I built this adapter in order to add larger battery capacity for prolonged time lapse shooting, it will work for adding battery hours to your camera or anything at a fraction of the price of commercial options.
Be aware that messing around with electricity can be dangerous to you and your equipment, if you are not comfortable with this, do not do this.
Step 1: What you need
- 1 battery for your camera. search on ebay or amazon and buy the cheapest one you can find, it doesn't have to work well it just needs to fit in your camera.
-2 DC to DC step down. Ebay again, just a few dollars. I used this one. http://www.ebay.com/itm/250954119681?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649
-3 Small enclosure for the step down.
-4 One DC power jack
-5 One DC barrel plug
-6 12" of 1 pair wire or a couple strands of hook up wire.
-7 Shrink tube
Multimeter <------ THIS IS A MUST!
