from the tom-swift-and-his-cnc-laser-cutter-would-make-a-great-book-title dept.
Yesterday Glowforge Co-Founder and CEO Dan Shapiro told us that the Glowforge machine is a CNC laser cutter and engraver, not a 3-D Printer -- even though the first words on Glowforge's main page are, "The First 3D Laser Printer," a description Dan says is there for people not familiar with things like laser cutters and 3-D printers, who want to call the Glowforge a 3-D printer even though people who know about this stuff know what it is at first glance. He also talks about his previous startup, Robot Turtles; what it is, how it came to be, and why kids like it so much. This interview is worth watching (or reading) for the Robot Turtles section alone, especially if you have children or are thinking about designing board games for kids.

Glowforge is a CNC Laser Cutter, not a 3D Printer (Video) 44

Co-Founder and CEO Dan Shapiro says, right at the beginning of the interview, that the Glowforge machine is a CNC laser cutter and engraver, not a 3-D Printer. He says they've "simplified the heck" out of the hardware and software, and are making an easy-to-use, non-costly ($2500 has been bandied about as the unit's likely price) device that can fit on a kitchen table -- or, more likely, a workbench at a maker facility. Although Dan did very well on Kickstarter (and afterwards) with his previous venture, Robot Turtles, this time he seems to have raised his first $9 million in the venture capital market, with participation from several MakerBot executives.

Glowforge is not the only CNC laser cutter/etcher device out there (or about to be). In Australia, Darkly Labs appears to have raised $569,397 (AUD) on Kickstarter to bring their LazerBlade to life, and already makes a small laser device called the Emblaser. There are others, too, including Boxzy, which did the Kickstarter thing and will now sell you a device that "rapidly transforms into 3 kinds of machines: CNC Mill, 3D Printer & Laser Engraver while enhancing precision & power with ballscrews." All this, and their top-of-the-line "does everything" machine sells for a mere $3500. Obviously, devices to give makers and prototypers the ability to make ever more complex and accurate shapes are coming to market like crazy. We'll continue to keep an eye on all this activity, including a second video interview with Glowforge's Dan Shapiro tomorrow.

An anonymous reader writes: Those of us who fiddle with electronics are probably familiar with this scenario: you've just finished assembling a project using your Arduino/Raspberry Pi/whatever, and it works! You'd like to set it up for long-term use, but... it's just a mass of wires and LEDs and switches. Alexis Matelin has written up a brief but handy guide for turning that mess into a self-contained prototype. He goes from planning out your circuit to designing your schematic to making your board, then working on an enclosure and a battery holder. Matelin also links to a variety of resources for the individual steps involved. It's a straightforward guide written for amateurs. Those of you who have experience with building permanent micro-controller projects: what would you add?

Apple Watch's Hidden Diagnostic Port To Allow Battery Straps, Innovative Add-Ons 113

Posted by samzenpus
from the corkscrew-now-included dept.
MojoKid writes: Apple's Watch launched two weeks ago to some unbelievable hype and coverage in the press. However, it appears one feature flew under the radar and Apple actually had just one more trick up its sleeve. You see, on one side of the watch face is a hidden door that exposes a 6-pin port. It's assumed that this could be used for diagnostic purposes, but with an Apple Watch in hand, a company by the name of Reserve Strap was able to verify that it could also be used for charging. This seems pretty huge and strange at the same time: why would Apple keep such a thing quiet, when the Apple Watch's battery-life isn't what most people would consider impressive? Even more interesting is the fact that Apple didn't make use of this port to release its own charging straps — watch straps that carry a charge themselves. Apple's lack of transparency here doesn't much matter, though, as the aforementioned Reserve Strap is planning to get such a product to market as soon as possible. The company says about its first offering: "The Reserve Strap will come in White, Gray and Black and will fit both the 38mm and 42mm case sizes. The first batch of straps will be shipped in the Fall.

from the build-it-one-piece-at-a-time dept.
According to Wikipedia, 'Project Ara is the codename for an initiative that aims to develop an open hardware platform for creating highly modular smartphones.' Google is the sponsor, and the project seems to be moving faster than some people expect it to. There's a Project Ara website, of course, a GitHub repository, a Facebook page, even an Ara subreddit. During his conversation with Timothy Lord, Ara firmware project lead (and spokesman) Marti Bolivar said it won't be long before prototype Ara modular phones start user testing. Meanwhile, if you want to see what Marti and his coworkers have been up to lately, besides this interview, you can read a transcription of his talk (including slides) from the January Project Ara Developers Conference in Singapore.

