Just showing a mod I recently found out about. I've installed an SD card slot in my Dreamcast to allow booting games and homebrew from a regular SD card. I've not seen too many videos of this mod and it doesn't seem to get a lot of attention so I though I'd do my own.
Parts I used were from Maplin (UK electronics store). The following are the exact parts I used in this video. 1x Electrolytic capacitor 47uF 25V (Maplin part #VH32K) 1x Decoupling ceramic disc capacitor 0.1uF 50V (Maplin part #BX03D) 1x Metal film resistor 470ohm 0.6W (Maplin part #M470R) 1x 3mm LED (Any should do - for example part #N20FN) 1x Stripboard (Maplin part #JP46) 1x SD card interface - I bought a cheap multicard reader and gutted it for parts.
Stripboard Layout I designed using jj1odm's schematic http://i827.photobucket.com/albums/zz... (My first attempt at designing a stripboard circuit - might not be the most efficient layout but works fine)
