A new project has been published to the official Arduino blog this week providing insight into a new LoRa security camera and detection system that is capable of transmitting data when a trust parser is recognised. The system is also clever enough to ignore animals such as dogs that move into its field of view and will only trigger when it recognises a human figure. Watch the video below for a demonstration ...

As you might already know, Arduino is a compact microcontroller (programmable circuit board) and software combination that can be used as the basis for building a variety of electronic devices. While tech enthusiasts have been using Arduino to create fun and interesting inventions as a hobby, many entrepreneurs and corporate leaders haven't yet realized how this device can be used to create unique business ...

Now that digital imaging sensors are starting to become more freely available to the masses, all kinds of open source projects have been popping up that use them. Most of them are typically fairly limited to things like the Raspberry Pi or development boards like the Arduino and ESP32. But now, there is a new and pretty serious looking open source camera out there. It’s called the Octopus, it has interchang ...

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 ...

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 ...
