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.

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.

Many thermostats are battery-operated, and once they power down so will your air conditioner or heater. Check that your thermostat is fully operational and the connections to the wall are good.

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.

Overall, there’s little question that the Sony A33 has the best video AF of any interchangeable-lens camera currently on the market, but if you plan on doing much video recording, I’d suggest you also plan on buying an accessory external microphone to record the audio.

But my toaster uses heating elements contacted to 120 VAC, and so no barriers against ignorant ding stupid things. I agree the lower voltage is use because of the illusion of safet is probably why they use the lower voltages. Only an illusion to those who haven had the opportunity to study electricity or had made the effort to study it.

The control circuit for the 12V/24V can be as simple as a MOSFET and don’t even need to be isolated if you know what you are doing. Because you are using a regulated supply, the same heated bed can be used at different countries with different voltages. The safety regulatory stuff get you covered as 12/24V are considered to be low voltage.

A hobbyist should not screw with a Triac on house wiring if it will be “permanently” installed in a junction box. Make an adapter that plugs into a socket on the outside so that it is clear it is not a normal outlet. If you have to homebrew something like this use a good relay or contactor with a UR approval. AND read the spec on it thoroughly.

I came here to post those two points! The corollaries to 1) are that should something go wrong, you have a chance if there is someone else there who knows CPR. I like mandatory CPR training for lab workers because of this. AEDs are good too. Rules against playing with things that can shock you while working alone are also good, but much harder to follow–I’ve spent decades working alone in research labs. CPR fails way more often than not, but electrical shocks are an important exception to that rule. And you almost got the extra credit for correctly spelling arrhythmia.

> those who haven had the opportunity to study electricity or had made the effort to study it. Can’t let Darwin wipe them out when they happens to the target market… Even worse is that there are people that want to build printers on their own, but are not qualified to wire stuff to line voltage safely.
