Davo Posted May 29, 2008 Report Share Posted May 29, 2008 Have you spent any money on producing this board yet? Given TK's announcement that the USART bug is fixed in new PIC18F4620 chips, I think it would be better to redesign this board to eliminate the IIC components.See http://www.midibox.org/forum/index.php/topic,10951.0.html for the announcement.

Pascal Posted May 29, 2008 Report Share Posted May 29, 2008 Have you spent any money on producing this board yet?

The EUSART BUG was fixed! The IIC Components bring 4 MIDI IN and MIDI OUT with it! Inkl. the MIDI IN and MIDI OUT of the Core!Ultra has designed the Board with the complete MIDI-Connection of the Core! What is the prob?When you eliminate the IIC-stuff you can solder a core ;-) Quote Link to comment Share on other sites More sharing options...
ultra Posted May 29, 2008 Author Report Share Posted May 29, 2008 if the purpose was to get around the eusart bug, there would be only one iic module. :) Quote Link to comment Share on other sites More sharing options...
Narwhal Posted May 30, 2008 Report Share Posted May 30, 2008 Are there traces missing from the layout image above? I was just looking at the power section and it looks like a few things are missing. Quote Link to comment Share on other sites More sharing options...
ultra Posted May 30, 2008 Author Report Share Posted May 30, 2008 no i've already tested it the power, everything is there. Quote Link to comment Share on other sites More sharing options...
Narwhal Posted May 30, 2008 Report Share Posted May 30, 2008 On my view of the layout that is shown above I don't see any trace going to the center pin of the voltage regulator (IC3) and there is no connection to the Bridge Rectifier - pin, it also looks like no connection to the - side of the Capacitor C5. I assume it is there somehow, as in the real board is different that this picture, or else you wouldn't have any power there. ??? I was just curious if you were aware of that or if somehow my eyes are failing me. ;D Quote Link to comment Share on other sites More sharing options...
ultra Posted May 30, 2008 Author Report Share Posted May 30, 2008 your eyes are fine, and to help them out even more i took this screenshot without the ground plane ;). Quote Link to comment Share on other sites More sharing options...

ultra Posted June 1, 2008 Author Report Share Posted June 1, 2008 i'll try to get it on the wiki this weekend. it's on the original thread but i have 220k resistors on there instead of 220 ohm. Quote Link to comment Share on other sites More sharing options...
Wilba Posted June 1, 2008 Report Share Posted June 1, 2008 Excuse me if I missed this in the discussions... did you leave the space left of C5 empty on purpose, so you can mount C5 flat against the PCB? ;D Quote Link to comment Share on other sites More sharing options...
ultra Posted June 1, 2008 Author Report Share Posted June 1, 2008 yeah i think that was sasha's idea. it's somewhere in the first thread. Quote Link to comment Share on other sites More sharing options...

stryd_one Posted June 6, 2008 Report Share Posted June 6, 2008 IBAN/SWIFT is the european standard for international bank transfers. In my experience it costs nothing for the receiver and costs me about $50 in transfer fees to send to them :/ Quote Link to comment Share on other sites More sharing options...
ilmenator Posted June 6, 2008 Report Share Posted June 6, 2008 IBAN/SWIFT is the european standard for international bank transfers. In my experience it costs nothing for the receiver and costs me about $50 in transfer fees to send to them :/The EU regulations say that a money transfer from your account to a foreign account using the IBAN/SWIFT codes must not cost more than a local money transfer within your country. As the latter is usually free of cost (at least in Germany), IBAN/SWIFT is VERY attractive and positive for us Europeans. It's a pia that your Australian bank charges you such ridiculous amounts of money. But I guess it would be the same for bank transfer to an "ordinary" overseas bank account (actually, IBAN/SWIFT is an ordinary bank account - just the ID codes have been internationalized to make the handling of inner-European transfers easier).Best regards, ilmenator Quote Link to comment Share on other sites More sharing options...
stryd_one Posted June 6, 2008 Report Share Posted June 6, 2008 Precisely :) Because we are not in the EU the rules do not apply ,but any other international transfer costs as much... Quote Link to comment Share on other sites More sharing options...
nILS Posted June 6, 2008 Report Share Posted June 6, 2008 To get back on topic - yes, Zossen, it will not be a problem to find someone to transfer the money via paypal for you after you sent them the money (you're in Germany, so there's lots of friendly 'boxers who'd be happy to help out. Me included) Quote Link to comment Share on other sites More sharing options...
