Thanks Warren and imabug. Guess I'll go for a USB rather than a serial then.

hi, I want to power a digital pen using a USB connected to the PC. What is the exact procedure for this...as in do i require any external circuitry? I also heard about this DTR pin which when permenantly enabled, acts as a power supply. can anyone enlighten me about these things? thanks.

i wanted suggestions of guys who had already read related books. i know i could search for any book on amazon

my friend sandeep here, gives another answer which is similar to the answer already given. the sentence is: "im a perennial liar". kind of a paradox.

we originated because of earth. i consider humans to be parasites. "living" doesn't quite suit us. Earth the the smallest self sufficient being in the universe we know. movement can be through the roots that penetrate the ground or the branches that spread out. it doesn't have to be...

first of all I am amazed a high school student has taken up a project on simulation of atoms. that's shows you are an inspired guy. but simulation of atoms is much beyond just simulation of the gravitational-electrostatic force equilibrium right? you'll have to take the characteristics of...

i guess the smallest, simplest thing that IS alive is our earth. if you think beyond the boundaries, Earth is a microcosm in the endless universe. It is the simplest because just 2 things on Earth are sufficient to aid life, water and oxygen. Probably presence of human emotion complicates the issue!

the very essence of hindu philosophy, if anyone here knows, is that the whole world is an illusion. Attainment of "Moksha" is considered as eternal bliss and as a disentanglement from the birth and death cycle. so as someone quoted...we are an experience machine in ourselves, living in an...

thanks claude, i guess pervect was also trying to convey your idea. my actual doubt still remains... is it possible to place a detector between the two inclined LEDs (remember the LEDs direct light to a single point on paper) and detect the reflected light to a large extent? good day.

first of all, it is impossible for charge to reside in the centre of a sphere. moreover, you have neglected the trillions of charges present in the sphere posessing free energy, which can affect your highly idealised case. it is also not possible to "pick and place" an abstract thing like charge...

thanks a lot for your reply. it was heartening to note that there are no interference effects... though I am not entirely convinced about this. if the LEDs are of the same make, let out light in the same wavelength range, isn't the spectral equation governed by: reflected ray property =...

imagine that i have a pair of LEDs throwing light on the same point on a piece of paper. This is possible if the LEDs are inclined equally at an angle to the normal coming out of paper, right? now if i consider two rays hitting the paper at the same point, then where can i explain the...

a nand gate is just an and gate and a not gate combined. so internally u'll still have the 'and'. Besides u needn't use 2 nands for this. u can use the nand and a not gate. now if u meant using the 2nd nand as a not then u were right. still, i feel one cannot substitute an AND gate with any...

can anyone suggest a good user-friendly book for DSP and applied areas like IP. I would prefer one with a good uncomplicated theoretical coverage. my Signals and Systems background can't be boasted of...but i think i can manage DSP.
