My current plan is to use like 8 relays to control power to 8 outlets in turn controlled by a d-type flip-flop in turn controled by the parallel port.
I wasn't sure I wanted to pull all the current to operate the relays from the parallel port is the only reason I'm using the flip-flop.
I want to avoid using a microcontroller, principally due to cost, and my knowledge of electronics is rather minor, but I am handy with a soldering iron and know what the parts do generally.
Aside from the hardware aspect, I also was wondering how you can send signals from the parallel port (if its even possible) because as much as I know about hardware, I know much less how to program and was going to have a friend do it for me, and he whas no idea how to directly control output signals accross the parallel ports pins.
Any input is gladly welcome, even if its just an I'm not sure if its possible post.