Another 'Draw Your Own Circuits' System at SXSW (Video) 27

from the is-this-an-easy-way-to-connect-the-'rear'-speakers-in-your-home-theater-system? dept.
While Timothy Lord was at SXSW, he chatted with Yuki Nishida of AgIC and learned about the company's conductive ink products. But AgIC wasn't the only company at SXSW showing off conductive ink. You could also meet the Electroninks people and see their Circuit Scribe product, which had a Kickstarter campaign a while back that raised $574,425.

This kind of product seems to be attractive to the kind of people who fund Kickstarter projects, and this bunch seems to have good resumes and some interesting, well thought-out products. There is apparently room in the 'draw circuits and learn electrical basics' market for both AgIC and Electroninks -- and probably for another dozen competitors, too.

eBay Sales Patterns Show That the Maker Movement is Still Growing (Video) 24

Posted by Roblimo
from the homemade-always-tastes-better dept.
Meet Aron Hsiao. He works for Terapeak, a company that tracks sales through online venues such as eBay and Amazon in order to help merchants decide what to sell -- and how. The five 'maker' categories Terapeak tracks (drones, robotics, Arduino, Raspberry Pi and 3D printing) outsold Star Trek-related merchandise by a huge amount, namely $33 million to $4.3 million, during a recent 90 day study period. Star Wars merchandise did better at $29.4 million, but still... And as another comparison, Aron says that all Apple laptops combined, new and used, sold $48.4 million, so the DIY hobbyist movement still has a ways to go before it catches up with Apple laptops -- but seems to be heading steadily in that direction.

Drones are the hottest hobbyist thing going right now, Aron says, but all five of the hobbyist/tinkerer' categories Terapeak tracks are growing steadily at a rate of up to 70% year over year, with drones leading the way and robotics trailing (but still growing). It's good to see people taking an interest in making things for themselves. If you remember (or have heard of) the Homebrew Computer Club, you have an idea of what tinkerers and hobbyists can produce if given even a tiny bit of encouragement. And it's good to see that the DIY mindset is not only still alive, but growing -- even if it seems to be moving away from traditional hobby tinkering (cars; radios) toward concepts (drones; robotics) that weren't considered mass market 'homebrew' possibilities even a few years ago.

Armstrap Claims to Make ARM Prototyping Easier (Video) 41

Posted by Roblimo
from the not-just-easy-but-fun-too dept.
It almost seems too perfect that the originator of the Armstrap 'community of engineers and makers' is named Charles Armstrap. He just introduces himself as 'Charles' on the Armstrap.org website. Names aside, Armstrap.org is 100% open source, including circuit board designs. This is not a 'draw your own circuit boards' bunch, although you certainly could if you wanted to badly enough since they provide schematics and even full CAD drawings of what they make. The reason they do this is laid out on their Core Values page. The boards Armstrap sells are not expensive, but if you are going to be truly open source, you need to supply the means to duplicate and modify or extend your work, as is totally permitted under the MIT License they use.

Turning the Arduino Uno Into an Apple ][ 113

Posted by Soulskill
from the what's-new-is-old dept.
An anonymous reader writes: To demonstrate how powerful modern computers are compared to their forebears, engineer Damian Peckett decided to approximate an Apple ][ with an Arduino Uno. In this post, he explains how he did it, from emulating the 6502 processor to reinventing how characters were displayed on the screen. "The Apple II used a novel approach for video generation, at the time most microcomputers used an interlaced frame buffer where adjacent rows were not stored sequentially in memory. This made it easier to generate interlaced video. The Apple II took this approach one step further, using an 8:1 interlacing scheme. This had the first line followed by the ninth line. This approach allowed Steve Wozniak to avoid read/write collisions with the video memory without additional circuitry. A very smart hack!" Peckett includes code implementations and circuit diagrams.

