Yeah that checks out fine too. I'm reading 5V when unpressed and 0V when pressed on said button DIN pin. I'm thinking it makes perfect sense if the 74HC165's are malfunctioning, but it's not likely. I mean all 12 of them?! There's definitely 5V going through all pins except 2, 7, 8, and 15. I've got 0V on 7, 8, and 15 and like 0.15V on 2. I'm thinking it's gotta be some issue with the core or the software because everything else checks out.

I busted out the voltmeter and there's definitely some current going through the DIN, but this brings me back to my original assumption: maybe I just don't know what the hell to do with a button. My camera's not working so here's a pretty ms paint pic. Right? Wrong? Retard? I've tried all other possible combinations in case my logic, shown in the pic, was wrong. I've tried everything else. I'm at the brink of nothing can be done about it.

Ok so I fixed the heading on the resistor networks and still absolutely nothing. This is freaking BS. Everything is setup absolutely perfect. I've got 2 SIDS running from a core so there's nothing wrong with that. I refuse to believe that all 3 of my god damn DINS are duds. Geez WTF?!

Here ya go dude. I found this really helpful when putting together the C64 optimized version of the PSU. http://www.danielprice.org.uk/synth-diy/sid_2.htm So you follow the above guide precisely and you've a fully functioning optimized PSU. Then later after everything checks out between the PSU, SID, and CORE you can throw in that additional cap at the end, shown in http://www.ucapps.de/mbhp/mbhp_8xsid_c64_psu_optimized.pdf

Yeah there's a freaking arrow pointing right were the marked spot needs to be. Geez. ::) Thank you...so much. TK should put in a gold star system or something in the forums. You totally would've got like 50 for pointing out the bull crappingly obvious to my retarded ass. This is what happens when you don't go to university. ;)

0)Yes 1)Yes 2)Yes 3)Yes 4)I hope so, I used the ones that come in the kit from Smash. 5)Yes, I broke apart one of my buttons so I could be sure where the pairs are. 6)Yes, I actually shocked myself in the process. Of course I'm using this PCB http://www.avishowtech.com/mbhp/mbhp_dinR5.html The only other thing that might be it is, and this is a noobie noob thought, the kit came with the bridge resistor things and they are not all facing the same direction. This is silly because I'm 90% sure that the heading doesn't matter.

I get no response from that application either. What else could it possibly be? Again I've checked the connections about 10 times. This just doesn't make sense.

I've tried every which way before I posted and I suspected either I may not by doing something right or have the wrong buttons (even though that's retarded) It's my damn DIN. I honestly don't know. I've been at the thing for hours trying everything: Retracing the connections. Everything is right. Checking the forums. Read to page 20 before I quit that. TK has DIN related troubleshooting guides in the portal section so I thought maybe it was the hex file I loaded into the PIC. I originally had the TK setup version and the .asm file had different setups in it for the DIN pins so I changed to the 8580 hex and very carefully read the DIN lines in that. Everything matches but I get nothing. Anyone who had a similiar problem in the forums either didn't give a solution or the solution didn't work in my case. I have 3 DIN modules and tried them all and still nothing so I know if it's some hardware thing it's unlikely to be in all 3 of them. This is seriously driving me up the walls. I've even tried talking nicely to the DINs and they still won't cooperate. The sacrifice made to the circuit gods didn't work either. This is much more than a button issue here I'm sure. I've been at this for five hours. :'(

I've searched everywhere for an explanation on how exactly buttons work. I ordered my buttons from Mike's store and they have 4 pins on the bottom but the schematic for the DIN show only places for two. It's my understanding that these are momentary push buttons and that, I think, the four pin buttons are tactile pushbuttons. I honestly don't know the difference but I know that with four pins to choose where to solder the wires into, when the schematic only shows two, I'm pretty sure I have the wrong buttons for the Control A setup. Or at least don't know what I'm doing. If I've offended anyone with my electronic ignorance, I apologize. :-[ If anyone could please tell me what's the deal with the buttons it would be greatly appreciated. Thanks, -Karac-

Yes?! http://www.ucapps.de/mp3/midibox_sid/mbsidv2_superpoly_experiment.mp3

So I'm curious, with all the bright, beautiful, witty and, seemingly, intelligent people lurking around the forum. Curious as to what they do for a living; what brings the money in/what will eventually bring the money in/what does everyone typically do day to day? This is the job/occupation/career/I actually still live in my parents basement/school/blah/what I do in my free time thread. I'll start with me: I"m a student at the Defense Language Institute in Monterey, CA learning Korean. I am in week 57/63 of the Korean course and am nearing graduation. I study nothing but Korean 7 hours during the day and 3 hours average for homework at night. I should study on weekends too, but for the past month they have been taken up with Midibox. ;D

