I did numerous formal sponsored video interviews on Tues morning which are now live on our Online Show Daily. But I came across a couple of other interesting demos during the show and took a video of a couple of them with my cheap but convenient Flip video. Below is a Keithley demo showing their new Vector Network Signal analyzer (just turn the volume up).
Another interesting product that is very cool is the laser etching machine from LPKF which can in seconds etch a metal pattern into a substrate like a PCB or ceramic board. It etches the pattern by scoring the surface and then heats the surface to peel away the metal which is removed by an air knife. It can do both prototypes and low volume production so it is versatile.
