Hackaday Prize Entry: Elephant AI

[Neik K. Sheridan]’s Automated Elephant Detection System was a semi-finalist in last year’s Hackaday Prize. Encouraged by his close finish, [Neil] is back at it with a refreshed and updated Elephant AI project.

The purpose of Elephant AI is to help humans and elephants coexist by eliminating contact between the two species. What this amounts to is an AI that can herd elephants. For this year’s project, [Neil] did away with the RF communications and village base stations in favor of 4G/3G-equipped, autonomous sentries equipped with Raspberry Pi computers with Go Pro cameras.

The main initiative of the project involves …read more

Reading Bingo Balls with Microcontrollers

Every once in a while a project comes along with that magical power to consume your time and attention for many months. When you finally complete it, you feel sorry that you don’t have to do anything more.

What is so special about this Bingo ball reader? It may seem like an ordinary OCR project at first glance; a camera captures the image and OCR software recognizes the number. Simple as that. And it works without problems, like every simple gadget should.

But then again, maybe it’s not that simple. Numbers are scattered all over the ball, so they have …read more

Matroid can watch videos and detect anything within them

 If a picture is worth a thousand words, a video is worth that times the frame rate. Matroid, a computer vision startup launching out of stealth today, enables anyone to take advantage of the information inherently embedded in video. You can build your own detector within the company’s intuitive, non-technical, web platform to detect people and most other objects. Reza Zadeh, founder… Read More Continue reading Matroid can watch videos and detect anything within them

Mythic launches a chip to enable computer vision and voice control on any device

 Hardware that responds to voice commands is already out there and probably in your hand or house right now. Whether it’s a smartphone, smart speaker or wearable, it has to connect to the cloud to deliver answers to your questions. Now, a startup called Mythic (formerly known as Isocline) is launching a chip and software that will change all that, putting voice control, computer vision… Read More Continue reading Mythic launches a chip to enable computer vision and voice control on any device

Objectifier: Director of Domestic Technology

[Bjørn Karmann]’s Objectifier is a device that lets you control domestic objects by allowing them to respond to unique actions or behaviour, using machine learning and computer vision. The Objectifier can turn on a table lamp when you open a book, and turn it off when you close the book. Switch on the coffee maker when you place the mug next to the pot, and switch it off when the mug is removed. Turn on the belt sander when you put on the safety glasses, and stop it when you remove the glasses. Charge the phone when you put a …read more

Arduino Video isn’t Quite 4K

Video resolution is always on the rise. The days of 640×480 video have given way to 720, 1080, and even 4K resolutions. There’s no end in sight. However, you need a lot of horsepower to process that many pixels. What if you have a small robot powered by a microcontroller (perhaps an Arduino) and you want it to have vision? You can’t realistically process HD video, or even low-grade video with a small processor. CORTEX systems has an open source solution: a 7 pixel camera with an I2C interface.

The files for SNAIL Vision include a bill of materials and …read more

Ping Pong Ball-Juggling Robot

There aren’t too many sports named for the sound that is produced during the game. Even though it’s properly referred to as “table tennis” by serious practitioners, ping pong is probably the most obvious. To that end, [Nekojiru] built a ping pong ball juggling robot that used those very acoustics to pinpoint the location of the ball in relation to the robot. Not satisfied with his efforts there, he moved onto a visual solution and built a new juggling rig that uses computer vision instead of sound to keep a ping pong ball aloft.

The main controller is a Raspberry …read more
