- brick — uncompressed versions of popular web fonts. The difference between compressed and uncompressed is noticeable.
- micio.js — clever hack to communicate between Arduino and mobile phones via the microphone jack.

Remote Working, Google Visualizations, Sensing Gamma Rays, and Cheap GPS For Your Arduino
- Making Remote Work — The reality of a remote workplace is that the connections are largely artificial constructs. People can be very, very isolated. A person’s default behavior when they go into a funk is to avoid seeking out interactions, which is effectively the same as actively withdrawing in a remote work environment. It takes a tremendous effort to get on video chats, use our text based communication tools, or even call someone during a dark time. Very good to see this addressed in a post about remote work.
- Google Big Picture Group — public output from the visualization research group at Google.
- Using CMOS Sensors in a Cellphone for Gamma Detection and Classification (Arxiv) — another sense in your pocket. The CMOS camera found in many cellphones is sensitive to ionized electrons. Gamma rays penetrate into the phone and produce ionized electrons that are then detected by the camera. Thermal noise and other noise needs to be removed on the phone, which requires an algorithm that has relatively low memory and computational requirements. The continuous high-delta algorithm described fits those requirements. (via Medium)
- Affordable Arduino-Compatible Centimeter-Level GPS Accuracy (IndieGogo) — for less than $20. (via DIY Drones)
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.
Arduino Robot, LIDAR for Phones, Climbing Bots, and OS X Emulators
- Arduino Robot — for all your hacking needs.
- LIDAR for Smartphones (DIYdrones) — The device attaches to the back of a smartphone and combines a built-in laser range finder, 3D compass and Bluetooth chip with the phone’s camera and GPS.
- Bridge Inspection Robot Equipping Magnets — 7.8 inches/second, magnets, can scuttle up walls and along ceilings.
- OpenEmu — nice-looking emulator framework for OS X. Make your Christmas present a trip back in time.
Data Tool, Arduino-like Board, Learn to Code via Videogames, and Creative Commons 4.0 Out
- OpenRefine — (edited: 7 Dec 2013)
Google abandonedGoogle 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.
Visual Arduino Coding, Hardware Iteration, Segmenting Images, and Client-Side Adjustable Data View
- Visually Programming Arduino — good for little minds.
- Rapid Hardware Iteration at Scale (Forbes) — It’s part of the unique way that Xiaomi operates, closely analyzing the user feedback it gets on its smartphones and following the suggestions it likes for the next batch of 100,000 phones. It releases them every Tuesday at noon Beijing time.
- Machine Learning of Hierarchical Clustering to Segment 2D and 3D Images (PLoS One) — We propose an active learning approach for performing hierarchical agglomerative segmentation from superpixels. Our method combines multiple features at all scales of the agglomerative process, works for data with an arbitrary number of dimensions, and scales to very large datasets.
- Kratu — an Open Source client-side analysis framework to create simple yet powerful renditions of data. It allows you to dynamically adjust your view of the data to highlight issues, opportunities and correlations in the data.
A strange ad from a defense contractor leads us to talk about technology transfer, and Edward Snowden chooses an unnecessarily inflammatory refuge.
Email Triage, Pulse Detection, Big Building Data, and Raspberryduino Ardpi
- Triage — iPhone app to quickly triage your email in your downtime. See also the backstory. Awesome UI.
- Webcam Pulse Detector — I was wondering how long it would take someone to do the Eulerian video magnification in real code. Now I’m wondering how long it will take the patent-inspired takedown…
- How Microsoft Quietly Built the City of the Future — The team now collects 500 million data transactions every 24 hours, and the smart buildings software presents engineers with prioritized lists of misbehaving equipment. Algorithms can balance out the cost of a fix in terms of money and energy being wasted with other factors such as how much impact fixing it will have on employees who work in that building. Because of that kind of analysis, a lower-cost problem in a research lab with critical operations may rank higher priority-wise than a higher-cost fix that directly affects few. Almost half of the issues the system identifies can be corrected in under a minute, Smith says.
- UDOO (Kickstarter) — mini PC that could run either Android or Linux, with an Arduino-compatible board embedded. Like faster Raspberry Pi but with Arduino Due-compatible I/O.
Underground Economy, Continuous Integration, Chinese Cyber-Espionage, Prosthesis From The Future
- Using Silk Road — exploring the transactions, probability of being busted, and more. Had me at the heading Silk Road as Cyphernomicon’s black markets. Estimates of risk of participating in the underground economy.
- Travis CI — a hosted continuous integration service for the open source community. It is integrated with GitHub.

- $250 Arduino-Powered Hand Made by a Teen — the third version of his robotic hand. The hand is primarily made with 3D printing, with the exception of motors, gears, and other hardware. The control system is activated by flexing a pre-chosen muscle, such as curling your toes, then the movement is chosen and controlled by a series of eyeblinks and an EEG headset to measure brainwaves. The most remarkable part is that the hand costs a mere $250.
