Nobody interested? :-\ The link shows all the parts I sell, but anyhow for the rest (price shipping whatever): I am open for suggestions!!!

LOL *FIRST!* ;D ;) Anyhow *I did* forget that resoldering stuff you mentioned! ;)

Just to go sure: You did not put in the MAX-IC to the LTC, right? Is the correct display config chosen within MIOS upload (regarding the ID-header)? Weird problem anyhow. When you change the contrast, do the black blocks react (getting lighter or darker)? I would bet that it´s a cable problem. Really do check the cabling to the LCD again! Also for shorts (which sometimes are hardly seen). Get the datasheet @ Reichelt for your display and check the Pins of the LCD for correct connection. The 2x40 displays have two rows of 8 pins if I remember correctly. Perhaps the interconnection to the core is wrong due to that point (signals mixed up). *goodluck!!!*

If you can, you should check how much current your stuff is drawing. A core+LCD without backlight not more than 50 mA. Core+LCD with BL not more than 300 mA. Core+LCD with BL+ DINs+AINs not more than 400 mA (max), the same + DOUTs (depends on how much LEDs are connected) up to 600 mA or even more. If it´s to high there´s a short somewhere (ICs in right direction? Especially the Optocoupler?) For the heating of the 7805: Either go to a lower voltage (min. about 7,5 volts) or attach a heatsink. If it gets to hot or there´s to much current running through there it will shut down automatically. Are the caps in there the right way? They should filter the voltage to a stable value. If your stuff is drawing to much power (anyhow without shorts) try higher capacity values (e.g. 4700 µF as the first big one in parallel with a 100 nF one).

:-\ Keiner mehr Interesse? Warum? Bin offen für Vorschläge und Anregungen!

I don´t know if that´s normal, but if you want to do CC changes with the Encoders you should use MB64E firmware and not MB64. MB64 is thought to work only with pots as MB64E works with pots & Encoders. Check it on UCApps.de for more info: http://www.ucapps.de/midibox16e.html

It´s not the PSU in all cases. Higher chances are that it´s the shitty soundcard (I *bet* you´re using the built-in one, right?). That will also bring in noise when your HDD starts to work or even your LAN. I got a USB-Soundcard (M-Audio Transit) and since that point got no more problems anymore. You can get them for under 50 Euros, I think.

Yepp, that´s right. For the uploading via MIDI (first MIOS then the app): You´re not uploading the .hex files, but the .syx files. It´s all described on the page (you can also look at the wiki for that). For the app itself: Open main.asm in your editor. There´s a lot of stuff stated there and you will understand a lot more. So I do think that you can use either setup_8580_without_cs.syx or setup_8580_with_cs.syx just try out. Or you adapt the main.asm to your needs and convert it into a .syx file (How this is done is also stated in every detail on ucapps.de). Greets.

And what was it? Just curious... ;D

I think it could be a prob with the EOT message. It´s also stated in the .asm file: When MIOS is reading the *first* EOT message, it won´t search anymore for the correct entry. So all your needed entries should fill up the first lines of the table and the rest then should be filled with EOT messages. Not sure about that, but could be... *pushingthumbs*

No, this is absolutely normal. The SNR should be around 60-80 dB, so you still hear it. That´s the SID. The 8580s are a little better there (but still the same prob). But normally this is no prob, because if it disturbs you: You won´t ever hear it in an arrangement (with at least two more tracks playing) and *if* you here it, you can use a noise limiter to get it away (works out very very well in most cases). You even could think about an external hardware-based noise limiter behind the SID.

As this is your second thread here: Please do NOT write stuff like that into the news topic!! It´s thought for something else. Questions like that should come into the Testing/Troubleshooting topic or similar. This topic here is thought for *important* news about UCApps.de and midibox.org. TK is absent at the moment and so he won´t be able to move your threads to the right place, so please keep an eye on that. Thnx! /edit: Just read your apologies for that one! Never mind! :)

DONT TELL ME THATS AN EXCHANGEABLE SID IC NEXT TO THE LCD!!! :o I would freak out! Great idea! Really!!! Love it! 8)

You´re using these here very much, he? :P ( ;) ;D ) Back to topic: No, not any problem at all. Modulation wheels are nothing else than pots just with a shorter angle (something like 90° perhaps). The complete wheels should be sold somewhere, just google for it a little (try typical stuff like ALPS, Radiohm etc) - perhaps it will be a little hard to find them. If you find pitch wheels: They are TOTALLY the same (!), only with a little spring attached which can (in most cases) easily be de- and remounted. So in the end you only got four pots. For the app: Either the old MBPlus will do for you http://www.ucapps.de/midibox.html or the newer (and actually supported!) MB64 app http://www.ucapps.de/midibox64.html (which I recommend MUCH more than the old version). The rest is much of reading! www.ucapps.de But kind of everybody here managed to build his box(es), so you will do fine, too! :) Greets!

http://www.ucapps.de/mios_bootstrap.html ;D Reading! ;D ;) The bootstrap loader is burnt (for ALL stuff here). The rest (MIOS and then the application itself) are transferred via MIDI for easier updates (totally without burning or even opening the case of your device).

Jupp. DIN: 10k an 5 Volt = ca. 0,5 mA -> 2,5 mW -> gar nix DOUT: 220 Ohm an 5 Volt (4,3 genauer) = ca. 20 mA -> ca. 100 mW also die 1/4 Wattler oder 1/8 Wattler. @ljmarkus: Kann es sein, daß man ein Gewerbe haben muss um dort bestellen zu können...? ??? :P Kann mir nicht mal die Preise angucken.

