german Citizens’ band radio over the internet…Freies Funknetz!

The internet makes things possible some people dreamt of for years. One of these things is the possibility to stream live-voice-chat over the internet. Many people used the citizens’ band radio – CB radio – for the last decades:

Citizens’ Band radio (CB) is, in many countries, a system of short-distance, simplex[1] radio communications between individuals on a selection of 40 channels within the 27 MHz (11 meter) band. The CB radio service should not be confused with FRS, GMRS, MURS, or amateur (“ham”) radio. Similar personal radio services exist in other countries, with varying requirements for licensing and differing technical standards. In many countries, CB does not require a license and, unlike amateur radio, it may be used for business as well as personal communications.”

For several years now there is a group of people from virtually everywhere in germany who connect their CB radios to the internet – they link their “gateways” together using a software normally used by online gamers called “TeamSpeak”. All you have to do to take a look is to read this short how-to and follow the steps.

Here’s a sneak-peak at the current status of the server:

There’s even a livestream available (but sometimes not working):

CHDK – the alternative firmware for many Canon Digital Cameras

“CHDK is a firmware enhancement that operates on a number of Canon Cameras. CHDK gets loaded into your camera’s memory upon bootup (either manually or automatically). It provides additional functionality beyond that currently provided by the native camera firmware.

CHDK is not a permanent firmware upgrade: you decide how it is loaded (manually or automatically) and you can always easily remove it.”

chdk

Main features:

  • Save images in RAW format
  • Ability to run “Scripts” to automate the camera

  • Zebra mode (blinking highlights and shadows to show over/under exposed areas)
  • An “always on” full range Battery indicator
  • Ability to turn off automatic dark-frame subtraction
  • a higher compression movie mode, and double the maximum video file size
  • exposure times as long as 65 seconds
  • exposure times as little as 1/10,000 of a second

this is what Flip3d should have been…

Switcher is the name of the tool that is available since some months and if you ever used Flip3d in Windows Vista you maybe know what it means when I say: Switcher is the Flip3d that should have shipped with Vista.

There are several usability issues with Vistas built-in Flip3d, take a look:

First of all you just don’t see the content of the windows… then you don’t see their name… then… who came up with that layout?

Compare that to the UI of Switcher:

Neat, isn’t it? Try it, love it.

the solution for the Windows Vista Event ID 4226 problem (TCP/IP security limit)

“Apparently in Windows Vista, Microsoft still enforce and hard-limit (hard coded in tcpip.sys) the maximum simultaneous half-open (incomplete) outbound TCP connection attempts per second that the system can make, as in Windows XP SP2, in order to protect the system from being used by malicious programs, such as viruses and worms, to spread to uninfected computers, or to launch distributed denial of service attack (DDoS). When the limit is hit, in Event Viewer, there will be such an entry:”

How to fix that and the needed tools can be read and downloaded here.

Disco Dance Floor

“Our flagship product, the Disco Dance Floor Controller Board is capable of controlling up to 192 LEDs (with 4-bit intensity control) and 64 binary switches via a USB interface. Using the included source code, a refresh rate of 17 frames per second is easily achieved. With some environment specific modifications to the software, rates in excess of 30 frames per second may be achieved. Multiple boards may be connected together using USB hubs to control additional LEDs and switches.”

switching to dvorak keyboard layout

While cleaning my keyboards the idea came up to actually use dvorak keyboard layout I wrote about more than a year ago.

After creating the “dovrak german type 2” keyboard layout file with Ukelele I am now slowly learning the new layout… quite hard after more than 16 years on QWERTZ/QWERTY…

Well… both Apple Keyboards are now dvorak-layouted… looks a bit strange when you’re only known to QWERTZ/QWERTY

If you like you can download the OS X keyboard layout here.

802.1x with certificate based authentification in Windows Vista RC1

I had this very very annoying problem that Windows Vista since the July CTP refresh wasn’t able to connect to my home 802.1x certificate based wireless network. It just did not work as supposed…

But with the help of the RC1 Wi-Fi support specialists I got it working. If you run into the same problem, just do the following to solve it:

  • delete all manual set-up profiles for your 802.1x wireless network (if there are any)
  • download the Wireless Network Connection-evilgate.zip (,63 KB) and edit the included .xml file. You have to edit the SSIDs,…
  • open a command prompt and run:

netsh wlan add profile “profile.xml” “Wireless Network Connection” all

  • you have to change “profile.xml” to the filename of your .xml file and “Wireless Network Connection” to the name of your connection

Et voilá! A message should show up asking you for the certificate…

UPDATE: well you could also create a manual profile for your wireless network and export it to an xml file:

netsh wlan export profile “SSID”

YAPS TV-Browser Plugin

After using the “Web-Search”-Plugin of TV-Browser to program new recordings into YAPS, ello came across with the idea to use the “Capture”-Plugin instead.

