Portable Squeezebox With Serial

March 2, 2010 by Jakob Griffith 14 Comments

The Squeezbox media streaming systems are compact Linux WiFi enabled radios that let you stream your collection anywhere,so long as you have an AC or USB outlet nearby. But [Achim Sack] wanted to stream his collection from anywhere with no wires attached (translation). Some poking and prodding revealed a connector actually designed for a battery and serial, but no commercially available battery yet.

The system requires a temperature sensor and if you want serial, a USB converter, but overall a simple process that could be done in an afternoon. Giving your box ~10 hour of life and even fits inside of a back compartment.

[Thanks Thomas]

New Pet, Project 413

December 14, 2009 by Jakob Griffith 23 Comments

I wonder if anyone ever mouses over images anymore. Oh silly me, xkcd reference.

[Jacob] sent in his teams final project, Project 413. While sounding like something straight out of an action movie, don’t worry, it’s not the next terminator. Rather a combination of an eBox (in place of an EEE pc), omni wheels, motors, batteries, and the finishing touch – a hamster ferret ball. If this is sounding familiar to a certain web comic, then right you are, as XKCD was their main inspiration. Sadly, the web cam and ‘having a soul’ functions didn’t make it into their version, but being controlled via Wii remote is always a plus. Check out a video after the break.

Hackaday Links: December 7 2009

Ah the beauty of watching molten solder pull SMD components into place. Yeah, we’ve seen it before, but for some reason it never gets old.

The glory days of wardriving are certainly behind us but if you’re still hunting in certain areas for access points you can leave the laptop at home. A homebrew program called Road Dog can turn your PSP into a WiFi search device. You must be able to run custom code to use this app.

Ferrofluid is our friend. But having grown up watching the Terminator and Hellraiser movies we can’t help being a little creeped out by the effects seen in this movie.

Follow along with the NASA astronauts in this 20 minute HD tour of the international space station. It’s a cramped place to live but we can’t help thinking that it looks incredibly clean. After all, where would the dirt come from?

How are your woodworking skills? Can you take a wooden block and turn it on a lathe until you have a lampshade 1/32″ thick? We’d love to see how these are made, but imagine the artist’s reaction when hours of labor are ruined by a minuscule amount of misplaced pressure on a carving tool. Patience, we’ll learn it some day!

This video from the past that is about the future of travel does leave us wondering why our cars don’t have built-in radar for poor visibility? We’ve already realized the rear-view-mirror-tv-picture, but we’re going to need your help before the flying police/fire/ambulance-mobile is a common sight. Oh, the fun of seeing a high-tech push-button selector 3:30 into the video. Perhaps the touch-screen was a bit beyond the vision of the time.

Sometimes you have so many servants you need to find creative things for them to do. Only the most discriminating of the super-rich employ a person whose sole responsibility is to erase and redraw the hands of a clock each minute. This video is obviously a result of the global recession as the live time-keeper has been let go; a looping recording took his job!

Last time we checked in with [Marco Tempest] he was syncing video over multiple iPhones. Now he’s at it again with an augmented reality setup. A camera picks up some IR LEDs in a canvas and translates that into information for a video projector. We’d call this a trick, but it’s certainly not magic.

How To Replace A Netgear Router Antenna

rp-sma-adapter-installed

a.ntivir.us wanted to use a different antenna for their Netgear mbr624gu WiFi router. Unfortunately, this model comes with an antenna that is not removable. As with other antenna retrofits, this involves no soldering. But because there is already a mounting area for an antenna, no case altering is needed either. After opening the router with a Torx driver it was discovered that the non-removable antenna was connected to the board with a mini rf connector (U.FL). The antenna and its mounting bracket were removed and a U.FL to RP-SMA adapter was put in its place using a washer to secure it to the rear plate of the router. Now any external antenna can be used and the router still looks brand new.

WiFi Mapping With A Smartphone

Not so long ago, mapping WiFi required a laptop, GPS, a big antenna and Kismet/NetStumbler. Today’s smartphones have replaced even this task. For those of us running a GPS and WiFi equipped Windows Mobile phone, WiFiFoFum is an excellent and simple solution, as well as a great companion for installing an AP.

Aspire One External Antenna

External antennas on netbooks are notorious, from EEE PCs to the Panasonic CF-R1, but this is the first on an Acer Aspire One we’ve seen. [xRazorwirex] sent in his external antenna hack for the 802.11n capable D150, with the intention of increasing performance, but he says he can’t attest to any change. Unfortunately the lock slot had to be removed, but a small price to pay for a big increase in connectivity. The process seems simple enough, and could probably be done within a half an hour. Now that there is an external link why not build a Cantenna, hop in the car, and HeatMap the neighborhood!

Tunneling IP Traffic Over ICMP

August 21, 2009 by Matt Schulz 21 Comments

icmptx

We all hate it when we find an unencrypted WiFi network at our favorite coffee shop, restaurant, airport, or other venue, only to discover that there are traffic restrictions. Most limited networks allow HTTP and HTTPS traffic only, or so is the common misconception. In the majority of cases, ICMP traffic is also allowed, permitting the users to ping websites and IP addresses. You may be asking, “Ok, so why does that matter?” Well, all of your IP traffic can be piped through an ICMP tunnel, disguising all your surfing as simple ping packets. [Thomer] has a detailed guide on how to create and utilize such a tunnel using ICMPTX. So the next time you are at the local cafe and want to fire up VLC to watch TV shows from your home PC, give this guide a quick read.
