    The EEVblog is the world’s largest and most popular Youtube Engineering channel with over 450,000 subscribers, and hosts one of the most popular engineering community forums The EEVblog Forum (linked above).

    The EEVblog is hosted by David L. Jones, an electronics design engineer based in Sydney Australia. In each episode he shares some of his 25+ years experience in the electronics design industry in his unique non-scripted naturally enthusiastic and passionate style.
    David J. Ledger is the much younger, better looking, equally enthusiastic but less jaded sidekick.

    Dave was the first engineering blogger to become a full time Youtuber back in April 2011. It remains his full time job – entertaining and educating a vast Youtube engineering audience.
    You can see a talk on that here: Make a Living on Youtube (or die trying), a talk at Ignite Sydney #10

     The How, Why, & What

    Comments, feedback, and ideas for the next blog are appreciated!, but PLEASE, use the EEVblog forum for suggestions, not email.


    Use the social media buttons on the right hand side.
    All video is hosted on Youtube. If you want to download videos to watch later there are plenty of ways to do that through Youtube, this channel is no different.
    If you use an RSS reader/player and want the video fed to your reader, Youtube can do this! http://gdata.youtube.com/feeds/api/users/EEVblog/uploads
    But that is only for the videos. For the text blog posts, updates and things, please use the usual WordPress RSS feed as well: eevblog.com/feed
    I do not read, respond to, or post comments to Facebook. I don’t use Facebook, but I have a facebook page that gets the latest video feed if you really want to follow that way. I use Twitter a LOT. This is the best way to follow me daily on what’s happening.


    Producing and maintaining this blog takes a massive amount of time, and has been my FULL TIME JOB since April 2011. If you like the blog and want to help support it, there are several ways you can do this:
    1) Buy some of the products from my STORE
    2) Buy anything from Amazon.com by clicking through here first (I make 6% on every sale, even from 3rd party sellers), and any product, not just those in my store. Or use the Amazone search bar on the right below. If you buy from amazon regularly, this is a real easy way to donate that costs you nothing!
    3) Buy some of my Merchandise
    4) You can donate money direct through Patreon. I much prefer this over PayPal.
    5) Donate directly through PayPal using [email protected] address. But really, I prefer Patreon.
    6) Donate Bitcoins: 17sH3EErEbAaqvfDFNzjmuPLrCvwdQwxQW
    7) If you are interested in buying the PCB package DIPtrace, I have an affiliate link that gets me a very large percentage of the retail price. Just CLICK HERE before ordering.

    Helping keep the only full time engineering video blogger in the business alive and doing this also ultimately helps others and the industry too!
    If others see that I can do this full time, then that might convince them to produce great content too and have a go at it. So thanks for all the support, it helps more than just me!


    Sorry, but my videos get 75,000+ video views PER DAY, EVERY DAY, 365 DAYS A YEAR, not to mention my other technical web sites, so that means I get MANY emails and messages EACH DAY asking for personal advice on what meter or oscilloscope to buy, circuit design advice, career advice, questions on projects etc.
    Before the EEVblog it used to be a manageable level but now I can’t possibly keep up. If I answered them all and your “simple” technical inquiry I would have no time to make videos, earn a living, see my family, or have a life. So I now have no choice but to simply refuse to answer any such emails for personal advice, sorry 🙁
    I like helping people, really, I do, it’s why I do the blog, I’ve been helping people for 20+ years before email when I had to hand write reply letters and lick a stamp. But the volume is now too much, I have a life, I have a family, and I have to draw the line somewhere.
    Serious emails only PLEASE!
    BUT, I do read all email, and try to read all youtube and blog messages.

    If you want my advice on something then ask in the EEVblog Forum, and then I or someone else may respond to your question. You’ll get a better and quicker response. That’s what the forum is for, it’s an awesome resource, use it!

        I’m really interested in doing the DS1052E hack, but I can’t find the files anywhere. Any ideas?

