CarPC 11/18/09

Sorry, I fell asleep before I could post last night. I have completed the power circuit for the system. At first when i turned on the system it would send the power from the caps into the computers 12v line and would instantly be drained. To get around that problem i simply soldered a led on the pc power line to prevent power from going back into the pcs 12v line.

Not much time to work on the project today, all I managed to accomplish was soldering the starter circuit and start on the pcs power circuit. it still needs work because it doesnt stay on long enough for the computer to pick up the slack. I didnt want to waste too much time messing with the remote so i set the lock button to turn on the system, the unlock button will still unlock the doors unless i find a new use for that button.

For some reason (need to look into) one of the circuits switches the relay on when it is supposed to, but it will not switch off until the power is disconnected from the circuit. There seem to be no other problems caused by this so i am going to use this circuit for the VATS bypass. If I ever need to switch off this circuit all i need to do is activate the safety which cuts the power to all circuits, including this one. I soldered the VATS bypass and ACC circuits so those are ready to install. I was going to solder the starter circuit but im out of relays and the stores are already closed.

Project: Car PC “so far”

I was hoping to blog this project from day 1 but i didnt get to it until now. I am using parashell to control the car pcs parallel port that the car will be wired to. I checked out the parallel port and unfortuately when it starts up it switches the pins high and low a few times. Fortately one of the pins stays on after they are done flashing so i am going to use it as a safety. while this pin is high it will switch a relay causing the other pins to not have a connection, preventing problems such as the car starting and stopping repeatedly while booting.

I have bought a remote entry system that im going to use for locking and unlocking my car. Since my car doesnt have a electric trunk opener i am going to use the trunk button on the remotes as the power button on the car pc. It is going to be controlled via bluetooth and wifi. That is a work in progress.

Current project: Car PC

Scenario: its the middle of winter and 5 degrees below zero, the car has been sitting outside of the gate you work at, getting cold, collecting frost and ice on the windows. You could just pay to have an astrostart installed but wait… you can make one thats better!

Project: install a car PC giving you remote control over devices such as defrosters, ignition, radio, etc.
