View the updated project log on my personal site, XodusTech.com I built one a while back but lost it and decided to just build another. Basically this device takes a car's electrical socket and gives you a firewire port. Since all iPods have the ability to charge from a firewire connection this is ideal. Also the iPod can take an input voltage on the firewire input from like 7-30 something volts. Here is the first installment: So I had one of these laying around from god knows what. You could find one on any old cellphone car plug or other such device. I also found a Firewire jack in my spare parts drawer. I am sure these can be found on any old firewire card or front panel header Next I hollowed out the plug, mine had no circuitry, but if yours does just remove it. Next is to mill out the hole at the end to let the jack fit inside. This is a mockup of what it should turn out like. Next it was time to solder on some wires to my Firewire jack. Red for +12v and black for ground or common. I will update soon with the rest. Thanks for taking a look
This apparently was not too popular, but I update anyway with the finished plug Here is the plug all soldered to the contacts in the car plug I then Superglued the contacts back in the plug I then superglued the firewire jack onto one half of the plug Picture of the iPod firewire cable all plugged into the new adapter I hooked it up to a 12v source just to test, and all was good. I even kept the fuse in the adapter just in case something went wrong Thanks for taking a look
Pretty sweet idea there, this may not be popular but I'm a fan of it and all those other from-what-you-already-have mods
no stabilisation what so ever? just 12v into your ipod? pretty hardcore if you ask me... is it possible with usb plug?
If it were usb it would be a totally different story. Keep in mind that the ipod itself can take an input range of about 7-30v on the 12v line. Most modern cars also stabalize the power running in the car anywho. That is also why I included the fuse assembly in mine. I used the old one for quite some time without any issue ever. If you were building a usb one I would reccomend finding an old cellphone one that outputs like 4.9-5.1 (obviously ideally 5v) and remove the cord and build a usb port onto it. The reason is that you want the switching mode kind and not a linear regulator like a 7805. The 7805 will just get really hot and will be hard to fit a heatsink inside the little case
