I want to build a circut that leaves the fans on on an xbox 360 for like 5 minutes after the console is turned off. So this is a block diagram I made in paint (so excuse the sloppiness)
**broken link removed**
The 5v is a standby voltage the remains even if the xbox is power down, as long as the xbox is plugged in. The 3.3v is only on when the xbox is powered. The 555 is set up in a monostable setupDo I need all the resistors, they are only there as current limiting resistors. I chose the nessacary current following the 10:1 saturation rule. I drew the transistor with bottom as base left as collector and right as the emitter. I am not to familiar with transisors or how to use them properly so could someone tell me if the transistors are set up properly.
