Raspberry Pi Gameboy

Soulskill posted yesterday | from the what's-old-is-new dept.

Classic Games (Games) 45

An anonymous reader writes: An enterprising hacker took on a project to rebuild a broken Gameboy using emulation software, a Raspberry Pi, and a few other easily-obtainable parts. The result: success! The hacker has posted a detailed walkthrough explaining all of the challenges and how they were solved. "Using a Dremel, I cut out a most of the battery compartment as well as some posts that on the case for the LCD that would no longer be needed. Doing so, the Pi sits flush with the back of the DMG case. ... The screen was the first challenge. The screen runs off 12V out of the box which wouldn't work with the USB battery pack. The USB battery pack is rated at 5V, 1000mAH so the goal was go modify the screen to allow it to run at 5V. ... I finally got it to work by removing the power converter chip as well as soldering a jumper between the + power in and the resister on the top right."

SRI/Cambridge Opens CHERI Secure Processor Design

Hardware Hacking 59

An anonymous reader writes with some exciting news from the world of processor design: Robert Watson at Cambridge (author of Capsicum) has written a blog post on SRI/Cambridge's recent open sourcing of the hardware and software for the DARPA-sponsored CHERI processor — including laser cutting directions for an FPGA-based tablet! Described in their paper The CHERI Capability Model: Reducing Risk in an age of RISC, CHERI is a 64-bit RISC processor able to boot and run FreeBSD and open-source applications, but has a Clang/LLVM-managed fine-grained, capability-based memory protection model within each UNIX process. Drawing on ideas from Capsicum, they also support fine-grained in-process sandboxing using capabilities. The conference talk was presented on a CHERI tablet running CheriBSD, with a video of the talk by student Jonathan Woodruff (slides).

Although based on the 64-bit MIPS ISA, the authors suggest that it would also be usable with other RISC ISAs such as RISC-V and ARMv8. The paper compares the approach with several other research approaches and Intel's forthcoming Memory Protection eXtensions (MPX) with favorable performance and stronger protection properties.
The processor "source code" (written in Bluespec Verilog) is available under a variant of the Apache license (modified for application to hardware). Update: 07/16 20:53 GMT by U L : If you have any questions about the project, regular Slashdot contributor TheRaven64 is one of the authors of the paper, and is answering questions.

ClockEndGooner writes Looking for a 3-D printer to help you out with a home project or two? If you're in one of the 12 pilot program areas in the U.S., stop into Home Depot to take a look at and purchase a MakerBot 3-D Replicator printer. "...The pilot program will offer the microwave-sized MakerBot Replicator printers, priced at $2,899, for sale, as well as the smaller Replicator Minis, which list for $1,375. 'This will open up the whole world of 3-D printing to people who wouldn't otherwise know about it—like moms and dads, electricians, contractors and DIY-home-improvement folks,' said MakerBot chief executive Bre Pettis. 'It's a good match.'"

Chinese Company 3D Prints a 2-person Boat

China 5

First time accepted submitter Bob768 writes A Chinese company, Sanya Industrial Innovation Design Center, has 3D printed the very first one piece boat. The boat will seat two adults comfortably, and measures 2 meters in length by 0.8 meters wide, and weighs approximately 35 kg. "One interesting fact about the 3D printer used to create this boat, is that it doesn’t require spools of filament, but rather can be fed with raw materials, in the form of pellets or ground up thermoplastics."

New Raspberry Pi Model B+

samzenpus posted about two weeks ago | from the latest-and-greatest dept.

