Miniscule Intervalometer

August 6, 2010 by 43 Comments

Calling this intervalomemter small would be a glaring understatement. It’s tiny enough to fit inside the plastic cover for a 2.5mm jack for use with a Canon DSLR camera. We should point out that the image we put together is a bit misleading. The picture of the jack is version 1 of this circuit and uses an 8-pin SOIC chip. The board in the oval is version 2, with a PIC 10f222 SOT23-6 package making it even smaller than the original version.

This is used for time-lapse photography. When plugged in the chip draws power from the camera. Get this: it learns the timing interval by listening for the first two images. Once you’ve snapped the first two pictures the PIC will continue to take images based on that initial delay. Amazing.

DSLR Shoulder Holster With Follow Focus

[Erik] and [Jonathan Bergqvist] built this shoulder mount for a Canon 7D camera. It’s made from wood and it hooks over the top of the photographer’s shoulder with a handle for each hand. The left handle also controls the focus, using a similar method to the hardware store follow focus we looked at in January. Like it or not, you’ll love watching a master woodworker build this starting with un-milled logs. It’s all about having and knowing how to use the right tools.

2-axis Motion Timelapse Photography

January 7, 2010 by 6 Comments

[Milapse] picked up a motorized telescope base a few years ago. He’s using it to add motion to time-lapse photography. The base provides two-axis rotation controlled with a handheld keypad. Custom firmware and a bit of software allow for computer control. [Milapse] is pretty well-known in the time-lapse photography circles of the Inter-web. He’s posted a ten minute video explaining his setup and programming work for the hardware.

His use of a quality camera produces some nice video.However cost at $200 for the base, if you just want to play around with the concept you might want to stick to a webcam and LEGO setup.

Slide Digitizer

December 1, 2009 by 24 Comments

Remember slide shows? The ones that used a carousel projector and real slides? [Brian] wanted to bring his slides into the digital age but was spending far too much time scanning in the 35mm relics. He set to work and built a rapid slide digitizer using a projector, a DSLR, and a microcontroller.

His system centers around an AVR microprocessor, the ATtiny2313. Some DIP switches are used to set the number of slides to be scanned, and the timing for synchronizing the projector and the camera. Using two relays, the cable release for the DSLR and the remote advance pins on the slide projector are connected to the AVR. [Brian] used a macro lens and sets the focus, exposure, and f-stop manual. Once everything looks good the touch of a button quickly steps through the entire carousel at about 1 slide per second. A small video of the process is embedded after the break and his writeup has some comparison photos between a slide scanner and this setup.

Magic Lantern For Canon 5D

[Trammell] has released a new firmware for the Canon 5D Mark II DSLR geared toward film makers. The stock firmware was very limited on the audio side. This firmware adds features such as live VU meters, reduced audio noise, and crop marks for filming in different formats. The firmware is written in a manner that it can be extended fairly easily. Hopefully this will turn out to be as helpful as CHDK has been for point and shoot cameras.

Wireless Portable USB Tether

USB

[Pete] has put together a fairly simple writeup on building a wireless USB tether for your DSLR. He’s basically using a pair of USB wireless adapters and a battery pack. In his original version, he did some slight modification to the dock that powers the USB dongle, adding his own battery pack too. He notes that this whole project can be done without the effort he put into it, at a little more expense.  The only improvement we think would be nice would be a better way to package it to keep it out of the way while you shoot.

Cat5 Camera Flash Extension

January 17, 2009 by 11 Comments

extension

Network engineer [Mario Giambanco] recently purchased a cable to move his flash off camera. Unfortunately, it ended up way too short for his purposes. Instead of purchasing a slightly longer proprietary cable, he decided to employ what he had around him: a lot of cat5e cable and ethernet jacks. He cut the cable close to the center in case things didn’t work out and he’d need to repair it. His post on building the custom ethernet flash extension cable goes into heavy detail to make sure you get it right the first time. He’s tested it using both five and 50 foot pieces of cable with no apparent lag.

This isn’t the first time we’ve seen cat5 repurposed: composite video through cat5, vga cat5 extension, and cat5 speaker cables.
