    That sounds good but I have not been able to find anything similar for windows users!

    Centrafuse plays the files fine but it doesn't seem to pick up on the song info and doesn't support album art etc so importing a large library of those files really is a woeful experience that really...

    Its a good screen at a good price. Don't expect to read it in the sun but that goes for most in car setups.

    iPhone support - Any update?

    Last I read this was not available but was in the works... Any update on it? I was going to just ignore that and sync the carpc library with my desktop library which is now all in apple format... But...

    I did solve it, surprised I forgot to post on here!

    Turned out that after about 4 hours debugging, the microcontroller was faulty. I must have accidently sent 12v through it at some stage during...

    Not had time to fully test it and identify issues, all the gear (AVR Dragon & Multimeter) is in the car just waiting but I still have bastard exams!

    I just ended up swapping out the zener for a quick and dirty 7805. Doesn't heat up at all and is fine, been running in the car for a couple of weeks now.

    Currently having a problem where it seems...

    Ok, it is now built. Working just great, I would make a couple of revisions for the next one I build (probably do a couple for friends). The only change was swapping the 4.7 Zener which regulated VCC...

    Not going to work, transient voltages and other nasties will ruin the laptop. Added to that it probably requires more than the ~12v your car will probably supply. Pick up a cheap adaptor on eBay and...

    Serial data string printout?

    Is there any way / plugin which will allow me to have a string from serial printed out on the front page of CF? I'm developing a little power controller module specifically for laptops which will...

    Ok I tried it and I was totally wrong, it weirds out completely :) Thanks for bringing that up scsirob, I think my confusion came from other times when I was testing on a logic board but of course...
  12. Actually after reading the spec properly I'm...

    Actually after reading the spec properly I'm pretty convinced the original setup will work, it will see a logic 1 otherwise it will be tri-stated and not used. The same applies for the remote_start...

    It would work if I set the port to 0 however I suspect that setting with pullup and having the jumper to ground whilst keeping the resistors may allow ISP without removing jumpers.
  14. Ok, it is updated now.. hopefully this will be...

    Ok, it is updated now.. hopefully this will be the 'final' version. I added another line for PC Power so now it doesn't matter how the switch is connected, both lines will be drawn to ground and the...

    I just did a little test with the tiny84 and the diode method, works great so I will stick with that for now.

    I was pretty sure it was 10 too O_o. Another thing is that I was fiddling with the idea of using a transistor to signal the pc_on incase I can't pull the signal low enough with a diode. I don't...

    Thanks for the points, all definately something to think about. I'm not quite clear on your meaning of putting a diode between car_remote and +5.. I can't quite see how that works?

    I will add a...

    Mildly updated version, relay coil and transistor are now on a protected 12v supply

    Here is the latest version using a tiny84. It doesn't have a full USART so I'm not going to use it for that.

    Power on/off will be controlled by the remote from the car head unit, it will only...

    So I could literally just do this and bring the IO to ground when I want to start the system up?
  21. I think I might be getting slightly confused...

    I think I might be getting slightly confused about using the transistor to short the wires, would this work correctly or am I on totally the wrong path:?

    Ok, how does this look:

    I decided I didn't want to rely on the internal pulldown so added one. The cascaded relay is no longer...

    The high side driver is pretty impressive, I think for now though I'm going to stick with using transistors and relays, I have not really used transistors before so now is a goot time to learn and...

    Actually I forgot to add them for the relays!

    What I meant on my previous post was possible transients coming from the actual car power source which the transistor will be connected to?

    Thanks for the input Rob, some great suggestions which I'm going to use so standby for a redesigned version using transistors. Although won't there be the risk of a massive transient going through...