Hi there! Perhaps some of you already noticed that I´m selling some stuff here on the forum (German Thread) as I first don´t need it anymore and second need money for my next project. I´m thinking of putting it here in english form also. The only point which hold me back up to now are the high posting fees to some countries. I just wanted to ask if somebody would be interested despite the high fees. Here is the link to the german topic: http://www.midibox.org/forum/index.php?topic=5328.0 The pictures and the table should be self-explaining and perhaps even the most of the stuff stated there on german. So if anybody is interested, I am giving away the whole package for 100 Euros at the moment. If anybody just wants a few parts, just contact me. I will translate everything in english then (if needed). Or for the unpatient: http://babelfish.altavista.com/ ;D ;D ;D For the posting fees: I am only sending via insured posting, as otherwise packages "go away" and are never seen again in a very doubtful way sometimes. ::) So that will be: most of Europe (Italy, Spain etc): 17,50 Euros some of Europe (just ask for) 26,00 Euros North America, North Africa, Near East: 30,00 Euros Rest (whatever that means): 36,00 Euros I know that´s pretty high for certain regions, but please keep in mind that I´m selling stuff for 100 Euros which would cost about 240 Euros bought new. So perhaps for the one or other this could be a good one. Thnx in advance and greetz! :)

Yes, either that, or: Just try to get the Core running first (with the LCD). Do NOT connect the SID yet, as that´s the part, which will not be easily bought again, you know. Check the wiring of your LCD! Especially check it for shorts (which you sometimes very hardly see)! When the core is running, putting the SID in place is a piece of cake. Also, do check if you did all the hardware changes for MIOS 1.8. There is a jumper that leads to the SID which probably needs to be resoldered. That´s not needed if you got your PCBs from SmashTV as he is keeping them updated all the time. Coolness. I really wish you luck and hope you didn´t fry the SID. *thumbspushing* Greetz!

Looks good I think... :P Yes, a wrongly connected LCD *can* cause such problems. Nearly anything connected wrongly can do that (just imagine a short somewhere). Does the sound come back when the LCD is disconnected?

So, das waren die letzten Teile. Noch hinzugekommen: DINs, DOUT, Printtaster und ein C64-Netzteil, das mir im Keller halb entgegengekommen ist (war auf nem Regal). Für diesen Thread sind das erstmal alle Teile, das wars. Kommt nix mehr dazu. Ich hab außerdem mal das Komplettangebot mit in das Angebot aufgenommen. Das hier immer hinzuschreiben ist evtl a weng blöd. ::) Also, hoffe euch sagen die Teile zu! :) Gruß pay.c

Also erstmal: Willkommen! ;D Klar ist: Auf ucapps.de kannst du dich schon mal sowas von durchwühlen, daß dir schwindlig wird. Das was du planst, hat v.a. was mit dem MBLC zu tun. Kannst dich mal einlesen (ucapps.de, wiki, Forum-Suchfunktion usw). Die Planung der Oberfläche (also Frontplatte) kann man erstmal *etwas* nach hinten stellen. Normalerweise baut man erstmal das Grundgerüst (oft ist es auch sinnig mit einem kleineren Setup anzufangen und das dann nach und nach aufzublasen) - sprich Core - das Herzstück plus einige Taster und Potis und evtl. ein paar Encodern. Später kann man dann Motorfader, LED-Kränze und mehr reinbringen. Von null auf MBLC zu bauen ist für einen Newbie grundsätzlich sehr hart! Noch eine kleine Frage (kam nicht richtig raus): Du hast geschrieben, du willst eine Mixer-Konsole bauen. Sprich: Du willst bspw. Cubase ansteuern, richtig? Ähnlich zu den Mackie oder Logic Controls, jo? Falls du hier Antworten zu analogen Schaltungen suchst (analoge Mixer - die tatsächlich Audiosignale mixen sollen) kannst du dir hier höchstens vereinzelt Rat holen, mehr ist aber nicht zu machen, da es sich hier um eine (fast) rein digitale Page handelt. Aber erstmal: Gut durch ucapps.de und wiki durchlesen! Da gibts auch einige Walkthroughs und HowTos - da kann man, wenn man will, Monate mit zubringen. Viele Späße!

Ok. Thats good. ;D Back to MidiOX: Do you get the typical MIDI-message at switching on? F0 00 ... 40 Does it repeat or is it stated only once when switched on? How much current is your stuff drawing? With backlight it should not be more than 300-400 mA. Without it should be under 100 mA. Both *very* approximately. If it is more you have some short somewhere or you have plugged in the LCD in a wrong way. What´s with voltage? Is it stable at +5 volts? Does it fluctuate?

Just to go sure (you didn´t mention it): Did you burn the bootstrap loader? Without it you won´t be able to upload MIOS. With MIOS there should be text displayed on the LCD.

I still don´t get it and so I got a little question spinning in my head: How do you want to realize following features: - changing backlight of the LCDs (just different LEDs?) - Drumpads (velocity?!?) The rest is more or less clear, but I´m cracking my head with this VERY interesting project (as I´m thinking about getting a new main keyboard for controlling). Thnx & greetz.

Errrr, I don´t know, but 500 mA are really ok for one LCD with backlight I think... :-[ I mean, the max backlight´s are using is normally 300 mA (really veryveryvery bright) - normally you land between 100 and 200 mA for a "normal" lighting. The rest of your stuff (Cores, DIN, AIN etc) won´t use more than about 50 to 100 mA (max!), so 9 Volt, 500 mA power supply is ok, I think (I used more than one 500 mA supply here for the MB stuff I built - worked out well up to now). If you won´t use LEDs (which consume a bit more) you should be just fine with your power supply. *Please correct me if I´m wrong* ???
