    @Ingo: why don't you also introduce yourself here at EB.com?! (b.t.w. if you have 10 or more posts you will be able to send PM's of course).

    Tomorrow was a little bit later, but here is the finished locomotive: And a close-up of the back: It says: "don't tow locomotive". I still would like to include lightning options. It has a medium PF motor and it seems to work quite well.

    The topic almost deserved a 'sticky' status IMHO ;) I was just thinking, would it be difficult to make some 'middle ground': controlling a train as usual, but also controlling lighting functions and then not only RED / BLUE but e.g. on the red output the engine motor and on blue a peripheral output that can turn on different actuators like lights, blinkers, sounds.

    Nice work! I have succesfully worked on the same using BLE (low energy 4.0 bluetooth). The form factor is always a challenge indeed! Together with my students we are also working on a XBee powered system.

    Aitoruco that is an amazing build! Very nice indeed! Very difficult nose but you got pretty close to the real thing!

    Yups, I like the idea very much! It is not that big as the FLL yet, but a very nice way for primary schools to become involved with the FIRST LEGO League.

    very nice indeed, I like it, if you look at the upper image, it is hard to see at first that it is a LEGO microscope!

    looks very nice SandMirror38!!!
  9. JopieK
    That looks very, very nice!

    would this give you a hint: http://letsbuilditagain.com/instructions/4512/ ?!
  11. JopieK
    well, I'm not sure, can be the perspective of the picture of course!

    Nice job again lightingtiger!!! Your mocs are becoming better every time!

    if you make sure the polarity is right and the voltage is correct (DC and indeed 9V), it should just work. Don't worry about current, the power supply should be at least be able to draw enough current, but that is not a problem with just the IR tower I think (otherwise you would overheat the adapter). Be ware that the LEGO adapters are mostly AC.
  14. JopieK
    well, it should work of course, but make sure that you have DC and no AC!

    that is an amazing first post budo, why don't you also tell us something about yourself and your LEGO adventures?! Enjoy your stay at EB!

    very nice idea mattman ;)

    @Selander, fixed that ;) Thanks! The Brake van looks very nice too!

    Indeed, without the NXT it will be hard to keep up a relevant battle! I am coordinator in my school (currently 3 teams, hope to have 5 teams next year). I am also main judge in our region. Some old students of the college I used to work for, are also judges (and of course if my high school teams are playing I will not make any decisions :)). We bought 3 EV's. I think it was a mistake to already allow the EV3 with 4 motors this year. There is a supply shortage of EV3's and also the EU crisis is a big deal for schools.

    nice work Lazarus!!! I like the coal wagon best!

    I wonder if it is possible to use heat transfer on Gesso, that would make a lot of applications possible!
  21. JopieK
    well, there are solutions to that even with 9V of course (isolation, diodes, etc.)
  22. JopieK
    Looks great! Nice building techniques for the window.
  23. JopieK
    Very nice Lazarus! Now the real thing! :)
  24. JopieK
    Nice job! Why don't you also introduce yourself, we are all interested in your train experiences etc. of course here in Train Tech.
  25. JopieK
    a very versatile principle, that's for sure! Especially the nice 4-track junction with one servo!
