* Do you want potentiometers or encoders? * You do want the display. It's really nice to have a display for debugging purposes, and generally helpful after debugging. * 20 buttons -> 1 DINx4 module * 17 + 4 = 21 analog inputs -> 1 AINx4 module * 8 digital outputs -> 1 DOUTx1 module (get a DOUTx4 for expandability) * You also need a power supply More LEDs are generally nice for more visual feedback, too. Throw together a mockup of the panel, that'll help us find possible problems a lot easier :) edit: fixed DIN/DOUT typo mixup

Acryl: Ponoko (die haben die Panels für fnpSID, für meinen Modular Synth und für alle sammichSIDs gemacht)

Purrty! I like it! :flowers:

Short answer: No testing w/o core and sid module unless you have a different machine to test them in (c64, sidstation, hardsid, ...) :)

Na sicher doch. Den Rest klären wir via PM/Chat ;) slp.zip

Oh noes, don't ask him direct questions, you're basically forcing him to return when you do that ;)

Welcome aboard, ANdrw :flowers: 70% of your questions are answered in the first thread you linked to. 29% percent are answered on ucapps.de. The last 1% is this: Depending on what you have in your spare parts drawer and where you wanna go somewhere between 0€ and 42,000,000€. With the box you linked to I am guesstimating 400-500€.

Yes.

You'll be missed. :flowers:

49/18 is the package. They have the same footprint, either one will do. The HC18 is a bit higher, and the 49 is the flat one.

Pretty little box :thumbsup: A note to everyone: If you pronounce your box MBOTW please follow the naming convention of the topics :yes:

+1 on both. It's annoying but I think it also helps prevent semi-random quick hack changes :) It's a double-edged sword :flowers:

No worries Tim, shtuff does happen :)

Let's have some different genres here :thumbsup:

Well. You didn't change anything so it's unlikely you fixed anything. Follow the directions that TK gave you and report back with the results.

I already moved the topic ;) Typically I'd consider this kinda post semi-spam, but you asked so nicely :flowers: Fire away!

Look at the schems of the modules, get out the datasheets, check for max current draw of the active components, sum them all up, add a good bit for good measure, get back to us with the results :)

Somewhere in the depths of the sidplay source code I've found some references to the jumps, which seem to be the normal non-linearities in 6581s. Supposedly they're pretty much completely gone in 8580/6582s.

50VA means >2A per rail. That's a lot. That's way too much for an mbFM. You won't need more than a few mA per rail as the only thing the +-12V supply is driving is a bunch of TL074. So to be on the safe side and have more than enough reserves let's say 300mA so a 300mA * 12V * 2 = 7.2VA toroid will do.

Account issue fixed. Or edit the old posts and click "use full editor" to get to the attachment options.

All the pics in all of your threads are dead. Would you mind attaching them to the posts? <broken-record>offsite doco bad</broken-record>

Thermals bad, mmmkay :) Ich gehöre zu jener Fraktion und löte seit jeher mit meinem ERSA 15W Kolben mit Bleistiftspitze alle Massepins ohne Probleme. Lötkolben schräg - also etwas flacher - ansetzen kann helfen :)

Für die Platine schreib Dich einfach in die Liste für Spares ein. Ich hab hier noch 2 überschüssige gm5 von TK, musst Du ihn fragen, ob Du einen haben darfst ;) Gruß, nILS

Fein geworden! Hatte ich auch mal überlegt, war mir dann aber irgendwie zuviel Arbeit :)

I suspect your PSU circuit/wiring was off... Here's your 10-step program to happiness: 0) Take decent pics of everything and post them here 1) NO MORE POWER/ICs ON THE MODULEs UNTIL YOU FOUND THE PROBLEM 2) Remove all ICs 3) Disconnect the LCD 4) Disconnect the boards from each other 5) Power up the core and make measure all voltages. Post them here 6) Unplug the power 6) Connect the SID module to the Core module 7) Plug in the power to the Core modul and check for the 5V on the SID module 8) Add the power supply for the SID, measure voltages. 9) Report back with the results For testing purposes(!) you can use that 12VDC wallwart IF and only IF it is regulated (ie delivers a constant perfect 12V). If that's the case you can simply wire it to the core's J1 for the core power (do not use the LCD with it for now because too much current draw will give you a pretty hot regulator), and also wire it directly to the output pins of the 7812 on the SID module (ground to pin 2, 12VDC to pin 3, see http://ucapps.de/mbhp/mbhp_sid_v3.pdf).
