Sony MHS-PM5 bloggie HD Video Camera (White) Review

Several people complained on various internet review boards about how this camera does not deliver very high quality video, etc. I'm a technology enthusiast, computer specialist, amateur photographer and have about 7 or 8 different cameras - so I feel qualified to give a good review.
This is a camcorder meant for internet uploads/sharing, quick shots, etc. This is not what you want to film your wedding with. So don't expect broadcast quality.
Having said that I think the image quality is VERY good for its size. One huge advantage over Flip/etc... is the swiveling lens. This was the main attraction for me. I'm always embarassed waving a big camera in public. Just don't like when people stare at me for filming something. This is why Sony bloggie is a great product. You can turn the lens to an angle you like and hold the device like your cellphone. People will actually think you are just playing with your phone.
Let's get done with my complaints list quickly:
-CMOS sensor - means you get the rolling shutter a.k.a jello effect when panning too fast with the camera (vertical objects appear skewed)
-Smaller lens angle when using 1080p mode. (i.e. picture is too "tele")... you get a nicer wide angle if using 720p.
That's about it, image quality -especially in daylight- is very very good for such a camera. I actually prefer to record in 720p 60fps mode, the high frame rate gives it a very smooth motion.
FYI, it's compatible with Apple's iMovie. Will take some time to import your videos but once it's done, editing is super easy!
I hesitated for a long time before buying this camera but I'm glad to say I don't regret it at all! Very satisfied with my purchase.

USB 2 Channel PC Oscilloscope Review

I have really started to like my scope. At first it took a little getting used to since the controls are a bit different from a hardware scope -- but now it is my scope of choice on the bench except where I need the wide bandwidth of an analog scope. The hardware is supurb -- it is accurate and the triggering is excellent. The best feature, of course, is its ability to show what happened BEFORE THE TRIGGER which is great for catching the glitches that caused the trigger event.
The spectrum analyzer is OK once you understand that there is not low pass filter so that signals that are above the high frequency cutoff alias into the inband display. It could have log displays etc, but for the dollar it's a great value.
The transient recorder looks good and is a unique feature that I haven't had occasion to try yet.
The scope installed quickly and ran the first time on my windows XP and VISTA machines. The two probes that are supplied are great quality and very similar to the TEK/HP probes we are all used to.
My only criticism is that while the software user interface is quite usable, it's a bit clumsy and was probably written some time ago and never updated to act like more current interfaces. The online documentation is a bit weak and could use some improvement and the hard copy is very basic. But, as I said, the scope is quite functional after you get used to the interface.
While it isn't quite as good as a $5000 TEK digital scope it sure gives plenty of bang for the buck.
I'd buy it again in a minute.
