IMAGE PROCESSING DETAILS The OTS MGS evolved across three main iterations. The driving system requirement of these iterations was processing all image analysis and feedback within 100ms per frame, or 10fps. First Iteration: Image processing starts with the loading of a video frame into memory as an image file. The microcontroller then iterated through the […]

Researchers at Stanford University have demonstrated the acceleration of electrons through what they describe as an “On-chip integrated laser-driven particle accelerator”, detailed in a recent paper published in the Science journal. by Tom Abate On a hillside above Stanford University, the SLAC National Accelerator Laboratory operates a scientific instrument nearly 2 miles long. In this

When we first heard of [Ildar Rakhmatulin’s] plan to use OpenCV on a Raspberry Pi to detect mosquitos and then zap them with a 1 watt laser, we thought it was sort of humorous. However, the paper points out that 700,000 people die each year from mosquito bites — we didn’t verify that, but according to

Back in the 1980s, spectrum displays on audio equipment were absolutely must have, and the aesthetic came to define the era. This lingered on through the 1990s, and remains a cool look even to this day. [Arduino Guy] decided to put together such a display using a Raspberry Pi and a large LED display. The LED display in

How to use a portable laser projector to project on any surface interactively, using the Gravio Edge computing platform and Zigbee sensors. In this tutorial we learn how to set up a Raspberry Pi to connect to a PIR sensor using the Gravio Platform and then trigger various animated GIFs via CATT on to broadcast

Candy-sorting robots are in plentiful supplies on these pages, and with good reason — they’re a great test of the complete suite of hacker tools, from electronics to machine vision to mechatronics. So we see lots of sorters for Skittles, jelly beans, and occasionally even Reese’s Pieces, but it always seems that the M&M sorters

There is a romance to notions of a byegone age of DJing — driving a pair of Technics 1200s dwarfed on either side by the stacks, pumping techno bass through the laser-tinged darkness into a hungry crowd. Even if the reality of early evening Saturday wedding parties playing inoffensive crooners for the 50-somethings didn’t really

Scientists at the University of Stuttgart and the KIT succeed in important further development on the way to quantum computers. Quantum computers one day should be able to solve certain computing problems much faster than a classical computer. One of the most promising approaches is based on the utilization of single photons to carry and

Camera traps are a very common tool in wildlife conservation and research, but placing and pointing them correctly can be a bit of a guessing game. Something very interesting could happen just out of frame and you’d be none the wiser. The [Andrew Quitmeyer] and [Danielle Hoogendijk] at DINALABS (Digital Naturalism Laboratories) in Panama are
