hihi

im wiring up my SCM and am confused about the 3 position switches
you mention that you use a 1 pole on-off-on
how is this done?

does that mean that one state is always on?

I am sourcing parts and working out a panel for this module right now so the issues associated with it are on my mind. I am using rotaries for those three but you can definitely do it with toggles. Here's a link to fonik's schematic:

I think he posted an english translation on the em forum once but I can't find it - the picture tells the story well enough though, I think.

Good luck,

Mark

you could use any common dual opamp with same layout. i think i used a TL072.
what's the issue?

Hello all!

Not much talk about the Super Controller for some time now... what happened?

Did anybody succesfully build and use one?

Any samples?

Have a nice weekend!

Matthias, could the error be in the one we found with the original pcb payout? Remember there was an error in the schematic as confirmed by TH? I believe it was a transistor.

thanks for the suggestion.
i can remember that error, however, the error was in the original schematic from the book and on the 1st prototype accordingly. this has been corrected both in the redrawn schematic and in the manufactured PCB.
since i made the new design from the working redrawn schematic/PCB this should not be the problem.

in fact i see 5V on the 5V rail as long as no SN76477 is in the socket. as soon as i put it in the 5V rail changes to 7V (sic!)...
alas, i had the wrong socket on the PCB in the first place and had to remove it, which did not work well. i guess i did something to the PCB when removing the socket. i am currently assembling the spare PCB. hope it works well then...

so some progress. a little. i now see the 5V. obviously a fault/short in the PCB after removing the wrong socket... Rolling Eyes

okay. the sn76477 ist still not working though. ridiculous. more checks to do...
