Video capture is an area where the Sony A33′s translucent mirror technology makes a huge difference relative to pretty any other SLR currently on the market, and relative to even fast-focusing SLDs. Every other interchangeable-lens camera currently on the market either doesn’t autofocus at all when recording videos, or has to resort to slower and/or more obtrusive contrast-detect focusing. Because the Sony A33′s phase-detect AF system is always looking at the subject, fast autofocus during video recording is no problem.

But who cares, there are plenty of (approved) lightning dimmers that are for replacing teh regular wall switches and they are usually *not* capable of dimming 2 KW loads which is the full capacity of a regular outlet. But rather just a few hundred watts, enough for its intended usage.

Personally, I find Handheld Twilight mode to be one of the most useful camera features I’ve seen in recent memory. The freedom to shoot handheld under dim lighting is enormously liberating, opening up lots of photo opportunities that I’d have had to pass on previously. It’s the reason I frequently grab a Sony camera for snapshots when I’m going on a personal outing.

Translucent mirror (redux). As noted previously, adopting a translucent mirror design has allowed Sony important benefits in terms of autofocus, burst shooting, and body size, and conceivably the removal of one more mechanical component could improve camera reliability, as well. There’s no such thing as a free lunch, though, and the translucent mirror design does have some clear disadvantages as compared to existing SLR and SLD designs. Perhaps most significantly, light entering the lens is shared between the autofocus and image sensors at a fixed ratio. In the Sony A33, about 70% of the light makes it to the imaging sensor, while 30% is reflected to the autofocus module. With a traditional SLR, all the incoming light arrives at the image sensor once the mirror is raised, and the same is true of an SLD camera whenever its shutter is open. With less light arriving at the sensor for an equivalent aperture, a translucent mirror camera must either lower its shutter speed, raise its sensitivity (and along with this, the levels of noise, or the amount processing to mitigate it), or some combination of both. An increase in sensor gain to compensate for the loss may explain why we see slightly higher noise levels from the A33 versus the A560, which share the same sensor.

The leads on that TO220 case SCR and that solder trace are not going to handle 20 amps continuously without heating up. A SCR that’s up to the task of carrying 20 amps for hours on end would have a TO-218 case or even be stud mount. If all else fails you could just use a contactor relay which is what they normally use for this application.

The rear seats are nearly as roomy as the fronts , which is an incredible achievement for such a compact car. Never did the kids knee my seatback.

I’m constantly amazed by the use of a giant blob of solder to increase the cross section of PCB traces meant to increase their current carrying capability.

You now have a Tesla 3 correct? What is the efficiency hit by using 120 volts? It used to be a 30% hit for the S,X, Roadster, and new Rav4Ev with the Tesla drivetrain, Meanwhile 12 amps at 115 for a VOLT is quite efficient.

2) If breathing and everything seems fine, there can still be some arrythmia that will manifest only hours later. It is a good idea to visit a doctor for EKG readings, or at the very least have someone monitor you for the next few hours and if you go unconscious, be present to give CPR & call ambulance.

my first “real” job was in a video game arcade back in the 80’s my boss was a really cheap prick that used to buy asian cocktail machines that were “native” 110V, with a 240V to 110V step down transformer wedged in where it would fit, my second day I was fishing out a 20 cent coin that had missed the coin box, I got “zapped” hard enough to blow my finger nail in half and stop my heart.