A beatboxing baby

OK so I do hate dragging this on but, in my own defense, I did search the forums prior to this initial post. I did find many topics regarding this issue and, no, there were no answers. The closest I got to was http://www.midibox.org/forum/index.php/topic,9672.0.html, which the title is "Help needed connecting Smash's SID to Mike's CORE", so I thought, "Great this is exactly what I need". The poster solved the problem but never said what he did to fix it. Someone actually asked later after the subject was changed what he did to fix it and still no answer about it from the poster. After that I posted here to be told that . And in an attempt to counter the, in my opinion, uncalled-for-sarcasm (if someone has to say then the initial comment was meant to make someone feel like an idiot), I deliberately wrote a self-righteous response, hence misrepresenting my situation. It's quite trivial to drag on something like this, but I feel I've come across as being a bit petty. I apologize. Smilies for everyone!!! :) :D ;D 8) 8) ;D :D :P :P :-* ::) ;D :D :) :) ;) :D ;) :) ;) :D ...and for future reference for anyone searching the forums, here is what i ended up doing for a Smash's SID to Mike's CORE problem: The connections are like so: Core: Sid: Rc Rc Vd Vc Vs Vs Md Sc PWM Clk So So Mu Mu (Nothing actually deviates from the physical placement of the wires from the psu schematic) ...however this didn't work for me and gave me problems, however I found that when using this http://www.ucapps.de/mbhp/mbhp_sid_c64_psu.pdf power setup (as I intended to only have one SID at first and then compensate with the http://www.ucapps.de/mbhp/mbhp_8xsid_c64_psu_optimized.pdf setup later when I added more SIDS and CORES) is what was giving me the problems. So I used the latter of the two power setups and everything was working like it should.

I just bought an M-Audio USB Midi cable yesterday and had to fiddle with it for at least 2 hours. It was doing weird stuff and wasn't interacting with my core module. I looked through connections and everything was good. Turns out it was a minor driver update and everything was good after that.

How does it feel to be a god walking amongst mere mortals? Today I got some sounds coming out out my MBSID, finally, and after everything I put into getting that far, I must I'm absolutely amazed at the design. I mean, the fact that this design was put together from scratch is absolutely incredible. Even more so is that you completely documented everything for everyone else. Three months ago I couldn't tell you the difference between a resistor and a capacitor, but here today I've made a MIDI synthesizer from the old C64 Sid chip. I mean, three months ago I saw the bass demo on youtube and thought, "Oh shit, gotta get me one of those." Come to find out it's a DIY project and I don't know jack about electronics. All in all I'd just like to thank you for the awesome work you've done and the amount of material you've made available for everyone. And when you do finally take over the world with your SIDTanks and MIDI Robots, just know that I'll be on your side. -Karac-

Thanks for pointing me in the right direction, SLP, however replies like yours are what is unnecessary. And yes, I will search the forums harder from now on. I get the point.

I'm using the Core PCB from Mikeselectroniksite and the Sid PCBs from Smash TV. The Letters from J2 of the Sid module and the J10 from the Core module don't match up, they're different letters. The new style SID PCB have a 'clk' and got rid of 'md' and the 'sc' is in a different location than shown through the http://www.ucapps.de/mbhp/mbhp_sid_c64_psu.pdf layout. I tried following the schematic as if nothing were different but after I do this, I don't have the correct voltages and the lcd doesn't show 'ready' after the copyright screen. Please, someone, tell me there's a way around this besides buying a core module from Smash TV to match the smashtv sid module. :-X :-X :-X :-X :-X :-X :-X :-X

oh no i didn't take it seriously at all. I actually have the exact same thoughts in my subconscious and seeing it made me wonder. That's all. You should put it back the way it was before. ;D

why not go to university? :)

What's up with this, then. The mixer you gave shows the pots being used like you said, but what's up with this stuff.

So i'm thinking maybe this would be a suitable way to do the pots. I know the best to find out would be just to try it, but I'm wondering if anyone (everyone here knows more about this stuff than I do) could tell me if this even makes any sense.

ok...so if i were to use this circuit for making a mixer and, say, wanted to throw in some volume pots for each input, what would be used for ground??

oh sweet! God it's so simple, thanks!

...don't really know how it would be done. I think it's great that the four different SID chips that I use can be used as four separate channels, however I don't have a mixer at the moment. Therefore, for the meantime, limiting me to only one SID at a time. I noticed there are two audio IN OUTs on the SID PCB so...I'm thinking that in addition to the four OUT jacks that I could combine the other OUT portions of the four PCBs into one OUT jack. If possible, how would I go about doing this? I'm still fairly new to electronics. I'd be grateful to anyone who could help out. Thanks everyone

these are some noob questions but i seriously am stumped...being almost completely new to electronics. 1. the '' http://www.ucapps.de/mbhp/mbhp_8xsid_c64_psu_optimized.pdf schematic '' schematic of the c64 psu method has two symbols i don't quite understand: the squares with circles in them labeled 5vdc and 14vdc. what are these exactly? are these certain parts which I can buy or are they supplied in a c64? i understand that they supply the regulated voltages to the cores but i'm clueless as to what these would look like physically or what they are exactly. 2. the different colored wires in the schematic, do they indicate any other kind of special wire to be used? or are the color codings for organizational purposes? I don't quite understand the different properties of wire of what kind are available and which kind i need in certain projects. i noticed ribbon wire is used with midibox sid but there are also thicker wires used, like with making connections on protoboard with the c64 psu. i can't find a url that explains this. maybe because it's common knowledge. i really don't know. if anyone could help me out here i would be forever grateful. the power supply is the main obstacle for me to begin building. thanks everyone
