we're happy to offer full kits for both the black and white magpie panel versions-- all the parts you need, and the Tides ARM flashed with the latest firmware already!

Enjoy, and thanks to electric mist, magpie, altitude909 and jakplugg for all the work on this

hello all,

just got done with a build of uTides from a Synthcube kit and I'm completely baffled. i plugged it in and it powered on just fine but all the knobs aside from the main frequency knob do not seem to be functioning properly. i assumed this is because i need to calibrate it so i attempted to initiate the calibration procedure by long-pressing the mode button but nothing happens (it just changes modes as though i short-pressed the button instead). there is zero documentation available on the Synthcube site relating to the specific version/firmware i'm working with here and i cannot find any documentation anywhere regarding what this could indicate. i have read up on all three firmware versions (official, Parasites and Sheep) and none seem to reference any of the things i'm experiencing. the only thing the module has done properly is enter firmware update mode by holding the mode button at startup. i was able to successfully push v1.1 standard Tides firmware to it but it still does not function as expected. it is possible i have built it wrong as there are also no detailed build guides readily available anywhere and i'm experienced with builds but far from a pro, but a thorough inspection hasn't revealed anything in need of servicing and the spotty functionality and sparsity of documentation has me at my wit's end. anyone have any ideas on what might be wrong or how i can enter calibration mode?

EDIT: the level input doesn't seem to be working. this would likely explain its inability to enter calibration mode. Synthcube has recommended I reflow all the potentiometer and jack joints.

EDIT 2: after reflowing all solder joints for potentiometers and jacks i'm still having the same issues. i did a little more research and reading and some close comparison with the Eagle files and i've noticed a few things. first: the board i have is labeled Swirls/Lamb v1.1 but is actually a v1.2 board. second, there does not seem to be any facing information on the board or in Eagle for IC8. not sure how i missed it while working on the board but i suppose mistakes are inevitable. anyways, about to try to pop out the IC and swap its facing to see if that helps.

EDIT 3: nope. won't power up now so i must've had it right to begin with. totally out of ideas here and my lack of electronics knowledge means it will likely be a long road to be able to navigate a schematic well enough to know what proper voltages should be at various points in the chain. any advice at all is totally welcome but barring that i think i'll just need to get another kit and try again, then revisit this one to see if i can repair it with things i've learned from the second go round.

Anyone have any issues with the LP/fold knob. Mine only seems to make any difference in the last 10% of its clockwise travel. The knob does not seems to take the module into LP mode at all, but has a wave shaping type effect between 4 and 5 o'clock. I've replaced the pot, triple checked solder joints, measured all resistors. Only think I changed was 2 incorrectly placed caps, C15 and C16. I had the caps rotated 90 degrees and gapping the wrong pads. Would the error with the caps have possibly harmed the DAC?

I've tried multiple versions of the firmware, updating through the .WAV method.

Anything else I can try here?

hey TinyTrucks, i actually had the same problem with all three trimpots in that row. only the last little bit of the knob seemed to do anything at all. unfortunately i screwed up the pads under one side of my microprocessor so it's out of comission but i ordered a second unit and will be getting to work on it in the next few days. i'll let you know if i have the same issue again after building. would love to get to the bottom of this.

finishined mine, my first SMD project as well. burning the bootloader and firmware with a cheap USB ST-link went ok, i think. finishing installing the pots (NO ONE in US has any linear 10k trimmers in stock, had to order from the UK) and will post photos of the finished project when i get a knob for it. (forgot to order that! DOH!)

speaking of firmwares. have you tried loading Sheep on yours and check for functionality?
vespine
so i have the synth cube kit with the v1.1 board


https://github.com/ElectricMist/Swirls

so the bom has R1, R11, R47, R48, R49, R57, R58
are supposed to be 10K Ohm

and the kit comes with that in the pack but there is no R1 or R11 on the board (confirmed against the brd file) and i do not see this discrepancy mentioned anywhere..
I'm continuing with the rest of the build.
vespine
i was missing some more parts from the kit, namely the correct size of tl072, i've got that sorted now but the module isn't working quite right.

both buttons cycle green > off > red > off > green

the modes seem to work ok, i actually though it wasn't working until I realised "yellow" mode, the one that appears off on my unit, is the cycling mode and the other modes require a trigger. I've done some testing now and it all seems to be working right, but, for some reason, yellow doesn't display, which has me really stumped since yellow is just red and green together isn't it? I have built a rings with a very similar bi color led configuration...
vespine
just realised there's 2 different versions of tides, i've been looking at the new one....
