Fresh hacks every day
Here's an automated setup that lets you create flat images of cylindrical objects. The example shown above takes a creamer and lets you see what the painted pattern looks like when viewed continuously. The image capture rig is similar to turntable photography setups that allow you to construct animated GIF files or 3D models of objects. The subject is places on a stepper motor which allows … [Read more...]
This beautiful build is a motion dolly for making time-lapse videos. It is at a point where you could consider it complete. After all, the segments featured in the video after the break look marvelous. But [Scottpotamas] has a few additions planned and it sounds like it won't belong before he accomplishes his goals. The build is a linear rail on which the camera rides. In the image above you … [Read more...]
Thermal imaging cameras, cameras able to measure the temperature of an object while taking a picture, are amazingly expensive. For the price of a new car, you can pick up one of these infrared cameras and check out where the drafts are in your house. [Max Justicz] thought he could do better than even professional-level thermal imaging cameras and came up with an absurdly clever DIY infrared … [Read more...]
Here's two photographic takes on the same subject, each with a different depth of focus. [Chaos Collective] came up with a way to make interactive still images that allow a user to adjust the depth of focus by clicking on different objects in the image. This was inspired by the Lytro camera which uses an array of lenses to take multiple pictures at once. Each of those images has a slightly … [Read more...]
Needless to say, there's a world of difference between the expensive DSLR cameras professional photographers use and the point-and-shoot models carried by commoners. One such difference is the ability to use slave flashes - a second flash set off to the side of the subject for better illumination. Most of these slave flash units are triggered when they see a bright light, or when the on-camera … [Read more...]
What do you do when you have a microcontroller you're trying to optimize? One method is using a debugger, but for AVRs and such that's not a very common technique. For lower-level electronics projects, it's nearly impossible, even. [Cnlohr] built a small Minecraft server that listens to in-game redstone circuits, but the performance of his real-world to block-world bridge wasn't what he hoped. He … [Read more...]
Last week we saw [Todd]'s solution to getting a tripod out-of-the-way when filming a few DIY videos. It's an overhead camera gantry that allows him to move a camera around his garage workshop without a tripod getting in the way. This weekend, he's back with a new and improved version. It's a vast improvement over his Mk 1 gantry system, and it much simpler to build, to boot. [Todd]'s new and … [Read more...]
