Author DIY learning resources
handsfelloff
 Hey wigglers! This is my first appearance here so hello! Although I have been lurking around the muff street corners trying to absorb as much diy electronics knowledge floating around here from the many experts. I wanted to start a thread to share quality diy electronics learning material to help people like myself wanting to build and understand diy circuits. From my point of view i am after some comprehensive step by step self learning course material that does not jump in at the deep end or bail out at the shallow end. Rather guiding the novice through circuit principle physics and theory backed up with practical experimentation taking them to a level where a schematic makes sense and having and idea how to implement design ideas. Plus make some useful and interesting circuits along the way! heres some I have found that will hopefully be useful and help get the ball rolling.. (novice - intermediate) http://www.allaboutcircuits.com my favorite at the moment. this really fulfills my above wishes from the basics to building tube preamps all the way making sense of the theory with practical experiments. everything you need to start. very nice resource http://www.kpsec.freeuk.com Good for an uncluttered insight into the basic circuit components and simple physics/math theory (intermediate/advanced) http://users.ece.gatech.edu/~lanterma/ems/ Electronics for Music Synthesis Course Online (Listed by B13 previously) A great video resource a full uni course online! Funny guy....he prances around when he gets excited about circuits A pity he left auto focus on which can make his board work hard to follow...but hey its free!..Also to bear in mind after scribbling math equations on the board and saying "anyway you guys know all this but any questions?" its futile to raise a hand... so this is a course for people who have the basics under their belt. however even for the novice its worth watching some then jumping to the Internet to find ask questions.. Anyway hello wigglers hope this is of some use and I will watch out with interest for any other resources. Plus will add more to this thread as I come across them Cheers!

 Welcome! They are some nice links there- Aaron Lanterma's course looks well worth investigating. The freek website is a favourite for CMOS information & theory (schematic symbols, etc). I found Curious Inventor's soldering videos very helpful when i started out- http://curiousinventor.com/ I tend to bookmark stuff i _plan_ to come back to, but instead i find that i do all my learning when i've got a pcb in front of me that needs to turn into a working circuit, and i learn from the BOM's, notes, and others' trials & errors, while making many of my own along the way (errors). I'm kind of gleaning my way to a self-built modular. But ultimately i want to be at a level where i'm confident enough to build a tube synthesizer (hopefully by the end of 2009). There are some really exciting DIY circuits being researched and shared on the electro-music forum, and of course Bridechamber seems to be an ever-expanding one-stop shop for excellent kits. If there's one thing that i see referred to all the time as a benchmark for DIY synth circuits, it's Electronotes- http://electronotes.netfirms.com/

 This is something I've maintained and advertised on the Synth-DIY list in the past: Det3 Synthesizer Book List I've got everything in there from general engineering books for AC/DC and semiconductors up to bad-ass digital processing and crazy filters. Plus, if I'm missing anything in print or in treeware format, please let me know.

 Hi, this is my first post. Hello all!! I'm just starting to dip my toes into electronics as I plan to build some modules from other people's designs and perhaps even design my own one day. This thread is a great resource and I'm learning a lot from some of these links. Can I recommend to make this post a sticky?

 Some great links guys. A few more fish from my daily web trawls... Impedance a practical understanding and nice tutorials http://gaussmarkov.net/wordpress/thoughts/input-and-output-impedance/ A nice practical explanation (not too in your face math) on the input impedance subject. Also generally a good practical happy electronics focused on guitar stompbox for beginners and another perspective for intermediate refesh(helped me audibly click on the impedance subject). Also check out the other electronics tutorials some nice simple and uncluttered circuit explanation. PCB Layout design http://alternatezone.com/electronics/files/PCBDesignTutorialRevA.pdf A Brilliant guide to get you on the right road to designing your homebrew-professional pcb's. DIY PCB on a shoestring it works well and really cheap http://myweb.cableone.net/wheedal/pcb.htm http://www.riccibitti.com/pcb/pcb.htm A couple of simple step by step tutorials tp great consistantly good pcb etches with toner transfer and magazine paper. Much cheaper than press N peel infact just the cost of toner ink! I can say it works just as well. Hope these are of use. Enjoy!

 I have been looking at the faceplate etching thread and wondering if there are any good resources or books for teaching metal work that would apply to DIY? I wouldn't know where to begin trying things like some of you are doing. I have wondered how people get silkscreened letters on their own DIY creations, even just drilling holes in metal, etc. I have noticed most DIY metal work books are focused towards jewelry making. I've never even drilled holes in metal and from what I've found online you need to use a drill press, place a piece of wood behind where you will drill, drill front to back, etc... and I was wondering where all of you started since it seems more complicated than I thought. Or am I overcomplicating things? Thanks for any suggestions!

