Two men and their journey to find a solution – from 10,000 miles apart. RaspberryPi Fondles Wii-Nunchuck, Controls LED-Stripe Panel, Plays Snake » shackspace = der hackerspace in stuttgart. Allgemein Januar 22nd, 2013 shackspace hacker @4RM4 was looking for something to hack when he visited 29c3.
He found someone who was selling RGB-LED stripes with individually addressable LEDs which was (understandably) irresistible and he already had a RaspberryPi to control it with. Controlling the stripe is done via one of the Pi’s SPI ports. However there was nothing to mount the stripe to… except for a trash bin. Getting Started with D3. D3 Presentation. Thinking with Joins. Say you’re making a basic scatterplot using D3, and you need to create some SVG circle elements to visualize your data.
You may be surprised to discover that D3 has no primitive for creating multiple DOM elements. Wait, WAT? Sure, there’s the append method, which you can use to create a single element. svg.append("circle") .attr("cx", d.x) .attr("cy", d.y) .attr("r", 2.5); Server Download - Repetier Software. Repetier-Server is a multi-printer multi-connection printer server to handle the communication with 3d printer.
Design targets were: Small memory usage. Should run on a Raspberry PI with 256MB RAM. Handles one printer with 5MB of memory regardless of the print size.Cache print files on disk to allow any size of print. Introduction. This essay is an attempt to put down my thoughts on how to design a real-world yet beautiful RESTful API.
It draws from the experience I have gained being involved in the design of the RESTful API for Red Hat’s Enterprise Virtualization product, twice. During the design phase of the API we had to solve many of the real-world problems described above, but we weren’t willing to add non-RESTful or “RPC-like” interfaces to our API too easily.

Wardrive, Raspberry Pi Style! I purchased a Raspberry Pi a few weeks back.
I found that I could power it, a WiFi card and a GPS from my 12000mah Li-Ion battery pack for about 12 hours. What a great way to explore with out having to have a huge laptop or giant battery in my bag. From that I did a little bit of driving and biking with this tool kit, passively looking for and logging networks. I could have easily used my NinjaTel phone (and will attempt this in the future), but I wanted something that I didn't have to mess with to much and would have a long batter life to "power all the things". From this I found that out of 6,164 APs identified, that only %5 had WEP configured (which is flawed). Hardware Used Hardware Notes The Raspberry Pi model B uses 700mah of power alone. Install the OS First thing to do is get the Pi OS setup. Install Dependencies Once our OS is installed, we will then need to add the necessary packages to support kismet. OPENROV. Goes to Antarctica - OPENROV.
The Kickstarter backers weren't the only ones waiting for a delivery before the holidays.
On the icy tundra of Antarctica, Eric was eagerly anticipating the arrival of a few key parts so he could test the OpenROV under the ice. Well, he got the package in time. Even though he got the parts, I still wasn't sure if he would find the time to run the tests. The last I had heard from him, he was busy piloting larger ROVs or tagging orca whales with homing devices. Taking advantage of every second of safe conditions on the edge of the ice shelf. (1) 3D Printing Adventure - Rome, Italy - Slic3r. SciEngSoc - future programme. Buda-style Reprap Hotend/Hot End for 3mm filament 3D Printer. LEAD TIME: 7 days It is based on the Budaschnozzle 1.1 design by Lulzbot.
This hotend is becoming standard on all incoming Airwolf 3D printers. Starting with the Buda design, we enhanced and simplified the hot end by eliminating the threaded collars that held the hot end together. Over time, we found the bolts tended to work themselves loose. Automating the Blade MCX. The Blade MCX is a favorite of indoor micro UAV autopilot designers, even in the age of micro quad copters.
The time had come to automate one. A test of a Ladybird showed the Blade MCX was much more stable. It automatically damps its horizontal motion to a freakish level.

We are also able to debug programs using gdb + openocd. But command line building and debugging projects isn't fun, is it? No problem.

All in Assembly, but the commenting is extensive. Only thing is that the majority of the comments are in (taking a logical guess) German. Picopter’s maiden flight! « Botched. Over the past few weeks I've been working on a raspberry pi powered quadrocopter, finally cumulating in todays first test flight! This flight went infinitely better than I expected, as it seems I have guessed nearly perfect PID gains. The Picopter is currently based on the same filtering and control algorithms as my previous platform, however now all of the processing is handled by the on-board Raspberry Pi. This initially seems rather counter intuitive, as time sliced operating systems like Linux are not as predictable in their execution time as a simple real-time microcontroller program, but I've found in practice preemption allows the main control loop to run at a very reliable frequency.
Creating Custom Xcode 4 Project Templates. December 5th, 2011 Filed under: Xcode This post contains the material on custom project templates I had prepared for the book. The material was not strong enough to put in the book, mainly because creating custom project templates manually in Xcode 4 is difficult (much more difficult than in previous versions of Xcode) and not documented by Apple. I had a difficult time getting a simple project template to work. A minimal project template for Xcode 4. MariaMole. Welcome to phatIO. G-Code Tutorial: Basic Concepts for Beginners. Steup/AVR-HaLib.
