This pic is particularly awesome:

With picture filesizes of 20MB -900MBs per file, and such high resolutions on that page,
each sid chip model could easily be reproduced.

This thread would be worth a read if you havent already:

Although you'd experience different results with those cap values on a 6581 i'd imagine.

i as i intend to build a replica control of the motu bpm software, i want it to look exactly like the unit in the software
Nice! You might have a problem having the faders that small though.
Although actually now that i remember, i always expected the mpc pads to be much smaller than they actually are in real life, and keep forgetting.
And i guess you could always use knobs for the envelopes instead.
yep im mad but then all geniuses are start raving mad, ask tk... hes certifiable!!! lol!Id love to see TK's crazy side actually!
Hes just so such a clinical, professional engineering machine on here that you dont get to see the crazy side!
-
God damnit, so close i was but no cigar!
I thought of using the c64 keyword instead of commodore but it just didnt seem to follow through!
-
Thats cool!
I'd be worried about dust though, its annoyingly dusty in my room.
Any easy ingenius ideas to seal the opening space with the minimum amount of effort?
Would be a shame to cover up that sexy pcb though.
Hmmm, a perspex window would be in order so you can still see that goodness!

I'm gonna make a four-finger SID ring and punch my supplier in the face with it.
With the IC legs facing away from your ring right? ;)
Actually someone made a commodore ring from the Commodore key on the keyboard,
but i'd be damned if i can find it in the search!
-
It might be a good idea to use a transformer or power supply that can accept both 110V and 240V like most transformers tend to do these days!
Although you might never use a 110V supply!
-
Just finished the core module 99%, all thats left is to solder are the midi sockets.
I just tested it for 5V between the 4 pairs of pins TK and Jim Henry suggested,
and it passed. :D
I also spotted a minor mistake in Jim Henry's Assembling a Midibox Core PDF
Edit: It appears i had the older version with the error in it!
I was absolutely baffled as to why i wasnt reading any voltage between those 2 incorrect pins! :-[
Must stop trying to save bandwidth and start viewing pdfs online, instead of downloading them!
-
Oh and please note that the diagram of the Pin out for the C64 PSU socket is wrong in the diagram.
The GND lead should be connected to the bottom middle pin.
I could of sworn i got 5V DC when testing the top middle pin before,
but I didnt this time so I switched to the correct pin.
-
Well finally i managed to get the PSU finished, and got a stable 14V and 5V dc reading.
As many have said before, BUY A DAMN GOOD SOLDERING IRON!
It makes life 10 times easier.
Because im using a panel mount Socket for the C64 psu,
ive connected it using sil headers for the AC (yellow wires) and DC lines, (black and red wires).
So i can detatch it and use it in a different case in the future (i think ive thrown out the top of the c64 case! damn)
Also, i broke the original C64 LED, and tried using a Green LED from an old PC which tends to get hot, so hot in fact that it shines Amber instead of green! :P
Anyone know off hand what rating the LED should be to replace the c64 LED?
It aint pretty but heres the pics:

Nice! The red theme reminds me of an Access Virus.
Did you use .100 spacing cable to connect the PCBs? If so, where did you get it? I couldn't find it at Mouser (it's there somewhere I'm sure) so I just used standard IDC cable.
Thx again re: the 8-pin connectors.
SmashTV has them also, might come in handy if you need to buy some other stuff:

This is from a local electronics store in Australia.. A touch expensive, but delayed switch on / switch off, low profile, zero heat.
I'm sure you could find something similar locally.

Thanks mate!
Ill be using a c64 psu but this will be great for future reference.

Awww, the bridge rec looks so sad.... :(
Sitting there with its little melty face and stuff.....
(I think im going insane ???)

I used a switchmode PS in my SID synth..
http://www.midibox.org/forum/index.php/topic,12413.75.html
The Power Supply I used has a 5v & 12v output.. I regulated the 12v down to 9v for the SIDs.
After A-B'ing it with a commodore 64 PS and the switchmode PS and I could not hear any difference in background noise etc..
Just my $.02, your results may vary.
Regards
Mike
Mike any more info that psu you used?
Model name, part number or whatever?
Sounds like a good one to go for, or else maybe its just that the optimized circuit is really great at well....
"optimizing." lol

looks like a Spring Reverb.
Ah so thats what a Spring reverb is!
I always thought it meant a certain type of reverb setting.

Foona somehow i only managed to see this thread now, welcome back man!
I spotted this video a few weeks back and its so damn good!
So uplifting, and i didnt even realise it was based on I'm Yours til i read the description.
Its a real feel good tune, well done!
Btw, Whats that little box that makes sounds when you hit it?
Its dope!
-
This video is a masterpiece in more ways than one.
I absolutely love your music too.
Thanks for putting the time and effort into it.

With my suggested wiring of feedback pots for MB-6582, you don't need a switch, unless you want to add audio in jacks.
Ill be wanting audio in alright, i might as well use that jack plug shown in the alphamod for when i wont be using the audio in. Cheers. :)
-
-
I think i found a few:
Try getting them in dual gang, and getting them to fit in an mb-6582 though!
-
LOL
Hehehe, yo wilba? whats up with the phantom edit on my post? ;)
BTW, Mr. Jams, would be so kind as to tell me where you got that 500k potentiometer with button?
Cant seem to find one on ebay since potentiometer button doesnt reveal anything!
Cheers

His LCD is actually not correctly adjusted for brightness/contrast, see how dark the squares are in the background?
Yeah i see that, but the forecolour just looks so much better than the one in the CF pic, id almost prefer to see the squares rather than have a dull forecolour! :P

All the holmies are doing it...
LOL
Another 50 SIDs have arrived!!!!
in Fleamarket

LOL! You so cerazzayyyy.
