ead of single layer traces covered by the paint, what about multilayer PCB? So the traces would be embedded between two FR4. This way it would be safer.

So, for the assumptions I made here, it’ll cost about the same amount of money out of your pocket to use electricty to propel your Niro and it does to use gasoline. If electric rates are higher than 15 cents/kWh (easily possible, at least here), then it’s more expensive to use the battery. There may good reasons to get the plug-in version of the Niro instead of the regular hybrid version, but saving money doesn’t appear to be one of them.

Larger motors used in rural settings and light industry may aswell use 400 voltage between phases by triangle connection. 3 phase 16A sockets are almost never seen in apartments, but are usually found from houses that have garage or other workspace with larger machinery. Larger 3 phase sockets are very common in farm setting and light industrial buildings. E.g. our hackerspace has air compressor that is fed by 3x 400V 25A line. It doesn’t even have neutral line, motor is connected to triangle and 24V for control logic is stepped down from 400V with transformer.

I’ll try to fix your old item if I can, but I might ask you to have a new replacement on hand just in case. Don’t skip the shopping trip because you’re banking on me being able to fix the old one. If it’s beyond repair, I’ll need to come back (and charge you) for a second visit once you get to the store instead of finishing the first time around, ultimately costing you more. You’re better off buying it and returning it if we don’t need it. Just don’t bother with these 32 home upgrades that are a waste of money.

On the Sony A33 and A55, the EVF can serve as both shooting and playback display. As mentioned earlier, the ability to check your shots and make camera settings without taking your eye from the eyepiece leads to a slightly different and more efficient shooting style; one that encourages you to learn the camera by feel and memory, rather than looking at the controls as you press them. I’ve only had a few days with the camera as of this writing, but can see that greater familiarity will produce a very efficient shooting style.

For a TRIAC I bend the middle pin forward 0.1″ – 0.2″, this is often done commercially and you can even buy them pre-bent.

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.

First, some background. I am a design engineer working on safety of life critical hardware design and technology development for a military application. I noticed this project a while back, and I invested some thought into how I would design the system.

Given my long-term dislike of EVFs, I was surprised to find myself as comfortable as I was with the one on the Sony A55 and A33. It by no means corrects all the ills of the genre, but does go a long way in the right direction. It still loses highlight detail in scenes with both deep shadows and strong highlights, but I found it workable most of the time. I could generally make out clouds against the sky, important for framing landscape shots. It also seemed to do pretty well under low light conditions, although as of this writing, I haven’t done a lot of night photography with the camera. Still, the large pixels of the Sony A33′s APS-C size sensor mean that its EVF is much more able to form a usable viewfinder image under dim lighting than is that of a typical digicam. Under really dark conditions, I’d still like to see it gain-up a bit more, though, even at the cost of slower refresh rates.

And this AC vs DC case when it comes to skin effect, is a reason for why some Data centers use DC distribution, as most server products uses switch mode power supplies and therefor has an internal bridge rectifier.

I’ve built a 24 V heated bed for my DIY (as I call it) Mendel 90 XXL printer (400 x 400 mm print area). I use a 24 V 400 W LED power source and – since I already had a 12 V RAMPS – put a 24->12 V DC-DC converter in line with the RAMPS and driving a 24 V heating mat (for cars) via a DC solid state relay. As long as it’s not too cold in the room I get up to 60°C which is helpful for PLA but of course not sufficient for ABS (but I don’t want to breathe these ABS fumes anyway)… I’d rather use a thick cable (in combination with an energy chain) than playing with mains voltage.

1) If not breathing, give CPR. Electrocution has pretty good recovery rates if CPR is started right away.
