Good explanation. I think italian food is incredibly better, but the way they treat you in Italy leaves a lot to be desired. I remember in the old days pre-Euro, that we exchanged USD to all sorts of currencies and only in Italy we felt they were trying to always get the best of us... We had similar negative experiences in the Czech republic some 3 years ago.

You must be smoking some really serious weed. I have yet to see (in the US) any medical doctor who is not in the top 10% of income of the country (at the very least!). Get a specialization and you are easily in the top 2%. All of this "insurers set prices", "having to pay the lights" is complete BS. They see you for 6 minutes because they can... that way they can see 10 patients/hour and make 200-500 k$ salaries. Compare that to any other highly qualified professions (at > 10 years education) and you see that they have a pretty sweet deal. If this were not the case, you would not see so many applicants to medical schools, eh?

Let's see... a tire with a radius of ~0.3 m, in a car traveling at 100 mph ( 45 m/s) experiences a maximum centripetal acceleration of ~6700 m/s^2). A 1 in^2*0.5 in piece of rubber (assuming density to be ~ 1 g/cm^3) experiences a "centrifugal foce" of ONLY ~4.7 pounds! That is only 4.7 psi. So over-inflating by 20 psi MAY BE A PROBLEM.

xprotolab or teensy 3.1

Check out xprotolab (http://www.gabotronics.com/development-boards/xmega-xprotolab.htm) from Gabotronics. Not too fast or too easy to use but it is very capable and Gabo provides very good support. It is self-contained (small oled screen) but can also send info to PC over USB.

Also, the "arduino" teensy 3.1 could be used to make a USB-based scope for ca. $20 (plus some additional parts) and can have a lot of other cool uses too. Check it out: http://www.pjrc.com/teensy/tee... and http://forum.pjrc.com/threads/....

Your posting is close to non-sense. Who is saying that every Cessna 172 should have this device? We are talking about AIRLINERS, and in particular those that go transoceanic routes where radar tracking is not possible. On a 767-sized plane (and above) the $100k cost IS negligible when compared to other operational costs (fuel, crew, maintenance, insurance).

I am not talking RADAR, but rather satellite-linked transponders relaying (at least) once per minute the plane "vitals" (coordinates, velocity, altitude, attitude, cabin pressure and temperature, fuel levels, any error codes or warnings). I mean, this may not be cheap, but it is meaningless cost-wise compared to the operational cost of a plane.

In order to get a loan you must first prove you don't need it.
