New Nikon Firmware Update Kills 3rd Party Battery Compatibility for Several Models

enel14

Nikon recently released a firmware update for its D3100, D3200, D5100, D5200, and P7700 cameras that maximized battery performance and allowed the camera to more accurately tell you how much charge you have left. But it seems there was an unintended (or maybe not so unintended) side-effect: third party batteries no longer work. Read more…

If you love everything about your GoPro camera except the anemic battery life and minimalist portability, say hello to the CagePro: a new system that allows you to attach a Canon SLR battery to your GoPro. Read more…

Building a DIY Battery Pack for Capturing Time-Lapses with a Point-and-Shoot

There are advantages to shooting time-lapses using a cheap point-and-shoot camera — for example, if it gets stolen, you’re not out thousands of dollars — but there is one particular challenge that is difficult to overcome: battery life. If you want your creation to cover any significant period of time, you need a way to keep the camera running.

The video above shows you one way to get around this problem if you’re using a AA-powered camera: just build your own DIY battery pack. Read more…

Researchers Tweak Camera Sensors to Boost Smartphone Battery Life

There’s no doubt about the fact that using the camera on your shiny smartphone is killing your battery life. But up until now, it seems like the only proposed solutions have been to work on the battery itself instead of looking at the camera.

Researchers at both Microsoft and Rice University think they’ve come up with a solution that will make your gadget’s camera far more energy efficient by focusing on the camera’s sensor and the power it uses.

Convert Your DSLR Battery Into a Power Supply Unit That Plugs Into Outlets

When Milan-based engineer and photographer Andrea Biffi needed a constant source of power for his Canon 40D in order to shoot time-lapse photos over many hours, he decided to save some money by going the DIY route. Biffi turned a defunct lithium DSLR battery into a power supply unit that can be used with everything from a wall outlet to a car battery.

You can do the same thing at home, but you’ll need a bit of engineering know-how to accomplish the hack.

Juice Up Your Camera Batteries with the Sun Using the Freeloader and CamCaddy

Solar chargers have been around for a while, but not a lot of them can handle the power needs of an SLR battery, and none that we know of can charge virtually any camera battery — until now that is. The Freeloader Pro and included CamCaddy can do both. Read more…

Photos of Alternative Batteries Created with Fruits and Coins

Lamp powered by 300 live apples, 2012

Portland, Maine-based photographer Caleb Charland (whom we featured before) has a fascinating new series of science-based photos that show various alternative batteries created using things like apple trees and stacked coins. The photo above shows an experiment in which he powered a lamp using 300 apples in a Newburgh, Maine-orchard.

He spent 11 hours sticking zinc-coated galvanized nails and bare copper wires into the apples in order to generate current using the fruit. Every 10 apples provide about 5 volts. The lamp was successfully lit by the apple power, but was so dim that the photograph required a 4 hour exposure!

Future Cameras May Have Lithium-Ion Batteries That Recharge in Minutes

What if the battery in your camera could be charged in the same amount of time it takes to microwave a cup of instant noodles? It sounds crazy, but that’s what appears to be headed our way.

Researchers at the Ulsan National Institute of Science and Technology in South Korea have figured out a way to drastically cut down the time it takes to recharge a lithium-ion battery — the same kind found in most digital cameras.

Make a Cheap Shutter Release for a CHDK Canon Camera with a 5V Battery

If you have a Canon compact camera running the Canon Hack Development Kit (CHDK) firmware, you can create a simple shutter release cable using some cheap components. The firmware causes the camera to snap a photograph anytime 5V is sent down a USB cable connected to the camera. You can do this using a USB cable (e.g. the one that comes with your camera), 5V battery, simple push button, and some kind of housing (a metal candy tin, for example). Oh, and you’ll need to be comfortable cutting up and soldering wires. Luo Bo Te over at kisstheasphalt has written up a tutorial on how to put everything together.

Nikon Recalls Some D7000/D800 Batteries Due to Overheating Issue

If you’re a Nikon D7000, D800, D800E, or V1 owner listen up, because Nikon has issued a voluntary recall on the rechargeable Li-ion EN-EL15 battery that’s used to power those cameras. Nikon discovered an overheating issue that can deform the outside casing of the cameras (at this point there have been only 7 confirmed cases worldwide) and is offering anybody with a battery whose 9th serial number digit is either “E” or “F” a free replacement. More details on both the problem and how to get your replacement can be found in Nikon’s service advisory.
