RetroShare. Since 2013, the web site PRISM Break recommends RetroShare for anonymous file sharing.[5] The number of simultaneous users is, in January 2014, more than 5800.[6] Authentication and connectivity[edit] After installation, the user either generates a pair of (GPG) cryptographic keys with RetroShare, or selects an existing keypair to use. After authentication and exchanging an asymmetric key, SSH is used to establish a connection. End to end encryption is accomplished by using OpenSSL. File sharing[edit] Files are represented by their SHA-1 hash value, and HTTP-compliant file and links may be exported, copied, and pasted into/out of RetroShare to publish their virtual location into the RetroShare network.
Communication[edit] RetroShare offers several services to allow friends to communicate : User interface[edit] The core of the RetroShare software is based on an offline library, to which two executables are plugged : Anonymity[edit] Features[edit] Reception[edit] Future developments[edit] Ultimate Boot CD - Overview. M-TAGS component (foo_tags) M-TAGS (foo_tags) I created this for my own use. I am sharing it because if I have a need for it, maybe someone else does too.... The m-TAGS format offers a simple yet powerful solution to the media-metadata separation problem, which impacts the efficience of digital music collections and media distribution services alike. An m-TAGS file is media-independent. It just contains metadata (tags) describing a certain media source and a locator which identifies the source to which the metadata applies.
The format of an m-TAGS file is very simple. Download the component here: For additional information and technical details please visit Usage For a first "taste" of how the m-TAGS mechanism works, select File / m-TAGS / Create m-TAGS (in same folder) from the main menu. A new file will be created in your folder, named !. Your audio files will play normally, but any changes to the metadata will be reflected in the !.

Optical Tremolo Box. MAKE contributing editor Charles Platt proposed a “Hypothetical Tremolo Wheel” in his article about online DIY guitar stomp-box communities (MAKE Volume 15, page 82, “Stomp Box Basics: Tremolo and Fuzz”). Well, it’s hypothetical no more. I took Charles’ cue and built this Optical Tremolo Box, which reads a patterned disk with a light sensor to create a warbling volume effect (tremolo) that you can custom-program with any pattern you like. How does tremolo work? So there’s your electric guitar, and there’s the amplifier it’s plugged into, and there’s the cable that runs between them.
Open up that cable and you’ll find 2 wires — one “ground” and one held at a positive voltage relative to “ground.” The changing electrical potential between these 2 wires, over time, is what carries the sound signal. What happens if you short-circuit those wires, bridging them with a third wire? What if you bridge the 2 wires with a resistor instead? Intrigued? Buy now!

PirateBox DIY - David Darts Wiki. Turn Your $60 Router into a User-Friendly Super-Router with Tomato. DD-WRT Tutorial 3: Building a Wireless Bridge. You can connect a wired device to a wireless network by turning an old Linux router into an Ethernet-to-wireless adapter. Not too long ago, we were promised a world in which virtually every electronic gadget could connect to a network, talking to one another, exchanging data, joking and laughing and basically enjoying the fruits of an electronic utopia. We were also promised flying cars. Where is my flying car!? We’re inching our way there. Networking abilities are appearing in more non-traditional electronic devices, including some digital audio players, some digital cameras, printers, and specialized devices like the Xbox gaming consoles. But even as networking expands its reach, wireless networking in non-PC electronics is further behind still.
But wait! Bridge For Sale Some products, like the Xbox, support specialized wireless bridges specifically made for this purpose. In either mode, you have a primary router and a secondary router.

