  1. Hi Justin, I build mine with a simple rectangular box, but .. I shortly started to notice, that some angeled sidepanels suit me better .. much easier to handle that way .. but it all depends on where you install your MBseq ..
  2. Perfect ... new Controllerboard for the Sequencer .. and I take the old one for other projects ;)
  3. @Hawkeye .. now this is good news :D
  4. @FantomXR ... 26 Weeks delivery .. autsch ...
  5. STM32F407G Mouser => availability .. ZERO, since some months Didigey => availability .. ZERO .. since some months Conrad .. ZERO WattenRott .. ZERO I hope we still find some or the next generation of the boards soon ..
  6. Now this iiiiis cool, @TAG do you have more buildocs or some of the code you used for this project?
  7. @bemerritt .... nice idea to check the board too ... I will do it this weekend (the big fun of debugging ) ... new AOUT_NG Board ordered yesterday, now I still need that nice little TLV .. again .... :D Core schematics of the STM32F4 Core say, that J19 is connected to IC1 ( 74HCT541 legs 15-18) and PB4 of the STM32F4Discovery (which took quit a while to find) http://www.ucapps.de/mbhp/mbhp_core_stm32f4.pdf
  8. Do you use a Linedriver or connect directly to the Core? If you use a Linedriver, try connecting the J19 of the receiver to J19 of the board OR connect directly from the board J19 to J1 of the AOUT_NG (with the special cable)
  9. O.k., a little update on the AOUT_CV. I desoldered the TLV today, reconnected the board and did some measuring on the SMDpads to see if there are other errors. All OUT's except OUTB and OUTG have -13.78 Volts ???? OUTB and OUTG have 0.13Volts ... J1 Pin5 (SC) has connections to pads 1-2 and 3 of the SMD-field. I know shit can happen and I know my soldering is not always perfect, but if there was no production-fault on my AOUT_NG board (which can alway happen) there is one now ..... So .. restarting at zero ... buying a new AOUT_NG board and all new components .... savest way
  10. You could make a midi-dump from your electribe and then import it to your Midibox. http://www.ucapps.de/midibox_seq_manual_in.html
  11. You will need a pic-burner .... there are some, not that expensive via amazon. I got a wingoneer and it worked just fine.
  12. I connected the AOUT via the Linedriver to see what happens Results from the testaoutpin via mios terminal J1 of AOUT_NG between Pin 1 and Pin 2 I have 4.8 Volt testaoutpin cs 0 => pin 3 => 0,13 V testaoutpin cs 1 => pin 3 => 3,67 V testaoutpin si 0 => pin 4 => 0,13 V testaoutpin si 1 => pin 4 => 3,66 V testaoutpin sc 0 => pin 5 => 0,13 V testaoutpin sc 1 => pin 5 => 3,64 V so all seems like it should be BUT ... PIN 13 (OUTB) of the TLV5630 gives 2,16V permanently .... so ... solderissue there ... somewhere ... or TLV damaged like latigid_on said ..... so, luckily I have to place another mouser order next days ... wheeeee ....
  13. JAOUT is connected to J1 I removed the ICs, but with or without ... same results ...
  14. Receiver PCB JAOUT to AOUT_NG J direct 1:1 soldered .... Pin1 and Pin measure correct 5V on J1 I also tested without Printercable and connected J19 of the STM32F4 board directly to J19 of the receiverboard .... JAOUT of receiver_board and J1_AOUT_NG stay connected ( I didn't want to desolder everything to test it with the special-cable you describe in the AOUT-Wiki)
