AjC Posted January 18, 2007 Share Posted January 18, 2007 Hi guys, Firstly i would just like to say 'Hello', recently found out about Hak.5 and i have to say it's just great :D In general what would be the steps involved to create a usb controlled external device? I understand that a device driver (for window$) would be required, it's more the hardware side i am interested in. Would you need to buy a usb controlling chip, or are they as easy to interface with as serial ports? Many thanks, and sorry for being vague (am working on a top secret project to take over the world ;)), i can provide a more detailed overview of what i am trying to achieve if it would help.

uber_tom Posted January 18, 2007 Share Posted January 18, 2007 I've only used usb to draw power, but i assume the interface would be smiler to serial. probably wrong though. Quote Link to comment Share on other sites More sharing options...
sneaky_rupert Posted January 19, 2007 Share Posted January 19, 2007 You would need to code a microprocessor to handle such a thing.....Some of them come with this capability. Quote Link to comment Share on other sites More sharing options...
AjC Posted January 19, 2007 Author Share Posted January 19, 2007 Thanks for the replies. After digging a little more, it does look as though it will be a complex task. I have however found a book that seems exactly what i was looking for (called USB Complete, if anyone else is interested in this topic), i'll give this a shot and let you guys know how it turned out :) Cheers, AjC Quote Link to comment Share on other sites More sharing options...

Guest ABC Posted January 22, 2007 Share Posted January 22, 2007 if this is any help, my friend, gazza, uses a USB to power a case fan that he uses to cool himslef down[/b] Quote Link to comment Share on other sites More sharing options...
sneaky_rupert Posted January 22, 2007 Share Posted January 22, 2007 if this is any help, my friend, gazza, uses a USB to power a case fan that he uses to cool himslef down[/b] He uses a 5 volt source to run a 12 volt fan? Quote Link to comment Share on other sites More sharing options...
Guest ABC Posted January 22, 2007 Share Posted January 22, 2007 yeah, it works well .. not as fast as it should go Quote Link to comment Share on other sites More sharing options...
sneaky_rupert Posted January 22, 2007 Share Posted January 22, 2007 yeah, it works well .. not as fast as it should go Hmmm...because I know some of those fans, 5 volts is not enough to even drive them to turn. That is interesting. Quote Link to comment Share on other sites More sharing options...
Guest ABC Posted January 22, 2007 Share Posted January 22, 2007 ITS one of em 80 mm though .. look it worked for him, it dosnt really matter to me whether you agree or not. Quote Link to comment Share on other sites More sharing options...
moonlit Posted January 22, 2007 Share Posted January 22, 2007 Alright, calm down chaps, I see no argument here, sneaky_rupert merely said that a lot of fans won't run at that voltage. Merely an observation, no-one said you were BSing neochivers, no need to get so defensive. Quote Link to comment Share on other sites More sharing options...

Merely an observation, no-one said you were BSing neochivers, no need to get so defensive. Exactly, no, like I said, I find it interesting. I learned something new, and defintely wasn't trying to call you out. Quote Link to comment Share on other sites More sharing options...
