You can pout, cry, and scream, but your whining makes no difference (especially if you aren't even an American). All ordinary Americans will lose, because... Trump will appoint a so- called conservative female. The only thing conservative about her will be fiscal. She certainly will proclaim to be a Christian, but the cannibal left can rest assured she will not be a Christian (not acco...

Today, (Sep 16) global energy giant BP (BP) wrapped up its three-day investor event, in which it "said the relentless growth of oil demand is over, becoming the first supermajor to call the end of an era many thought would last another decade or more." This is a big deal, as this Bloomberg article highlights: BP [...]

California has been shutting down fossil fuel and nuclear power plants for years, making up for the difference by purchasing power from neighboring states. But the current heatwave in the West has dried up (pardon the pun) this Band-Aid solution, and the people are suffering, literally: https://news.trust.org/item/20200906022155-95z56 And, WAIT, there's MORE!

I need a simple circuit design for a slow fade-in AC dimmer. In a dark theater, suddenly turning on the lights is a somewhat unpleasant experience. I want a simple circuit compatible with 110 volt dimmable LED lights that will slowly ramp the light output over a period of about 5 seconds or so. I have found a number of simple designs that would work for 12VDC LEDs, but none for 1

Up here in the country, I see a lot of motor boats parked in driveways. I suspect that most are seldom or never used. I got curious about cost. Seems like a dinky outboard motor costs $1000, and some are $8K or $25K or even $45K. And a serious speed freak will hang three on the stern. I can envision some domestic discord. -- John Larkin Highland Technology, Inc trk ...

JL posted a couple of circuit suggestions in the "slow fade-in circuit" thread that used protected MOSFETs. (*) We've had a few discussions about those gizmos in this very boutique. I've actually never used one, but IIRC the wisdom has been that they're not nearly as robust as their makers claim. It's been awhile, though--anybody have recent experience with them, favourite parts and...
