All About Circuits
- taliesinb 12y agoChrist I remember this from when I was a teenager. It inspired me to build a coilgun. Really glad to see it's still going!
- ivraatiems 12y agoLikewise! This was a huge help to me in my logic, circuits and architecture classes. As a pure computer science major, I was relieved to have a solid reference for the "hard" (as in hardware) stuff.
- danesparza 12y agoIsn't this a pretty old site? I previously bookmarked this site 6 years ago...
- Gracana 12y agoI remember it from back in the day as well. I was surprised to see it with a nice modern flat design; it certainly didn't look that way the last time I visited.
- TwiztidK 12y agoYes. I've been using this site since I started an internship at a power company in high school and I used it all the way through undergrad too. It just looks like they redid the design.
- ocb 12y agoWas it responsive before? If it wasn't, it is now. Great and readable on my phone.
- dang 12y agoOld sites that are good sites are welcome on Hacker News.
- bowmessage 12y agoThis site has been indispensable to me throughout my degree, and I know I'll be using it a lot this year as well. Happy to see their redesign!
- fnordfnordfnord 12y agoSee also Socratic Electronics http://www.ibiblio.org/kuphaldt/socratic/ http://www.ibiblio.org/kuphaldt/socratic/
- MichaelAO 12y agoThis is exactly why I posted it. I'm taking circuits this semester and just spent the past few hours on the site. The university lectures I've attended leave out a lot of the practical tidbits that help the learning process. Are there any other online resources (similar to this) you'd recommend?
- nitrogen 12y agoI enjoyed and learned a lot from MITx 6.002x (Circuits and Electronics): https://6002x.mitx.mit.edu/ https://6002x.mitx.mit.edu/
- 2muchcoffeeman 12y agoNot online, but offline http://www.amazon.com/The-Art-Electronics-Paul-Horowitz/dp/0521370957 http://www.amazon.com/The-Art-Electronics-Paul-Horowitz/dp/0...
- analog31 12y agoIn addition to The Art of Electronics, as mentioned, it might also be worth trying LTSpice, which is a free circuit simulator. It's a Windows program, but I've had it running just fine on a Linux box under Wine emulation.
- tjradcliffe 12y agoAlso worth checking out: http://www.amazon.com/Electronic-Devices-Frustration-Mountains-Engineer/dp/0316368083/ref=sr_1_fkmr1_1?ie=UTF8&qid=1410154276&sr=8-1-fkmr1&keywords=how+to+build+working+electronic+circuts+engineering+degree http://www.amazon.com/Electronic-Devices-Frustration-Mountai... It provides any number of valuable heuristics for practical circuit design that often excessively theory-oriented EE programs won't teach you. This book saved my butt in grad school and has been useful on-and-off ever since.
- ddingus 12y agoNew to me, and quite useful for a hobby project. Thanks!
- kumarski 12y agoI would highly recommend reading: http://www.amazon.com/gp/product/013046404X/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 http://www.amazon.com/gp/product/013046404X/ref=oh_aui_detai... For anyone who is non-technical and needs a quick overview.
- programmarchy 12y agoI like that there is a PDF version for each chapter (linked on the left.) Good for offline reading, and no ads.
- analog31 12y agoHow much do folks who learned electronics feel that they were, or would have been, helped by introducing electron flow before switching to the mainstream sign convention for current?
- madengr 12y agoI was taught electron flow from the get-go in high school, as it correctly represents electron emission off a hot cathode. I still use it, except I have to think backwards when using a current meter or simulation software, as the industry standard is conventional flow.
- analog31 12y agoOddly enough, I learned about vacuum tubes but never did anything with them except repair guitar amps. But I can see where an introduction to tube circuitry would want to start with electron flow.
- snarfy 12y agoI was taught the same way. I was originally pretty confused by the symbol for a diode, more so because I was dealing with free wheeling diodes at the time.
- tobinfricke 12y agoIt wouldn't have helped at all. Until you get into device physics, the actual magnitude and sign of the charge carrier is totally irrelevant.
- analog31 12y agoThat was kinda my experience too. The mental training wheels that I came up with were based on remembering that like charges repel, so the electrons flee the negative terminal. But it didn't take me very long to simply regard voltage and charge as quantities of "stuff" related by equations.

- vesche 12y agoGreat to read through these for a brush up, thank you.
- zeeshanm 12y agoI used to read this stuff during my undergrad. Although, I haven't been doing electronics stuff lately, I'd want to go back to it in the near future. Thanks for sharing!
- batiudrami 12y agoA similar website for university-level maths is Paul's Online Math Notes[1]. Much better than any of the lecturers I had at uni. [1] http://tutorial.math.lamar.edu/ http://tutorial.math.lamar.edu/
- Zombieball 12y agoI can't but help give my whole-hearted +1 for Paul's Online Math Notes. This website helped me through numerous university engineering courses.
- poseid 12y agointeresting - what I think is missing is nice ways to share circuits in the web, e.g. with JSON and/or JavaScript. There is http://wavedrom.com/ http://wavedrom.com/ for signals, but nothing for schematics/layouts. Anyone interested to see this/collaborate on this?
- compumike 12y agoWe did this at CircuitLab, and even did an integration with Electronics StackExchange last year: https://www.circuitlab.com/blog/2013/03/06/circuitlab-integration-on-electronics-stack-exchange/ https://www.circuitlab.com/blog/2013/03/06/circuitlab-integr...
- sprite 12y agoI wish there was an online course with a built in circuit simulator and labs.
- hobofan 12y agoThe MITx course on Circuits and Electronics[0] has that. [0] https://www.edx.org/course/mitx/mitx-6-002x-circuits-electronics-2606#.VA1opsv8Im8 https://www.edx.org/course/mitx/mitx-6-002x-circuits-electro...
- netcan 12y agoThis is a great format for e learning, a very usabletexbook with quizes, videos, forums etc built around it.
- valdiorn 12y agoAll About Circuits is great, I was able to teach myself the fundamentals of electronics using that site, and it got me interested enough to go do electrical engineering in university, a decision I don't regret. another fantastic site, that caters EE/CE content to "the average Joe" is http://www.dspguide.com http://www.dspguide.com , it provides you with the basics in Digital signal processing in terms most high-school students could understand. Great site.
- schappim 12y agoI love this site. I also highly recommend the tutorials on http://learn.sparkfun.com http://learn.sparkfun.com .
- edtechdev 12y agoThis animated circuit simulation can help students conceptually understand what is happening in the circuits they learn about in the first 2-3 college circuit courses: http://falstad.com/circuit/ http://falstad.com/circuit/ (it's a java applet, but it was ported to ios/android with the icircuit app) I tutored students with a modified version of this simulation and they learned in less than a half hour stuff they hadn't learned after 2 circuit courses.
- fnordfnordfnord 12y agoI also like everycircuit ~$10 IIRC, very good interactive circuit sim.
- chris_wot 12y agoI have to ask - are there any good physical kits that you can use to put together circuits?
- TheCraiggers 12y agoPhysical kits? Do you mean like a breadboard? That should give you a great platform for putting together circuits for learning or testing purposes. If not that than I don't understand your question.
- gwhismagm 12y agoI love crickets because I have one at my house and I came to see how to take care of it i just got it so.