Building an NES Emulator 140

from the thank-you-mario,-but-that-register-is-in-another-castle dept.
An anonymous reader writes: Programmer Michael Fogleman recently built his own emulator for the original Nintendo Entertainment System. He's now put up a post sharing many technical insights he learned along the way. For example: "The NES used the MOS 6502 (at 1.79 MHz) as its CPU. The 6502 is an 8-bit microprocessor that was designed in 1975. ... The 6502 had no multiply or divide instructions. And, of course, no floating point. There was a BCD (Binary Coded Decimal) mode but this was disabled in the NES version of the chip—possibly due to patent concerns. The 6502 had a 256-byte stack with no overflow detection. The 6502 had 151 opcodes (of a possible 256). The remaining 105 values are illegal / undocumented opcodes. Many of them crash the processor. But some of them perform possibly useful results by coincidence. As such, many of these have been given names based on what they do." It's an interesting look at how software and hardware interacted back then, and what it takes to emulate that in modern times. Fogleman released the source code on GitHub.

Hand-Drawn and Inkjet Printed Circuits for the Masses (Video) 33

Posted by Roblimo
from the give-your-kids-paper-plates-with-lights-that-tell-them-to-eat-their-veggies dept.
We started looking at ways to make instant hand-drawn or inkjet-printed circuit boards because Timothy met an engaging young man named Yuki Nishida at SXSW. Yuki is a co-founder of AgIC, a company that makes conductive ink pens and supplies special paper you can use to write or draw circuits or, if you have the right model of Brother printer, to print them with special inkjet inks. The AgIC people are aggressively putting the 'A' in STEAM by marketing their products to artists and craftspeople. Indeed the second line on their website's home page says, 'AgIC offers handy tools to light up your own art works.' This is an excellent niche, and now that AgIC has developed a circuit eraser (due to ship this April), it may lead to all kinds of creative designs. And as is typical with this kind of company these days, AgIC has been (at least partly) crowdfunded.

A little cursory Google searching will soon lead you to other companies selling into the home/prototype circuit board market, including Cartesian Co and their Argentum 3-D printer that does prototype and short-run PCBs and only costs $899 (on special at the time this was written) and Electroninks, which markets the Circuit Scribe pen and associated materials with an emphasis on education. There are others in this growing field, and a year from now there will probably be more of them, all working to replace the venerable breadboard the same way electronic calculators replaced slide rules.

An anonymous reader writes Ben-Gurion University of the Negev (BGU) researchers have discovered a new method to breach air-gapped computer systems called "BitWhisper," which enables two-way communications between adjacent, unconnected PC computers using heat. BitWhisper bridges the air-gap between the two computers, approximately 15 inches apart that are infected with malware by using their heat emissions and built-in thermal sensors to communicate. It establishes a covert, bi-directional channel by emitting heat from one PC to the other in a controlled manner. Also at Wired.

You Can Now Clone Samsung's Gear VR and Test Your Virtual Reality Apps 32

from the more-real-than-real dept.
An anonymous reader writes While Samsung's Gear VR headset launched in early December in the U.S., folks abroad didn't have any official means of buying the headset to test their in-development applications. Only recently has Gear VR begun making its way to countries around the world, and it's doing so slowly. For developers who don't want to wait (or DIYers who don't want to buy), some smart folks have figured out how to emulate the headset using a development board with an IMU that's been flashed with the same firmware found on the Oculus Rift DK1 headset. Plugging the board into the Note 4 (the smartphone that powers Gear VR), results in the phone recognizing the IMU as the Gear VR headset, allowing developers to test their applications and even launch the "Oculus Home" environment, allowing access to official applications and content.

Researchers Moot "Teleportation" Via Destructive 3D Printing 163

Posted by timothy
from the don't-tell-the-mpaa dept.
ErnieKey writes Researchers from German-based Hasso Plattner Institute have come up with a process that may make teleportation a reality — at least in some respects. Their 'Scotty' device utilizes destructive scanning, encryption, and 3D printing to destroy the original object so that only the received, new object exists in that form, pretty much 'teleporting' the object from point A to point B. Scotty is based on an off-the-shelf 3D printer modified with a 3-axis milling machine, camera, and microcontroller for encryption, using Raspberry Pi and Arduino technologies." This sounds like an interesting idea, but mostly as an art project illustrating the dangers of DRM. Can you think of an instance where you would actually want the capabilities this machine claims to offer?
