The best tip for buying a portable home generator: Don’t wait until the lights go out. Whether you live in a place at the mercy of snowstorms, hurricanes, heat waves or an outdated electric grid, a power outage can range from an annoyance to life-threatening.

In reviewing my experience with the Sony A55 and A33, it’s interesting to find so many of my notes and so much of my attention directed to the viewfinder display. Were I not already so familiar with Sony’s multi-shot exposure technology, the camera’s multi-shot features would doubtless have commanded more of my attention, as they’re worthy features indeed. That said, though, the viewfinder turned out to be absolutely integral to my experience with the camera.

It’s a Prius for private buyers. It’s got one of the best drivetrains and most sophisticated chassis in the class, looks ok inside and out, no doubt usual exemplary quality and reliability.

Once upon a long ago I was tuning a Tesla coil I’ve built with a friend. The coil was driven by a dirty cheap spark gap made with a screw that had to be rotated to change the distance between electrodes. I had to switch off the 6kV primary transformer, ground the terminals and rotate the spark gap, repeating this procedure until the biggest possible spark jumped out of the coil. After repeating it many times, I accidentally forgot one step. I’ll never forget that moment. My arm was thrown in the direction of the wall as if it had its own will and wanted to get through. Not good. Very painful.

The number on this photo is a little misleading. 337 mpg! I think I shot it after having the car for about ten minutes, nearly all of it without using the petrol engine. Still, it’s a nice little tease for any friends riding along.

Gardner Minshew II threw two touchdown passes and ran for another score and No. 12 Washington State stopped No. 25…

I used a bridge rectifier from a stick welder, it takes 120vac down to 63vdc with no load. Out put it into a pair of MWT primary coils in parallel. Just like this one. Works but draws too much current. The field strength is around 300 pounds. The coil resistance is about 3 ohms, and draws around 20 amps.

The standard in UK is 230 V not 240 V, like the the rest of the EU. The continent was mainly using 220 V until 1986 and UK 240 V until 1986. The 230 VAC was choosen by the IEC as a compromise between the 220, 230 and 240 system. So actually main voltage in EU should be 230V +/-6% at distribution panel, and equipement should support 230V +/-10%. (voltage drop in the internal house distribution should be less than 4%) But a transition period of 20~25 years was used, during the transition period main voltage at distribution panel in UK should be in the 230 VAC +10%/-6% range, and in the rest of EU it should be in the 230 VAC +6%/-10% range. (Other 240 VAC country like Australia and NZ switch to 230 VAC at least officialy)

If you hesitate at the thought of doing this math for every system you work on, the NEC Article 110.3(B) states: Listed or labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling.

DC burns. It doesn’t cause a muscle lock-up like AC does. It’s more dangerous in that sense, because you don’t feel it beyond the initial shock until your flesh starts to cook from inside out.
