We’ve seen some work on diy digitizers before, but the one that [LP Rondeau] sent in is pretty sweet. It automates the process by advancing a slide projector carriage, blowing the slide clean with compressed air, and activating shutter release from a single controller. The images in this case have been shot in RAW (with a digital rebel ), and the setup allows immediate user review of the images – not to mention using the laptop for storage of all those huge images. The results of the shot and post processing are pretty good.

Digital Rebel XT(350D) IR Removal
[ash] wasn’t satisfied with these instructions, so he provided a complete how-to on gutting a Rebel XT to remove the glass IR filter. This one involves pulling everything down to the CCD. Once the IR glass is removed, it’s replaced with some high grade glass from Edmund Optics. If you’re into camera modding at all, and own a Digital Rebel, the reference links at the end of the how-to are worth a read.
Lazy Psp Player (automatic Woodchopper)
[Andrew]’s love hate relationship with his PSP is impressive. He used a webcam to watch for the appearance of the woodblock and used a small motor (probably serial or parallel actuated) to trigger the button on command. It’s a little silly, but it’s a good exercise for computer visual interaction.
Digital Camera IR Filter Removal
We’ve run across the idea of IR filter removal in the past. [Tony Z] pointed out this nice little how-to on removing the IR filter from a Canon a540 or a530 digital camera. I’m pretty blase about gutting electronics, but even I get a bit nervous about opening up recent model digi-cams. It’s so easy easy to jam sensitive gears… (don’t ask) Aside from my bad mini-dv experiences, the sub-200 6 megapixel platforms could make some interesting projects.

Canon DSLR Serial Control
We’ve seen diy shutter remotes before. Canon’s digital SLRs allow control of the camera over USB. Unfortunately they limited the exposure time to 30 seconds via USB control on some of them. To get around it, several (amateur) astronomers have built a serial interface to exploit the remote shutter control port normally used for accessories.
Canon Fd To Eos Inifinity Focus
Adapters to mount older fd mount canon lenses onto the newer eos cameras have been around for a while. There are some problems to solve. Because of the focal length, the fd lens could no longer focus to inifity and lose brightness(an f-stop). Rodolfo Novak modded his canon 55mm f1.2 fd lens for the eos mount by removing some vital parts(the attachment ring and the aperture ring). ?Now that the lens was closer, both infinite focus and the f-stop are back. He’s a bit short on the details, but it becomes clear if you look at an unmodified lens. Of course, to get the focus indicator working on a digital eos like my 350d, you need to add an af lens emulator circuit. If you don’t care about infinite focus, you could go a less invasive adapter.
Water Cooled CCD
Most ccd hacks today are based around modding webcams. Back in 2000, amateur astronomer ‘astroturtle’ built his own water cooled CCD camera. It was based on the long discontinued Texas Instruments TC245 CCD chip. Water cooling enhanced by a peltier junction is neccesary just to keep the chip cool enough during operation. The result? 378×242 pixels and a 2 second refresh rate.
