Interactive Panoramas, For Free!

Posted July 5th, 2011 by Shawn

So you've seen Panoramic Pictures, you've even found some on websites that are interactive! But alas when you've looked into the program that creates them, its been expensive and difficult to create.

Well no more! Microsoft have added some functionality to their FREE Panoramic stitching utility called 'Microsoft ICE' (Image Composition Editor), which now lets you export into a format called 'HD ViewDeep Zoom'.

This allows you to create an html webpage in which you can view your panoramic image interactively.
Microsoft also give you the code to embed your Interactive Panoramic Image into another webpage... like this one!
(Note: You will need to download the HD View plugin to see these, you will be prompted when you load the image)

For better viewing, adjust the following: (I Personally pick the last option)

Tone Adjustment:

There are three tone adjustment modes. You can switch between modes with the following icons in the upper right corner of the screen or by using the 'T' or 'shift'-'T' short-cut key.

No Adjustment
Exposure Only Adjustment
Compress or Expand the Dynamic Range as necessary


So I present a couple of Interactive Panoramic Images from two of our Sites on Air-Stream. I have many, many more Panoramic sets from the sites over the years... but here is a teaser to get you excited :)

R100 Wifi WebCam

Posted February 13th, 2011 by ross

Have wanted to set up my R100 as a webcam server and finally gave it a go when a mate wanted to use his to monitor his business premises.
OpenWRT runs great on them but apparently the 2.6 kernel is broken on the units with regard to wifi but if you want to use a webcam the 2.6 kernel is a must.

Anyway I found forum reports in which people reckoned it was working and long story short me too...

Install OpenWRT to your R100:

• Pull the power plug, press and hold the reset button, plug power to the device and wait until the PWR LED starts flashing slowly (almost immediately). Now release the reset button and upload the firmware by TFTP using the following commands
sudo arp -s 192.168.1.1 xx:xx:xx:xx:xx:xx


How-To: Setup Air-stream at home.

So you want to get on Air-Stream? Great! Here's a little How-To for getting yourself connected to the network.

All Air-Stream connections are made up of 3 essential parts:

  1. Some Wireless Gear
  2. A Pole or Mast to mount the gear
  3. Cabling back to your own network and power

In this guide we'll cover these three basic items as we walk through how Air-Stream-Modbury-North was setup from scratch.

There will also be a rough costing listed for how much everything cost to give you a realistic idea on what it costs to connect in.

Parallel Port (LPT) Remote Control

The aim of this circuit is to enable a system script to reset or power cycle an AP or router when they crash or lock, which does happen from time to time. This is very usefully where access to a site is limited.

Nevertheless the same circuit could be used for any remote control project where you need to switch on and off a device using a computer.

The following circuits are drawn out in such a way that it can be easily assembled on vero-board.

The design allows from 1 to 7 relays to be used.

The download link for two different versions are as follows:

One Relay: http://www.air-stream.org/files/1_channel_LPT_0.pdf
Seven Relays: http://www.air-stream.org/files/7_channel_LPT.pdf


Power Over Ethernet (PoE) Building

An Ethernet Wireless Device is a very practical approach, mainly because they can be located near the Antenna in a waterproof box and the Ethernet cable can be run a fair distance away up to 300 metres in some cases.

Ethernet connections require only two pairs of cable TX & RX, but in a standard Cat5e cable there are 4 pairs. This allows for the spare pair to used for injection of power over the Ethernet. Called Power Over Ethernet (PoE) it is common practice to use the Blue and Brown pairs for this purpose.


OpenWRT and Quagga For Dynamic Router

Adding Quagga to OpenWRT for Dynamic Routing

Read up on http://quagga.net

Get your AS number for your AP and neighbours from the committee

Install Quagga

ipkg install quagga
ipkg install quagga-zebra
ipkg install quagga-bgpd

Configure Quagga

vi /etc/quagga/zebra.conf
vi /etc/quagga/bgpd.conf

Add PID files

touch /var/bgpd.pid
chmod 777 /var/bgpd.pid
touch /var/zebra.pid
chmod 777 /var/zebra.pid

Check Init files

/etc/init.d/S35quagga

OpenWRT Kamikaze Build

Building your own OpenWRT firmware from SVN: Kamikaze

Using OpenWRT from the the downloads.openwrt.org means you are bound to a slow release and testing cycle: White Russian RC6 is the most current release at time of writing

This means that you are stuck with an older kernel 2.4.30 and older builds of the software that is based on that kernel

Also the configuration and management system is a generation behind

The alternative is to use Kamikaze, this is downloaded from a developers site

Anybody with some basic programming skills and some linux experience will have no trouble building the source directly from the Subversion Repository

Take this guide as a glossary, refer to https://dev.openwrt.org/ as your bible
