A bit of fun here: Language Log � Does God want you to use more initial conjunctions': evidence came from a sample consisting of the first 80 verses of Genesis in the original Hebrew and in the King James translation.The serious point here is the precariousness of prescriptive linguistics. Remember folks, the most you can say is that particular locutions do or don't find acceptability within...

Wish you had a skylight, but don't have the ability to cut a hole in your roof? MAKE subscriber Chris did to, and wrote in to share his solution to the problem: a pv+led-based 'fake' skylight . The concept is pretty simple, but with a nice result. He had some unused capacity on his PV ( photovoltatic ) solar panel, and basically hooked up a bunch of high power LEDs directly to it. To achieve the 'skylight'...

I found a tin of bits and a page of scribbled notes and the above circuit. Got a spare pair of LM3914 and LED as well so could display both fwd and rev not just the SWR. Using the above as a guide I think I could do this also.... build new or salvage a CB SWR bridge (£3 from Rishworth) - as I need a voltage for FORWARD and one for REVERSE. I believe a stockton bridge would be frequency independent,...

(Technology Maverick) Light Emitting Diodes are commonly known as LEDs. They were discovered by a Russian radio technician who noticed that when a charge was passed through the diodes in a radio receiver, they glowed. The MP3 player technology works to compress audio files to such a size that they can be contained in a much smaller physical space than traditional vinyl records or CDs. Users are able...

Well whatever the Pope's intentions, this certainly looked like crowing: "In Rome, Vittorio Messori, who has co-written books with the Pope, said that the Anglican Communion was already losing followers because of female and gay priests." See: 400,000 former Anglicans worldwide seek immediate unity with Rome -Times Online: Of course, what no-one (well, hardly anyone) reports is the steady...

Phasers come with two settings: stun and kill. [Luke] took this seriously when he put two Blu-ray lasers into a toy raygun. He picked up the toy from Amazon for about twenty bucks and set to work. The laser diodes are both pulled out of a 6x BD-R burner, which we think is a pretty expensive [...]

"Obama deserves praise for his compelling vision -- but without more real change, our hopes will be lost. Only by following through with courageous, transformative action for peace can Obama fulfil his promise -- and history judge that this prize is deserved.Let's define this moment as a challenge to be bold -- let’s send Obama a million messages of encouragement and urgency, pressing him...

It’s amazing what you find on t’web. Check this out. That there is a Marx generator . I thought it was a Cockcroft-Walton voltage generator like the one my University department had in their foyer, but bigger. eg: But 'tis not, is apparently a Marx generator, a cousin to that device, which replaces the diodes with spark-gap switches. Basically another interwar electrostatic nightmare. The...
