Well as it says, tie ALL unused inputs to ground, but I dobut that is a problem in your case. Make sure all pots are receiving +5V (+/- .2 is OK) and they are all the same value... it also depends on how many pots you have connected, but I dobut this is a noise issue as well... I hope someone else from the forum takes a look at this

Rectifiers heating up even a little bit seems strange, unless there is a short, but you'd probably notice that when yout transformer heats up and starts to fail... Rectifier is all in the correct position? If it's DC, bypass the rectifier, just be extremely careful of polarity

Make sure you dont have any type A pots, and that they are all 10K type A is logarythmic, type B is linear... (At least the kind I ordered from futurlec, manufactured by alpha)

Always give voltage regulators 2 volts more than what they put out. Always. Thie means, never feed your core 5, even 6 volts, it wants 7+ SID module wants 11 (for the newer SID and 14 volts for the older one

Ok this is what you can do to easily solve your problem: Buy a new PIC (I am), check all connections and read the schematic of the core module. Make sure you know what you are doing with the voltage regulator holes... Voltage regulators usually go ICO (Input, common (ground), output) when you are looking at it... You want to ground the middle pin, put 5V into the output pin, and test socket voltages. I wish you the best of luck, removing this PIC and getting a fresh, tested one is good but costly... It's what I'm doing :-/

I remember someone saying that, cant find the post... Someone said they wind them higher because over time the voltage drops with wear and tear but that's irrelevant now

Ok I have time ro run to radioshack before this ebay auction ends on that C64 PSU... the nice thing is that they have a 2 amp transformer for $10! Anyway! I dont want to burn out a regulator (I hear they have temperature shutoff) I hope that will tell me if they're getting too hot...

No one has done interface with midibox, it is possible but I recommend seeing what highlyliquid has to offer in terms of midi -> SnS You could use a midibox to send midi to the SnS, and I'm sure you could come up with a super-cool panel layout to control it as well!

Actually, you might want to disregard my earlier post, Mr Modnar said earlier somewhere that rectified AC will be higher voltage DC than it is AC so... I could use a 12.6V radioshack transformer? Rectify it, get 16-17VDC (nevermind this absurd calculation), and power a 12V SID? Or... pay $20 ($10 shipping!!), get a C64 PSU, plug AC into the SID board and use 5v for core? The C64PSU isn't nearly as cool as wiring up a power-plug and everything but I guess it'll be fine >.> DIN jack < mains jack! ----EDIT you replied while I was posting! ----EDIT Damn edits Can I use a 12.6VAC source for both modules? Simply enough?

I know you all have answered this before :'( I know nothing about AC but if I buy a c64 PSU, can I just hook it straight into the SID board? I've looked at the optimized PSU schem but I dont know how you'd get 14V from 9V! (as it shows)

MAX525 looks like it could do video... I didn't entirely read what it was but the total harmonic distortion (distortion of incomming analog? seems fine until about 50khz, where it shoots up pretty sharply. Luckily, maxim is amazing with samples and if they will let you sample a chip, they ship them in nice little boxes and everything... What would you use the max525 for? Analog->digital ins for a pseudo DIN input? That would be pretty cool to have the monitor's signals converted to digital or whatever but what were you thinking?

These versions are software, not hardware? So it'd just mean a code upload mostly?

The driver being written... maybe with super heavy modding to the whole core module... I dont know where this app spits out its signals, but you could use an AOUT for VGA, which would be 0volts (zero brightness) to .7 volts. Of course R, G, and B, and 2 syncs... It could be done!

I have used search and I know the SID has polyphony, how do I send the midi messages and notes to go to one single oscillator? So I can have drums, bass, lead, all playing from the box at once?

