Hopefully one of these days we’ll go to significantly more DC distribution all over teh place, but I often wonder if I’ll see it in my lifetime. I thought I was imagining things when I was trying to remember if Japan was 50&60, but that’s pretty fascinating.

You probably think OSHA is staffed entirely by millennials who have no idea what it’s like to lose a limb and act like it’s a big deal or something.

And keep in mind that EVSEs are a continuous duty device. As such, you need to derate them from the circuit’s rating by 20%. So you should only use 12A on a 15A rated circuit. And you should only do that if you’re confident that there’s nothing else pulling significant current on EITHER circuit besides your EVSE.

If Handheld Twilight and Multi-Frame NR modes are practical, Sweep Panorama is just plain fun. I’ve always been a fan of panoramic images, and spent more time than I care to remember back in the film days slicing and splicing together 4×6-inch prints with a razor blade and rubber cement, to make panoramas from sequences of individual shots. The Sony A33 and A55′s Sweep Panorama mode does all this for you inside the camera. Again taking advantage of Sony’s high-speed capture technology, Sweep Panorama collects dozens of individual images while you hold down the shutter button and "sweep" the camera from side to side or up and down. The powerful Bionz image-processing engine examines all these images, takes slices from each, applies geometric and tonal corrections to each slice, and then stitches them together into a single panoramic image. The results are stunning, and experimenting is loads of fun.

The other advantage is, if your system needs to go into debugging, you can still use the included remote for a manual override. AKA your family won’t kick you out of the house and never let you bring an invention inside again.

But Mike I would gladly clean under your stove for around 3kW of free power… Ahh ok so his parent’s don’t have a 220/240 outlet, makes much more sense now. In that case its a purpose driven hack, elegant in its simplicity.

I don’t specialize in installing dishwashers or washing machines, so please don’t call me about them. You’re better off finding a plumber.

Meh, just use a relay for your “PWM”. It’s much easier, and you have a huge low pass filter. You can easily go up to a few Hz switching with a good realy. Use a solid state relay and it’s even better (you might break your mechanical relay after prolonged use).

Creepage to the mounting screws is one issue and that fuse crowed by traces at mains potential is just bad design.

The Model 3 is showing 118V @ 12A which is 1.4kW. The same screen shows 1kW/hour being added, but it is rounding down. I need to take a 8 or 10 hour session and total up the numbers.
