It used to be that there wasn’t a problem on the average car that couldn’t be solved with a nice set of wrenches, a case of beer, and a long weekend. But the modern automobile has more in common with a spaceship than those vintage rides of yesteryear. Bristling with sensors and electronics, we’re at the point that some high-end cars need to go back to the dealer for even minor repairs. It’s a dark time for ...

Virtual reality and Augmented reality became essential technologies these days. They have an important role in making products much exciting and entertaining, especially in education. Recently, Livit Studios announced its new augmented reality book series “Imagina Book“. Imagina Books is an educational book series that converts the classic and traditional book into an interactive and 3d visualized. It provi ...

When you are out of your home for Christmas Holiday you can visualize the Temp and Humidity values by your smartwatch using ArduinoMKR1000. Things used in this project Hardware components Arduino MKR1000 × 1 DHT11 Temperature & Humidity Sensor (4 pins) × 1 Breadboard (generic) × 1 Jumper wires (generic) × 1 Software apps and online services Blynk Arduino IDE Arduino Web Editor Arduino Cloud Story I live ...

Photographic slides were popular in the middle part of the 20th century, but are long forgotten now. If you’ve found a handful in a dusty attic, you might consider sending them away to be digitized professionally, or using a flatbed scanner at home. [Bryan Howard] found himself with over 200,000 slides, however, so that just wouldn’t do. Instead, he endeavored to build an automated scanner of his own.  Like ...

After covering a few of his builds at this point, we think it’s abundantly clear that [Igor Afanasyev] has a keen eye for turning random pieces of antiquated hardware into something that’s equal parts functional and gorgeous. He retains the aspects of the original which give it that unmistakable vintage look, while very slickly integrating modern components and features. His work is getting awfully close to ...

Researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering IOF have developed a process that makes the production of a two-millimeter flat camera possible. Similar to the eyes of insects, its lens is partitioned into 135 tiny facets. The researchers have named their mini-camera concept facetVISION, following nature’s model. This mini-camera has a thickness of only two millimeters a ...

Light moving in vacuum is the fastest thing in the universe. Scientists have tried many times before to catch it on the move with some success. This time a new equipment built by Caltech scientists pulls down a mind-blowing 10 trillion frames per second, meaning it can capture light as it travels along, and also they are working to make it a hundred times faster. Understanding how light moves through a medi ...

Description A small PCB designed to attach to the backside of the FLIR Boson Thermal Camera. The PCB facilitates configuration of the camera along with capturing data to an SD card. This project is mostly an exercise in project-based learning. Instead of researching and reading about FPGAs, I want to create a project actually using them. Of course, this means that I'll likely get things wrong, but that's ju ...

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 ...
