So I am wiring up a H-bridge for a small electric motor for a robotics project and am a little confused. This is the only schematic that I can find for this H-bridge. http://www.robotshop.ca/home/suppliers/rogue-robotics-en/rogue-robotics-dual-h-bridge.html There is a pdf on that site that is...

So I got into an argument with a buddy over the following: I originally inserted a hard drive into my system and it was labeled hda, what i hadn't notice was that it was on the master pin setting now when i switched the pin to the slave setting and rebooted it showed it as hdb are the two...

for a laboratory I had to calibrate a torque sensor that was based upon a strain gage. http://www.omega.com/pptst/TQ103.html Pricey but highly accurate and easy to use You would input a known voltage and read the output voltage. The voltage would change dependent upon the torque...

alas sorry for this wasted post but I just got it working through trial and error

I picked up a good and cheap AC motor that came with its own capacitors <not wired in though> The capacitors are these http://www.weisd.com/store2/NTEMRC370V7R5.html and this is the diagram on the motor http://foxhole.kicks-ass.net/diagram.jpg" Now I tried putting this together but with no...

Not sure if this is the right place for this, but here we go. During the Fischer-Tropsch process to create synthetic oils one of the byproducts is water. Is this water removed from the oil somehow? Also I have been told from some of the engineers that I work with that synthetic oils absorb...

I was hoping that someone here would be able to help me understand variable pitch blade systems for fans/turbines and how they work I have already searched the internet quite a bit without much luck There are a few mechanical drawings but they leave a lot to the imagination Any help is...

I have been reading up using the Line-in on my computers sound card and the pogram XOSCOPE to be able to do some various measurement/analyzing But before I attempt to actually plug anything together i want to make sure I don't wreck my soundcard I have found that some soundcards have the...

didn't the use to offer it for free for students? did they change that policy?

thanks for the listings some of them seem like great resources once again thanks for the advice/information

I am not sure if this is exactly the right place but it works either way. I am interested in learning more about Composite Design Techniques mainly fiber based materials (carbon, kevlar, fiberglass, ect...) does anyone here know of any good resources/books that focus predominantly upon this...

sure your best way to really thwart most port attacks is to just change the ports to somethign really random are you using an active or passive ftp server? i have never run filezilla as a server i rum proftp on an ubuntu box and once i got it set up i haven't honestly had many problems are...

thinkpad i recently (2 months ago) bought an IBM thinkpad and have been incredibly satisfied, the only downfall to thinkpads is that they are more expensive than dells,gateways, ect (no comment on those manufacturers) thinkpads also appear to be one of the most highly supported machines as far...

Hello I am trying to find more information about parabolic leaf spring designs. I have allready learned linear leaf spring design, and I am curious to know how parabolic differs. (besides higher powers) Thanks

For my Design of Machine Elements class this problem is being posed. This is exactly as the problem is stated. The torque on the 400mm -diameter shaft connecting the flywheel with the jaw mechanism should never go above 700kN m. Dimension a copper square tapered key so that the shaft is not...
