ok, help with a.... differnet sort of problem
ok, i may be known here for asked weird questions about random projects, like when i built my computer for the first time, or wanted to put LED lights on my surround sound..... see i told you...
well, this time i'm wanting to control a RC car with my keyboard on my computer
i had a few ideas on how to do this
but before i go into detail about how to do this, FIRST i ask the most important question
how can i control the power used on a usb port?
my idea was, to take a usb cord, solder then ends to 1 button, and then have a button on the keyboard, turn the power on, and off, for going, and not going
i know this would take alot of usbs to control forward back, left and right, and 3 other options that are on the controler... total of 7, but i'm only wanting to do 4
so, is this possible? can i control how much power is sent, or at least something to complete the circut to make a "button press"?
i was going to connect a laptop to the RC and then control i with another pc via remote desktop (works good with keyboard, no delay, and also for a webcam attached to mounted laptop on RC)
there are a few more options, but i'll stick with this one for now..
can i control the power sent to a usb port? or is there something else that can do what i'm asking?
ok, scratch out most of what i said above... i found a better way of explaining it, how can i use my usb ports as a switch, without sending 8 volts of electricity into my computer resulting in a very unhappy person
ok, here's what i want
RC -*soldered to* - usb cord -*connected to* - computer
and then use the computer keyboard, to turn the switch on and off for each port...
possible? if so how? if not, why not?