        Anybody willing to help me out and email me the old and new versions? ;<)

        Hello David,

        Name here is Marc Brocato, live in Amite, La. USA.
        Experiment allot with various electronic stuff and some pretty crazy stuff
        sometime, I wonder if you could help me with a need. I think many other people
        would want to do this task also. The idea is to control the discharge of a cap.
        the method of charging are varied, one is static from and areal, one is from a
        joule thief and the windings I have made [some weigh many pounds] can produce
        low {12-20 volts] to high [1,500 and higher voltage]. The method of discharge
        would vary for each case. For instance, a neon light will trigger a SCR for the
        higher voltage application, but the voltage has to reach 70 or 80 volts, also
        tried using a transistor, not knowledgeable enough to pull it off. The discharge
        would go into batteries, other caps, and maybe just pulse some other device.
        Experimenters do many different things. For instance, built a Tesla hairpin
        circuit [15,000 volt neon sign transformer as a supply], this actually produces
        movement of radiant mater, very interesting experimentation, and when it is
        operating the caps with an areal connected to a few diode will charge to several
        hundred volts, the same thing happens when thunder storm are in the area, with
        no other source but atmospheric ambient static the caps run at about 10-15
        volts. Have built some nice coil lathes to make inductors. Anyway, I think that
        there are probably a number of ways to do this. I have learned that there may be
        a dozen different way to do any one task, but one will be the best and most
        simple and logical method.

        One thing I might add, the more I read about suppressed discoveries
        [seams to have happened only in the US] the more I am astounded, they ought to
        be ashamed.

        If you could help good, if not that all right
        also……hope to hear from you.

        Thanks and God Bless.

        P.S. on the low voltage design, the triggering
        voltage should be adjustable begining at 5 volts or so via a

        • You are on the wrong blog, I don’t do “suppressed discoveries”, it makes me groan just hearing it.

        Dave if ya dumpster dive and find a broke or your going to toss a garbage oscilloscope could ya send it my way.For the last 9 yrs Iv been disabled and I started following your blog for the last few yrs.When I was a teen I was into Electronics.Since my disability I have felt pretty useless.Because of your Blog it has re kindled my intrest in electronics.Iv been robbing most my parts from stuff left on the side of the road. Iam having fun and actually fixing some stuff.ohh I cant afford a used scope.But I wanted to thank you for reminding me there is still some stuff i can do and Thank you for helping me find myself useful again.Keep up the great work!

        • I don’t get scopes in the dumpster. Only one in my complex would would know what a scope is would be me.

          • Scott Prescott

            Thanks for answering Dave.My family pitched in together and purchased a Hantek 6022BL as a early Christmas present. I’v been using a meter, but I can’t wait to actually see whats going on inside a circuit.It has a logic analyzer.I have no clue how to use a logic analyzer and no experience with a oscilloscope.Could you recommend a good site or book to start me off in the right direction to learning and not harming my new scope.

        hi dave did you trademarked your name (eevblog) just in 2016? just curious 🙂

      • Daniele Pellegrini

        Hi Dave, did you ever think to prepare a video about Digital usb microscopes? A little review among the products we could find on the market, obviously related to electronic devices inspection?
        Thank you,

        Hi Dave, I just pinged you via LinkedIn about an opportunity to increase ad revenue here. Email me at michael.strong at themaven.net if you did not get the Linkedin message. Much more credibility via the LinkedIn message. This is not at all spam.

        I have a suggestion for a video. More and more I have seen people trying to use these “Hobby relays” that they get from eBay for Arduino’s and other microcontrollers, For controlling household voltage. some of these relays are extremely bad for this purpose. On some of these relays, The low-voltage comes very close to the high-voltage side. In one case, the low-voltage actually cross to the opposite side of the board and the high voltages contacts crossed to the low-voltage side of the board. In this board was supposedly designed by engineers. Quite frankly I think they were half drunk when they designed it. Fortunately they had a lot of complaints about the board design and fixed it. I feel it would be a good service to the Hobby community to point out some of the good and bad features of some of these boards. And what to look for when purchasing a good board. I would appreciate if you would consider this project. It might even save someone’s life.

        Hi Dave.

        What is the adress of your lab in Sydney?

        Best regards.

        Hi Dave.

        It could be nice and really funny if you made a (teardown) video of the CMI Fairlight. (The old versions) Maybe doing it in combination with a interview with Peter Vogel and some historical information as well. At the time it came out, it was really a piece of high tech equipment, hence fun to see how it has been pieced together.

        Best Regards.

        Hi Dave,

        This is Andy and am an electronic engineer. I am in Sydney, and wondering if anyone can provide sort of practical training especially in the field of medical device repairing.
        Its something like your pace maker circuit analysis over Youtube. I like to learn more such as medical instruments, thanks.

        I will appreciate your help like information. And my email is [email protected].
