  1. Out-of-stock parts for midiphy BOM tool

    hi, Reichelt runs also, it can be used here in France no problem and cheaper than Digikey for small orders. for the 560 ohm resistor i replaced the 1206 with a standing small form factor THT. 
  2. midiphy gates/clocks module

    yes i like 1206, just received a set from the land in the middle. unfortunately some of the boxes had opened in transfer so at some point i have to put the crumb puzzle back together (unless i got lucky and the required values are in the properly closed boxes)...
  3. midiphy gates/clocks module

    awesome! i was just about to mount an AOUT_NG to a eurorack panel... but if this is based on the same schematic as the AOUT_NG, i might save the components and wait with building for this more compact solution :-)
  4. Troubleshooting midiphy SEQ v4+

    JPA0, this did the trick! thank you once again!  also had to delete the previous MIOS32 entry in macOS Audio Midi Setup to bring it back correctly ... MIDI isn't really as smooth under Mac as Peter suggests... time to sleep, those were enough careless mistakes for today... tomorrow i have to debug a real CAN buss system at work ...
  5. Troubleshooting midiphy SEQ v4+

    ok ... so i desoldered all the Matias (ripping off most of the pads on top ...), clipped everything on the Enc-Plate even more and also the resistor networks and soldered back in the Matias ... it works now :-) (resoldering the Matias is not recommended - one of the more stupid mistakes i've made. it would probably be an idea to provide a kapton isolation sheet in the shop to prevent this?) i loaded seq v4+ and started testing a bit. this went fine until i tried to go back to midibox ng where the flashing failed halfway and i got stuck in bootloader mode. now when i powercycle the core is not detected any longer in a MIDI scan and does not show up in the USB device tree (i'm on macOS)... the green led on the back of the Core still flashes slowly when i power the Core but i don't get the bootloader message on the screen. maybe i'm stuck in some kind of low level boot mode? any suggestions? thank you!
  6. Troubleshooting midiphy SEQ v4+

    yes i had everything working before i soldered the mathias, also before i installed the encoder caps. but i probably shouldn't have tested DURING pushing on the encoder caps ... i did cut the encoder legs but there seem to be a few possible other shorts, in particular between the resistor networks and the thru-board headers... i guess i'm going to have to borrow my neighbours fancy desoldering station :-/
  7. Troubleshooting midiphy SEQ v4+

    Hi, i have a problem on the LE-MEC LH after pushing on the left most encoder cap the leftmost row of buttons doesn't work any longer: leftmost encoder click, leftmost upper and lower DIN and MEC don't work any longer. leftmost encoder turning works and the LEDs are also ok. i suspect something got shorted as i pushed on the cap. any hints at which components i should look at (and if i can fix it without desoldering all the Matias switches ...) Thanks!

    that's actually a good point ... i might indeed be interested in peripherals like 8x AOUT_NG so i think i'll keep them for now ;-)  
  9. Out-of-stock parts for midiphy BOM tool

    ah! hmm.... not sure what happened ... but somehow Mouser put the 25 pack No. 595-MC3486NE4 in my cart after I imported the BOM from the midiphy page and I didn't question it sufficiently. or maybe that was the previous BOM part No. before you changed it?? anyways, not a biggy, my purchasing skills are a bit rusty after some break from DIY  
  10. Out-of-stock parts for midiphy BOM tool

    hi all, should maybe be in market but since it's for SEQ V4+ i try here... i bought the Mouser mandatory min. amount of 25 RS-242 interfaces (MC3486N) and have 23 surplus now, if somebody wants to trade for something or buy at very good price just for you my friends  
  11. Out-of-stock parts for midiphy BOM tool

    Hi, The Hirose connectors MDF7-10S-2.54DSA(55) are out of stock at Mouser with a 16 week lead time. i found some at Digikey but maybe there is another store with more favorable delivery conditions? (btw. sorry i didn't see this thread before i guess i should have posted my Tayda stuff better here) Cheers
  12. midiphy SEQ v4+

    Hi Peter, I'm happy I can contribute a little bit back after lurking all those years :-) Concerning the LED, i've marked it in red now which means parts where people should be careful in replacing. And I checked my previously bought MIDI ports again from both Tayda and Mouser and it's true Tayda seems much cheaper and doesn't have a nice metal casing. I marked those, too. Another thing I noticed, not related to Tayda, is that the MEC switches are out of stock at Mouser now. too many SEQ V4+ builders? :-) I did find some at RS so might order from there (unless someone has a huge stock and wants to make a nice offer), but i'll eventually add more columns for other vendors Cheers, Gerhard
  13. midiphy SEQ v4+

    Hi Smithy, just saw your post. i was the user requesting (and now providing :-) ) the Tayda BOM. it will be only a partial BOM since they only carry quite basic parts. for now the BOM lives on Google sheets: in principle i agreed with Hawkeye and Andy to share only once confirmed, but I've decided to go through my stock first (including scavenging some unfinished midibox builds which are now on hold ;-) ) and use parts I already have instead of blindly re-ordering everything from Tayda. so i will only order what I can't find at home, but maybe someone else finds this list useful in the meantime.  most of the parts i have are actually from Tayda already. i can make this editable to anyone interested and you are free to copy and host elsewhere if Google is not the preferred host. Cheers, Gerhard
  14. WTB: DINX4 and DOUTX4

    Great! Germany (need to update my profile ...) - i send you a PM!
  15. WTB: DINX4 and DOUTX4

    hi, if anybody has some spare DINX4 and DOUTX4 boards (R5): WTB - i'll take up to 4 of each if available, but singles help me already thanks
