We will also have .bin files available very soon, but I would encourage you to try to get things built locally so that you can tweak/make changes/add and remove effects to the unit
@keyth72 I am having a lot of fun with the mesa II NAM model. It sounds a little bit better and easier to dial in than my wampler triple wreck pedal I think!
This module has accomplished so much of what I was interested in that brought me to the daisy and this project so thanks for the work on it!
I think the 3 band EQ really helps bring it home, so I am super happy with that!
@xconverge Awesome! Glad you are enjoying it, most credit goes to the Nam developers and the RTNeural dev, I just shoved it on the Daisy seed .
Speaking of the Nam module, I was thinking it might benefit from using your recent parameter scaling additions, I wonder if using exponential scaling on gain would give it a more “amp-like” feel when you crank it up.
Hello everyone, have built a terrarium but struggling with the noise issue. Guessing I’ll be adding a 22kHz Low pass filter as was suggested by someone else on another thread. (If anyone has a link to how I should do that, I’d be gratefull, I’m not very experienced in electronics)
But I was wondering another thing. Is the 22kHz Low pass integrated in the pcb’s on your github @kshep ?
Might give your pedal a go. Midi and an OLED seem very tempting…
I’d use a filter a lot lower than 22Khz.
I found the link to the post again. @keyth72 says in this post that it is working: Daisy Seed + Terrarium Rev5 -> Rev7 terrible SNR - #5 by keyth72
Yes the latest PCB rev for the kshep project has this integrated
Also wanted to point out that the kshep software side of the project supports the terrarium as well in a limited fashion (due to no screen or encoder) if you want to try it out!
Thanks for the confirmation! Guess that the files on Github are all the latest versions?
Exciting! Guess I’ll be ordering five of those then. Anyone within Europe who wants to split an order? Five seems more than enough to start.
Might try the firmware on Github but I have some gen~ patches that are waiting to be loaded on a pedal like this.
Finished my first build of the 125b oled pedal! Went by the build guide in the readme, and used the included gerbers. I got parts to build 4 of them.
The build went fairly smooth, the spacers I got for the oled screen didn’t fit the holes in the pcb/screen, so I improvised by gorilla gluing them in place.
My main issue during that build was that the thread length on the alpha pots really need to be longer, I wasn’t able to use the washers because there just wasn’t enough thread for the nut to grab on to, after the thickness of the enclosure. I didn’t see another alpha pot option through Tayda, but I wonder if there’s a version of those pots with just a little more thread length? Also, there is a little nub on the top that causes them to be at a slight slant after you tighten the bolt down, maybe I can file that nub down or something.
Update: filing down the nub on the top of the pot allowed enough room to use the washers and level out the pot shaft. Win!
That’s just my nit-picky comments, it functions great! And the low pass filters seem to take care of the noise I was hearing on the original version @kshep sent me, once it switched to the rev 7 seed.
Those nubs snap off with very little force with a pair of needle nose pliers, I have always snapped them off on every pedal I have ever built where they were supported by the PCB. I have never drilled a clearance hole for them (which is what its for to prevent the pot from potentially spinning…if you are a gorilla).
Does anyone have an idea where I can get information on what pot/encoder/led is connected to which pin for this pcb? Is it the same as on the terrarium? (because i just made a json file of that one after trial and error, could do the same for this pcb, but maybe someone here knows?)
Also: is the Oled on the i2c pins or on other pins? Not really sure that I can address the i2c pins via gen~/Oopsy…
The issue you mentioned relation to the pot heights is a pain. I was never able to find a combination of pots and encoders that worked better together. There is always a height differential between the pots and encoders unfortunately. They make pots with longer shafts, but the threads are still the same height, not longer. From your picture, it looks like you are using the wrong encoder though. I think yours is the one with the 15mm shaft, I’ve had more luck using the 20mm encoder shaft when using the alpha pots. FWIW, I also usually don’t use the standoffs with the screen. Usually, I find the solder on the pins sufficient enough to support it.
Glad you got them built! Excited to see what else you do with them!
@dhoinjo The pins for the 125b pedal are not the same as the terrarium. The pots are connected to pins D15-D20, the foot switches on D5,6, the encoder on D2,3,4, the leds on D22, 23, midi on D29,30, display is SPI not I2C. I made a json file for plug data at some point, if you ping me on the electro smith discord I’m happy to share it with you.
Ah great to hear! It won’t be difficult adapting the maxmsp json from the pluggdata json. Only minor differences.
I will once I have everything in. (Would order from you but I’m afraid import fees will be a bit steep)
Do all boards have the 22kHz Low pass filter built in? Because I’m still looking at how to address the OLED from within gen~. If it’s not possible I might go for the screenless version first.
Thanks for all the clear docs on Github by the way. They’re a great help! Will report back when I’ve made some progress.
@kshep good catch from just looking at the picture! Yeah I ordered the wrong encoders, I noticed before I put the pedal together but made it work for this one, for the remaining three I ordered the correct height encoder. I think I used the Mouser link from my GuitarML fork, which is the old version. Since I moved all my software modules to the main project repo, I think I’ll delete my fork to avoid confusion for anyone else.
FWIW I got my encoder from tayda for my 125b build and don’t remember having any crazy issues with it during the build https://www.taydaelectronics.com/rotary-encoder-11mm-20-detents-d-shaft-with-switch-vertical.html
@dhoinjo Only the 125B board has the built in 22khz low pass filter. I never got around to updating the 1590b screen less version to have it.
Ok thanks. Might go for the screenless version and do the mod myself. Where does the filter go? On the input Jack or the output Jack?
No, it’s directly off of the Daisy Seed audio output pins before the buffer that drives the output jack. Like this:
Just sent you a message over there, thanks!