And after doing so: It’s incredible what that Capture Plugin can do!


in the context menu: the “Record”-Button


specify the title..and you’re done…

The Capture Plugin does several things:

  • making the programming of new recordings as easy as possible
  • showing visually that this particular episode will be recorded
  • allowing you to remove the recording from the schedule

And all you have to do to add this functionality to your TV-Browser is:

  1. download: YAPS TV-Browser Plugin
  2. import the YAPS.tcf file into the Capture-Plugins Device Listing (Import Button)
  3. configure the server name and the channel-name mappings

When you’re done with that everything should work. Oh… I have to admit: The record delete functionality is not quite working as it should…but it will in some of the next builds…

Thanks to the TV-Browser team for creating such a great application!!! Keep on the good work!

Do (almost everything) by yourself website…this time: building a Segway

I am running into several Do-it-yourself websites these days; and one of them is zedomax.com. This website tells you very interesting electronic tales, like this one:

Once upon a time, I wanted to get me a segway. But since I didn’t want to bite the bullet I just made one myself…

“The author says, “The current software, now in C running in an onboard 8-bit microcontroller, is only 500 lines of code.””

How to build a panoramic tripod for less than 10 EURO

Stitching software and digital cameras make panoramic photos far easier than ever before. However, to get the best results, you need a special tripod head. These can cost hundreds of dollars, but making your own isn’t that hard. Even better, it’s dirt cheap.

future case modding trend?

Wait until the case modding scene finds out about that… color changing heatsinks…omg!

Persistence of Vision is not only a raytracer…

Yesterday I wrote about the bike mounted POV display. And today? Well. It’s a real huge display:

“Spin uses Persistence of Vision to create the illusion of a cylindrical
digital display (computer screen), 12 feet tall and 12 feet in diameter. Vertical
columns of multi-color LED (light emitting diode) clusters spin around a vertical
axis at 90 revolutions per minute. At a radius of 6 feet, they move at 41 miles
per hour. 2880 LEDs are turned on and off by a computer in precise synchronization
with the rotation of the columns, creating the illusion of a cylindrical digital
display. Spin has a vertical resolution of 16 pixels (picture elements), each
of which can display one of 8 colors. As horizontal position is determined by
time in Spin, the horizontal resolution is theoretically infinite, but for the
sake of data manipulation efficiency it is be limited to 360 pixels all the
way around the cylinder.”

Mario Kart Source…

No no no! I am not writing about the sourcecode of Mario Kart. Source is the graphic engine created by Valve is used by Halflife 2 for example.

So Mario Kart Source is a modification for Halflife 2 which tries creates the well known Mario Kart feeling on your PC.
Apart from some pictures and videos there is nothing to download yet. But if you want to give the developers a helping hand, you can contact them on the Mario Kart Source Website.

pwned life…a battlefield 2 movie

There’s a battlefield 2 movie online for your viewing pleasure:

Kotaku writes:

“”The Pwned Life” apparently took a year to create and is voiced entirely by one man. It takes the form of a mockumentary on the life and times of a hardscrabble gang of soldiers, complete with soundtrack and interviews. Top-notch stuff and outstanding comedic timing.”

How to install Windows on an USB stick/USB harddrive

Think of the following: You are a developer and you want to set-up a second Windows just for the fun of it (and for testing, debugging, …) on your notebook for example. You won’t want to use the internal hard drive, because your beloved and 100 percent productive system is sitting there waiting for your boot-up. What to do? Well … swap hard drives? Use USB2 storage devices (hard disk, usb stick,…) and install the testing Windows?

“The Internet” (and the official Microsoft support) tells you this:

“Windows cannot boot from an USB drive. If your computer supports booting from such device, you can load a boot loader to the USB device which starts Windows XP from the HDD.”

Too bad is impossible. Well, is it?

“We will dump the contents of your original Windows XP CD , extract a few files from the Image using ISO modification software, edit the files, and put the modified versions back on the ISO. The resulting ISO image is burnt back onto a CD media, and can then directly be used to install Windows on your USB drive.”

Take a look at the complete “How-To Install and Boot Windows off a USB device”.

speed: play games as fast as you can.

There are gamers who don’t enjoy the games the same way the average gamer does. They are called runners. And they are doing Speed-Runs through games.

For example: the complete HalfLife 2 in 1 hour 36 minutes and 57 seconds…

And there is an archive to give you an insight on what is going on in the speed-run-scene:

“SDA is the home of speed runs done on many computer and console games. A speed run is a video of a player striving to complete a video game in as fast a time as they can manage. Sound easy? It’s not! A large number of tricks are usually used, possibly skipping whole areas of a game in the process, and there will always be mistakes.”

hands-off! unattended windows

Since Nico wrote some articles about the Windows unattendet installation procedure I decided to take a closer look. And you can too:

“Have you ever wanted a Windows CD that would install Windows by automatically putting in your name, product key, timezone and regional settings? And have it merged with the latest Service Pack to save time? Followed by silently installing all your favourite applications along with DirectX 9.0c, .Net Framework 1.1 and then all the required hotfixes, updated drivers, registry tweaks, and a readily patched UXTheme.dll without any user interaction whatsoever? Then this guide will show you how you can do just that! “
