Slic3r - G-code generator for 3D printers Designing a Vector Terrain Map for Outdoor Apps We are starting a major update to MapBox Terrain. We are designing this specifically for outdoor apps, making it easy to find running trails, check out ski slopes, or visualize your bike rides. There are two main aspects to the work in progress. First, we want to integrate hillshade and landcover data into the vector tiles workflow. This allows for a very high degree of design control and labeled contour lines down to zoom level 19 (currently at 15). Here’s an interactive demo of the San Francisco Bay area. Outdoor details Adding more details from OpenStreetMap is relatively straightforward in a technical sense. One of the features we’re focusing on is cycling. Relief and elevation Our terrain layer includes both shaded relief (hillshades) and elevation contour lines. Compared to our current terrain layer, the hillshades in our experimental layer are quite different. The power of vector tiles Working with vectorized hillshades as opposed to raster hillshades brings a lot of flexibility.
carlosgs/Cyclone-PCB-Factory enf : Happy to announce the new GPS... Cyclone PCB Factory Cyclone PCB Factory Documentation Cyclone PCB Factory v2.1 Release status: working Introduction The Cyclone PCB Factory is a 3D-printable CNC Mill released in May 2013. A summary on the Cyclone development can be found in this article. The new Cyclone v2.0 has been released! Video summary of Cyclone, as of Summer 2013: Pictures Milling plexiglass by Martin Zabojnik (video) Dimensions The external dimensions of the Cyclone PCB Factory are approximately 25x30x40 cm (intended footprint was a DIN A4 paper sheet). The machine is optimized to work with 100x160 PCB boards and has ~3cm of usable Z range. Main improvements The following is a list of the main improvements that this project is developing: Rep-Rap alike, anyone can print the parts and build it Simple implementation of Z height probing to allow high precision milling (see the Software credits for details) Development The development of the Cyclone PCB Factory is hosted on github: Mail list / Forum
ian_villeda : .@gergmuure check out... RAMPS 1.4 Release status: Working In RAMPS 1.4, the resistors and capacitors are now surface mount to fit more passive components. This does add another set of steps to assembly, but we stuck with larger sizes to make it fairly painless. Reference board orientation is component side up, power inputs to the left. Once you start putting electricity into your RepRap - even at just 12 volts - you have to take basic, common sense precautions to avoid fires. A "thermals" design flaw has been noted in the RAMPS 1.4 Eagle CAD files. This image is also in error (it isn't: it's a photograph of an existing production RAMPS 1.4 board), the left two unpopulated pins on the image are for the always on fan and use very little current. The problem may be fixed in the Eagle CAD files - for a future version of RAMPS only - by disabling "thermals" on the GND, +12V and the +12V2 Copper pour. Other production boards found in the wild Another production 1.4 board, also sourced from China. Component Soldering Required Tools
MapBox : Monitoring DC gunfire with... YouTube Heated "One on One" debate between Cenk Uygur (The Young Turks) and Ann Coulter at the 2015 Politicon Conference in Los Angeles. Friday October 9th Hour 1: Power panel live at Politicon, Cenk, Ben, Iadarola, and Jimmy in front of a live audience. Talk about another shooting at another college campus this morning. One person is dead at Northern Arizona University. Ben Carson told CNN’s Wolf Blitzer that Hitler might not have gained so much power if the people only were allowed to have guns to the extend America has. A poll showed that 80% of the public is in favor of getting rid of Citizens United. Hour 2: Ana replaces Iadarola on the panel. Justin Bieber was photographed by paparazzi without his pants on.
An Intriguingly Detailed Animation of How People Move Around a City - Emily Badger Much of what we know about how people move around a metro area – whether they drive to work, where they're going, how many stops they make along the way – comes from travel diaries that sample households periodically fill out. Increasingly, we can supplement this information with meta-data from new sources like social media, cell phones, or electronic transit fare cards. But the old-fashioned household travel survey still does the best job of nailing down the details: whether that traveling dot seen from a Foursquare visualization is on a bus or in a car, if she has a job, how much money her household makes. To give a sense of what that data looks like – and what kind of patterns emerge from it – UC Berkeley planning Ph.D. student Fletcher Foti animated some of the results of the most recent surveys from the San Francisco Bay Area, Los Angeles, and New York. His animation (which pauses briefly at each hour) is also sortable by income: And here are those making more than $200,000:
