This is a hands-on product review of the Anker “SoundBuds Sport IE 20” Bluetooth earphones and a hands-off bashing of the design of upcoming Apple AirPods. The $30 cost of the Ankers was an experiment, which turned into a rather useful purchase to accompany my iPhone. I explain why physics is the limiting factor to the performance of these products. …
Recently there was a security exploit identified in automotive keyless systems.
Normally, the car sends out an RF ping to the fob on a low frequency, to which the fob responds on UHF. If the system determines that the fob is nearby AND a hand is detected by a capacitive sensor, the car unlocks.

I did not expect to be posting this before my personal iPhone 4 arrived, but my friend Keith showed up with his shiny-new iPhone 4. We did a quick test in my office; this is not an exhaustive test, but it's a start.

But, I digress.
A couple of years ago, my good friend Dave and I were returning from an antenna mission down in Washington DC. We had already dropped off our rental car at Dulles airport and were in the shuttle van heading for our gate.
