dim bulbs

Cable TV coax in Truckee:

It actually still worked a little bit.

No sign of any SMPS, but the blurb says there is surge protection so maybe a varistor and some diodes in the base.

Looks nothing like the filamant lamps to me.

The ones I've seen are definitely filaments, but those LED ones are very interesting. I wonder how much the reliability is affected by having so many LEDs in series?

Does the coffee come out at the bottom?

Its all fine with me as long as it has no touch screen.

My old Nokia is still the best, tells the time too when you press the right button. In Dutch.

Oh, and it fits in my pocket, unlike that coffee machine.

But you made me realy curious about what you car looks like, I once had a Peugot 404 station that you could start with a similar 'handle'?

Cool, now I will patent the ring power cellphone charger! Would they not get suspicious if you did a ring to your own phone automatically every few seconds?

But really, my phone is IP over cable (together with TV and radio), and I pay for the cable modem electricity myself..

Home Despot carries these, with wattages of 40, 60, 75?, and 100.

Sold for use in lanterns and the like.

Ya, that period was supposed to be a comma.

No, Italian go to an espresso stand for that.

I still use a Nokia 2115i. Works, does the job. It tells military time but only on its display. When you can see it which is difficult in sunlight.

My car is a Mitsubishi Montero Sport. That one can't be started by crank anymore but but my 1st car (16HP Citroen 2CV) could. In fact it had to be because as a student I could not afford a new 6V battery. Only VW Beetle drivers (the folks that got government subsidies) could. So I rode around sans battery for a long time.

The squirrels probably wanted to turn it into a Goubou line or try a TDR scheme.

Somebody should invent bad-tasting PVC.

Today we can all afford them, partly because the cheap ones are designed & made differently. (The first 2 I mean.)

We now have overhead cams, and the next generation electric valves. We have exhaust gas recirculation, fuel injection, electronic management, lean mix tures, multigrade oils, huge service intervals, reliability, properly regul ated charging, diesel engines, etc etc etc. The turbo dates back to the 170

Other aspects of cars have come further since 1915. Cars then were generall y a nightmare to drive, and real death traps.

You may be right that its 1&4 rather than 4&1 - its not 0.25.

I've seen those in hanging lamps with the real lighting being ceiling-mounted LEDs.

Amazon shows them selling at 40W and 60W for a dim glow. That does seem horribly inefficient. A tungsten filament running so cool could be in a high vacuum with IR reflecting glass. Vapor pressure is just 1 Pa at

Here's a frosted halogen lamp rated at 230V 18W. Connected to 110V.

Sure, it's not very bright (there's a neon lamp in the transformer box mains switch for comparison), but at least it is visibly lit.

Visible light out is about proportional to V^3.4.

Yes, I meant GLS lamps. Halogens run hotter so do better

NT

Those equations only hold at near rated voltage. I wish they predicted further out but they don't.
