Hello, for this toy I used:
-a box of 15 by 8 cm.
-one dc motor with built-reducing, recycling an old telephone switchboard.
-one driver l293d motor, H-bridge
-a toggle switch and a push for detecting the position.
-as control device I used a atmega 328 Arduino programmable board, I hope to exchange it for a smaller microcontroller.
-as feeding, I recycled the switching power charger phone, provides 5V, 120mA, more than enough.

    I can see your point of view also. i think you are an intuitive person who sees things fast. But yeah not everyone sees things as clearly and remember some people and children come here to learn so they can build for themselves, but we all have to start somewhere. I have just found a lot of people, recently: who have come here to show off and not really instruct others. That upsets me because i have always seen this place as somewhere to come and learn. And to teach others. Thank you for seeing another viewpoint.

    Okay?! This is alright, but... It needs more. I love instructables but it has to be just that, you instruct. I know there are a dozen other instructables that show how to build a useless machine but that doesn't mean you should try any less. Not trying to be mean.

    Hi, I do not quite understand your reasoning, what I mean to simply give some clues about fitting, not give everything fact, I encourage people to use their ability to develop ideas, and I think if you give too many details, stop be something interesting and becomes simply replicate. I am more in favor of that if people have questions, then, are well expressed and help. But I think it is good to challenge yourself intellectually and be the one to find solutions.
    They are merely points of view. I believe I offer more than enough information, and if anyone has a question, glad to help.
    Greetings, thanks for the comment.

    Although I must admit that maybe I should have been more instructive.
    Maybe my mistake is to think that people who look at these things, see the same things that I look and I assume that actions should clarify more.
    Thanks for giving me your opinion, I think you're right, I will try to change.
