Measuring Average DC Current
2012-05-22 11:56:00
I would like to know the fastest and most convenient way to measure the "average DC current consumption" on low current (0.1mA ~ 500mA), low voltage (1v ~ 14Vdc) devices. For example, let's consider a 2-way remote for a car alarm system. The RF components in such a remote use power cycling to increa

Cyprus property market 'struggling in current economy'
2012-05-07 02:00:00
Board member of the Royal Institution for Chartered Surveyors (Rics) Cyprus Pavlos Loizou has said the economic situation in the country is impacting the real estate sector. Speaking to the Cyprus Mail, he stated: "Property and rental prices continue to drop, mainly due to the unfavourable economic climate, the negative forecasts for the broader economy, the lack of sponsorship and the low performances [of real estate assets]." Mr Loizou explained Cypriot commercial property yields need to improve and rents have to stabilise if investors are to be encouraged back to the country and he stressed until this happens, the market will remain in a "slump".  Meanwhile, Cyprus Property News revealed the rate of construction in the nation slowed in February, with 9.4 per cent fewer building permits issued this year than in the same month in 2011. The figures from the Cyprus Statistical Service also showed the total value of construction projects in January and Feb...

Keith Olbermann, David Letterman: War Of The Poseurs
2012-04-04 14:12:00
Fired Current TV terror Keith Olbermann to David Letterman Tuesday: ?If you buy a $10 million chandelier, you should have a house to put it in. Just walking around with a $10 million chandelier isn?t going to do anybody a lot of good, and it?s not going to do any good to the chandelier. And then it turned out we didn?t have a lot to put the house in to put the chandelier in, and we didn?t have a building permit.?TIME magazine's James Poniewozik:  "Olbermann set himself up with that analogy, because where it naturally leads is: if you have millions of dollars to spend, spend it on building a great house, because when it comes down to it, the house is way, way more important than any chandelier. I?m not sure if Olbermann would want to extend the metaphor that far."Mediaite:  " . . . leaves out the fact that the chandelier also had a stake in the house, and could have gone easy on the Swarovski for the greater good, Olbermann pretty much lets on that he never intended to put...

He and they will say that this time it will be different, and it may be. Just don?t expect him to be part of the team."RE:  Olbermann's refusal to anchor Republican presidential primaries.  Olbermann loathes Republicans to the point where he is unwilling to cover these contests, much to the chagrin of Current TV suits.
