[Samuel Sargent] built his own lens for making stacked macro images.This project, which was completed as part of his senior thesis, utilizes a Zeiss enlarger lens. The aperture ring was broken, making it difficult to tell how much light was being let into the camera. Instead of scrapping the whole thing he turned it around, making it a macro lens when combined with a few other parts. He’s used a Nikon PB-5 belows, a PK-13 extension tube, and a body cap to provide a way to mount the lens to his camera. A hole was added to the body cap using his Dremel, and a liberal dose of epoxy putty seals all of the gaps.
After the break you can see a couple of photos that [Samuel] made of bismuth. He estimates the sharpest focal length by taking a few test shots. Next he captures a series of images, moving the bellows slightly between each shot. Finally, this set is combined using Helicon Focus image stacking software. Maybe for his graduate thesis he can build a mechanized platform to move the subject automatically.

If you’ve ever tried to take pictures of yourself you’ll know that it can be a pain. It’s especially hard to get that perfect shot of your godly features when you’re out of breath from sprinting across the room. OK, yes, they have remote controls for that. But what if you lost your remote or you just don’t want to have to carry it? [LucidScience] put together a sweet, um, “hands free” alternative.
Essentially this hack emulates the IR signals sent by a Nikon remote, either to take a picture right away or to take time lapse photographs at regular intervals. We’ve seen a similar time lapse remote using an arduino before and a really thorough one using an AVR, but they don’t take the same approach as [LucidScience]’s design in terms of monitoring a microphone input for triggering. The project includes several status LEDs and adjustments for ambient noise and triggering, and it can be mounted to the camera body. We wonder how many of the Nikon’s features could be controlled using clap encoding, and how detailed your timing would need to be to have a kind of hand-made (get it?) pulsetrain syntax. You’d probably need to have world record clap skills.
Check out the demo vid after the break.

[Max] designed this circuit to add smart flash synchronization to his photography arsenal. He did this because ‘dumb’ TTL based flashes won’t play nicely with more sophisticated systems like the Nikon Advanced Wireless Lighting. By building a microcontroller into the mechanism, he’s added functionality for several different scenarios, ensuring that he’ll never again have problems with early flash triggering. Now that the kinks have been ironed out in the prototype, the code and hardware can be migrated over to whatever microcontroller suits you.
[Ross] put together a small package for use with time-lapse photography. The Nikon camera he’s using can snap a picture when it receives an IR command. [Ross’] solution connects an IR LED to an Arduino to generate this signal. The delay between frames is set with a potentiometer that is read in through the ADC. This is quite a bit less involved than the last solution we saw.
The unit consisting of an Arduino clone, a 9v battery, and the IR LED on a cable is easy to fit into a camera bag. He’s posted the code and we’ve embedded an example of his work after the break. An enclosure as well as time references around the potentiometer would complete this handy tool.

Earlier this year, Nikon released the Coolpix S1000pj, a 12 megapixel point and shoot with the usual features, including image stabilization, face recognition, etc. However, the S1000pj features a built in projector into the usual diminutive point and shoot footprint, and also comes with a remote for controlling the projector in display mode, or for remote shooting. iFixit has gotten a hold of the unit, and detailed the difficult teardown process, which included component desoldering to get the extremely compact system completely apart. It is also interesting to compare this setup to other stand alone pico-projectors we have covered.
[Aki]’s Nikon D2H did not come with an autofocus assist light. His other cameras have them, and he likes the feature, so he decided to hack one into his D2H. He wired into the AF system, so that his LED gets voltage when the shutter release is pressed half way. The circuit needs refinement though, he found that the light was staying on during shutter release and affecting his light metering. You can see the hack in action after the break.
