    [MOC] Inverted spirograph

    Thanks for the feedback--yes, the linework was quite wobbly! The pens were Lego brand (with a cross-section almost the same as a 2x1 brick) but unfortunately they were a little undersized, which resulted in some play in the pen holder. If I was building it again I'd probably include some kind of locking mechanism to hold the pen. Cheers, Peter
  2. Hello! I'm a first time poster in the Technic forum, but thought that my inverted spirograph might be of interest. Rather than move the pen, I used a planetary gear setup to move the paper. Different gear combinations give different results, as does the pen position. The pen-holding frame is made up from a lot of 2 x 4 bricks, but the guts of the machine is a hard plastic wheel with internal gear teeth (I'm not sure of the correct name, but this is the part I used: http://www.bricklink.com/v2/catalog/catalogitem.page?id=83393&idColor=11#T=C&C=11). Sadly the spirograph has now been dismantled--my son needed the parts for a Chima vehicle... Enjoy!

    Yes, you can buy replacement pinions. I did this for a couple of trains using plastic replacements. Looking on ebay it seems that only brass ones are available at the moment.You could try http://www.ebay.com/itm/Pinion-gear-Replacement-Gear-for-Lego-Duplo-Intelli-Locomotive-Module-0-4-9-/201444974931?var=&hash=item2ee70e6153:m:mYQEmFvY5iw4Oeq_D7I26Cg (no affiliation with me). As for how to actually get the pinion off, you could try looking at: http://www.papa-mach-ganz.de/pdf/PapaMachGanz-LEGO-Duplo-Intelli-Lok-Zahnrad-wechseln.pdf. It is in german, but the pictures are useful. Good luck!

    Hi Jonathan, nice to see some more duplo ideas :-) My advice is to work quickly--before you know it, your daughter will be onto Lego...

    Mike--I tried to send you a PM, but it failed for some reason. If you send your details to me by email or PM I'll organise postage. Cheers, Peter

    Hi Mike, I think that component is actually an infrared transmitter or receiver. When you connect a smart carriage, it communicates with the engine via infrared. Will snap a photo when I get a chance... BTW presumably you are in Australia. If so, I'd be happy just to post you the circuit boards as spare parts--I suspect the chances of me doing any repairs on my engine are slim to none...

    Hi everyone, Mike: you didn't buy that train off ebay in Australia by any chance? I recall seeing an item for sale that matched your description. As it happens, I have an open (non-working) intelli-train somewhere on my workbench at the moment. The problem with mine is a stripped gearbox, so the circuit board may still be OK. If you like I could take a photo of the circuit board for reference. Legogal: I'm pretty sure that all the different types of Duplo track fit together. I think that the main problem is that with the different lengths making a closed layout can be a bit tricky. On the other hand, having a variety of different length straight tracks gives you more flexibility.

    Nice one Guy--I admire you dedication! Sadly I don't have enough crossovers to build these layouts, but it is interesting to see them and consider how they would work.

    That looks really interesting. Seeing the physical layout, it looks somewhat modular. I wonder what would happen if you duplicated everything to the left of the rightmost loop (i.e. everything from the right-hand points inclusive) and connected it in place of the left-most loop? Or perhaps replaced the right-most loop with a mirror image of everything to the left?

    Great, thanks for that--I'll pass it on.

    Nice work Guy. I have a feeling that a Turing-complete layout is only a matter of time... Robert--my son too has been playing with regular lego a lot lately. He's very keen on the Lego Cargo train set, but he'll have to wait for some time yet for that one. As for whether the kids whose train sets we've been playing with will appreciate the finer details of APR, APV and computational duplo track layouts, who can say? However, the 11-year-old brother of my son's friend was rather taken with the binary counter layout. He is an aspiring coder, as well as a lego fan, so the whole concept was rather appealing to him. I've been thinking of a couple of new symmetrical Duplo track layouts that should be APV. When I next have the time (and the floor is free of lego) I'll try to make another video.

    Thanks for that Guy

    Thanks :-) It was quite a satisfying layout, especially with the train visiting all parts of the track without any intervention. I'm trying to think of my own (non-computational) layout that also visits all points. Ideally I'd like to come up with something symmetric--I'll post another video if I come up with something interesting.

    Hi all, I've successfully made the 3-stage binary counter. I've put together a video which shows it in action: Enjoy :-)
