We usually get Canon mods, but [polossatik] sent in some interesting Sony/Minolta lens modding work by [Shaocaholica], who’s been really been taking lens modding to a new level of quality. He picked up several old Rokkor F1.2 lenses and swapped parts around to make four decent lenses. Then he had [Pete Ganz] turn down some new mounts on his lathe. Finally, a quick round of epoxy to add a lens id chip activates the on board image stablization and focus confirmation. Be sure to check out the photo build log here.

Simple Digital Camera Spectroscope
[JC Doré] sent in this [english] interesting optics hack. The rubber grips are made from an old mouse pad, the springs for the clip were salvaged from zip drive floppy discs. A pair of old photo slide frames sandwich a diffraction grating slide. (Like this one) This simple mod allows the slide to be mounted to most cell phones, turning them into digital spectrometers.
Add On-board Light Metering To Your Nikon D40
Nikon didn’t build a light metering chip into the D40. That’s fine if you’re using one of their auto lenses with the on-board chip. [Matt] decided to add a sensor to his camera and try it out with his manual lenses. His writeup is a bit challenging to get through, but if you’re really into Nikons, you’ll make it. He had to tap into the ribbon cable inside the body, mount the extra hardware, and add an additional switch outside the body to allow the chip to be turned on and off. The extra sensor adds a bit of a step to taking the shot, but it’s the sort of thing that’ll become second nature pretty quickly.
D200 Hotshoe GPS Redux (el Cheapo Version)
It’s been a while since we talked about putting a GPS on top of a D200. [Rick] sent in his latest version. He used a nice 20 channel sirf III gps from spark-fun, a cheap D200 remote cable and a few parts to send the NMEA sentences down the wire. The biggest improvements include taking the $100 Nikon cable out of the mix and swiping power from the camera for the GPS board. All the info is there, but I had to seriously stare at his wiring instructions for a while despite the low parts count. I like to see actual circuit diagrams!
Super8 Automatic Film Scanner
[edocronian] sent in this interesting mindstorm hack. [Harri] had several Super8 reels that he shot during the 80s. His kids put together this mindstorm NXT transport mechanism, and he did the rest with linux. The lego’s pull the reel across an Epson scanner, and some linux hacks run the scanner, identify the frames, and reconstruct the film. Unfortunately, [Harri] didn’t release any of the software hacks he used to pull it off.
SLR Lenses On Your Digital Video Camera
Considering all the attention we give digital cameras, I wanted to find an interesting hack for those old school analog SLR cameras. (I spent a fair share of time behind one; I’m fond of the classic Canon AE-1) [Joshua] mated his Sony VX-2000e video camera with a Canon FD lens mount and created this monster. With the new lens mount, he’s got a full selection of lenses without the huge investment of specialized lenses.
Laser Camera Tracking
[ashish] is still having fun with his lasers. His latest hack is a dual laser based tracking camera. He mounted his camera to a simple parallel port controlled stepper motor. Essentially, if the camera loses track of either laser, it tracks to locate the lost edge of the object. I’d probably go with IR to reduce the chance of retina damage…
