Mainly only the chassis. Take any ground connection (e.g. just solder a wire under the core on some ground - the big stuff is always the ground). Take care of isolating the power supply good from the chassis (could bring in some short). The other plugs don´t need to be grounded anyhow (MIDI conns, Banksticks and so on). I think thats it... :)

Hmm, hast wahrscheinlich recht. Durch das ganze UCApps Zeuch sind sowieso schon alle 5V (bzw. halt 9V) Netzteile in Gebrauch, irgendwo werd ich sicher noch 12V-ler rumhängen haben.

*BIG* Thnx for the compliment! (btw... ... nope, no trade ;D ) Will try that laquer technique with MBSeq (won´t the photo laquer more be like violette than black?)! Thnx! Now that AVU RX starts to make sense... ;)

Me, too, you can believe me that! The crystal should be OK (the PIC´s coming up). Anyhow: You did isolate it, did you? It´s touching no blank areas, right? What´s weird: If you have a short, the current should go wide over 100 mA, if you have no short you should be at about 30-50 mA. ??? Conclusion: Something in between. ;) Check all your soldering, check all your parts (stupid, I know - but in the moment I have no better solution). Is the other IC put in correctly? (I did manage to put it in the false way two times... stupid me... ::) ) Clean the PCB roughly (perhaps it´s some veeery small short), meaning just wipe over it with some acetone or similar. Can´t give you more than that for now, sorry. :P Good luck anyhow...

12 V für die HG? Hmpf... :P Irgendne Idee wie man aus 5V 12V macht? Diese DC/DC Converter sind so sch***teuer (5V auf 12V/100mA (!) 8.80 bei Reichelt). Gibts da nich so Spannungsverdoppler? (10V könnten ja auch schon ausreichen) Notfalls halt 12V Netzteil direkt ans LCD und für die Core auf 5V runter (der arme 7805er ...).

Perhaps try following: Deconnect the backlight (it´s very power-consuming) and all modules (DIN/DOUT) and measure the current the core takes up ( deconnect either pin of the supply and between the Pin and the supply cable measure the current). It should certainly be not above 100 mA (only with the core and no LEDs/backlight). App. 30-50 mA. If it´s higher you got some short on your core (it´s often the "Quarz" (english??) under the PIC).

Timing!!! ;D Wollt grad noch 2 2x40er bei Reichelt bestellen. Thnx! HD44780 ist ja kompatibel zu unserem Zeug, oder? /modify: So, schon zwei bestellt. Weiß nicht, ob er noch welche hat... ::)

Dammit that *does* look professional. The photo looks like it has made in some photostudio! Same question by me: How the heck did you make this b/w frontpanel??

Displaytech ruuulz! ;D Just wish Reichelt would offer them with more background colors (I LOVE those black background, red fonts LCDs).

Really cool design, definitely has to come into the Midibox of the week thread! Should be no prob to bring two cores into that housing, or? (the costs of Midimerger are really low)

My oh my oh my. Looks & sounds just great (you could bring the first example out on record if you tweak it a little more - sounds awesome up to now!!). Does that mean that the Control Surface will keep like that now? (Then I would start designing it (I´ll try a 2HE design - perhaps that´s possible) and to get the first parts) Awesome, just really do love it! In my opinion, this is the best app of UCApps up to now!!! :D

The whole MB works on 5V, so all Caps should be at about 16V or higher (16V is the lowest you can get, I think). It doesn´t matter if you go higher. For the W's: That depends a little bit, but normally you can say that 0,25 W is absolutely enough for all parts! I didn´t get your last question quite well, but if I understood you this is the answer: As far as I know (or TK just built something new in there again! ;) ) you are not able to connect any pots to a MB64E, you can only use Encoders. So no AIN. As far as *I* know... Greetz!

Cool, also: Der Typ hat zugestimmt. Geb ich hier mal seine Emailaddi an: familygate@tiscali.de Wenn wer Interesse an obigen Angebot hat, einfach unter der angegebenen Addi melden. TK: Irgendwie abspeichern, oder ist dir datt Angebot nich gut genug? ;) Gruß pay.c PS: Nach dem Erfolg, werd ich mal versuchen, Reichelt zu überreden, andere Potis, passende Knöpfe und Encoder mit ins Prog zu nehmen, ;D

da-da-da-daaaaaaaammm ... da-da-da-daaaaaaaaammm ... ;D (not quite sure if this really is Vivaldi...)

Welcome!! :D Yeah, should be that (Does the 7805 on the core get hot?). Measure the resistance between GND and 5V on your DIN to go sure.

Yepp, just get the schematics of the LTC and only use one of those 74HC00s. Did that, too, no prob to build that up on a breadboard.

Yepp, it will stop any further oxidation. Greetz

That´s correct. But also the flux is there to take away *small* amounts of oxide within the soldering process (it gets the oxid away when it´s getting hot). That helps !alot! doing nice soldering.

Hab mal folgendes Angebot an Land gezogen: Geht um die ALPS Motorfader: 1 bis 9 Stck = 24,50€ zzgl. Versandkosten. Dieser Preis ist sehr knapp kalkuliert. 10 bis 49 Stck = 22,10€ frei Haus (!!) Ich glaub, der Typ versendet allerdings nur innerhalb von Deutschland, kann evtl nochmal nachhaken. Wenn Interesse besteht, mal Bescheid geben (mit Menge), dann frag ich Ihn mal, obs in Ordnung geht, wenn ich seine Email weitergeb. Gruß pay.c!

I have to say that I have only made good experiences with Behringer up to now (I have a mixer from Behringer and my Boxes are from those guys, too - they really do rock!). Really. And what you also have to think about: For the same (or a little more even) money you get that from other guys: Doepfer Drehbank (64 Pots - 2x7seg display) 333 Euros @ Thomann. So it is a really good price, I think. And: YEPP! MBHP still does RUUUULE!! (Especially if you look at the features of our stuff and compare it to commercial stuff: MB64 - Doepfer Drehbank, MBSeq - Doepfer StepSeq, not to forget: All those SID (all mono ones!) stuff out there). ;D

:o *Impressing price*! From Behringer: " The BCF2000 is an innovative, hands-on control surface with ultra-precise 100-mm motorized faders for the ultimate control of virtual mixers..." Motorized pots, encoders and (nearly) all LC stuff! How the heck did they get *that* price??? You even hardly could get that price by DIYing!

Hopefully we won´t get any new members the next time... ;D (*ironically!!*) ;D

For 24 Volts: Nope, not without a DC/DC Converter or something like that. TK got the max out (5V + 9V = 14V). And those things (for the needed Power) are dammit expensive... For that ground to ground problem: Could be solved by using a 1:1 transformer (its 9V *AC*). Just put it in between the PSU 9V AC and the Nanoverb. Makes a galvanic disconnection - no shorts possible anymore! Only prob: Could bring in a big amount of hum, if not properly covered... :P Using one PSU for two seperated things is always kinda prob.... :-/ Anyhow: Greetz ;D

TK: Good question, never tried out that! Anyhow, I´ll try the new MIOS. Sounds very likely to be some problem with my setup, too! I also had hanging notes at the beginning! And this also explains why I had to ground-cover the Master-Slave Midi Lines to get those working. I´ll try it (in some weeks - still in the middle of my tests). Besides: Same thing like doc said by me: No need for any excuses. In fact I´m kinda happy if a bug is found in MIOS from time to time, so we all can be sure, you´re still a human being. ;) And we are all DIYers, so even finding out those bugs makes fun (I would be sooo dammit hooray if that bugfix also works out well for me)! 8) Greetz!

Oxidation: If doc´s recoms don´t help (which means it´s a really thick oxid cover), just take a sandpaper and lightly go over the PCB a bit. Then Lötlack again. Worked out well for me.
