Re:So how much?
The links for International Rectifier, for those *#$% off with Congress and wanting to build their own damn Rover:
- Rad Hardened Single chip MOSFETs
- Rad Hardened Multi Chip MOSFETs
- Space-Rated DC-DC Converters
- Space-Rated Low RF Power DC-DC Converters
- Rad-Hardened Voltage Regulators (fixed)
- Rad-Hardened Voltage Regulators (variable>
- Rad-Hardened Gate Drivers
Some of their other military/avionics stuff may be space-rated or rad-hardened but it doesn't say so.

Re:Well, it's kind of natural given the new economI certainly understand your grief, Hermit.
It seems all the sciences/engineering/tech fields got hit. Anything where lots of effort went into training.
I can understand the businessmen and their concerns about getting cheaper skilled labor. Its the same concern I have when I can get cheaper stuff.
My main concern is with Congress, and how they've been passing all this one-sided law.
Outsourcing labor, Fine! But what happens if I try to buy a CD which is cheaper in China than here? Can't do that! Its a Violation of some businesses' marketing model. Well whoop-de-do, we have a "marketing model" too! We paid in both time and dollars for our education, and we are paying a hefty income tax if we are making enough to keep a roof over our heads... and that "business model" needs protection too.
Of course, business can get labor somewhere else cheaper. Those people do not have to pay US property or income tax, or have the cost of living overhead we have here. I can get my music cheaper too if I don't have to pay all the RIAA overhead, but somehow skitting around paying the RIAA is considered illegal, but outsourcing skills is simply business. RIAA cannot compete with damned near free. Neither can I. We protect RIAA with DMCA. Either provide me housing, food, and creature comforts at foreign rates and relieve me from taxation - or protect me too, or my kind will cease to exist.
Personally, I am perplexed, as I have a lot of skills in refrigeration design, and its quite obvious to me how to design HVAC systems that take advantage of ice baths to store enthalpy so not only can I time-shift the energies required to transfer enthalpy (BTU's of heat energy) to times of abundant power in the middle of the night, I also take advantage of radiating the unwanted heat to deep-space much more efficiently than when I have a 6,000 degree kelvin heat source overhead during the day.
Not only that, I have a whole bag of evaporative cooler and other tricks in my bag to make SEER soar. There are a whole mess of tricks like using gravitic pressure assist to keep refrigerant from flashing before it hits the thermal expansion valve, or using pipe-in-pipe methods to recycle heat flows. These have to be custom-designed for the application for maximal efficiency.
There is a whole mess of new technology here to be explored. Brand new scroll and screw compressor designs coupled with SEMA motors and International Rectifier drivers, driven with custom programmed AVR micropower controllers. Yes, like Linux, it will take some time to set up, but once its running, and people understand how it works, it will work as long as you want it to. Efficiently. And if something better comes up - if you know how the thing works, its easy enough to integrate it in.
But what happens? The powers that be want an off the shelf box, just like in your field, they want a windows box. Anything so they don't have to understand what they have. Just use it.
We cannot thrive on ignorance!
From what I see, we are rapidly approaching "peak oil" and energy prices will soar. Trying to tell the executives about this is just as hard as selling them on a Linux system. They will pay whatever it takes to have the mainstream unit, no matter how virus prone or inefficient it is. A big company offers them the comfort of being held blameless for going that way, no matter what goes wrong. Its the little guys who stand to profit/lose personally which seem far more likely to adopt innovation than the corporate leviathans.
It seems a shame when I see so many technical people underemployed when I feel our country needs us more than ever. At least the kids can see us and avoid our mistake like the plague, and get their tra

Re:Fluorescents are much more efficientI agree with you that what you find at big box retailers is limited and substandard quality, but what do you expect from *mart, *depot, *co, etc. The cost of making a dimmable electronic ballast is only slightly more than a non-dimmable electronic ballast. See http://www.irf.com/product-info/lighting/fluormai
n .html There are just so few dimmabel CFLs in the mass market that they fetch a premium. If you really want to just pay 69 cents for a bulb then stick with massive power bills. Similar deal with bulb color/quality.What you are seeing is the inefficient market created by the wallmart effect - lower quality and smaller selection. If you want something worth paying for go find an industrial bulb supplier and invest in something that will really last 10 years and provide high quality light at 100 ln/W. Check out ballasts that accept replaceable compact fluorescent bulbs. You may not always get what you pay for, but you'll never get what you didn't pay for.
One other reason for shortened life on CFLs is that they are electronic and if the manufacturer skimps on surge suppressors they'll die then they get spiked, but every body on
/. already has installed whole house surge suppressors at their breaker box so this is not a problem, right????? -
*ahem* "Ruggedized"
I've been seeing this word quite often in datasheets of chips we use in the lab. (Like here, in the Description.) My first impression was a small, black IC with a confederate flag painted on top... perhaps some unnecessary facial hair, as well.
Now, the word 'rugged' comes from the Scadanavian word for 'shaggy'. However, the popular cowboy mentality has managed to transform 'unkempt' into 'robust', as evidenced by the definition for 'ruggedize':
--to strengthen (as a machine) for better resistance to wear, stress, and abuse--
I'm going to assume, then, that my chip contains a powerful Texan spirit that herds the current like the stampeding mass of electrons that it is. -
Re:Of course...
That's not a transistor. THIS is a transistor.

Re:bios
Every board has a CPU (Actually, every chip is some kind of CPU), even if it is a dedicated CPU
Every chip is a "CPU?" Okay...
- Here's a chip that's a resistor array... Is that a CPU?
- What about this TI uA741 Operational Amplifier?
- Are Optoisolators a kind of CPU?
From Dictionary.com: central processing unit (n. Abbr. CPU ) The part of a computer that interprets and executes instructions. None of the chips I've mentioned interpret or execute instructions.
I think what most people around here want is something akin to the old Amiga Autoconfig system, plus a way to automate driver updates, and the whole shebang be platform independent. -
The article is there now
[On their website,] I saw a lot info about power supplies and converters, but not anything that was a 'new generation computer chip'
On the homepage, it says, "Investor News:
International Rectifier Announces New Generation of Power Chips more...". When you click more, it says, "With energy savings as great as 50 percent, these power chips offer huge potential to...."