Upgrades 202

mikejuk writes The Raspberry Pi foundation has just announced the Raspberry Pi B+. The basic specs haven't changed much — same BC2835 and 512MB of RAM and the $35 price tag. There are now four USB ports, which means you don't need a hub to work with a mouse, keyboard and WiFi dongle. The GPIO has been expanded to 40 pins, but don't worry: you can plug your old boards and cables into the lefthand part of the connector, and it's backward compatible. As well as some additional general purpose lines, there are two designated for use with I2C EEPROM. When the Pi boots it will look for custom EEPROMs on these lines and optionally use them to load Linux drivers or setup expansion boards. Expansion boards can now include identity chips that when the board is connected configures the Pi to make use of them — no more manual customization. The change to a micro SD socket is nice, unless you happen to have lots of spare full size SD cards around. It is also claimed that the power requirements have dropped by half, to one watt, which brings the model B into the same power consumption area as the model A. Comp video is now available on the audio jack, and the audio quality has been improved. One big step for Raspberry Pi is that it now has four holes for mounting in standard enclosures.

Mars 104

coondoggie writes Taking a page from NASA's rocket powered landing craft from its most recent Mars landing mission, the European Space Agency is showing off a quadcopter that the organization says can steer itself to smoothly lower a rover onto a safe patch of the rocky Martian surface. The ESA said its dropship, known as the StarTiger's Dropter is indeed a customized quadcopter drone that uses a GPS, camera and inertial systems to fly into position, where it then switches to vision-based navigation supplemented by a laser range-finder and barometer to lower and land a rover autonomously.

15-Year-Old Developing a 3D Printer 10x Faster Than Anything On the Market

New submitter jigmypig writes: One of the main issues with 3D printers today is that they lack in one area; speed. A 15-year-old boy named Thomas Suarez is developing a 3D printer that he says is the most reliable, most advanced, and faster than any 3D printer on the market today. In fact he claims it is 10 times faster than any 3D printer ever created. "There's something that makes me want to keep going and keep innovating," he says, laughing at being asked if he'd be better off outside climbing trees or riding a bike. "I feel that my interests will always lie in technology. Maybe I should go outside more but I just really like this stuff."

ganjadude (952775) writes "I stumbled upon this little scoop and thought the Slashdot crowd would be interested in. The new kid on the block, known as the HummingBoard can handle faster processors, more RAM and will fit the same cases for the Pi. Also, you can expand the memory and the CPU is replaceable! The low end model starts at $45 and the high end costs $100. So tell me guys, what are you going to do with yours?" $45 model is a single core iMX6 (an ARMv7) with 512M of RAM, the $100 model has a dual core i.MX6 with 1G of RAM. Full specs.

Radar Changing the Face of Cycling

Transportation 235

First time accepted submitter Franz Struwig writes "MAKE Magazine has a great review of a bicycle radar product — showing off some of the early prototype innards: "The latest version features a 24 GHz radar antenna — high enough to resolve more targets and small enough to fit on a bike — an ARM processor, and Bluetooth LE to communicate with the front unit. The radar creates a doppler map, and recognizes not only the vehicle, but how far away it is and how quickly it’s approaching. It communicates this to the cyclist by a system of LEDs, and to the car by increasing the rate at which the tail light blinks as the car gets closer."

Chinese Company '3D-Prints' 10 Buildings In One Day

China 118

Lucas123 writes: A company in China has used additive manufacturing to print 10 single-room buildings out of recycled construction materials in under a day as offices for a Shanghai industrial park. The cost: about $5,000 each. The company, Suzhou-based Yingchuang New Materials, used four massive 3D printers supplied by the WinSun Decoration Design Engineering Co. Each printer is 20 feet tall, 33 feet wide and 132 feet long. Like their desktop counterparts, the construction-grade 3D printers use fused deposition modeling (FDM), where instead of thermoplastics layer after layer of cement is deposited atop one another. The cement contains hardeners that make each layer firm enough for the next. Yingchuang's technique builds structures off site in a factory one wall at a time. The structures are then assembled onsite. The technique is unlike U.S.-based Contour Crafting, a company whose 3D printing technology to form the entire outer structure of buildings at once, The Yingchuang factory and research center, a 33,000 square foot building, was also constructed using the 3D printing manufacturing technique. It only took one month to construct.

