And for the record, If I’m able to, I will breastfeed my children, because nutritional value, probiotics, and antibodies.

It will only trip the breaker if you have a bonded ground. Soil resistivity has everything to do with it, and is the reason most homes have bonded grounds (the soil resistivity is too high to provide adequate current flow to trip a standard breaker). Unless you have a GFI on that circuit you can still get shocked. Earth ground won’t help you until the voltage gets high enough to cause enough current to flow to trip a standard breaker, and NEC requirements set the limit on earth ground resistivity, the limit they set ends up equaling a voltage of 600 volts required to trip a standard breaker, and that is why most (single family) homes have bonded grounds. Earth ground is only for high voltage transients.

This is very dangerous. Safety regulations are all about keeping mains voltage away from people, inside casings that are earthed or double-insulated. This has the voltage just lying there. Possibly covered with a bit of silk-screened paint. It’s not guaranteed to kill someone, but for the extra money I’d sooner have a non-deadly heater for a 3D printer.

In the old days, we were always careful to remind readers to purchase a second battery along with their camera, but in recent years, battery life has become much less of a concern than it once was. Not so with the Sony A33, though: Unless you intend it only for light snap-shooting, consider the purchase of a second battery mandatory.

Does matter since he runs it on DC, even so the lamination are already welded at the factory, its how the transformer is assembled.

There are numerous safe ways to do this, without reinventing the wheel. Like so: http://www.omega.com/pptst/HCS_HEATER.html (Need 240 mains? Hook two in series.) Precision control circuit can be found in the Data sheet for LM34 temp sensor. Uses an LM10 combo op-amp/ref to switch a solid state relay. Doc

A lot of info: The Sony A33′s EVF display conveys loads of info, but the Fn menu items (shown here at the left and right edge) require a low eyepoint or eye movement to take in. (Image courtesy Sony USA.)

I know some policies that clearly state work needs to be performed by “duly licensed” personnel (ie. you better be a licensed electrician or plumber). That’s one of the reasons I did not want to install my own automated transfer switch. Insurance company would possibly deny coverage in event of a mishap.

Similarly in the Senate, Republicans’ slim 51-49 majority means that Flake’s defection could be enough to help sink a nomination, or at the very least trigger a tie-breaker. In the case of Farr, Democrats have mounted an aggressive push to block his nomination. Given Flake’s current stance, if they can convince just one more Republican to switch over, they could successfully take it down.

It should be possible. I used to have a heated tray for keeping my home brew beer and wine warm while fermenting. It was probably only about 30 degrees C but mains voltage.

Experts suggest buying an EVSE that can produce at least 30 amps of power. Generally speaking this type of unit would be able to add around 30 miles of operating range to a given battery pack per hour. Some EVs can get along with fewer amps, but buying more capability than you may need today makes the installation “future proof” should you eventually trade in the vehicle for a model that can handle the added capacity. However, if you’re planning on using a 30-amp unit you may need to upgrade the line’s circuit breaker to one that’s rated for at least 40 amps.
