ENTRIES TAGGED "hardware"
3D Model-to-Printer, GCode Visualizer, AC Power Control, and Public Domain Sadness
- slic3r — converts a digital 3D model into printing instructions for your 3D printer. It cuts the model into horizontal slices (layers), generates toolpaths to fill them and calculates the amount of material to be extruded.
- gCodeViewer — GCode is the “numerical control language” for telling extruders, mills, polishers, etc. where to move to and when. This open source package is a visual GCode visualizer, viewer and analyzer in your own browser! It works on any OS in almost any modern browser (chrome, ff, safari 6, opera, ie10 should work too). All you need to do – is drag your *.gcode file to the designated zone.
- AC Power Control with Arduino — in the video video and the code, we take an in depth look at the hardware for using Arduino interrupts to control AC power through a triac. Using a zero-crossing detector Arduino will detect the pulse then calculate a delay to control the power output to a load.
- What Didn’t Enter the Public Domain Today — a reminder of what the public domain lost because of the Sonny Bono/Disney copyright term extension, timely given there are bad times ahead.
Pattern Recognition, MicroSD Vulnerability, Security Talks, and IoT List
- tooldiag — a collection of methods for statistical pattern recognition. Implemented in C.
- Hacking MicroSD Cards (Bunnie Huang) — In my explorations of the electronics markets in China, I’ve seen shop keepers burning firmware on cards that “expand” the capacity of the card — in other words, they load a firmware that reports the capacity of a card is much larger than the actual available storage. The fact that this is possible at the point of sale means that most likely, the update mechanism is not secured. MicroSD cards come with embedded microcontrollers whose firmware can be exploited.
- 30c3 — recordings from the 30th Chaos Communication Congress.
- IOT Companies, Products, Devices, and Software by Sector (Mike Nicholls) — astonishing amount of work in the space, especially given this list is inevitably incomplete.
Bluetooth LE, Keyboard Design, Dataset API, and State Machines
- iBeacons — Bluetooth LE enabling tighter coupling of physical world with digital. I’m enamoured with the interaction possibilities: The latest Apple TV software brought a fantastically clever workaround. You just tap your iPhone to the Apple TV itself, and it passes your Wi-Fi and iTunes credentials over and sets everything up instantaneously.
- Better and Better Keyboards (Jesse Vincent) — It suffered from the same problem as every other 3D-printed keyboard I’d made to date – When I showed it to someone, they got really excited about the fact that I had a 3D printer. In contrast, whenever I showed someone one of the layered acrylic prototype keyboards I’d built, they got excited about the keyboard.
- Bamboo.io — open source modular web service for dataset storage and retrieval.
Data Tool, Arduino-like Board, Learn to Code via Videogames, and Creative Commons 4.0 Out
- OpenRefine — (edited: 7 Dec 2013)
Google abandoned Google bought Freebase’s GridWorks, turned it into the excellent Refine tool for working with data sets, now picked up and developed by open source community.
- Intel’s Arduino-Compatible Board — launched at MakerFaire Rome. (via Wired UK)
- Game Maven — learn to code by writing casual videogames. (via Greg Linden)
- CC 4.0 Out — The 4.0 licenses are extremely well-suited for use by governments and publishers of public sector information and other data, especially for those in the European Union. This is due to the expansion in license scope, which now covers sui generis database rights that exist there and in a handful of other countries.
Ad Triumphalism, Education Not Transformed, Bookstore Infrastructure, and Tossable Camera
- Why The Banner Ad is Heroic — enough to make Dave Eggers cry. Advertising triumphalism rampant.
- Udacity/Thrun Profile — A student taking college algebra in person was 52% more likely to pass than one taking a Udacity class, making the $150 price tag–roughly one-third the normal in-state tuition–seem like something less than a bargain. In which Udacity pivots to hiring-sponsored workforce training and the new educational revolution looks remarkably like sponsored content.
- Amazon is Building Substations (GigaOm) — the company even has firmware engineers whose job it is to rewrite the archaic code that normally runs on the switchgear designed to control the flow of power to electricity infrastructure. Pretty sure that wasn’t a line item in the pitch deck for “the first Internet bookstore”.
- Panoramic Images — throw the camera in the air, get a 360×360 image from 36 2-megapixel lenses. Not sure that throwing was previously a recognised UI gesture.
Scan Win, Watson Platform, Metal Printer, and Microcontroller Python
- Google Wins Book Scanning Case (Giga Om) — will probably be appealed, though many authors will fear it’s good money after bad tilting at the fair use windmill.
- IBM Watson To Be A Platform (IBM) — press release indicates you’ll soon be able to develop your own apps that use Watson’s machine learning and text processing.
- MiniMetalMaker (IndieGogo) — 3D printer that can print detailed objects from specially blended metal clay and fire.
- MicroPython (KickStarter) — Python for Microcontrollers.
Coding for Unreliability, AirBnB JS Style, Category Theory, and Text Processing
- Quantitative Reliability of Programs That Execute on Unreliable Hardware (MIT) — As MIT’s press release put it: Rely simply steps through the intermediate representation, folding the probability that each instruction will yield the right answer into an estimation of the overall variability of the program’s output. (via Pete Warden)
- Category Theory for Scientists (MIT Courseware) — Scooby snacks for rationalists.
- Textblob — Python open source text processing library with sentiment analysis, PoS tagging, term extraction, and more.
