I introduce this new mods board for the WRT54G/GL: http://berlioux.com/electronique/wrt-sim/wrt-sim-en.html Features: - 5V regulated power supply - RS232 line adapter - 1-wire adapter for thermal sensors - SD/MMC mod The description of the board includes the diagram, the printed circuit board, and all the needed configuration documentation to make all the features work. Everything has been thoroughly tested. Feel free to build your own! French translation will come soon. -- Marc BERLIOUX "La simplicitÃ© est le fruit d'un long travail"