 Great information! I'm starting to get bit by the DIY bug. A month or so ago, I had this dream about this polyphonic, semi-modular synth box that I am determined someday to create. Realistically, I'm a ways off from that but these resources will give me a good start on trying reverse engineer my "dream synth". Someday...
craque
 I realize that these aren't "online" resources but I'm rarely "online" when I'm tinkering/building/breadboarding so they do me very well. Everything listed here except for the first book were published after I started into the DIY world of audio, and after spending literally DAYS of searching and reading electronics tutorials and articles online, they have become my 'go-to' stack for reference and inspiration. 1. If you aren't familiar with Forrest Mims, get familiar with him. I just picked up Vol I. of his "Engineer's Mini Notebook" series, which is titled: Timer, Op Amp & Optoelectronic Circuits & Projects. It should have been titled: The Building Blocks of Analog Modular Synthesis, and I wish I had discovered it five years ago when I first started into building this stuff, cause it is indispensable. All the "how do i build a 555 timer?" and "how do i correctly power an opamp?" or "what frequencies do i get if i change these resistors?" questions that you search for hours on the Internet? It's all in here - there's even a chapter on photocouplers - aka 'varactors' - which are used a lot for CV audio systems. 2. Another specific project-oriented book but much more glossy and full of awesome examples and a DVD (which I haven't gotten around to watching yet, shame on me) is Handmade Electronic Music by Nicolas Collins. This one is specific to DIY audio hacking and electronic building, covering everything from building oscillators (different chips than the Mims books!) to circuit bending and experimental electronics. 3. Make has started releasing awesome print publications (I have two of the Maker's Notebooks and love them). The one I've found the most applicable and helpful to audio DIY is by Charles Platt and is one of the first: Make: Electronics. Simple, easy to understand tutorials on the foundations of... well, making stuff. With Electronics. 4. Finally the most general of all of them but something that is a great learning resource for a wide range of electronic applications, by Michael Jay Geier, How to Diagnose and Fix Everything Electronic. The title doesn't lie. Every chapter is basically a Cliff's Notes on that particular subject or piece of equipment, summarizing how it works, what might go wrong with it or often does, and how to troubleshoot and fix it. It also includes quick introductions to fundamentals of physics and other things related to electronic parts and machines... and most importantly to us, a wonderful introduction to oscilloscopes and how to both choose and use them. All these books together will probably cost you as much as a good VCO module! But they are worth it, I highly recommend any of these to the DIY audio muffer.

I see it's been a few months since you posted this, but if you are still looking I suggest buying the pdfs on Magic Smoke Electronics. While you're at it, get the Electronic Drum Cookbook! Circuits in both of these books are easy enough to make and experiment with a solderless breadboard, even if you are just beginning.
Also, Horowitz and Hill's "The Art of Electronics" is a great read and resource. The third edition of the book "might be coming out in late 2013".. happy soldering!

 I'm sure many are aware of Ray Wilson, but I would like to bring up his book, Make: Analog Synthesizers. http://www.amazon.com/Make-Analog-Synthesizers-Ray-Wilson/dp/144934522 0/ref=sr_1_1?ie=UTF8&qid=1367955744&sr=8-1&keywords=make+analog+synthe sizers This book helped me get a basic grasp of what analog synthesizers are. A lot of his circuits make some pretty nice sounds/filtering, and they aren't too complex. I think this book is pretty good for beginners. Also, of course, his website, Music From Outer Space is awesome http://musicfromouterspace.com/

it's definitely very useful and for some things even necessary, but a lot can be done if you're just able to apply ohm's law, kirchoff's law and some trial and error prototyping.

 Dunno if this counts as a learning resource, but it looks pretty handy for beginners (even if they're not producing their own SMT boards). Via Upverter:
rotallicso
 There are definitely some great useful resources listed here already. As others have mentioned, googling is not as rewarding as usual, it really takes those with insights to find (and share) the location of those needles in the haystack ... anyway, i'm still curious to establish if there's a front-runner or indeed a real-world benefit to using any of the free circuit simulators available - i'm thinking beyond examples where you could derive the answer from first principles and looking for something where you may be able to predict (and scope) the output of e.g a circuit using a 555 timer chip ? . any thoughts on this are welcome . ps: cutting to the chase scene, any links (or thoughts) to a proven simple chip-less circuit that i could 'passively' embed in a cable to convert a gate-on to a trigger/pulse (along the lines of those that convert v-trig to s-trig) ?
Elest
 I am searching for some information regardin the synthesis domain, such as how voltage / digital are best to be handled and I am also on the search for some materials of the electronic side, as they are shown here but slightly more pointed to technical / functioning issues despite of how they have to be implemented throught the parts, etc.