Project Tango is part of Google's Advanced Technology and Projects group (ATAP), which Wikipedia says was "...formerly a division of Motorola." Tango's goal is "to give mobile devices a human-scale understanding of space and motion." We humans and our forebears have spent millions of years learning to sense our surroundings, not as a set of static 2D images, but in 3D with motion. This YouTube video starring Johnny Lee, the Tango project lead Tim interviewed at Google I/O 2014, gives you some decent insight into Project Tango's goals -- in addition to our video, that is.

Nathan Myhrvold's Recipe For a Better Oven

Soulskill posted about three weeks ago | from the i-don't-need-twitter-on-my-fridge-but-a-smarter-oven-would-be-nice dept.

Technology 228

Tekla Perry writes: We cook our food today using technology invented to bake bricks. We can do a lot better. Nathan Myhrvold explains what's wrong with today's ovens and challenges oven designers make them better. He says, "Oven designers could do a lot to make ovens heat more evenly by taking advantage of the different ways ovens transfer heat at different cooking temperatures. At 200 C or below, convection moves most of the heat. But at 400 C, radiant energy starts doing a fair amount of the heat transfer. At 800 C, radiation overwhelms convection. Why couldn't we have an oven designed to cook primarily by convection at low temperatures that switches to radiant heating for high-temperature baking? ... The shiny skin of raw fish reflects heat, but as the skin browns, it reflects less and less energy. That’s why food under a broiler can seem to cook slowly at first and then burn in the blink of an eye. But technology offers a fix here, too. Oven designers could put optical sensors in the oven chamber to sense the reflectivity of the food, and then the oven controller could adjust the heat automatically or at least alert the cook as the surface browns. And a camera in the oven could feed to a color display on the front panel, giving the chef a clearer view of the food than a small window in the door can. Indeed, a decent optics system could allow designers to dispense with the glass in the door altogether, reducing the gap between the hottest and coolest corners of the oven and obviating the need to open the door and rotate the food midway through cooking.

EDSAC Diagrams Rediscovered

United Kingdom 37

mikejuk (1801200) writes Due to its importance in the history of computing, the UK's Computer Conservation Society embarked on a 4-year project to build a replica of EDSAC. The main challenge facing the team of volunteers who are working on the rebuild is the lack of documentation. There are almost no original design documents remaining so the rebuild volunteers have to scrutinize photographs to puzzle out which bits go where. However, three years into the project, a set of 19 detailed circuit diagrams have come to light and been handed to the EDSAC team by John Loker, a former engineer in the University of Cambridge Mathematical Laboratory. "I started work as an engineer in the Maths Lab in 1959 just after EDSAC had been decommissioned. In a corridor there was a lot of stuff piled up ready to be thrown away, but amongst it I spotted a roll of circuit diagrams for EDSAC. I'm a collector, so I couldn't resist the urge to rescue them. " In the main, the documents confirm that the team has been correct in most of its re-engineering assumptions, but the drawings have thrown up a few surprises. The most significant discrepancy between the original and the reconstruction that the papers reveal is in the "initial orders" (boot ROM in modern terminology). In the absence of fuller information, the reconstruction team had considered and rejected one possibility which was in fact the one that was used by the original engineers. That will now be rectified in the reconstruction, which is due for completion in late 2015.

On the Significance of Google's New Cardboard: An Idea Worth Recycling

timothy posted about three weeks ago | from the off-the-shelf dept.

