My FHX-8GT also doesnt work. I first connected wrongly the 10pin cable to the to esx out on the fh-2. hope that didnt fry my fhx-8gate. it now blinks after a few seconds red on all outs of the module. the fh-2 seems to be fine. eieieieieieiei no connection possible to the fhx-8gate. i still have pro...

i am wrapping my head around this thing right now. the glide circuit currently pulls down all my there oscillators in pitch. I narrowed it down to ic 21 ( in the schematics the pinout is switched as on the board) on leg 3 (schem.5)I do have without anything plugged into the jack cv in, 0 voltage but...

Done it was a wrong resi. juhuuu.now i can tune that little fella.

I am almost done everything works now. except I can't tune oscillator 1 as the scale trimpot doesn't do anything, ( on osc2 and 3 it works) and my oscillator 2 is quite far down in pitch what doesn't seem right even without calibration. have to check now R17 and r21 I guess for the scale on osc1. an...

For the 2N3392 the schematics says 'Selected' does that mean the Hfe?
also Is it necessary to Match the T23 and T24 ?

Hi, I wanted to try to use the FH-2 as a midi host today. So I connected my OP-1 via a USBmini to USBC cable on the USB-C port of the FH-2. Pyramid was connected via USB A port and USBmini. I setted everything and enabled midi forward from usb a to c and vice versa, but I wasn't able to get any conn...

i just found out all the legs of lm348 are differntly pinned out in the euro version than in the schematics. eieiei :woah: :woah: :woah: . this doesnt make it easier to debugg. @oldcrow it would be so helpful to have dedicated eurorack schematics or at leaste eagle images of the boards. Such i tight...

so two of the there are running now somehow but very quirky, the octave switch won't let me go higher than 250hz at 8'. I did use 1k tempcos with the right resi values, as those are suggested in the euro build. Osc 2 still is so low frequent that I can see the frequency on my scope only if I turn up...

I hope anyone reads this: I figured out that I have a very low oscillation on all three oscillators. the highest frequency I am able to generate is 8 hz. I guess I have a wrong resistor value somewhere in there or a wrong cap. anyone has a hint.? all the waves are there if I switch between all of th...

IMG_9540.JPG Hi everyone, I am currently building the euro version of the Crowminius. as the euro build seems to be quite similar to the normal one I will write here in the hope anyone answers. ( dedicated euro schematics and any kind of silkscreen documentation would be very helpful at this point!...

i was wondering if I can manage to somehow get an clock from the trigger out mode of the op-1 into th FH-2 via one of the cv inputs.(it is a trigger signal)
is it possible to "clock" the FH-2 externaly this way ?

thanks @agawell.

thonk only has the kit. i will write them and ask if they will sell me only the pcbs and the panel.

cheers.

hi there, anyone knows if its possible to buy a only Pcb panel kit somewhere?

hi @oldcrow,
im currently building the DIY version of the euro crowminius.
Does it make sense to glue TH tempcos to the LM3046 solder the legs to the SMD pads?
the panasonic smd tmepcos are dicontinued and I am not able to get them anywhere anymore.

cheers

here is may mouser basket: https://www.mouser.de/ProjectManager/ProjectDetail.aspx?AccessID=aa5801888c Edit: BE AWARE !!!! the toggles in my basket are wrong !!!!! the right ones are those: Mountain Switch 10TC410 15x Mountain Switch 10TC415 2x it contains everything except: LM1458D SMD PArts 9mm po...

getting the BOM together now. I will share the basket as soon as possible. it would be grate if anyone who built the modules could post a pic of the MA Host and MA Main boards built. as the components in the BOM sometimes do not fit quite on what i can see on the silkscreen. are the 67Y vertical adj...

I am wondering if anyone could share his/her Euro BOM from mouser or digikey.

would be really helpful

Hi I have an issue with my ambika build. im not able to flash the atmegas on the mobo and on the voicecards with the provided comandlines from the mui website. im using a usbtiny programmer. but first of all iam only able to set the fuses if i reorganise the commandline like this: avrdude -c usbtiny...

Hi i nearly finnished my ambika build (having all the ref voltages on the mobo), but none of the atmegas will let me flash normally when i use the code from the MUI website: avrdude -B 1 -V -p m644p -c usbtiny -P usb -U flash:w:ambika_controller.hex:i -U flash:w:ambika_controller_boot.hex:i -U lock:...

hi, i just finished the build, with all the necessary mods for rev.2 my filter frequency knob opens up the filter very late (3o'clock) i guess this is not normal and needs to be debugged. also the filter frequency knob somehow has an effect on the pitch of osc.2 when i listen to the tri an pulse b o...

Hi guys im planing to build a hexvca, but can't find information about the capacitors wich I should use. Also about the pots I don't have any information wich they should be. Do you maybe know anything?

Hi guys, has anyone built the hexvca? is there a BOM for mouser and is it possible to get a panel anywhere? would be super nice! ive started this BOM https://www.mouser.ch/ProjectManager/ProjectDetail.aspx?State=EDIT%20&ProjectGUID=98372e22-1266-42ee-8a19-96f76ab88cee ,from the manual from befaco.or...
