Make PCB’s with a Modified Lexmark Laser Printer
PCB manufacturing services are pretty cheap and fast nowadays. But imagine some kind of highly transmissible virus hits the globe, somehow the whole global economy shuts down, and you are stuck alone at home with nothing but a Lexmark laser printer. What can you do? Well, you can make your own PCBs! No paper involved. That’s exactly what Vítor Barbosa did by converting a Lexmark E460(DN) laser printer into a PCB making machine, not because of COVID-19, but instead, because of the price and delays of ordering PCBs in Brazil. Using a laser printing to make your own PCB like take some work, notably to strip the printer of unused parts such as the fuser and fit it with Arduino Nano or Pro Mini board, an aluminum guide, some resistors and more. The modifications are all explained on Hackaday.io, and this is not a new idea as the project was […]
UP Xtreme Smart Surveillance Combines Whiskey Lake SBC, Myriad X VPUs, and Video Management & Analytics Software
We’re seeing more and more computer vision products with built-in artificial intelligence accelerated features like face recognition or object detection including AI cameras, facial recognition systems, and AI NVR systems. It’s great as a consumer because of less frequent and more accurate alerts in security camera systems but more worrying as a citizen due to mass surveillance. But the trend is here to stay, and AAEON has just announced the UP Xtreme Smart Surveillance solutions powered by UP Extreme Whiskey Lake SBC with either an Intel Core i5-8365UE or Intel Core i7-8665UE processor, as well as two Intel Movidius Myriad X VPUs using OpenVINO SDK. The system also leverages Milestone video management software (VMS) and SAIMOS video analytics software. Based on the photo above, the hardware looks to be UPX-Edge Embedded Computer which we previously covered in details at launch last December. Instead of hardware, the focus of Up Xtreme […]
megaAI 4K AI Camera Board Features Movidius Myriad X VPU (Crowdfunding)
megaAI 4K AI camera board reminds me of Kendryte K210 based boards such as Maixduino used for computer vision for tasks such as object tracking or face recognition, but instead of just handling QVGA at around 15 to 18 fps, megaAI can supports inference at 4K resolution up to 30 fps. The tiny board can achieve this feat by leveraging the 4 TOPS of AI processing power delivered by Intel Movidius Myriad X VPU (Vision Processing Unit) while consuming only around 2.5 Watts. megaAI board specifications: AI Accelerator – Intel Movidius Myriad X VPU delivering up to 4 TOPS (Trillion Operations Per Second) Camera – 12 MP 4056×3040 Auto-Focus (8cm-∞) camera with 81 degrees horizontal Field of View (HFOV) Video RAW Output – 4K @ 60FPS or 12MP @ 30FPS (with USB3.1 Gen2 Host) Hardware Image Encoding – 12 MP JPEG encoding Hardware Video Encoding: 4K H.265 encoding at 30 […]