Cellphones 42

Last week at Google I/O, the company introduced Cardboard, its cheap-and-cheerful (it's made of cardboard, after all) approach to nearly instant VR viewing. It's no Oculus Rift — lacking the Rift's connection to a powerful backend PC, it can't do the same heavy lifting. In fact, it looks sort of like a prank, and the announcement at I/O that everyone at the conference would be getting "a piece of cardboard" drew a lot of chuckles. Gigaom argues that it's nonetheless extremely valuable, because it makes immersive viewing easy and cheap for anyone with a fairly capable smartphone — a pretty satisfying experience in itself, and a good taste of what even higher-end viewers can bring. "In addition to the Cardboard app," writes an anonymous reader, "Google has pushed out an updated version of Google Maps which includes a VR mode for Street View." And if you weren't blessed with an I/O pass, and aren't sure about your skills cutting one out of a pizza box, note that you can buy a kit for about $25, including the RF tag that will tell a phone to fire up the Cardboard app. (The linked article says an aluminum version is in the works from at least one company; I'd like to see one in corrugated plastic — strong but light — and with connection points for a headstrap.) If you've made something similar (or would like to), what would you improve in the design or feature set? (Look soon for a video introduction to Cardboard with Google VP Clay Bavor, too.)

Intelligent Autonomous Flying Robots Learn and Map Environment As They Fly

timothy posted about three weeks ago | from the learning-as-they-go dept.

AI 37

An anonymous reader writes with this story about a machine-learning project out of the UK's University of Sheffield: Using simple drones the researchers have created automatic-control software that enables the "flying robot" to learn about its surroundings using a camera and an array of sensors. The robot starts with no information about its environment and the objects within it. But by overlaying different frames from the camera and selecting key reference points within the scene, it builds up a 3D map of the world around it. Other sensors pick up barometric and ultrasonic data, which give the robot additional clues about its environment. All this information is fed into autopilot software to allow the robot to navigate safely, but also to learn about the objects nearby and navigate to specific items.

That Toy Is Now a Drone

Toys 268

fluxgate (2851685) writes "A notice from the FAA announced earlier this week just turned a bunch of kids' toys into drones. In the past, the FAA had made the distinction between model aircraft (allowed) and drones (prohibited without special permission) according to whether they were used for recreation (okay) or commercial purposes (verboten). Now they have further narrowed the definition of model aircraft: If you fly it through video goggles, it no longer qualifies. This move eliminates First Person View (FPV) radio control flying. I'm an editor at IEEE Spectrum with a special interest and blogged about this disturbing development as soon as I heard the news."

2600 Distributor Withholds Money, Magazine's Future In Limbo

First time accepted submitter themusicgod1 (241799) writes According to 2600, their distributor (Previously known as "Source Interlink", now recently renamed to "TEN: The Enthusiast Network") has decided to consolidate its resources and is keeping the money retailers paid for the last two issues of the quarterly magazine. 2600, in the meanwhile, is still busy trying to organize the upcoming HOPE X conference. However, according to the link: "In the worst case scenario, being ripped off at this level would make it almost impossible for us to continue publishing. We would have to make a lot of painful choices and cut back on things for no reason other than some outside company's mismanagement. Our readers have supported both our print and digital publications and we've been doing quite well overall." Note: As it says at the linked explanation, 2600 is not a charity, and they're not seeking donations -- but they would like you to buy the magazine (in print or Kindle form), and to attend the upcoming HOPE X conference. (I wish I could make this year's HOPE but can't; as conferences go, HOPE is a wildly good bargain.)

Company Uses 3D Printing and Design To Change the Way We Look At Prosthetics

samzenpus posted about a month ago | from the adding-some-flare dept.

Medicine 28

An anonymous reader writes UNYQ (pronounced: unique), a start-up based in San Francisco and Seville, has set out to change the way we look at prosthetics by selling affordable 3D printed prosthetic leg covers, known as "fairings," directly to consumers. The company was co-founded by Eythor Bender, who is best known for developing a prototype bionic exoskeleton that allows paraplegics to walk again. Bender, who has worked with the disabled for over 20 years, was frustrated by the lack of consideration of style in the medical device development process. Despite all the progress made in other areas, the devices still look more or less like a "wooden stick." Bender wants to challenge what we think is possible with prosthetics.
