hi guys! sounds very cool TK :D btw that's a nice & slim looking design of your SEQ shown in the video edit: hehe, ok so i havent been on the board for a while... just found the bulk order, i should have known! :P

http://en.wikipedia.org/wiki/Software_Automatic_Mouth possible to do with MIDIbox SID? :D discuss...

hey good question, i experience the same exact thing w/ my PSU based on TK's optimized circuit. The only extras i have running is a LCD, 2 banksticks, and a power LED. I am using a c64 power brick to run my MBSID. more details on my build can be found here for comparison: http://www.midibox.org/forum/index.php/topic,10585.0.html I currently have installed a salvaged 6581 chip but soon i will be putting in a new 6582, perhaps it will make a difference? It doesnt really bother me but I'd like to compare notes and see if we can figure it out. I suspect that perhaps the cap's in my power brick or PSU circuit need to cycle once to charge & then hit everything w/ proper voltage on the 2nd... either that or the chip needs to warm up or something. Anyone else experience this phenomenon? edit: I'm certain it has nothing to do with SmashTV's kit either, it always powered up fine before. I only experience this since building my custom PSU & using c64 power brick.

oh yah, come to think of it there are alot of direct flights from AU to Los Angeles... http://www.latimes.com/business/la-fi-skies16feb16,1,1053087.story :P

:o alright! got my 10 SID6582's in the mail today! thanks Wilba!! now i can't wait to get the big MB-6582 PCB from SmashTV, hope he stocks it soon ;D

I call em 'me noodles' As in, I finally got an enclosure to protect me precious noodles! How's that? :P ;D

Hi everyone, thanks for all your replies! It's very nice to see there is interest in my modest little TupperSID in comparison to many of the masterpiece builds on the forum. (ahem, Wilba!) I was in a rush to post my first pics, and my last reply was done quickly on a cell phone so for that I apologize. Now I finally have time for a proper write up so here we go... First of all I built my SID and CORE modules from kits that I ordered from SmashTV and I've said it before and will say again, I am really impressed with the quality of his stuff. I highly recommend that any first time builders start by ordering his PCB's at the very least, they are awesome! Next, I bought 3 commodore64's on ebay to salvage for parts. The first one was the original brown style with a 6581 inside; I plan to use this case for my next build and the best part is it came with a nice faux leather dust cover! The other 2 were 64c's because i wanted to find an 8580 chip but no luck! I just got 2 more 6581's... oh well, I guess I'll have to live with the weak filter until the 6582's I just ordered from Wilba arrive, yayuH! Next I hooked up my LCD which was kinda tricky, I had to solder together a few jumper pads on the back of it to get it working but after a little experimentation it lit up and was looking nice. Check this out, you can see the part# incorporated into my frontpanel concept art: The actual part number printed on mine is longer... it's CFAH2002A-YMI-JPV, and off the top of my head I don't remember what the extra letters mean but I think it has something to do with language and voltage specs so be sure you understand what you're ordering. Obviously this panel is too large for the TupperSID... This panel is for my next build in the original c64 case which I will vynil dye either white, black, orange, blue, or something else (TBD). It will have 8 SID's and will be built around Wilba's MB-6582 PCB which I am really looking forward to ordering as soon as SmashTV stocks them in his store. Q: Where did I get my 99cent enclosure? A: The 99cent store of course! Yes by all means feel free to learn from, recycle, reuse, and implement any of my ideas that's the MIDIbox spirit! After all, this forum wouldn't exist if our founder Thorsten Klose had not shared his freaking awesome designs. In fact my PSU/Bankstick circuit is remake of another with plenty of tweaks and different layout to serve the purposes of my own design. Essentially, it's based on TK's Optimized C64 PSU with the Banksticks hooked up to the appropriate power rails, etc. This was my first circuit I ever designed using CadSoft EAGLE which I found to be a very nice tool. I have attached my layout files below for anyone who wants them. I think this PSU/Bankstick circuit is perfect for the beginner or minimal setup and if you use it please let me know what you think, thanks! - sonofdirt TupperSID PSU+Bank.zip TupperSID PSU+Bank.zip

Hey thanks, the display is a Crystalfontz. I got 2 of them on Ebay for really cheap by doing one of those 'best offer' deals.

the 99cent enclosure. ...and my custom power supply circuit with 2 banksticks:

Awesome, I can't wait 'til these boards are ready for order. Wilba's hooking me up with a full set of 6582's and my original Core and SIDv1 kits from SmashTV were of awesome quality. They were the green pcb's that felt like polished stone or something, can't wait to see the red ones, what type of material were those pcb's made of anyways? Thanks for working together on this one guys!

Hellooooo out there! :o sonofdirt lives! email sent! ;D

hey cool i've been looking for the simplest filter design for my mbsid too and i like what you've got here. I looked up the datasheet on that IC and it sounds pretty cool, looks like it can do VCO's, VCA's, VCF's, S&H, all kinds of good synth stuff! The datasheet shows diagrams for a few filter designs: Hi-pass, Lo-pass, and 2pole Lo-pass "Butterworth" filter. It also appears that the mini-synth designer drew up a circuit for Bandpass as well (im guessing it's the HPF and LPF wired in series?). Anyways good luck w/ the circuit and keep us posted, ill order a couple of these IC's soon and start breadboarding. It would be cool if we could make it a multimode filter, somehow switchable by MIOS & store settings with patches... Anyways, I intend to use something like this to completely replace the filtersection of my 6581 cuz it sounds like crap, especially the lower cutoff settings which come out all distorted for some reason (is that normal 6581 behavior?) I think many people will have interest in this as an alternative to the CEM/SSM filters because its so small and simple. Keep up the good work! ;D update: k so i've done some research on how to make filters w/ op-amps like this IC, check out section 5-8 of this PDF for lots of filter recipes: http://www.analog.com/library/analogDialogue/archives/39-05/Web_Ch5_final_PtB_F.pdf
