Cooking Triac? In my experience there are only good Triacs and bad Traics. You can tell the bad Triacs because they usually have a a little bit of plastic encasing still attached to the three legs after they have exploded.

If you wrap your own coil, consider wrapping a thermistor or thermocouple into the windings. Insides may heat up before outsides. Expoxies have limits. You don’t want failure halfway up 50 stories, whether mangni-shoes or a load of pig iron.

While I found enough to quibble about to justify my role as a reviewer, I also found the Sony A55 and A33 to be uniquely compelling cameras. The most telling point was how hard I found it going back to an "ordinary" SLR after just a day of shooting with the A55. I’ve long been an avowed EVF-hater, but the viewfinder display on the Sony A55 is good enough that I found myself sorely missing it when I returned to shooting with a conventional sub-frame SLR with a typically small optical viewfinder. The Sony A55′s shooting speed matches that of professional models costing literally thousands of dollars more thanks to the unique pellicle mirror design, and its uniquely Sony features (Handheld Twilight/Multi-Frame NR and Sweep Panorama modes in particular) take the A55 places no other SLR has gone before. I was also pleasantly surprised by how comfortable the Sony A55′s grip was, given the tiny body size. I still prefer having more to wrap my fingers around, but this is as good a grip as I’ve seen on an SLR body this compact to date. While its primary target clearly is not the entry-level shooter, the Sony A55′s Auto+ mode takes it closer to true "just push the button" simplicity in auto mode than any other camera we’re aware of, enabling novice-level users to enjoy the multi-shot and other Scene modes without having to worry about which to use when. At the other end of the spectrum, for the enthusiast with time to become acquainted its capabilities and familiar with its quirks, the Sony A55 expands the realm of amateur photography further than any SLR to date. In the A55 and A33, Sony has used outside-the-box thinking to deliver a uniquely capable, functional, and well-designed SLR. Hot on the heels of their category-redefining NEX-3 and NEX-5, Sony’s engineers have now likewise redefined what consumers can expect from an SLR.

Did you keep records so that you actually know you repaired 15,000 TVs? I don’t believe it, and if it is not true then I doubt your other statements on this evidence alone. People should classify their statements as to fact, fiction, or opinion, not just leave them in an ambiguous interpretive limbo.

Why not use a silicone pad block heater for cars? You glue them on, they run on 120v and work good. It’s robust enough to sit on the bottom of your engine, in elements and gravel spray from the road, for years. They even come with a little tube of aluminum adhesive. Seems like a pretty good fit.

DC burns. It doesn’t cause a muscle lock-up like AC does. It’s more dangerous in that sense, because you don’t feel it beyond the initial shock until your flesh starts to cook from inside out.
