltage. I've tried using a basic voltage converter ( ) set at 12 volts, but the bulbs don't light.Does anyone know if there's a way to do this without the giant adapter, or if there's a way to light the bulbs using a USB connection? I've looked online, and the only thing I've seen is this: but they're using a male molex connection. I'm just looking for a plug that's a little more practical: an electrical outlet being my first choice, a usb port being my second.Thanks!

HP Scanjet 2200c -- how can I make it work on my new computer?

This  is an older scanner, but there was nothing wrong with it when my old computer broke down, and I used it a lot.  HP does not provide updates for older scanners. I have heard that it can be updated without HP's help, but I'm not that experienced. I have installed the scanner program--still have the program CD-- but when I try to use it, it tells me that the scanner is being accessed by another program.  It also tells me that it has stopped working.

Can I turn my digital SLR into a large format grid scanner?

I am an artist and want to make prints of my large paintings. I have been using a flat bed scanner to scan artwork in multiple chunks and "stich" them together in photoshop thus far with success. However, using over 2 separate chunks, it is hard to get lines and shapes to line up. Also, the larger the image, the more akward it is to try to get the work on the scanner. So i was thinking of some way to use a digital camera to create the same affect. Ideally, the camera would be mounted to a rig floating over the painting and scan it into chunks. I can manually do the "stitching" but it would be sweet if some software would do it for me ;) Anyone know of anything like this? I have a very low tech version in mind, but would love a sort of automated plotter setup.
