If the LEDs go out when the ouput jack is in then maybe you have wired the output jack up wrong.

It is a quirky module itâs hard to tack down a specific wave when you need it but has a way of spitting out random magic you couldnât just think upâŚIâm thinking about getting a second or maybe making a more simple, utility-esque LFO for basic things and let the LMNC/Electric Druid LFO do the heavy lifting

sounds like Sam . that makes it a Kosmo âŚ

@fluxpavilion that multiplier will be your best friend with the LFO on the filter. On time synced wobbles =]

i havnt even got it in a case and i already love each module
there is nothing else quite like them

I think thats part of the appeal, they look so god dam coolâŚ
I keep intending to just build a âLIGHTâ panel with pulsing lights between cutoutsâŚ

I just got my PCB and am starting to order my components. Do the jack sockets need to stereo or Mono? The link in the material list is a stereo post, TRS, but the wiring only shows 2 connections.
Any help would be greatly appreciated!

hey Jon! use mono! I just suggest stereo as they tend to be cheaper weirdly enough (big jack versions anyway)

They only need to be mono, but depending on the module specified jacks may be stereo to fit in the board. The VCLFO can use any old mono jacks.

yeah@!@!! its been on my to do list to do a kosmo K as a blank with a cv input for red blue and green could be snazzy

Or mono ones might even be unavailable. Last time I looked at Tayda I think all the mono 1/4" jacks were out of stock, and I donât think any of them fit the footprints on the boards that use board mount jacks anyway. I just get the stereo ones and on the odd occasions I need a stereo jack, hey look, got one right here!

I have some addressable LED tape on back order⌠I love a bit of bling so a purely Aesthetic light module is in orderâŚ
Also have an idea for Kazmo, a modular i2c display girlfriend for Kozmo

TRS (tip, ring, sleeve)
are the most common manufactured from what i have found. there is no point in searching for pure âmonoâ = TS as they will be just as expensive or more as they are hardly used.

Got a VCLFO here - my buddy built it -
I went over it and re-flowed, checked for anything loose, swapped out the TL074 (it seemed like it was getting a tad warm) and fiddled around with the preset pot a little.
So here is what it is doing -
Outputs just fine it seems - but the LEDâs do nothing, well, i should say just one stays solid and never stops.
I adjusted the preset pot counter clockwise and the Positive LED shut off and the Negative LED came on.
I tried to get em right smack in the middle and they both shut offâŚ
Anyone has even the slightest idea of what it could be?
I thought this one was kinda dummy proof, but i guess not lol.

Keep turning the trim pot! I had the same issue a few weeks ago! Make sure you put the wave distort in the middle and then try the whole range of the trim pot⌠there seem to be multiple spots where it looks like it almost rightâŚ

lol wow.
yeah, thatâs all it was - just kept turning it the other way and all of a sudden the LEDâs sprang to life just like my VCLFO.
I was so perplexed, I donât remember mine being that difficult to find the âspotâ lol

Interesting. I am having similar issues. I can get one led to blink or the other, but not both!
Iâll try more trim pot fiddling.

just keep turning it for like a few min 1 way and do fiddle with the knobs a bit so you find a setting that is actually generating positive and negative lol
otherwise you can become even more stumped like I did at one point lolol

the easiest way to calibrate it is to turn the level knob (one just above the + outputs all the way to zero, then wire any output from the lfo to something like an oscillator cv input. then fiddle with the preset trim pot on the back of the lfo. keep twisting and unplug the oscillator and plug it back in, when your at a point where you cant tell any pitch change in the oscillator if the wire is plugged into the lfo or not, that means the centre of the LFO is at 0v. so then when you turn up the lfo level both LEDâs should be doing what they are meant to

Hay! It works! At least I think. Premium beeps and boops abound.
Also! If it is working, this means that you can sub out a 2n2222 for the bc547 - BUT you have to put it in backwards.
