![]() ![]() Let’s face it: this world is pretty broken right now. ![]() Join us on Wednesday, April 13 at noon Pacific for the 2022 Hackaday Prize Hack Chat with Majenta Strongheart! Let’s take a closer look.Ĭontinue reading “Review: Vizy Linux-Powered AI Camera” → Posted in Artificial Intelligence, digital cameras hacks, Hackaday Columns, Raspberry Pi, Slider Tagged ai, camera, IR filter, machine learning, machine vision, raspberry pi, Raspberry Pi 4, tensorflow ![]() I found Vizy to be a highly-polished platform with a number of truly useful hardware and software features, and a focus on accessibility and ease of use that I really hope to see more of in future embedded products. I have always devoured anything that makes machine vision more accessible and easier to integrate into projects, so when Charmed Labs kindly offered to send me one of their newest devices, I was eager to see what was new. They also created the Pixy and Pixy 2 cameras, of which I happen to own several. Vizy comes from the folks at Charmed Labs this isn’t their first stab at smart cameras, and it shows. I have to say, it made for a very hacker-friendly experience. ![]() Even better, I did it all without installing a development environment, or even leaving my web browser, for that matter. I was running pre-installed examples written in Python within minutes, and editing that very same code in about 30 seconds more. Out of the box, Vizy is only a couple lines of Python away from being a functional Cat Detector project. I found it ridiculously simple to get up and running, and it was just as easy to make changes of my own, and start getting ideas. Vizy is a Linux-based “AI camera” based on the Raspberry Pi 4 that uses machine learning and machine vision to pull off some neat tricks, and has a design centered around hackability. The use of data centre waste heat is a novelty, as is in particular the siting of the data centre being dictated by the network.Ĭontinue reading “Ask Hackaday: Is It Time For Waste Heat And Cold Area Heating To Shine?” → Posted in green hacks, Hackaday Columns, Slider Tagged area heating, gas, heat pumps, waste heat It’s not uncommon at all for European cities to use district heating networks but they are normally supplied by waste incinerators, boilers, or combined heat and power stations. Joadl, CC BY-SA 3.0 ATĪ collaboration between a Finnish district heating network and Microsoft caught our eye because the location of a new data centre for the tech giant was chosen specifically to supply waste heat to the network, rather than releasing it to the environment. The Future is Cloudy A district heating plant in Vienna, Austria. Every alternative idea for energy supply is on the table, and with the parallel imperative of decarbonising the economy this goes beyond the short term into a future without so much need to rely on gas. Fortunately we’re watching the green shoots of an early spring here in the Northern hemisphere so the worst of the winter weather is behind us, but industrial customers can take no such solace from the season and will have to weather whatever price hikes are to come. It’s difficult to escape the topic of energy supply at the moment, with the geopolitical situation surrounding the invasion of Ukraine leaving the natural gas supply to an entire continent in jeopardy. ![]()
