In Japan, People Get Charged Up About Amping Down | Lrd12 Overload Relay

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.

What we can say for now is that the new Corolla has taken a giant step forward, and that in terms of cabin quality and refinement, comfort and dynamic capability it is up there fighting among the very best. Likewise, you would hope, Toyota’s famed reputations for both reliability and customer service should continue to add credence for buying one.

If it is a three phase installation then there are four wires run. These are three phases and the star centre point or neutral.

While the Sony A33 and A55′s viewfinder display led to a bit of a learning curve for tracking fast action, its buffer-clearing speed is an ongoing issue. The A55 can capture shots with amazing speed, but once its buffer is filled, things slow down dramatically. The A33, for its part, has a smaller buffer, but it takes less time to clear. The most irritating point with the A55 was that it seemed to take forever before it would let me look at what I’d just shot. This is certainly more of an issue for a relatively inexperienced user than a pro sports photographer, but I often found myself wanting to check out what I’d just shot before the next action sequence started so I could note and correct for any problems in my shooting style. If I’d filled the buffer, though, it took upwards of 15-18 seconds before I could even view the first image on the LCD — and a good while longer before the buffer was completely empty and the camera was back to its maximum burst-length capacity. Shoot RAW+JPEG and it takes 32 seconds to clear a maximum of 18 images, while the A33 only captures 7 images and takes 12 seconds to clear. Advantage A33.

There’s one more multi-shot feature on the Sony A33 that’s worth mentioning; namely Auto HDR (High Dynamic Range). HDR photography increases the range of brightness values represented in a scene by combining two or more shots taken at different exposures, combining highlight detail from some and shadow detail from others. In the past, this has involved locking the camera down on a tripod, shooting several images at different exposures, and then working on a computer to combine them. Lately, though, the capability to do this directly in-camera has been appearing from a number of manufacturers, with varying levels of success. The auto HDR feature on the Sony A33 works pretty well, since the camera does the same micro-alignment trick it uses for its other multi-shot features. Options for HDR include an Auto setting, where the camera determines how much of the effect to apply, and manual settings ranging from 1 to 6(!) EV of exposure range.

Norm, remember your high school electrical classes, and don’t confuse the young ‘uns here. I’m sure you’ll recall that halving the current reduces losses (heating) in a conductor to one quarter: losses are proportional to the square of the current.

On Demand Refrigerant Safety Classes A2L and A3 have a very low GWP, making them a strong, long-term solution for many HVACR applications. However, these refrigerants are classified as mildly flammable and highly flammable respectively. This flammability class raises safety and compliance concerns. This webinar will help you understand these classes, along with the opportunities these refrigerants can offer.

We, uh, we don’t have sauna heaters down here. We have air conditioners In semi-related news, it was forecast to be 40C today…

I’m a bit disappointed, I thought this was a safe place for dangerous ideas. If you want to diy an ELV heat bed go ahead, but that isn’t going to suit everyone.

When I was a kid I built a Tesla coil using a 12kV neon sign transformer which my mom got for me (this was the 1960s, before Americans turned into wimps). At some point I had the transformer sitting on my workbench and plugged in, with nothing connected to the output. The corona discharge made a hissing sound, but I had music on and couldn’t hear it. Perhaps eight inches away was my table radio, which had a metal chassis. I reached between the two to get something, and my arm shortened the air path enough for an arc to form. I had a couple of nifty burn marks (entry and exit) for a few weeks.

I would prefer, use a circuit (SCR?) to lower the voltage to around a safer value, where we won’t have any problem in the worse case.
