These were obviously mistakes. I would never intentionally come into contact with HT from the anode cap.

I had my poke. Mostly people saying “may” or “could” invalidate your insurance and advising caution. Which is sensible enough. Also mention of laws mandating a professional installing things like new wiring for cookers, and other kitchen / bathroom stuff. Makes sense since there’s water about. This is the UK that I looked up, since that’s where I live. Our electrical standards are pretty high, mandatory ring mains, limits on spurs and wiring length, and even our mains plugs have half a dozen safety features built in (protection against the agony of accidentally stepping on one not included).

AC is safer than DC. You can let go of two AC terminals but not DC as DC keeps your muscles clenched. AC doesn’t.

Translucent (pellicle) mirror. Undoubtedly the biggest story of the Sony SLT-series cameras is their use of a translucent mirror. Also known as pellicle mirror, this works by allowing most light to pass through to the imaging surface beneath, while a small portion is reflected for other purposes. Sony is not the first camera manufacturer to use a translucent mirror in an SLR-style camera, with the manual focus Canon Pellix film camera from 1965 taking that credit. The Pellix was followed by a handful of other pellicle mirror-based SLRs from Canon, Nikon, and Mamiya, largely designed for professional photographers, and manufactured in very limited production runs. It wasn’t until 1989′s Canon EOS RT that the first autofocus pellicle camera was released, followed by the EOS-1N RS in 1995. Fifteen years later, Sony has become the first company to resurrect the pellicle mirror for use in an interchangeable lens digital camera.

The only thing I would add would be a (redundant) circuit breaker (Airpax, Heinemann, et al) on each input that was two-pole with a common trip bar. That, and I would build it in a metal enclosure.

“OK, you hold that small bulb across that plug, I’ll connect this 9v battery across the live & neutral pins…”

I was mainly thinking about the diff between high vs. low RMS AC voltage but the discussion of AC vs DC has been interesting as well.

Still, the orderly May backdrop registers as bullish, versus the prior three months, punctuated by the S&P 500’s flag pattern pinned to the steep early-month rally.

Anyone that knows me really well, especially family members, is surprised/amazed that I’ve managed to be over 50 and still more or less bilaterally symmetrical, without too many visible scars.

I know a lot of people that have never heard about “makers” but I wouldn’t trust them near any mains wiring – like my own dad who has wired a circuit breaker between live and neutral. Only the ensuing BANG and my mom’s swearing and yelling from the now dark kitchen have disabused him of the idea that that is how it should be done.