Wireless LCD in 5 minutes! Today, I was thinking how dirty and full of stuff my desk was. So I decided to relocate my graphic LCD to another person's desk but still have control over it. To do this, I figured I could simply use the ACODE-300 wireless bluetooth modules. [Larger Image Download] You can connect your devices as shown in the above schematic. (Make sure to use sockets for the ACODE-300 modules, so you can plug and un-plug the modules for setup) When you are done making the above, you will ultimately end up with the below: (Study Board & ACODE300) (ACODE-300 Proto board for Study Board Close-up) (front of GHLCD) (back of GHLCD w/ my ACODE-300 Proto board installed) (My ACODE-300 Proto board for graphic LCD Close-up) (Connections to TTL Outputs of GHLCD & Baud rate set to 115200) The ACODE-300 Bluetooth modules are very easy to use and can be applied to any serial RS232 interface. When you are done making your proto-boards and connections,you are ready for testing.
(LEDs continuously ON) Digital Signal Processing. RTL-SDR community on Reddit. AI-Class: "Introduction to Artificial Intelligence" /r/netsec - Information Security News & Discussion. Electronic systems, circuits, signal processing... Dub Cadet: Holographic MIDI & LED Controller for Arduino - Part 1. I believe holographic musical instruments will be commonplace in the future, showing up everywhere from schools (for education), to homes (for fun), to media offices (for creativity), and in music studios (for production).
The reason is simple: The holographic musical instrument takes a complex process and radically simplifies it: see another demo video here. I'm using the term 'holographic music' to mean multidimensional musical structures mapped to 3d surfaces to be decoded through rotational motion. Just as optical holograms modulate light based on the 3D viewing angle, we can modulate sounds based on the relative 3D orientation of an object. This is Part 1 of a 3-part series on a technology that I am calling the Dub Cadet: a holographic musical instrument. Part 1 will discuss theory and technical strategy, Part 2 will provide an arduino-based hardware solution, and Part 3 will explain the programming code that makes it work.
Funtendo - A multistick retro controller for your PC. Audio Delay Module. This project shows you how to make a unit which can produce a delay of up to 8 seconds on an input audio signal. The circuit outputs a delayed version of an input audio signal. Depending on the amount of memory implemented and the sampling rate selected, it can store from 3 seconds to 8 seconds of audio. The audio input will be delayed by an amount selectable by the user. This device can be used to produce a delay for many purposes. Sound effects , such as echo, can be produced by adding a delay to an input signal. At any rate, the device described here can be a lot of fun to play and experiment with. Audio Cassette Loop. How to Listen to RADAR Signals From Space. This instructable can be accessed at the author's website - If you link to this instructable from another website, please include a link to the Neat Information website. This article is copyrighted and may not be reproduced without permission.
Okay, the title of this instructable is a little bit misleading. We’re not going to listen to RADAR signals from space (which would require a giant transmitter in outer space), but RADAR signals transmitted from Earth which have bounced off of something in space. That something could be a satellite (the International Space Station, Hubble Space Telescope, etc.), a piece of space junk, a meteor as it enters the Earth’s atmosphere, an asteroid passing too close to the Earth for comfort (but at least passing safely instead of hitting the Earth), or even the moon.
The Air Force Space Surveillance System consists of three extremely high power RADAR transmitters in a East-West line across the southern United States. Listening to Satellites on a Handheld Scanner. Check out the author’s website, for lots of interesting articles. If you link to this instructable from another website, please include a link to the Neat Information website. This tutorial is more of an introduction about what’s possible rather than specific procedures. If you find it interesting then use your favorite search engine to look for additional information. Handheld scanners are typically sold in electronics shops. They’re usually advertised as police-fire band or NASCAR. But they’re useful for far more than that, covering a wide variety of frequencies and can even be used to listen to signals from satellites.
A relatively simple new scanner will cost around $100. Anybody (at least in the United States) is permitted to monitor non-cellular radio frequencies. The trick is line-of-sight. So what’s higher than outer space? Bluetooth SNES Controller for Android. So this is my first instructable... A little over a year ago I was working on my ECE senior design project, which was a bluetooth SNES controller for Android.
Shortly after completing the project, I posted a working video on Youtube. Since then I have received quite a few requests for more info or even a tutorial on how to make one. I figured I had put it off long enough, and now I finally got a video together. I apologize in advance for the sub-par production value (I'm no Ben Heck), it was literally my first exposure to iMovie, and I'm sure it shows. Here is the source code for the Arduino, along with my Easymote app from the tutorial (you won't find it on the market) Arduino source: Easymote apk: Here is a video showing my battery operated controller along with playing some Donkey Kong and Zelda on my Touchpad, unfortunately my rechargeable controller was built for a contract and I no longer have it:
Controlling an Arduino Board Using an Infrared Remote Control. Home automation server with router. Install the Linux based OpenWRT firmware on the router. The TL-WR741ND instructions can be found here: If you are stuck, start here: After you have a working SSH connection you can proceed. Because of the router (by default) runs the web admin page on the port 80, we need to add a secondary port to serve our custom web site. For that, we need to configure the uhttpd (web server application) configuration file. Download WinSCP, to simply do this through SSH.
Set up a new connection: Host name: normally 192.168.1.1 (by default) Port: 22 User name: root Password: what you gave after installation File protocol: SCP Find this file: /etc/config/uhttpd Copy the following into it: config 'uhttpd' 'secondary' option 'listen_http' '81' option 'home' '/HomeAutomation/www' option 'cgi_prefix' '/cgi-bin' option 'script_timeout' '60' option 'network_timeout' '30' And save it.
Set Up a Fully Automated, Torrent-Seeding Media Center. SExpand @macrumpton: Click the image for the full size to see what I'm talking about. Here's a side-by-side shot of Miro and MPC, both playing the same frame of "Pioneer One" S01E01 720p (h264) mkv file. Notice the difference in quality. XBMC and Boxee are comparable to MPC, I just used that for a quick screen shot (not full screen by default). Even if you don't want to go the media center route, and are content with Miro for downloading, I highly suggest you get a good graphics card (if you need one) and a separate program to decode and play back the files.
Miro is not comparable to a true Media Center by any stretch of the imagination. Things Miro is lacking: • Good support for remotes and internet/eventserver based control for phones. • Proper databasing (sort by name, aired date, release date, actor, genre, MPAA/TV rating, duration...) • Auto-discovery of missing supplemental media (Fanart, screen caps, cover art, subtitles and lyrics etc.) • Boot as an OS for HTPCs • Media flagging.
