 Bricking an e-cigarette

June 17, 2009

I’m impressed. Rossi a colleague of mine,  has managed to “brick” his recently acquired e-cigarette. There was this “magic blue smoke smell” in the office, and we were all skulking around trying to figure out where the smell came from until we saw him grinning at his table.

Apparently the bricking had to do with the multimeter he held in his hands and “measuring something” and “getting the vapourizer a bit wet”.

Hehe. I’m kinda impressed tho. Everyone knows any new electronic device needs to be “hacked” and prodded a bit.

 CanTennae: A cheap way to improve MyWireless signal strength.

November 19, 2006

A Cantenna is a homemade antenna using a coffee can, or even a Pringles can. These are typically called “WaveGuide” antennae since they guide/focus the waves.

This section will be expanded once I take some time to complete it. In the meantime, there are some pictures available here:  http://rodent.za.net/files/cantenna

Since MyWireless generally uses the same frequency as 802.11 kit, any 802.11 antenna design should suffice.

A lot of marvelous, yet highly experimental information about CanTennae is available at http://www.seattlewireless.net/index.cgi/DirectionalAntenna

This is what my Cantenna design was based off.

The best kind of antenna for MyWireless is a *directional* antenna, since it allows you to improve your return signal to the base station.

Cabling:

Cabling from your antenna is very important. You can calculate how much signall loss there is in the cable by using this calculator http://www.timesmicrowave.com/cgi-bin/calculate.pl

LMR195 seems to be used quite often, but over a 15m stretch of LMR195 you will lose 9db. LMR400 is more expensive, but over the same length will only lose 3dB
