Now this post will be for some serious stuff involving video compression. Early this year I decided to make a lossless compression IP core for my camera in case one day I make it for video. And because it’s for video, the compression has to be stream operable and real time. That means, you cannot save it to DDR ram and do random lookup during compression. JPEG needs to at least buffer 8 rows as it does comp ...

Despite how good microscope you have, stand is still very important part of final assembly. And while there are many commercial ones made of cast iron, they might cost more than a microscope head itself. I decided to make stand from wildly available material laying around – it’s MDF (Medium Density Fiberboard). Advantages – stable over time if not exposed to water, dirt cheap, easy to process. Overview In g ...

Description Tiny, pill-sized cameras are frequently used in the medical field to visualize the gastrointestinal tract, particularly areas not readily accessible by bulkier devices. Increasingly, consideration is given to using these devices in patients who cannot tolerate, or are otherwise unwilling to undergo, a conventional colonoscopy. The possibility of displacing or augmenting these methods with tiny, ...

How many mundane devices upgrade to IoT because they let you monitor a single data point or a variable? That little nudge over the communication precipice allows you to charge 500% more. Now, if you are as handy as a Hackaday reader, you can throw a lazy afternoon at the problem and get the same effect from a “dumb” appliance. If IoT is as simple as getting a notification when your laundry is dry, or your w ...

The main objective of this project is to show how to interface a uCAM-II serial camera to 4Duino. uCAM-II is a highly integrated micro serial camera which could be controlled by any host that requires a video camera or a JPEG compressed still camera for embedded imaging applications. uCAM-II processes various features making it trivial to interface to a microcontroller. Following are the list of few feature ...

With surface-mount technology pushing the size of components ever smaller, even the most eagle-eyed among us needs some kind of optical assistance to do PCB work. Lots of microscopes have digital cameras too, which can be a big help – unless the camera fights you. Faced with a camera whose idea of autofocus targets on didn’t quite coincide with his, [Scott M. Baker] took matters into his own hands – foot, a ...

Smart traffic control for more livable cities. Story Abstract Traffic light control hasn't changed much in the last decades. Since IT changes everything, it's time to transform the traditional traffic control systems to smart ones that adapt and react to their environment. The story I was experimenting with Walabot, trying to make something with cats, because... Well because cats are fun. But then this happ ...

A wifi-connected high-precision camera slider, controllable from any web browser. Easily capture smooth sliding video shots or time lapses. Story My name is Ben Brandt, and I run a YouTube channel as a hobby to share my various DIY projects (like this one) as well as woodworking, metal work, and making things in general. In my quest to make better video, I wanted to be able to make long sliding/panning shot ...

At Coolest Projects 2018, we showcased the Wia platform with a facial recognition Ferris wheel! Story At Coolest Projects 2018, we showcased the Wia platform with a facial recognition Ferris wheel - if you're smiling, the wheel turns, and if you're not smiling, it stops. Today we're going to talk about how we built this project, and maybe you'll be inspired to build something like it! What we used Lego Ferr ...

Light propagating in a layer of scattering nanoparticles, shows the principles of diffusion - like tea particles in hot water. The deeper light is penetrating into the layer, the lower the energy density. Scientists of University of Twente’s Complex Photonics Group, however, manage to turn this falling diffusion curve into a rising one, by manipulating the incident light. More light energy inside an opaque ...
