Great resource! I've got an old price of gear with some nice components, and would love to learn how to break it down and build a custom module. It's a Roland SP-808. It has an oscillator and a really cool back of effects.

EMS 2006

I've been served notice of a copyright claim to songs used in this lecture. I disputed them seeing as it's fair use to demo parts of music for learning. Response from reviewers was denied...they probably have automated this part of the process also.

If anyone has issues with playback let me know, I'll find a place to re-post.
I have these courses all backed up.

Just watched the first two lectures, which were very informative, then the links quit working. Fair use doesn't seem to apply to popular music in the age of internet spiders from lawyers. Hope the lectures can be reposted, even if you have to cut the recorded examples. Thanks for keeping on trying! :tu:

I'm new here and beginner at eurorack DIY. I was wondering if there is any place to start/simple example circuits to start with for voltage to frequencies conversion? I know that it might be a popular question in that forum, but I can't found anything yet. Just to be more detailed, I'm using the pitch out and gate cv out of a micro brute to my new VCO prototype (555 IC based) but without any kind of conversion circuit, I can't seem to have accurate pitch/notes out of my VCO. Thanks for your advices!

Hello dear DIYers.I found some metarial for you.Here is the online courses about Analog Electronics.These lessons are from METU which is the best university in Tukey.Instructor has very awful pronunciation i hope you can understand.Also you can download lecture notes in PDF format.

Analog electronis course page:
http://ocw.metu.edu.tr/course/view.php?id=105&lang=en

(TOPICS: Basic single-stage transistor amplifiers and frequency responses. Multi-stage amplifiers. Feedback in amplifiers. Differential pair stages. Current mirrors. Operational amplifiers. Power amplifiers. Power supplies and regulators.)


Fundamentals of Electrical and Electronics Engineering course page:
http://ocw.metu.edu.tr/course/view.php?id=131&lang=en

(there is NO video lesson in this course,just lecture notes)

(TOPICS: Basic Principles of Electricity, Circuit Analysis, AC Circuits, AC Power, Phasors, Three Phase Systems,Transformers, Magnetic Circuits, Electrical Safety)

Hi Wigglers!

Im a long time synth noodler and forum lurker, but finally making the jump into DIY and would like to ask for a bit of help.
I ordered musicpcb Gristleizer and Echo Base delay PCBs.
I have the pdf guides from musicpcb, but i'm a little confused by the BOM.
Is there somewhere on the forum where someone who has built one might be able to check over my BOM before I order it?

Thanks in advance!

Great thread! :yay:

I knew you guys would have what I was looking for.

My iron (Hakko) and other needed tools showed up yesterday, and I'm waiting on a little Thonk EQ and attenuator modules. Then I have Penrose Quantizer lined up, followed by a Turing Machine II+ Volts. If all goes well, the plan is to then add a dual LPG, Befaco Rampage and then get on the TWO59 VCOs and waveshaper (saving these for last). That alone is a nice setup, in addition to what other modules I already have. I just can no longer keep buying brand new $500 modules, and I'm hoping the labor of love will only increase my understanding of, and interest in modular synthesis. I'm new to west coast stuff, and that's basically the goal with the DIY.

That should be enough to keep me busy for a while, eh?

I've wanted to do this for a while, and have some time off for a few months starting now. I will devour these resources and rely on my conscientiousness and obsessiveness to get the job done.

I'll keep you guys posted on how things go. Can't wait to get a work station set up, and get started

Wouldn't the hyve synth project be a great way to learn smd soldering? [video][/video]

Yes and now you get 2 PCBs for the price of one. But this is the last day to get one on Kickstarter: https://www.kickstarter.com/projects/sk ... cal-expres

I'm attempting to put one of these [Zlob VCA] together but have a basic question:

This image (taken from the build guide) looks like the top side of the resistors leg has been soldered:

Is it just solder that leaked through from the underside or am I missing something?
Looking at the underside of the board I saw no trace lines either which added to my not sure-ness...
...but Cynthia, my Daddy never had a heath kit..

Wow this thread is amazing, thank you all. The EMS lectures are gold.
I've been getting into DIY for the past 6 months, just mainly Kits for now. But I've started designing my own eurorack audio mixer using eagle and I'm having trouble looking for parts ie: sliding potentiometers, Does anyone know of any good librarys for snyth related parts.
Thanks

PS: sorry if this is the wrong place to ask, Im pretty new to Muffwiggler.

Note priority

Post by Semeionart113 » Mon Jan 29, 2018 6:52 pm

Hello everyone, I'm trying to build a simple synth to play around with and learn how they work. So far I've built this monophonic circuit by a guy named Pete Mcbennett who appears to have abandoned his YouTube channel.
That's the link to the video...heres the schematic.

Everything was built and worked first try, problem is that when you hit more than one key it gives some higher note that isn't even in the octave range I've tuned it for. I've gathered that this isn't exactly a standard vco type tone generator. I've searched everywhere trying to find some information on how note priority is implemented into this type of circuit. Would it be mechanical? Maybe breaking connection to lower notes when higher note is played? And information to help me push this project forward would be so greatly appreciated. This is my first post by the way, happy to find a community of like minded people.

I just did a quick ctrl-f of this thread, and I didn't see the EEVblog listed as a resource for learning electronics.

Many of the topics covered aren't particularly useful to the crowd here, but many of them are.