 Does anyone know where i can learn how to buy cable from amazon. I need to connect pots and jacks to my circuit boards.. so far I've only found cable that is far too thick to work with and stuff that is so thin as to seem like i probably shouldn't use it for audio signals. I've spent ages searching local stores and amazon and had no idea finding cable would be so difficult. There's far too much of it and i know have even less of an idea what i'm looking for than when I started.

 one more approach to learning here, especially suited for me because the info is somewhat compactly presented, and there are simple, also for me in real life quickly doable schematics for alot of things, for example a simple unity gain audio mixer in the op amps section. a good way to get going before looking into more optimised designs. http://www.learnabout-electronics.org/index.php i mean, i tried to delve into a couple of textbooks, but that somehow always ends before i get through the initial 10 pages of filosofy from the author...

 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.

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.

 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!

 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! 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

 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. https://youtu.be/yZSkNASlMjM That's the link to the video...heres the schematic. https://drive.google.com/file/d/0Bzxodk3UiKRgSXc0OVBWQnNfM00/view 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.

Many of the topics covered aren't particularly useful to the crowd here, but many of them are. https://www.eevblog.com https://www.youtube.com/user/EEVblog Op amps: https://www.youtube.com/watch?v=7FYHt5XviKc&list=PLvOlSehNtuHu2FviAaZa iyXwN41G4b1Lf Soldering: https://www.youtube.com/watch?v=jSZbkR9vNzI&list=PLC7B2B77C240A3B12 Capacitors: https://www.youtube.com/watch?v=xlvqUts9H9c&list=PLvOlSehNtuHvpVeLXSGl S7EBlY3zKfIXh

 Plenty of really good stuff here for the electronics side of things...I’m feeling a bit overwhelmed! So I’ve been building kits now for a little while and have decided to learn a bit more about electronics so I can understand how the circuits work (hopefully). I’m currently going through the online course that was posted here along with some forest mims books and random searches for data sheets etc on the internet. One thing I know is I hate breadboarding, it seems really fiddly and I soon lose track of what’s going on. I’m guessing there is some software that would do the same but in the software realm? Any recommendations? What about all the other parts of the diy? Panel and PCB design? I think I’m ready to get into learning how to design my own circuits, pcbs and panels. Any pointers for resources for those would be much appreciated.

 Wow, this is a great list for someone who is just getting into DIY. Thanks for all these resources! Because of this list, I've got up the courage to get a MFOS PCB and have ordered the parts I need for my first project.

 Any good resources for calibrating and troubleshooting synths? I.e Something that talks about how to properly use an oscilloscope (got a rigol ds1054z) since I think my re-303 is sound a bit weird due too improper calibration

 And here I was thinking I would have to buy a \$200 book to learn this stuff

 Anyone know of any decent audio books or podcasts for learning this sort of thing?

 Hi, I'm quite new to this and I'm really bad with schematics. Could please someone help me with this simple schematic? Would be perfect to see how it works on breadboard or even a "simple" draw Many Thanks in advance

 Hi All Thanks a lot for this wonderful thread !!!! Very cool stuff !
johnstilton
 A lot of the older links are unsurprisingly broken such as a lot of the technical articles by Ken Stone which seem to be held in high esteem here. After a lot of pecking I found a meta-archive of a lot of the CGS designs here: http://www.elby-designs.com/webtek/cgs/cgs.htm Does anyone else know where some more of the scholarly articles may be archived?
johnstilton
 Some interesting articles and examples I have also found that I didn’t see in this thread, including an article about CEM/SMM ICs: https://electricdruid.net/category/projects/
Revok
 The CGS stuff can all be found on archive.org. https://web.archive.org/web/20150315062321/http://www.cgs.synth.net:80  / Here's a couple other good ones if you haven't seen them yet: https://www.birthofasynth.com/index.html https://www.schmitzbits.de/

Hi
it's not exactly scholarly articles, but, it's a fantastic goldmine of resource which explain what happen in electronic circuit ....

No math formulas just see what happen with voltage, current and resistor in real time.
And you can change all the value to understand what happen ....

It s wonderful !!
Thank you J3RK for the link !

 Not for every beginner! I had a search for Lockhart here and I couldn't find anything so I thought I would post this Serge Lockhart wavefolder analysis

I was about to ask if anyone anything on wavefolding and this looks like a good place to start. Thanks.

 Hey everybody ! Does someone happen to have the book "Electronic Music Circuits: The Reprints Vol 1" by Thomas Henry in pdf ? There was a google drive link that you could easily find but its's now dead.

Synth DIY Wiki is your friend.

Go here: https://sdiy.info/wiki/

Type "Thomas Henry" into the search box.

Scroll down to "Papers and Articles"

Look at the "On Web" column, click on "Electronic Music Circuits: The Reprints, Vol 1" then on the next page click on "The_Reprint_Collection_by_Thomas_Henry_CC_BY_NC.pdf"

Enjoy the rabbit hole!
