Is een 386 voldoende (8 mb ram) om mp3z vlot te draaien.
Heeft iemand ervaring met home-made car mp3 systems?
En wat is een goed programma onder DOS om mp3z te draaien, die je kan besturen met zo'n keypad ( http://users.nac.net/thesite/carmp3d.jpg , enig idee waar ik zo'n ding koop? ;))
Alle hulp is welkom...
mischien iemand enig idee wat voor voeding je voor zoiets moet nemen, en of je uit je wagen ergens 220 kan halen? ;)

Nyaano !

Ik denk dat een lennox met een carkit goedkoper is als wat jij wil.
Wat denk je wel niet wat alleen al een 12v -> 220v converter kost? Daar betaal je ook bijna 600 voor. Plus de pc + software....

I just hate it when the computer does what I tell it to do and not what I mean for it to do.

Ik heb een site met 2 links... 1 is een DOS-player... ideaal geweest=broken link. En 1 is een winampplugin voor keypads zoals jij hebt. http://www.mp3car.com/software.html en dan kun je dit dus doen:

First and most important is to get your hands on an extra computer which meets the minimal requirements for playing a mp3 audio file under Windows. I currently run a Pentium 90 and have no problem with skipping, delays, or booting. However, nothing smaller has been tested that I know of but I remember an old 486/33 laptop that would never play mp3s for me! The other issue that needs to be addressed is how you are going to pipe the audio signal through your speakers. I currently have an Aiwa head unit that has auxiliary input on the front that allows for easy inputs but there are several other ways which this can be done. If you have an amp, you can just input the signal directly, otherwise I would suggest using a FM transmitter that will transmit the audio signal over a radio frequency that you can set your tuner to receive. The radio method does cause a loss of quality, however it does still sound fairly decent. You also will need to obtain the following equipment from a local geek store. First, you need to get an inverter. An inverter allows you to run an AC device such as a computer off of your cigarette lighter. Any brand should be fine, sign wave inverters are the best and I would not recommend square wave inverters. You will also need a power cord that will go from your inverter to the location of your computer. The trunk of the car is the most popular mounting location so you will probably need an extension cord was well, try to get a color that matches your interior and make sure it is a good quality heavy duty one. My friend has great stories of his car sparking after he cut some electrical cable in his car door. He paint still has the burn marks to prove it. Way to go FiberOptic!! You also need an audio cable that reaches from your computer to the input of your sound system. Since I use the head unit for input and the computer in the trunk I needed an audio cable which extends the length of my car. You will also need a keyboard cable which runs from your keypad control unit to the computer. Again since I have the keypad in the front and the computer in the back I needed a cable that runs the length of my car.





Configuring the box

Take the PC and get it up and running in your house. Make sure you have proper cooling, multiple case fans are great for those 100+ degree-days when you are pumping out the music. Install the newest version of windows and WinAmp (please register you copy, support cool software!). Go into the bios and set the halt on errors to whichever option doesn't halt on errors, most likely "No Halt On Error". This will allow your box to have problems that are not critical to be bypassed if something bad happens. This is not critical but can be much easier then blind troubleshooting, because most setups do not have displays in the car!

Next, take all your CDs and convert them over to MP3's. If you need help with this please go to http://www.mp3.com/ and read their informative documentation, also grab a few of their new artists who are supporting the Mp3 format. Copy these new mp3s into a directory on the new system, the most efficient way to do this is over a 10base-t network. But, any system will work including the old master/slave hard drive swap tricks. After this is complete you need to disable the windows scandisk. If you are running OSR1 of windows you are fine (this version did not include scandisk on power failure) otherwise you need to use a program called Tweak UI to disable this feature. The program is available from

www.shareware.com. Add a WinAmp to the startup folder so that it launches upon boot. Make sure not other programs taking focus over WinAmp or you will not have control of the correct window from you keypad. Enter WinAmp and add all the mp3s you have to the play list editor. Save this list, and without closing the list exit WinAmp. Shutdown the computer, remove your keyboard and mouse and now insert your keypad. Restart the computer and WinAmp should load with the full mp3 play list activated. Using your keypad enter "+ 1 +" to jump to the first track of the play list. If all is working properly you should now see and hear WinAmp playing. Test the tracking of the mp3 by pressing 4 and 6 on the keypad, the mp3 should load and play with ease. Also try jumping to a specific track by press "+ track +". Now, on the keypad press "*", this will stop play of the mp3 and then turn off the power to your computer. This will simulate the loss of power in your car. Turn the machine back on and make sure that the scandisk option of windows is disabled. If you load back into windows with WinAmp running you are fine. Otherwise, read above how to disable scandisk. For the final test remove the monitor from your computer and power up. Everything should work as normal you should still be able to use the keypad and cycle through your play list without a problem. Your box is ready to be installed. Good Job!



