hi all
i ve finish to build a midiboxsid

1 sid modul
1 core
1 din
and
1 Lcd 2x16
i ve burn 3 powersuply adaptator until now
i dont understand ! ! ! is it Normal
is the lcd or the sid modul can Kill it Juste like this
Because I dont think there is a shortcut Inside !?!?!?!?!?!?!?!?!?!?!!!
H.E.L.P
Hi,
No - This is not normal. What kind of Power Supply do You use? The combination of the modules and LCD should not take more than ~1A current, how much is your adapter rated for?

p.s. Some PSUs have thermal fuses in them, so they switch off if loaded too heavily and back on after the PSU calms down..

i ve burn a alesis adaptator of 9vac 0.78A 7va
a nintendo adaptator of 9v 1.3A
and a 12 v 300mA
there is no shortchut between the + & - on power suply!!!
Then there is short somewhere in Your boards.. do a visual inspection if you can find a bad soldering and then use multimeter to check if there’s short circuit somewhere.

the most strange is
that everything si working well
"exept the filter (it was working very well, good cutoff, and after
some notes it was very bad <,???)"
the sid is not geting hot , neither the 7805 or 7809
??? i think i must remove everything from the box and test everything
:-\
i notice that adaptator burn only if i play sound
out of the sid.

You have a power and or ground path from your SID to your amp, or your CORE to your PC, or both, or your CORE+SID are making a path from your PC to your amp, etc.
The burnt out wal wart thing is totally related to your “display stays lit” issue…Did you lift the ground on the CORE MIDI yet like I suggested on the lit display thread?

no
the lcd was break and i ve exange it from my dealer
my sid can stay power on 2 hours without probs

(((the power suply is in ac, but when i reverse the polarity
it make a shortcute ))) also this , i dont understand .
