Every sunny sunday the ic powered gardening implements come out Whuuuuurrrrrmmm, whuuuurrrrmmm, bzzzzzzz, bzzzzzzzzzzzzz, ruining what should be a restful day, if it were legal i would shoot them all well maybe in the butt.

Some years ago i read of an attempt to make major engine componets from ceramics, i see now that ceramic coating is available for some parts (piston), so what is preventing the use of ceramics for say an engine block or cylinder head?

Why would a velocity stack improve an ic engines performance?

There is a fair amount of empirical evidence in my world that people experience their Air-Fuel ratio going lean as they go down the race track (drag race). There are all kinds of theories that abound, but none of them make any sense (at least not to me). Most of theories have to do with the...

How useful is discrete math to an electrical engineer; particularly how useful is it to an ic designer?

I am building an autoranging digital voltmeter as the subject line suggests and am having a problem with the ICL7107 chip that I am using. Looking at figure 15 on: http://www.intersil.com/data/fn/fn3082.pdf specifically RefHI and RefLO, with a 2V max input difference between the pos and neg...

I was thinking that it would be interesting if the government put a ban or something on IC bulbs for domestic residential uses. It seems like CF bulbs are more efficient and in the end actually more economical (based on $/hours usable before failing). It seems like it would be an easy...

I am a car enthusiast and have absolutely no engineering educational/knoweldge, so keep that in mind. :smile: If an internal combustion engine revolutions per minute increase simply by opening the throttle, I assume that this is a function of the pressure differential between the air outside...

Generally, what do IC Companies like Intel and IBM hire physicists for? Are they just looking to fill research positions or do we see them on the practical side?

Hi:rolleyes: , How are you? I am agine, I want to know something about IC, Do you have website about all IC design, If you have please help me Cuz I have project about it. I need your help about it. ok if you Could please give me anything can help Thanks,:!) I appreciate it:biggrin:

This may be the wrong forum, so mods please move if necessary (and forgive my error :) ). I was trying to research combustion temperatures (for a typical four stroke engine) as they relate to air/fuel ratio (AFR). I have googled my butt off, and I read many interesting things. But, I still...

What does the ic suffix mean in compound names? For instance ferric, plumbic, cupric? I'm guessing it has something to do with the charge on the metal ion? I have some nomenclature rules from my teacher but this isn't covered. Thanks.

I have formula for 1D wave equation: (*) u(x, t) = 1/2 [ f(x + ct) + f(x - ct) ] + 1 / (2c) Integral( g(s), wrt s, from x-ct to x+ct ) I am trying to find u(1/2, 3/2) when L = 1, c = 1, f(x) = 0, g(x) = x(1 - x). However, for (*) to work, the initial position f(x) and initial velocity...

Hello everyone, I just noticed, my IC for numbers greater then 9 to output 1, has 4 variables, why does it have to have 4 variables? couldn't I just use ABC?, because isn't 0000 == 000 and 1001 == 101, isn't 1001 9 and 101 9 also? what's the difference? I think if i just used 3 variables...

What does this -ate suffix with compounds mean? Can anybody tell about other suffixes like -ous -ic etc as well. Thanks...

Is there such a thing as a morse code ic timer chip or is the only way cascading 555's or something complicated like that. Eproms and machine code is ok if that's what it takes if its cheap and easy for my pc. Only need maybe 3/4 pulses timed. EDIT: want to modify my intercom into a system...

Is there an IC that ouput the input voltage in BCD? I want to make a voltmeter that can display the voltage in decimal number.
