Hotspot Project

One of the hobby projects I’ve been working on these last few weeks, is a wireless hotspot for the multi storied apartment building, my Dad Manages.

There were lots of offers by various companies to setup and maintain this sort of thing, but most of them involved a revenue sharing system that had fairly large setup fee’s.

So I investigated the possibility of setting it up ourselves, and last week, things finally went live.

The setup includes:

  • 2 * Linksys WRT54GL routers running CoovaAP ($115 each new off Ebay)WRT54GL internal
  • DLink PoE Adaptor ($70 from a local wholesaler)
  • 2.4GHz ComTenna ($100 from CityTechnology.com.au)
  • 1M of weatherproof Cat5E cable ($20 for 20M from freenet antennas)
  • Cat5E extension from reception to 2nd floor (installed by certified Electrian: $550).
  • Monthly fee for Worldspot service of about$15.00.

The WRT54GL’s are setup in bridged mode (i.e. the one outside, where most people will get access to, has its cable plugged into a LAN port, and at the other end is plugged into the LAN port of the master WRT54GL (which has access to the Net).

We now have wireless access with a signal strength of between 30-50 dB in each room (60+ rooms over 6 levels). The signal goes out to Malcolmn street too, so you can actually get a signal of about 15db from Parliament House, if you like, yes, I tested this for fun ;)

The property gets 100% of the revenue, and this equipment should last at least a few years.

None of it would have been possible, without the the Linksys WRT54GL Wireless Router and CoovaAP firmware.

Super Tuesday 2

Screenshot of Super Tuesday 2 results As some of you would know by now, Hillary Clinton has surprised most, and won just about all the primaries and caucuses voted for today in the American states of Ohio, Texas, Rhode Island, and Vermont. It’s a pretty big come back for her, since Obama had won the last 12 or so, states in a row, and he was therefore expected to win these. Overall he’s still ahead slightly, but this still means the Democrat nomination is still up for grabs, and we probably won’t have a nominee for a few more months, until the remainding states vote, and the eventual decision of primaries and their superdelegates, vote. Check out the scorecard over on CNN.

Current Presidential NominationsThis really sucks, because, while this is happening, McCain (Republican Nomination winner) can prepare and focus his efforts on the presidential election in November. And we all know where another republician president will lead the world.. into a war with Iran, into a more unstable US currency and US economy, and eventually the fall of an empire that has and currently keeps the world pretty stable, as its the only super power.

Update 12/03/08: It looks like Obama has actually ended up winning the state of Texas, as he won more Caucus Delegates - full explanation here.
