Now the power connector and finally the header. Now the microSD card slot - note that you don't have to add this unless you want the audio jukebox features.

Let's start by adding the 10k Resistors, they're marked with Brown - Black - Orange stripes and the 22k resistor Here's the circuit we're going to build Ĭheck to make sure you have everything you need, warm up your soldering iron, and continue to the next step The kit comes pre-programmed, but if you're building it yourself, you can grab the sourcecode right here. The kit also comes pre-programmed and includes a USB cable and mounting hardware.

Thanks Everybody!Ĭontinue on and I'll show you how to make your own!īelow are the parts you'll need to build your own Car Kracker - We also offer a kit that includes everything you need right here. The Car Kracker builds on many people's work - Many thanks to Dr_Acula for respinning RS232, Jochen Navcoder, the BMWCoders forums, Rayman for audio playback, e46fanatics, and bimmerforums. Changing preferences (like turning off the door gong) just updates the settings memory, the firmware doesn't change.