Installation

Now that your box is ready to roll its time to complete the installation. First you need to decide where you are going to mount your computer. Most installations take place in the trunk of the car. Place the computer in the proper place and bring all needed cables and devices out to your car. Install the inverter into your cigarette lighter and plug the power cord into the inverter. Next locate the path from your computer to your inverter. Since all my cables run near the head unit in my car I ran all cables from the trunk to the front middle dash. Most cars have a tunnel or removable plastic cap that you can remove to feed wires from the rear speakers (or trunk) into the cabin of the car. My cap was located behind the side of driver side rear seat. Pulling in to the side revealed a path that I was able to feed wires from the back into the cabin with ease. I then removed the floor door panel on the driver's side in the rear to feed the wires underneath. This was held into place by two screws and was easy to remove and reinstall. The wires then travel underneath the driver's seat up to the middle of the dash where they are feed under Rubber Queen change holder thing to the inverter and head unit. Repeat this for the keyboard cable. Most people will be patching the audio cable into there amps so they will not need to run a audio cable the length of there car but if you are using the auxiliary input method run a audio cable to the head unit as well. Connect the power cable that is plugged into the inverter into the extension cord from the back. Plug the keypad into the keyboard extension cable that is now near the front seats. Connect the audio input to your head unit or directly to your amps. Turn the switch on the computer on and make sure everything is tightly secured. Start your car. Now switch on the inverter and go to the trunk and make sure the computer is booting. Select the input on your head unit and grab the keypad. You know your computer is ready to accept input when the windows start sound is heard. This is a great feeling! Press "+ 1 +" on the keypad and you should have magic music coming out of your computer into your car stereo system! Congratulations!



If you are having problems please check the FAQ or email me at moon@home.com. Thanks to Jerry Palmerino for completing my installation. It looks and operates great!

Ah the best part. We could really call this the testing phase but that makes it sound way too much like work! Once everything is setup and seems to be working we are ready to test the stability of the system. This involves getting a few people, loading them into your car and then cranking out the tunes while you drive around town showing off you music power! Make sure you have a mp3 for every situation! Have the cops theme and some road rage music. You never know..

Ik heb eens bij iemand gezien dat hij een mininotebook in z'n auto had voor mp3's.
Hij had een dockstation in z'n dashboard ingebouwd, werkte perfect en zag er wel gaaf uit.
als je het geld er voor hebt is dit zeker een aanrader.

Het belangrijkste is eigenlijk een programmatje vinden dat mp3z in dos draait...
heb dat gehad, maar waar ik het gehaald heb is me onduidelijk :(
en dan de stroomtoevoer... hoe moet ik dat flikken?

Voor afspelen voor een mp3 heb je volgens mij minimaal een pentium nodig.

Oud is vaak al nieuw genoeg

Beetje vaag, maar toch: een paar ComputerTotaal!s terug hadden ze een item over het gebruiken van een oude 486 als Mp3-jukebox.
Als ik het ff voor je moet scannen zeg je het maar... (moet je wel ff een meeladres in je profile droppen)

kijk eens op http://www.mp3car.com staat zeer veel info heb er zelf ook veel info vandaan gehaald moet alleen nog een converter bestellen en dan kan ik de mijne inbouwen
ps werkt perfect met irman afstandbediening

En waar haal je die afstandbediening?
en moet een 230 watt voeding gevoed worden met zoveel, of is minder ook goed?...

Verwijderd

Een pentium 60 of 486dx4-100 is het minimum voor 128kbit mp3's.

Een 386 of kleine 486 is NIET geschikt om mp3's te decoden, wel om een PUMP aan te sturen (is een externe MP3 decoder voor op je lpt1).

Om 220v te krijgen heb je een converter nodig, die kost +/- 200 pieken. Als je handig bent met elektro kan het voor minder dan de helft.

Verder zou ik voor linux gaan ipv DOS. o.a. omdat je dan LFN ondersteuning hebt.

oke om maar eens even dit topic omhoog te schoppen, daar ik eersdaags zelf een mp3 player ga maken voor in de auto, van een oude 233 Mhz die ik op 90 ofzo zet zodat tie zonder koeling kan.

Hoe zit het met de stroom.
hoesnel is je accu leeg?
en ik hoor veel mensen zeggen dat je alleen 12 volt nodig hebt, kan je dan niet de 12 volt uitgang van je voeding doorknippen en deze direct op je accu zetten eventueel met een relais via je remote contact (zodat er niet altijd stroom op staat)

Open liever een nieuw topic dan zoiets enorm ouds uit de diepste kelders omhoog te slepen ;) En dit hoort ook niet echt in PMG.

Just pick a dead end and chill out 'till you die.