Excellent writing, I've made mistakes too, I'm glad your box is working! Also, panel mount is almost always < PCB mount... But PCB mount is more expensive PCB mount lets the copper do your wiring for you! all you have to do is solder in, drill to case, done! (I wish I had an etching setup so I could do this :'()

See? My math is terrible. Anyway, glad to hear it's working

Less CORE PCB's, more PICs. It's too bad you have had such a hard time uploading, I'd recommend just getting a new pic, and checking your boards... Smash's are pretty straightforward, I even swapped some caps around on the SID and it's like I have "ghetto bass" as they call it. If you are getting the upload request sysex string once, that is good, if it is repeating, that isn't bad. If you can use MIOSstudio, that makes everything a lot easier... When you upload code, the core is supposed to respond with a checksum, MIOSstudio will verify that checksum and continue. I dont think it'd be a computer or interface problem (by the way @ up, I uploaded code with an old m-audio device)

Pressing all DIN buttons drawing millions of amperes causing the end of the world?! Math time! V = IR 5 = I10000 I = (5/10000) I = 5mA per button... * 128 5*128 = 640 640 for din, + 500 for core and LCD That's over an amp... if you short every DIN thing... Without resistors, it's be hell. My math is also probably wrong, I just wanted to find out... it could be .5 mA

Thank you for the reply, I dont know what could have possibly gone wrong but really I think your solution is the best idea... So... the pic and LCD should arrive in a few days and if they don't work, I am going on a school shooting. but they'll work

Hey, My midibox SID worked 2 days ago, and I was messing around with the LCD. Before this, I could play the SID and everything. Everything was perfect, I could upload code, display messages and everything. Yesterday I forget what I was doing but anyway... Now I have disconnected the LCD (I am ordering a new one for other reasons) and the DIN and the SID and I think it has the code on there for the sidplayer. The problem is, when I had the LCD on, it would display a 1x20 line of blocks (it was not a brightness/contrast thing). That's fine, I'm getting a new LCD but the real problem is that my core won't send me an upload request when it powers on... The only reason I can think this would happen is that my heatsinked LM7805 (or 7905 I forget) was left on for too long and got a capacitor too hot or something but I highly dobut this. So now everything is disconnected except for the midi in, midi out, and power to core... I can't upload code because core isn't sending midi out. I dont know what else I can say to help :-/ (btw, the case/box I made is looking good ;)) ----EDIT I have a silly scope I can use to check core pins if you know of any that should be sending midi messages or whatever, this is just very dissapointing because I was having such a great time! (I am 95% sure it isn't a software problem) Measured Tx PIC pin with SillyScope and it's a constant 5v (I am sending LCD messages from MIOSstudio) Measured Rx pin and it's sending data Shorted the 2 and got a loopback (midi out from MIOSstudio came back through in) So it's not my midi interface, I really think it's a PIC problem and I have ordered anotehr from smash but this pic + LCD is a nice 15$ mistake :'( Would reburning the PIC be possible?

Panel mounting everything used to be a favorite of mine, but the wiring is that kills you. Also, panel mounted pots + switches turn if they are roughed with... Meh and meh. Always go with ease over convienience... I get my panel tonight hopefully! Also, good luck with upload

Well I should find offset in a main.asm (I'm building sid and I need to move second line one pixel down)? Also, running off of a 15 volt PSU, I can power core and sid parallel if core is heatsinked. A homemade heatsink made out of tinfoil would be enough but lucky me, I had one laying around. No components are hot either which is neat (or dare I say cool?) Not even the sid is heating much

All of my problems are gone except that The bottom character line is shifted one pixel up... Is this because I am running 2x16 LCD programs? I just have the lcd connection test running Also I am having a hard time overwriting this program code with MIOS studio. I am trying to upload sid application but the core never asks for an upload, I have tried restarting core and everything --------edit NEVERMIND! Everything working well except pixel shift... I have to change around main.asm of SID app and see if that helps but other than that, I am done the core! Woohoo!

I have the 2x20 LCD from smash. Unfortunately, the pin diagrams must be beyond me... I measured some digital voltages (all vss and vdd are good) and they are all low... I thought MIOS sent some text out... I need to configure for a 2x20 LCD... I'll do that for the sid application. I dont have visual studio ATM so I guess I'll compile with MASM? I have TASM but I'll use MASM.

No one can roffle more than I am right now. I put the optocoupler in backwards. You know... this wouldn't be the first time I've reversed IC's! Core is uploaded! LCD interconnection test uploaded! Test FAILED! I swear it's the wiring... I build sid this aftenün!
