        Woohooo! Congrats to both of you. Also a great name choice surely he’ll be proud of once grown up!

        My Congratulations, Dave!
        (and a cool sleeper =))

      • Kiore

        Congratulations, Dave!
        I started a project like that 22 years ago, 6 builds later and I still couldn’t fix the random sleep mode. best of luck with your model.

      • Tom

        Congrats to you both :) a very worth project to spend all your time on!

      • Me

        we want more project like this.

      • http://truthspew.wordpress.com Tony P

        Very cool name! Best wishes for the future!

      • Björn Jahn

        Congratulations Dave.

        I have followed your shows for quite some time and this must be the greatest project yet.

        Would you mind comparing this to the Swedish investment for this type of project? The normal calculation is 1.000.000 SEK/revision (Not counting all the different types of state funding and subsidized external support services that all projects of this type receives)
        Converting our cotton money to your plastic money it comes to about $150.150.

        What do you calculate is the ROI? 😉

        I wish you all best of luck!


        • Björn Jahn

          Oh, forgot to say.
          Love the name!

      • Bearman

        Congratulations to you and Nicole. Best of everything to you and your family. Best blog yet.


      • Dan

        Congrats Dave, we have a 19 month old at home and another on the way. Lots of good times and sleepless nights ahead good luck to you and your family.


      • Joe

        Hi Dave,
        best wishes to you both. (You an your factory :D) Hope frequency stability is good and you find a good debugging interface.
        Keep it on. You’re great.
        Greetings from Germany,

      • André S.

        Great review, lots of fun.
        Best wishes to the three of you.

        Congratulations to both!
        You just wait until teeth start coming out…
        made me question evolution altogether…

        Hi Dave, Congratulations to your wife and you!

      • Nick Gammon

        Congratulations to both of you! You will probably be in sleep mode soon, too! 😉

        BTW what happened to EEVblog #174?

      • George Herold

        Well done Dave! (I guess your wife helped a bit.)


      • Rick

        Congrats! I love the EEV blog and this posting is one of my favorites.


      • Elisa

        Congratulations to both of You :) awesome project and awesome design 😉 and the rompers just got me killed… 😀 I bet when I’ll start such a project on my own, my business partner will insist on cover like that… 😀

      • sak

        Congratulations Dave. He is a beauty. Best project ever.

      • Chic

        heartiest congratulations and bestwishes to all three of you!!

        Is this your first neural project?

        I have two. Both where lots of fun. One with a male connector and one with female connector. They are even fully autonomous now.

      • Thundersqueak

        WOW 😀 Congrats!

        I have been wanting to start a similar project for a while. However seeing one of my friends recent projects (Project Ember), I realized how leaky they can be o.o At least it was designed with a leak detection alarm. Have you implemented that? If not, might be a good idea.


      • Nathan Knappenburger

        Congratulations, the random sleep mode issue will come and go, projects like this one have a tendency to consume you and take up whole rooms in your house. Once the hug function is working properly you somehow forget all the programming bugs up to then. Power consumption these things always seem warm to the touch, and the waste removal systems are troublesome until the automation program starts working reliably.

        Congratulations Dave and ‘Mrs Dave’, what a ripper little project you have there! I have a couple of those projects underway myself, a revision 16 female carbon based lifeform, and an advanced AI, well he thinks it is, revision 19 carbon based lifeform. Its great, after about revision 4 or 5 the batteries stop leaking, and their mouth seals work!

        Good on ya Dave!

      • Shane van Ingen

        Congratulations Dave and Family,

        Love your new project. I have one of mine I’m still working on at the moment. She thinks she is Rev18 but she is still only Rev3.
        Best project anyone could ever work on.
        Wait about 10 years and then they start requiring upgrades and it cost a lot of money to power the batteries so have your wallet ready :-)

        Best wishes to you all

        I guess you will keep that project ‘under wraps’ for a few years eh?

      • Matt

        The miracle of life!! Awesome!

        Congratulations to both you and Nicole from the great state of Texas!

        I started my 8 year old boy soldering kits together already. Now you have an excuse to buy more electronic stuff when he gets older. Just remember when you bring home a new “electronic” toy its always to “teach” the boy a useful skill that will benefit them for their entire life…electronics.

      • Josh

        Take it APART!

        Seriously, I guess thats the end of the EEV blog.

        Congrats on the baby. There is no rational explanation for why we you should be a parent. If you look at the cost benefit analysis, having a kid is a terrible, terrible idea. You will have less time for yourself, less money, less sleep, and on and on. The benefits? Impossible to explain or quantify! So whats the benefit? The best I’ve heard is that it will make you into a worthwhile person. Its a decision you will probably never regret or think twice about.

        Good luck, I’m certain you will be a kick ass dad.

        Woah, this is a pretty serious undertaking. It looks like you got some good results so far. I don’t know how you feel about doing a teardown? 😉


      • Vane

        Congratulations Dave!!!

      • Michael K.

        Congratulations, Mrs.Dave(?) and Dave!
        I started a project like that 7 years ago. Today, 2 builds later the debugging process is going on and on but works quite well ;-). Instructables.com helps me a lot to find ideas what projects I can do with these unfinished neuroelectronics projects to stimulate them.

        My (science) Book Tip:
        – “Goedel, Escher, Bach: An Eternal Golden Braid”
        – “Enchanted Looms: Conscious Networks in Brains and Computers”
        – “Neural Smithing: Supervised Learning in Feedforward Artificial Neural Networks”

        Best of luck with your model.


      • Brodieman

        Am I the only one who nearly spat my beer out when I heard about how it started as a ‘doodle in dave-CAD’. Love it!

        Congrats to you both – I am a 27 yo prototype whose project managers decided that they got it right when they flashed the initial firmware. a few broken solder joints here and there but reflowing on the beach helped.

        My project managers ended up giving their prototype to the military, and now their little project is on the way to REPRAP itself now!

        Congratulation ! :)) “neuro-electronics” :))

      • Michael

        Hi Dave,

        We got our baby one year ago and me and her watched your show together. She was only a week old and you were the first youtube video she saw. Actually it was the best thing to get her alseep when she was crying. So i didn’t mind either 😉

      • http://wallastech.blogspot.com/ walter delbono

        congratulatioooooooooooooooooooooons… beautiful baby… :) <3

      • dexter

        Ha ha here’s one project you’ll never be able to debug, well I never did and I had two goes 18 & 16yrs ago. fun times ahead congrats to the jones family.

      • Jim

        Congrats. on your new lifeform !

        Please don’t do a teardown on Sagan until he is a teenager.

        You could have named it MYERs or Coles to keep in family tradition!!
