How can i connect this to the dout module? http://www.ebay.com/itm/250910900835?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

Thanks for the tips!

If I have the midibox sid stereo setup (2 sid chips) can I play drum och the LEAD at the same time? If so can I split the midikeyboard or Can I two midikeyboards?

I seen this interface on DE and on ebay http://www.dealextreme.com/p/usb-to-midi-cable-with-16-midi-input-output-channels-1-8-meter-11277 Has anyone got it working?

I reversed the polarity on the core module directly to the J2 pins. Where do I start to troubleshoot, what componets do you think are dead. I had every IC in pic and Optocoupler and also a display. What parts do you think is borken: resitors capacitors electrolytic capacitors PIC18F4685 Optocoupler 6N138 Diode TrimPot Crystal PCB? LCD The volatge was correct but polarity wrong. Now I got some strange chars on the display. http://imageshack.us/clip/my-videos/534/hqg.mp4/ Where do I start?

+5VDC drops to +1.7VDC with c64 when connecting core8 module
tob replied to tob's topic in Testing/Troubleshooting
Thanks for your help, now I know what was wrong. I had wrong polarity to J2 I putted the pic and opto in the sockets with wrong polarity! :cry: I was fooled by the left + on the picture http://mbhp.avishowtech.com/images/core/coreR4DETAILJ2.gif and I missed +/- on my multimeter, when I checked on the points. Very stupid!! Now when I connect the power with right polarity the background light of the display is lighten up. But the display is displayling some squares and then it disepears. Do you think the core8 is bricked when I switched the polarity? -
+5VDC drops to +1.7VDC with c64 when connecting core8 module
tob replied to tob's topic in Testing/Troubleshooting
I desolder the bridge reflector and now I got +5 on every pins ( I didn't see any instruction to desolder BR1?) When I put in the two IC and turn it on I now I get around 1.6V on the points, is this wrong? -
+5VDC drops to +1.7VDC with c64 when connecting core8 module
tob replied to tob's topic in Testing/Troubleshooting
It's the pcb and componets from smashtv. I can't see anything with my eyes, is it possible to measure shortingin some way? I have a multimeter with ohm,A F,V (DC & AC) and HZ plus a beeper. My bridge reflector (BR1) get's very hot is this normal? I get a beep when I put the probes on J2 but not on J1. -
I have build this PSU from the c64 brick http://www.ucapps.de/mbhp/mbhp_8xsid_c64_psu_optimized.pdf I get +14VDC and +5V. I have removed the 7805 regulator from core8 module and I have bridged leg 1 and 3. But when I connect the +5VDC to the core module J2 (no others module connected and no display and no IC i sockets) it drops to about 1.7VDC on all measurement points. IC1:MCLR(1) - IC1:Vss(12) = 1.7V IC1:Vdd(11) - IC1:Vss(12) = 1.7V IC1:Vdd(32) - IC1:Vss(31) = 1.7V IC2(8) - IC2:(5) = 1.7V What can be wrong?

Can I use MB-6582 control surface on a single core+sid module?
tob replied to tob's topic in MIDIbox SID
Ok, I bought the 1 x core8,2 x sid+1 x DINX4. My first thoughts was to build the minimal control surface and then I changed and wanted to go with the large control and now I'm more into the MB-6582 control surface. Maybe I go for the minimal anyway :frantics: -
SmashTV SID and C64 optimized PSU, dobule Voltage Regulator?
tob replied to tob's topic in MIDIbox SID
I missed that text on the connector 14VDC, I thought 7809 always delivered 9V. But now its 5+9V? Thanks anyway... -
I have a CORE8+2x SID modules can I use the MB-6582 control-surface? http://2.bp.blogspot.com/_5F4S32x8xtk/RkJbPDIVzgI/AAAAAAAAACQ/mRzuJ6Q-bQ8/s400/481496901_9bfa913cf4-1.jpg

I budling a core8 + sid module and LCD. I bouth everything from smashTV and going to use a C64 psu (brown). In the instructions i read to bridge the 7805 on the CORE module: http://www.ucapps.de/mbhp/mbhp_8xsid_c64_psu_optimized.pdf But my SID-module also contains a voltage regulator, should this also be bridged? http://www.midibox-shop.com/mbhp_SIDR3a.html

I give it a try, when i done with my core+2xsid modules. :laugh:

Is it possible do this on the midibox SID?
-
Thanks I try it, are they any difference on these chips? (I can't find any information about it) I read here on the forum that the volume and sound can separate from different rev of the chip.

I got two SID-chip but will they be good in a Midibox SID stereo setup? 1x 6581R4AR 2286 s 1x 6581 4383
