Learn how to build an AC/DC interface for an Olympus E-510.
Unfortunately, Olympus didn't bother to make an AC/DC adapter for the Olympus E-510 camera. This typically isn't a problem as you can just tool around with a bag full of fresh batteries. It does become an issue if you decide to use your camera for time-lapse photos and don't want to replace batteries constantly during a long time-lapse sequence. Not only is replacing batteries a hassle, but it also shifts the position of the camera and makes the finished product not as smooth.
This project assumes you have a better-than basic understanding of DC electricity and some basic wood-working skill. If you have successfully built a circuit from a kit, know how to solder and are confident that you can cut wood without amputating your or your friends fingers, you should be OK.
If you have access to a laser cutter, you can have your plywood prototype in no time! If you don't, get your hobby knife and sand paper ready! This project also shows a great way to make 3d plywood prototypes.
You will need an AC/DC converter that can supply at least .5 amps (1 amp if you plan on shooting more than a picture/second) at at least 10 volts. Most variable voltage regulators need a supply voltage at least 2 volts over the set voltage to function properly. Check the spec sheet for your regulator.
To keep your camera safe, run your DC supply through a voltage regulator to ensure that your camera only gets between 6.8 and 7.2 volts. I suggest building the one shown below and dropping it into a box as it is handy to have an adjustable voltage regulator hanging around your bench. http://www.ladyada.net/library/equipt/diypsupp.html
If you can find an LBH-1 for a reasonable price ($60 here in Norway), you can skip this instructable and simply wire up the LBH-1 as shown on the page below. I strongly encourage you to use a voltage regulator between the AC/DC wall-wart and camera. The wall-wart adapter shown in the page below will *NOT*
provide a stable voltage. The selector switch simply sets an approximate range. http://www.pinetreecomputing.com/camctl_eseries_power.asp

Some things to think about before you start:
This project involves hacking your potentially expensive camera. With care and attention to detail, you should be able to create a nice AC/DC adapter without damaging anything. But as all hacking goes, you could wreck your camera and release it's magic blue smoke, start a fire, fall off the side of a bottomless cliff
, or make your dog implode. This worked great for me, but your mileage may vary.
