Mystic Circuits VERT (source files now available)

Post by windspirit » Mon Feb 01, 2016 2:55 pm

***UPDATE***

Vert kits have been sold out for awhile but this post will hopefully help folks build the kits that have been sitting in a drawer.

Also the source files have finally been cleaned up to my liking and are now being shared on github in keeping with the Turing machine open source license. Updated the github to have all of the info that was on the old DIY site. If anything still has a broken link or missing info please get in touch and I will give an update.

Note that the Vert also uses a "Universal Front Plate" PCB for the front panel PCB. Turns out that the front plate wasn't as universal as I hoped so I probably will not build new modules based on it. Feel free to do whatever you like with it.

***********************************************

Hey folks, I have the Vert's build documentation online now. Seemed like a good time to start the build thread. I'll set up another one for the Switches expander once I have that build doc up. Should be a lot shorter since I spent a lot of time making the SMD soldering instructions on the Vert as clear as possible. Please read the full build doc carefully before attempting to build the Vert even if you consider yourself an experienced builder. There are a couple of steps which, if done out of order, will make your build much more difficult.

Also I mention this several times in the build docs and on the website but this is an INTERMEDIATE project. I would absolutely suggest that you not take this on as your first build, but rather that you have at least 5 working projects under your belt before this.

Here is a link to the docs:



Here is a link to the mouser BOM:

For those that don't know the Vert is an 8-bit analog to digital converter with an internal voltage controlled clock and a turing machine expansion header. It can run at audio or LFO rate. Here is a video showing what the Vert can do.

Hey, just read through your build doc. Looks great! Still waiting for my PCBs and some of the parts to arrive, but I will let you and everyone else here know how my build goes, once everything is here ;)

Could you elaborate on the chaotic mode that you left out of the production modules?

Thanks! Please let me know if there is anything that can be improved or expressed more clearly. It is only the 2nd build doc that i have ever written but it certainly wont be the last so I would like to only get better :D.

So basically in your typical 555 schematic there is supposed to be a capacitor between the voltage control pin and ground. I realized that by shorting the pin directly to ground I got some wacky results but it worked in tandem with the FM attenuator so I didn't want to have this as a permanent feature. Basically the more I attenuate the input the more the VC pin is connected to ground and the more chaos is exhibited. However there was only one 555 variant that I found this worked with and when I was in 'clean mode' (aka FM attenuator only acts as an attenuator, not as the chaos control) I would get double-triggers from this particular chip variant. So that made it really tough to use with sequencers and such as it would advance 2 steps every time a gat went active.

So I swapped it out for a more reasonable 555 variant. I'm having trouble remembering the exact 555 variant that chaos mode worked well with, I think that it was the TLC555. I know I have some in my test drawer so I will dig it up and get back to you. Anyways I am hoping to build this particular quirk into its own module, a little "stupid sound maker".

The link below should have a short audio demo of what chaos mode sounds like:

Full component kits are now available, only all white LEDs at the moment, please check the site for details.

Also notice that I use recycled mouser packaging to sort the parts. You can read more on this here: http://www.mysticcircuits.com/2016/02/b ... -kits.html

that's going on my to buy list :tu:
edit:
just read the quick start hmm that expansion header is going to be super useful , will wire straight in to my version of voltages.
It probably wont happen today but if it does it definitely wont go smoothly.

I have the same vision ! why waste what could be re-used ?

i really like the packaging as well, nice touch.

Updated the github and the broken links, apologies it took so long.
