Things Your Electrician Wishes You Knew | 19mm Momentary Push Button

I will state this categorically: No one should imitate this hack unless they have been properly trained as an electrician. Messing around with line power when you don’t know what you are doing (even if you think you do) is a recipe for death and disaster – literally.

What about converting down to 12-24v AC for the bed with a ZVC switch going to the controller? It seems that running it off DC is wasteful but mains is relatively risky.

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.

A final benefit of the EVF is that it lets you keep the camera to your eye during video recording, something no other SLR currently offers, although some SLDs do.

Mains powered heated glass plates are common place in catering, same deal as a car back window, the heating wires are on the other side from the “working surface” these things can tolerate touching and even fluid spills, why reinvent the wheel, the solution is already commercially avaliable.

The number on this photo is a little misleading. 337 mpg! I think I shot it after having the car for about ten minutes, nearly all of it without using the petrol engine. Still, it’s a nice little tease for any friends riding along.

MOVs are rated for specific ac-line operating voltages. Exceeding these limits by applying a sustained abnormal overvoltage condition could result in overheating and damage to the MOV.

You do in fact need to be a licensed engineer/electrician to design stuff with mains voltage, or you need to have your work inspected and signed for by one. It’s not just a matter of good instruction – it’s illegal for the regular Joe to even repair mains powered circuits beyond swapping a frayed power cord.

Knocking over a candle would be an accident. Keeping barrels of petrol in your living room would be negligence. Doing your own mains wiring without the proper qualifications, I dunno which side that falls on. Real accidents can’t be foreseen, but you have to take reasonable precautions.

I didn’t buy one, largely due to some compromises in the plug-in version. The very high load floor in the cargo area was a big downside for me, as it really limits cargo space.

In line with its stated goal of setting class standards “for best in class comfort and driving engagement”, the Corolla is 4370mm long, 1790mm wide and 1435mm high, with a wheelbase of 2640mm. That makes it 40mm longer and 30mm wider than the outgoing Auris, and 25mm lower. The obvious rivals are the Ford Focus (8mm longer, 35mm wider, 19mm higher and with a 60mm greater wheelbase) and the VW Golf (115mm shorter, as wide, 17mm higher and 3mm smaller in wheelbase.

“Main Power” means different voltage in different places. Where I am the mains is 240 Volts and circuit layout is not acceptable for this voltage. I doubt it would even be acceptable for lower Voltage.
