Intel’s Vision For Single Board Computers Is To Have Better Vision

May 26, 2017 by Mike Szczys 33 Comments

At the Bay Area Maker Faire last weekend, Intel was showing off a couple of sexy newcomers in the Single Board Computer (SBC) market. It’s easy to get trapped into thinking that SBCs are all about simple boards with a double-digit price tag like the Raspberry Pi. How can you compete with a $35 computer that has a huge market share and a gigantic community? You compete by appealing to a crowd not satisfied with these entry-level SBCs, and for that Intel appears to be targeting a much higher-end audience that needs computer vision along with the speed and horsepower to do something meaningful with it.

I caught up with Intel’s “Maker Czar”, Jay Melican, at Maker Faire Bay Area last weekend. A year ago, it was a Nintendo Power Glove controlled quadcopter that caught my eye. This year I only had eyes for the two new computing modules on offer, the Joule and the Euclid. They both focus on connecting powerful processors to high-resolution cameras and using a full-blown Linux operating system for the image processing. But it feels like the Joule is meant more for your average hardware hacker, and the Euclid for software engineers who are pointing their skills at robots but don’t want to get bogged down in first-principles of hardware. Before you rage about this in the comments, let me explain.

Submersible Robots Hunt Lice With Lasers

April 10, 2017 by James Hobson 54 Comments

De-lousing is a trying agricultural process. It becomes a major problem in pens which contain the hundreds of thousands of salmon farmed by Norwegians — the world’s largest salmon exporter — an environment which allows the parasite to flourish. To tackle the problem, the Stingray, developed by [Stingray Marine Solutions], is an autonomous drone capable of destroying the lice with a laser in the order of tens of thousands per day.

Introduced in Norway back in 2014 — and some areas in Scotland in 2016 — the Stingray floats in the salmon pen, alert and waiting. If the lice-recognition software (never thought you’d hear that term, huh?) detects a parasite for more than two frames in the video feed, it immediately annihilates it with a 530 nanometre-wide, 100 millisecond laser pulse from up to two metres away. Don’t worry — the salmon’s scales are reflective enough to leave it unharmed, while the pest is fried to a crisp. In action, it’s reminiscent of a point-defense laser on a spaceship.

It’s Not A Bridge, And Not A Tunnel. Or, Maybe It’s Both?

July 22, 2016 by Cameron Coward 94 Comments

The gist of the idea is to suspend an underwater tunnel from floating pontoons. By the time you finished reading that sentence, you probably already had a list of things in your head that seem to make this a terrible idea. After all, it does seem to combine the worst aspects of both underwater tunnels and bridges. But, the idea may actually be a good one, and it’s already being seriously considered in Norway.

Highlights From Robotic Shipwreck Exploration

OpenROV shared the results of their June 2016 underwater expedition to locate and robotically explore the wreck of the S.S. Tahoe, currently sitting at a depth of 150m in Lake Tahoe. Back in 1940 the ship was intentionally scuttled in shallow water, but unexpectedly slid to a much deeper depth. OpenROV used a modified version of their new Trident design to dive all the way down to the wreck and take a good look at things, streaming it over the internet in the process.

We previously covered the DIY research vessel that was designed and created as a floating base station for the ROV while it located and explored the wreck, and now the results are in! The video highlights of the expedition are below, as is a video tour of the ROV used and the modifications required to enable it to operate at 150m.

Shipwreck Exploration Vessels Fit In Minivan; Stream To Internet

June 2, 2016 by Donald Papp 2 Comments

Having to work away from the convenience of a workshop can be tough. But it’s sometimes unavoidable and it always means planning ahead. When the work area also happens to be 150m under a lake’s surface, it’s much more of a challenge – but it’s both doable and more accessible than you might think. To prove it, this DIY research vessel will be part of the robotic exploration of an underwater shipwreck. It is complete with an Ethernet bridge, long-range wireless communications, remotely operated underwater vehicle (ROV), the ability to hold a position, and more. The best part? It can all be packed up and fit into a minivan. We can’t put it any better than the folks at the OpenROV Forums:

In just over a week (June 6th – 9th), a bunch of people from OpenROV are going to attempt to dive a set of specially modified deep-capable ROVs to a 50m-long shipwreck at a depth of 150m below lake Tahoe. We’ll be using a deployment architecture that we’ve been perfecting over the years that involves a very small boat keeping station over the dive site while the rest of the people on the expedition run the mission from a remote location via long-range broadband radio. Since the mission control site will have an internet connection, we’ll be able to live stream the entire dive over the internet.

The purpose of the design was “to demonstrate that many of the capabilities one might think would require a large research vessel can actually be achieved with off-the-shelf parts that are more portable and much less expensive. […] There’s a lot to discover down there, and the technology readily available these days can allow us to explore it.” This mindset happens to wonderfully complement the kickoff of the Citizen Scientist Challenge portion of the 2016 Hackaday Prize.

For those times when your work can remain on solid ground, one method is to sidestep the entire issue of working away from the workshop by simply making your whole work area mobile like this incredible conversion of a truck trailer to a mobile lab.

Leg Mounted Beer Bottles For Underwater Propulsion

May 31, 2016 by Steven Dufresne 35 Comments

Sitting on the beach, finishing off a beer one day, [Rulof] realized that if he put a motor in the beer bottle with a propeller at the bottle’s mouth, he could attach the result to his leg and use it to propel himself through the water. Even without the added bonus of the beautiful Mediterranean waters through which he propels himself, this is one hack we all wish we’d thought of.

These particular beer bottles were aluminum, making cutting them open to put the motor inside easy to do using his angle grinder. And [Rulof] made good use of that grinder because not only did he use it to round out parts of the motor mounting bracket and to cut a piston housing, he also used the grinder to cut up some old sneakers on which he mounted the bottles.

You might wonder where the pistons come into play. He didn’t actually use the whole pistons but just a part of their housing and the shaft that extends out of them. That’s because where the shaft emerges from the housing has a water tight seal. And as you can see from the video below, the seal works well in the shallow waters in which he swims.

Devilishly Advocative: Microsoft Heats Ocean; Builds Skynet’s Safe Haven

February 3, 2016 by Mike Szczys 79 Comments

Have you heard that Microsoft is testing underwater data centers? On the surface (well, actually on the ocean floor) it’s not a bad idea. Project Natick seals a node of servers in a steel pipe for an undersea adventure planned for at least 10 years. The primary reason is to utilize cold ocean temperatures to keep the machines cool as they crunch through your incessant Candy Crush Saga sessions.

Passive cooling is wonderful, and really drops the energy footprint of a data center, albeit a very small one which is being tested. Scaled up, I can think of another big impact: property taxes. Does anyone know what the law says about dropping a pod in the ocean? As far as I can tell, laying undersea cabling is expensive, but once installed there are no landlords holding out their hands for a monthly extraction. Rent aside, taking up space with windowless buildings sucking huge amounts of electricity isn’t going to win hearts and minds of the neighborhood. Undersea real estate make sense there too.

But it’s fun to play Devil’s Advocate, and this one immediately raised my eyebrow. I read as much Sci Fi as time allows, and am always interested to see which authors are registering the best technology predictions. This is the second time in short order that I turn to [William Hertling’s] work. Back in November, Google announced a project to add predictive responses to Gmail. This parallels the premise of [Hertling’s] Singularity Series which begins with Avogadro Corp. Another major point in that novel is the use of offshore data centers.
