It’s OK, you can admit it — from the time you first saw those huge electromagnetic cranes in scrap yards you’ve wanted to have one. While it may not fling around a car, parts donated from scrapped microwaves can let you build your own electromagnetic lifting device and make that dream finally come true.
That said, why not use 12v halogens (or even mains voltage halogens) to provide the heat? They are ~99% efficient at that, cheap, plentiful, universally available…
Level-2 isn’t required for charging at home, but it sure makes life a lot easier. I wouldn’t use or recommend using a standard outlet for Level-1 charging unless it’s a dedicated circuit with it’s own breaker. With the larger battery packs these days Level-2 charging is becoming more popular if not necessary. Consult your electrician, but I personally think pulling wiring that will handle less than 50 amps is a waste of time. You can use a smaller circuit breaker, but the wiring needs to be robust. Most modern homes built in the last 10 years or so should have a 200 amp panel anyway, so you aren’t going to notice an EV plugged in. Again, consult a qualified, licensed electrician. Also, before you let your ‘handy’ brother-in-law install your charging station, be aware if there is a fire from improper installation, your home owner’s insurance will most likely NOT pay for the event.
While no standard is perfect, I have found that knowing the NEC and looking carefully at manufacturer listings and labels can save you time, your customers money, and help keep everyone safe.
Where I do agree that it is under rated, as far as I know, Mathias is an electrical engineer. So he should be able to work with mains, and he should also know better.
So China are stuck before capitalism’s stable period, the West are now past that. China might end up passing through it, or skipping it altogether. Actually the West might end up learning a few tricks from them.
Gasoline-powered portable generators, which cost from about $400 to $1,500, based on their output and features, are not only readily available at home-improvement stores, they’re easy to use. “If you can operate a lawn mower, you can operate a generator,” says Art Aiello, spokesman for Generac, one of the largest manufacturers of portable generators. “In winter, it doesn’t take a lot of snow or ice to bring down a power line in certain neighborhoods. If you have the ability to pull it out, add fuel and attach extension cords, a portable is a sound solution.”
Before we begin, we must begin with an obligatory disclaimer: handling mains voltage can be very dangerous. Do not do so unless you are qualified! You could burn your house down. (Without the lemons.) That being said, [TJ] has created an interesting dev board for controlling mains voltage over WiFi with the now-ubiquitous ESP8266 module. At only 50mm x 25mm, it is easily small enough to fit inside a junction box!
> and some apartments are fed with 208V 3-phase, which provide three phases of 120V to neutral, or 208V phase-to-phase.
The Sony A33 offers a lot of control for shooting contrasty subjects. Dynamic Range Optimizer (DRO) adjusts contrast and brightness to optimize the camera’s use of available dynamic range. Auto HDR modes use three quick shots to cover an amazing tonal range. (The shot on the right represents the maximum range of 6 EV.)
So if I am looking to make the magnet more powerful, other than supplying more current, could I wire the primary and secondary coils of the microwave transformer together in series to get more turns (being mindful to keep the direction the current flows the same in both coils)? My thoughts are that it would increase the resistance a bit from the added wire but that the magnet would have a lot more turns. Am I missing something or am I onto something? Thanks in advance!
The run and start capacitors provide the phase shift for starting torque because their capacitances add up when wired in parallel. In fact, both capacitors are wired in series with the start winding and in parallel with the run winding.
