No boys allowed to work on this project haha

Nope! I juat go straight from the breadboard to stripboard with a little planning and just go for it. I would get PCBs made for kits to sell if I ever get around to that. Working on a sequencer right now, too, similar to baby 8 but with different multiplex chips. So many wires lol. Good luck with the pedal sequencer!

Life and work and stuff, you know. Got some new things in the works!

Thanks! You might like my stylophone build, but conductive touch triggers would be cool.

I actually scavenged a bunch of power adapters from my work! I try to upcycle parts as much as possible, I get my capacitors and diodes from old CFL light bulbs or other old electronics. That's really cool you have access to a maker space. Support our local libraries!

It's the 10k resistor for the LED. Sorry it wasn't clear! At least it's on the schematic.

And a bit phonish!

Hi! The parts list is on my website, observerb.com. click on education, and you'll see the 40106 project. Good luck, and let me know how else I can help!

Can't be sure without a schematic, the folks on r/synthdiy on reddit would be a good place to post a pic and ask. If I had to guess, the vc would need to operate the LED, but none of my designs are really all that compatible with standard eurorack voltages, so be careful.

Thanks so much for listening! I'm glad you appreciated it.

I haven't tried voltage control, since it would be tricky to get it to be 1v per octave, so I went the easier route with the resistance. I keep things pretty simple, but Moritz Klein has some more advanced diy synths that can do 1v per octave. Maybe I'll try a variable power source and see how that affects things for the fun of it and let ya know.

Aaah... understood that makes complete sense. thank you...

Yeah it is

Is there a way to add VC to oscillator? Thank you!

Yeah, dude! Thanks for hanging during the live stream of the stylophone 🤘

Thanks! 🍌

I love to hear that, glad you liked it!

@@observerb ...and I finally finished it (had to find some parts) Thank you, awesome learning experience. Do you have an insta account? I posted the end result there

Awesoooome. I always wonder about all the little bleepy bloop machines that have come into existence because of these vids haha. I would love to see it! Pop a link to it here and I'll check it out.

@@observerb the LED isnt working correctly (inverted) otherwise seems fine. I put a link in another message here

@@observerb youtube seems to delete links to insta... i'm there under @niemandenruiijs

It sure is haha I like your attitude

Yes! I'm going to make a vid on that soon, I do it with different chips, but same concept. Also about to drop a vid about making these a bit more modular, should be done by the end of the month.

It'll totally work with 9v, I made one like that for my guitar player to run through his pedal board. It lasts a good while.

De nada y gracias!

Thanks for the kind words! When going to perfboard, I use chip sockets, it makes it easy to swap a chip if one burns out. I use a drill to to break the connections on the board, like in the middle of a chip, making sure there is no copper on those spots, but not drilling all the way through the board. I've had problems befire with "cold solder joints" where all of the connections look good, but aren't actually connected. Try re-flowing all of the joints, it has fixed synths for me that weren't working or had stopped working. Good luck!

It's uf

@@observerb thank you!!

If you're using a smaller (than 1uF) cap then it gives a hi-pass (RC) filter AFAIK. It's about the AC coupling, right?

Thanks so much! Glad you enjoyed it.

Hell yeah, if you run into any issues just drop a comment and I'll help out!

That's so great to hear! Making this kind of music is so meditative, it helps me calm my brain, too.

You're very welcome, sir!

Yeah, they're chock full of goodies! Have fun cracking them open.

So far nothing more than messy ones in my notebook, I've been wanting to make a full fledged vid on this for a while. It's on the list! It's based on a 4016 multiplex and 4017 decade counter if you want to check those out. 4016 chips aren't typical for this, but I got them by accident when trying to get 40106 chips haha. They get the job done. A Baby 8 sequencer is very similar if you want to check out schematics for that, there are tons since it's a popular basic diy sequencer.

Gotta keep your eye on em!

No, I just should have pushed it in more, oops. Had my hands full filming and trying to do all the things.

Thanks for watching, I'm glad it helped!

Check out my LFO filter vid, you could use the vactrol to control an oscillator's pitch instead of the filter. Might take some fine tuning, but it could work!

Thanks! Got a few more planned for the future.

Thank you!

Hell yeah, that'll sound awesome with delay. I'll probably mod mine with a switch to have a sync mode.

Uh oh! Probably an unwanted connection or a bad potentiometer. If it makes you feel better, I have a pile of failed builds that's much larger than my successes. If you have it on a breadboard, you can at least tear it apart and try again. If it's soldered, might have to salvage the parts you can and give it another shot. Good luck!

The 40106 chip is about a dollar, the most expensive components are the potentiometers, about $10 worth of parts.

@@observerb That is incredible! I want to try this! Thanks!

Thanks for the kind words! Triple sync drone all the way, I bet that sounds gnarly.

So many possibilities with this chip! I've run it through my Poly D (mini moog clone) filter and sequencer and it sounds amazing.

Thanks for the kind words!
