- as you can see, it uses a mere 12MHz crystal, yet also works (some times it kill the HID-manager, but often work)
- the leds in the last two pics are inside, no hole needed as the external cover is more-or-less transparent, just align it to a hole
Now how it's work?
If the hw armed by kbd_led-sequence (you can send the appropriate code by the included programs) then if the scroll-lock led is lit, after a pre_delay, the hw will send pls_cnt number of pulse with pls_ms rate. All 3 parameter is programmable via led-sequences (prgs incuded). All values should be in range from 1 to 254. (my current setting are: pre_ms=100, pls_ms=25, pls_cnt=150)
You can disarm also as in default, so it will not mess with the system and you can't activate it by accident.
I tried to include an automatic led-switch code to xorhack code, but it was mostly ineffective. So the best bet is to push the scroll-lock in the keyboard.
ps: the blaze ps2->vga adapter work with ps3 too - in game_os scrart/rgb 576p and 16:9 is the max (without YUV-RGB conversion), but in linux there is RGB 720p mode... and: if you installed the openssh-server, you can also connect to the ps3 with scp / winscp for file-transfer.
