Nope, but it will drive a car, just not as fast as I'm sure he would like. When he realizes his error, he'll be able to reason much better about electrical and mechanical engineering than many of his peers in school (if he decides to go to

Do I count as 'active' if I only use the photo backup from my Android phone?

Ah ha! That's actually kind of cool. Power's given as: P = V^2 * R R is given as: R = rho L/(pi r^2) Substituting: and clumping constants: P = (V^2 / r^2) * (rho*L/pi) Weight is proportional to r^2, we can see that voltage and weight are i

Yes you are correct, the power used to switch a transistor is P = a * V 2 * C * f. The static power dissipation from leakage currents though is Ileak = Isat * (e (qV/kT)-1). http://www.siliconintelligence.com/people/binu/perception/no...

What do you mean by doubling the AC voltage to decrease the weight by 25%? If I continue doubling, will I eventually not need a conductor? The true power of AC is the fact that the energy is transmitted through the electric and magnetic fie

AC becomes less efficient (financially and electrically) at more than 1 Megavolt. The big big transmission lines in the United States actually use DC because the AC transformers would have to be so large, and the losses at that high of a vo

Absolutely they could with my frame of thought. I like to think the best way to view the world is a world without humans. This, to me, is an easier way of thinking than attempting to place myself in the views of the thing I want to think ab

One day about a year ago, I woke up and had a single thought pouring through my mind - "It's better to assume everything has a consciousness until you can prove it doesn't". At this point in human history, we are standing at the top of a py

The cells are essentially identical. This is a fundamental question when doing rat studies, you would like the regions of the brain your are affecting in the rat to be similar to the regions you would find in a human brain. http://learn.ge

Meditation can be many things, it's really up to the person what they do while they meditate. The best explanation I have is ignoring your thoughts. You aren't sleeping, your mind is blank. Meditation feels like (to me at least) the feeling

The right arrow on the 'going out' or 'stocking up' page first adds more rows, then if you press it again it shows all new rows. Consistency would make it better.

Just thought you might like to know that there is another project with the same name. ( http://ccv.nuigroup.com/ ). Although they seem to stylize it with all caps. Cool though, looks good.

You're correct! If you look closely, you can see a couple bubbles near the top of the right one.

It sounds like you were using liquid cooling, did you ever try phase change cooling? Something like this ( http://www.youtube.com/watch?v=Z_X_hgtlJpA&t=36 )? I saw a demo of it a couple years ago, really cool stuff.

Looks cool. Minor comment though, when I saw the cell phones, the first thing I thought of was button candy. http://2.bp.blogspot.com/_ooCR1rvj6h4/TSFPFXg1CFI/AAAAAAAAB_...

I did my senior design project on an infrared related area. Things look really weird in the infrared. http://imgur.com/SLGvT,y79tC First image - can you guess which one is diet coke, and which one is water? Second image - I was shining a

Compared to the temperature changes that the wafers go through when processing (>800C for annealing, lower temperatures when we start putting more materials on the silicon's surface), the silicon itself will likely be fine from the temp

What is the performance difference between 32 bit and 64 bit for memcached? I know redis has a lot of overhead with the 64 bit version [1], does memcached suffer the same fate? [1] http://serverfault.com/questions/221695/deploying-memcach

Absolutely. You'll likely need to use a thermocouple though. Something like this http://www.adafruit.com/products/270 and this http://www.adafruit.com/products/269 play nicely together. Hook the sensor up to the Arduino, have it print o

This is the kind of stuff python is really good at doing. I can't really vibe with Perl, but this Python script should work well, another one with graphing coming soon. Plain reader/logger: https://gist.github.com/2980913 EDIT: I don't ha

This is cool. I know this isn't how they actually do it, but seeing it in a language I can understand (Python) and not in C is really pleasing. You can do tons of examples, but until you figure out how the machine works inside, you'll be co

Ah sweet, now I can pay to have someone else to show the people I care for how much I care for them. There's really nothing that beats a crappy looking home made card with an actual message in it. It takes less time, money, and has more imp
