I would like to ask for some help regarding the circuit design of this motor...

Currently I am using a pc to drive a stepper motor through a xylotex-brand motor controller. The problem is the PC's time clock just doesn't allow for steady movement. What I need is a specific controller to handle the signal to the motor. All I want the PC to do is send a command to the...

How would one use a while loop in the C programmin language to ask the user if they want to terminate the program, or execute it again. You could say press 1 to terminate and press 2 to execute again. How would someone set that up with a while loop?

Our government is supposed to be a representative body - that is, we citizens are not given the right to participate in a true democracy, but we are allowed to elect representatives who we expect to vote on our behalf. This system has been broken for a very long time. It seems like no matter...

Had a bit of a dispute with a friend over the possibility of a circuit and what it could do... I could be wrong, but I don't see how this is possible - He claims that it's possible to wire a circuit containing three switches and a light, and have it so that any of the three switches can turn...

Has anyone here happened to design a remote control... I am just into it...so i am looking for information to understand how can we go about doing it..

I have a few Control System questions: I'm looking for a simple explanation of when each of these are used... whenever I read about them, I just can't remember which is used for what; this is probably because the book I'm using explains it in hard to understand terms. 1) When do you use a...

Just like in the title, I'm looking for some software to make sounds in music much louder. I have a few nice sounds, but they're too low, even when I manipulate the volume in speakers it gets tiny louder but still low, is there any software that let's me do such thing? Thanks

I am having a problem with plotting Bode plots in Matlab. We are required to plot a e^(-sT) (simple time shift) as a Bode plot. The "bode" function in Matlab requires either a TF, ZPK, SS, or FRD system as its first input. I cannot seem to find out how to plot the exponential. I can easily plot...

I'm having a problem setting up a certain differential equation which I need to solve a problem. Here's the problem: I'm given a feedback control for a certain metabolic pathway. I've attached a picture of the network below. Now what I can't figure out is how to write the differential...

I'm building a spacecraft attitude control simulation and I'm looking for some references to help me build a realistic mathematical model. Could someone please help me? I'm testing an AI library I built and that is requiring a lot of research in itself. Thanks for your time! Jeff

Well there isn't a topic on Linux tutorials, that I could find, so here's one - Linux Advanced Routing & Traffic Control HOWTO http://www.tldp.org/HOWTO/Adv-Routing-HOWTO/index.html Hope some find it useful. Please add others.

Hello there, I just got a question in control systems that i need help on... Hopefully, somebody genius on this forum can help me out.. If F(s) = 1 / (5s + 1) 1) Determine the DC gains of the open loop system and the closed loop system 2) Determine the time constant of the open loop...

Differential equations! :smile: Hey, We're working on a mathematic project, which is about rotational control of a satellite. It's in some ways connected to physics,because we're supposed to analyse the dynamics of a satellite. First a one-axis, then a three axis model. Anyway, most of...

I have been reading about the research being poured into the development of a male birth control pill. The articles I read were dated in late 2004 and mid 2005. I was wondering if anyone has any more recent news about this product (when it's scheduled to come to market, etc...)? -Zach

Hi all! I started my first control engineering course this semester. There are some terms that confused me. I am now learning closed-loop systems. And the lecturer was discussing the reduced sensiticity to process disturbance and load variation of a closed-loop system when compared to a...

Hello, I am making a lab investigating friction of an object and I just need a "method" of controlling acceleration in the experiment so the object travels at a constant velocity. This is really the only way I can think of having the experiment work out correctly so I really need help with this...

I would be very happy if there is anyone that knows a way to control the inkjet cartige with pulse signals instead of the computer. I want to be able to "shoot" ink droplets from all the nozzles at the same time. I need to know how to operate each of the pizo crystals, and then to operate them...

I am trying to figure out the best way to build an IR remote control. I was going to use momentary switches on the remote and need 18 switches. The remote is going to eventually control a preamplifier I am building for a senior design project which is still a few semsters away. I figure it is...

Does anyone know of a circuit that will digitally control a voltage multiplier circuit. i believed it to be a DAC but this is incorrect. Does anyone have any ideas?

I'm looking for some terminology. Numerical methods of analysis seem to use different terminology for the same things, such as an "element" or "finite element" used for stress analysis, versus a "control volume" in thermodynamics. I've also seen both terms used in CFD. Is there a proper term...

I read a couple of years ago, where the "space weather", was going to be controlled for the protection of satellites. At the time, I was appalled at the audacity of that kind of move, when "Space Weather", is so poorly understood. Today I was reading about gamma rays created by the Earth linked...
