The other advantage is, if your system needs to go into debugging, you can still use the included remote for a manual override. AKA your family won’t kick you out of the house and never let you bring an invention inside again.
For all my complaining about the difficulty of tracking sports subjects and the dead-screen issue, though, the difference between these SLTs and other consumer-level DSLRs is little short of astonishing. It may not be a direct substitute for a Canon 1D Mark IV or Nikon D3s, but if you have a budget of under $1,000 and shoot any fast action at all, the Sony A55 and A33 are hands-down slam-dunk purchase decisions. At this point, there’s nothing else in the large-sensor segment of the digital camera market that remotely approaches their high-speed capture capabilities.
15A is more like 1,500 times what’s required to kill you, depending on what part of your anatomy it finds to traverse.
I will tell you guys how to dim lights with relays, but first you have to tell me how you dim them when using a zero cross detection optotriac.

The one negative that most stands out in my mind for the Sony A33 actually has the least to do with its abilities as a camera. The first thing that comes to mind when thinking about shooting with it isn’t whether I’ll be able to bring back the shots I want with it, but rather whether the battery will last long enough to do so. We have no doubt that the Sony A33 will meet the fairly generous shot-life numbers quoted under the CIPA specs (340 shots with the LCD, 270 with the EVF), but in actual practice, with the camera rattling off hundreds of shots in amazingly short order, what most struck me was just how fast I seemed to run out of battery life. It’s quite easy to run through a full battery in just a couple of hours of active shooting, and two batteries should be considered a minimum for a day of serious shooting.
The second upgrade to the Sony A33′s LCD is the TruBlack technology we first saw on other recent Sony cameras. This is a combination of anti-reflective coatings and a darker mask around the LCD pixels, to keep shadow areas darker. It does seem to be an improvement over LCDs lacking it, but to my eyes, the difference isn’t dramatic.
Given my long-term dislike of EVFs, I was surprised to find myself as comfortable as I was with the one on the Sony A55 and A33. It by no means corrects all the ills of the genre, but does go a long way in the right direction. It still loses highlight detail in scenes with both deep shadows and strong highlights, but I found it workable most of the time. I could generally make out clouds against the sky, important for framing landscape shots. It also seemed to do pretty well under low light conditions, although as of this writing, I haven’t done a lot of night photography with the camera. Still, the large pixels of the Sony A33′s APS-C size sensor mean that its EVF is much more able to form a usable viewfinder image under dim lighting than is that of a typical digicam. Under really dark conditions, I’d still like to see it gain-up a bit more, though, even at the cost of slower refresh rates.
At the time I tried to get the regulatory authority in NSW to do something about it. Zero interest. Useless idiots.
I can’t think of any good reason for a toggle switch to get hot. If I ever found a hot toggle switch, I’d call that a fire hazard and recommend repair.
You have right, a isolated SMPS is used. The Microchip solution presented above will not work properly because of the ESP Module power requirements.
I suppose if you want, you can stick your fingers into the toaster slot to touch the exposed element and push down the slider or try to make toast while taking a bath. Otherwise, you are not making any contacts with the high voltage.
