You need to factor in the kWh you used within the week (along with the cost per kWh). This will give people a better idea of actual cost to power this vehicle 253 miles.

You did reply to the Gurubuckaroo comment, just a few interjections managed to find their way in first. Does mess up smartarsed replies occasionally, shame when it’s a particularly funny one. On busy articles, I often find posts popping up between pressing “reply” and “post comment”.

The only place neutral is bonded to Earth ground is at your electrical panel, open it up and look at it. The white wires will all be screwed into a giant bus bar, which makes electrical contact with the electrical panel enclosure. All of the earth ground leads are also screwed into a bus-bar linking them all to Neutral.

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 can only think of a single instance in the last six months where the HPWC higher charge rate would have made a difference for us, and even then it would have simply made leaving for a long trip slightly more comfortable.

The real problem with mains voltages is that somewhere, some day, some bonehead will manage to fry himself – and the media will blame the maker movement for it. I’ve already seen far too many absolute beginners planning to wire up their home appliances to an Arduino as their first project…

Unfortunately, by in large, the comments for this article were unnecessarily negative, and downright factually inaccurate.

Yes, I have seen that sometimes (floating oscilloscope) but I always thought the good way would be to power the DUT through the isolation transformer and leave the oscilloscope safely earthed. Of course you sometimes need a bigger iso. transformer this way.

Potential starting relays consist of a high resistance coil and a set of normally closed contacts. The coil is wired between terminals 2 and 5, with the contacts between terminals 1 and 2.

I know this goes against what many of you have been told and understood your entire career, but take a deep breath and read on.

How about trying to say something accurate for a change? Almost everything you say lately is provably WRONG.

I’d love to see a follow piece on how to work with High Voltage as well. Lots of interesting projects to do with microwave and neon transformers…
