EUzebox simple hardware mods

[schepers_cp]

hey all, i was busy modding my euzebox just now, it includes a power switch, so you can manually turn the console on or off fully, and an usb to isp module, all hardwired to the board.

so i don't have to worry about power consumption and finding my usb to isp module anymore~

and ofcourse some *ahem* high quality pictures for you x)

..and an usb to isp module, all hardwired to the board.

Now that is very handy, nice thinking

Awesome idea for the on-board ISP!

[schepers_cp]

thanks all, but since i installed the isp, i have some trouble flashing games... like with the mario demo, it crashes the console when i load a map. :/
so i need an isp enable switch for all wires or something, thinking for an effective way to tackle the problem~

[uze6666]

Yeah, I got that some times, The ISP lines are interfering with the Sd card. Never got to look into it.

[schepers_cp]

my temporarily solution is to use relays for the data lines and a tumbler switch to trigger all relays to enable the ISP~ only downside: it doesn't fit into the case anymore XD

maybe i need to get smaller relays? ^^;

[schepers_cp]

also, it might be usefull to have fuses (fast blow ones of 1A) between the 5V rail coming from the 7805 and all other components.
not that i did blow my 7805, but just for those who short-circuited something~
also, expansion boards are a must for DIY people like me, because the euzebox expansion area is waaaay too small~ xD
(like somtething stackable?)

EDIT:

just made a first proto pcb for a quad 5V relay based on this schematic:
