Get a 1.3mm drill and off you go. Do you already have the switches? Cause sometimes the pins aren't really quite as big as it says in the datasheet.

w00t! :frantics:

Wilba totally comes crying to me everytime someone doesn't go with the mb6582 option and actually does real DIY ;) Then I have to :console: and give him some :flowers: and he's good again! Seriously though - tipping hat good, making a new never-before seen case good, too!

Seems to work here: http://nic-nac-project.org/~rocket/midi/vmidibox/dev/

"Take off shirt while wiring this part" - yes, defo audiophile :thumbsup:

Thanks!

Love you, too :flowers:

Offsite doco disappears. Period. That's why it's a "requirement" to have doco for user projects here on site - attached to forum posts or on the WIKI. See Please Read Before Posting New Topics: What is a "User Project"?

Welcome aboard pj-27 :flowers: Please read the stickies. Especially Topic moved.

Yep, I've been using that as well :)

Welcome aboard Arkaduiz :flowers: That's a fairly "deep" question and answers sometimes take longer than 24 hours around here... Sadly we're not getting paid to do this ;) I think you might want to start by having a look at the mios32 repository at http://svnmios.midibox.org/listing.php?repname=svn.mios32&path=/&. That way you might get a rough overview over what is there, and how much is there. It would also be helpful for us to know what exactly you plan to do.

With some extra coding it is well possible, yes. I am werking on sth. similar but a bit more advanced for the core32 at the moment. A few ADSR EGs are certainly doable within the limits of the pic.

Müsst ich mal schauen, ich denke schon, dass ich einen gm5 + die kleene Platine (oder eben gleich eine anständige gm5x5x5) übrig hab.

Nice box, Altitude, good to have you back! :flowers:

War eine Schätzung, aber wie dem auch sei - was hast Du denn für ein Problem damit? Chip 4,50, PCB 3,00, dann noch ein paar Widerstände und anderer Kleinkram.

Yes.

Bester Tip: gm5. Mal hier im Forum suchen. Das vermutlich beste MIDI Interface wo gibt für unter 15eur ;)

I approve :flowers: Wilba doesn't like being hugged by guys though... :whistle:

Well... I see (among other things) 9 * 4 = 36 LEDs. With the default 220 Ohm resistors you're looking at roughly 15mA per LED. 36 * 15 = 540mA. To bring the total current consumption of the the LEDs to a reasonable level of say 72mA you'd need 1.5k resistors, which will dim the LEDs to the point of them barely being visible (if they work at all @ 2mA)...

That's what J2 is there for (among other things). It's generally advised to remove the voltage regularot and bridge pins 1 and 3 (in and out) if you do that. Then again - don't do it. USB is really not meant to power stuff with a current draw >100mA. The thing with the Y-cables is that you need to connect it to two different ports on the PC side. Not just two usb sockets, but two individual ports. The USB ports on a lot of mainboards are all connected to a hub internally so they may just be the same port - with a total of ~100mA to be used.

The 1.4V you got are easily explained - You're feeding 5V DC into the bridge rectifier of the core module - diodes cause a voltage drop - then the voltage <5V goes into the 7805 which needs ~7-10V to work properly. What you are doing can't work. J2 can be used to supply power to a core module (if you know the voltage is constantly really nice 5V, polarity is right etc.) that's really all that bad at all - if you know what you're doing (the "no J2" comment makes me kinda doubt that a little bit :whistle: ). But I do agree that powering the core via J2 from USB power from a gm5 is bad juju :) With a gm5 and a core + some peripheral (there's going to be more than just the core, right?) you'll easily get over the max. current a USB port can deliver. And that can do anything from simply not work to blow up your maiboard. -

Hehe, sometimes it helps talking about a problem... :thumbsup:

hehe, whoopsie :) Typo DINx1/4 -> DOUTx1/4, fixed original post, thx lyle!
