LinkSys WRT54G(v4) SD/MMC Card Fits in Floppy Edge-Connector: You can attach a SD memory card to any homebrew DIY project that has a few I/O pins, using ordinary connectors you probably have right now. SD cards are very popular for this purpose, because they only need a few pins (using SPI mode), and can be driven with simple "bit-bashed" SPI serial communications protocol, using free device drivers.
