Looking good!!! Well done so far!
Are you going to leave the power invertor wired to the battery like that, or are you going to make a system to switch power to the invertor on and off? Even when turned off the PC will draw about 7W of power, which dosent sound like much, but it means the invertor will be running, which wont be that efficiant with such a low current flowing through it. I recon that it would flatten the battery if left on for a few days.
Im intending to make a system which hibernates the PC and then will turn of the invertor when the doors are locked. Just an idea.
Quick update on my system;
Went to the scrap yard on Fri and got a spare glovebox so I can hack it up! Ive done a bit of trawling of the internett over the W/E and come accross this website:
www.aria.co.uk/
Ive now got my shopping list sorted out which I hope to purchase thisafternoon. It comes to £176 and includes every thing Ill need for the PC, except a few fans and mabey some cables ect. It will have an 2.4GHz AMD dual core prosessor and 2G of RAM. Not too bad for a car PC for that price. The motherboard is micro-ATX so should fit in the glovebox with minor alteration. The hard drive is a bit small, but I can always add on more later on, and im going to run the OS (probably Linux) off a seperate IDE harddrive which Ive already got. Anyway, the list;
ECS AMD690GM-M2 AMD 690G/SB600 AM2 Motherboard £ 28.55
AMD Athlon 64 X2 Dual Core 4600+ 2.40GHz (AM2) £ 54.95
SV 500w SilentLoad 20 & 24+SATA PSU £ 9.95
80GB Seagate Barracuda SATA2 8MB £ 22.75
2x 1GB Arianet PC5300 DDR2 667 SDRAM £16.95
So there we are! Hopefuly itll arive for next W/E!
As I mentioned before I think Ill use Linux as an OS as the system should run a lot better and smoother than with windows. Also I can modify the code to make a application specialy to controll the features I want.
Sorry for a long post and good luck with your projects guys!!!
