    since the partslist is already available, you can probably figure it out ;)

    @Gioppa, it could have been better, I like the idea though! But apart from that, they made it just too easy for me this year :)

    This is the newest LEGO inside tour set: the LEGOLand Billund small gauge train. Interesting articles on the train: Brickset 1000steine (in German) NewElementary Flickr images Looks very nice in my opinion, we see that they are still making tracks like the mining series (based on the old 12V tracks, without the notches). I think they did a great job, too bad that it will be very hard to get for most of us train fans!

    motherboard? you mean circuitboard, it is not a PC you see. They are 1$ at bricklink so...
  5. JopieK
    interesting idea!
  6. JopieK
    too bad :( looking forward to the new project!!!
  7. JopieK
    it could help if you can provide the size of the brick, the colors, etc. apart from that, a circuitboard ≠ motherboard though a motherboard == a circuitboard ;) maybe this one? http://www.bricklink.com/catalogItem.asp?P=55206c01

    a very great job indeed!

    Very nice indeed!

    Alas ;) it is a good tip though for other Windows LDD builders.

    no need to say sorry, SNOT is an AFOL 'standard' of course if you look at it from an engineering perspective.

    we use an Arduino (custom board) at my school to control trains. It has a dedicated motor driver chip, support for front/tail lights and an XBee header. Atmega328 µC. Fits >within< 4 x 8 studs. it is about 1 stud high, so fits into a lot of trains. Power: 3.3V (of course the motor might need more volts. Much better control than LEGO PF (8 bits instead of 3).

    depends on what amount I guess ;)
  14. JopieK
    well, there were quite some 4.5V trains, so it would be better to try and explain what train it is!
  15. JopieK
    I guess you are right, but it depends on 'all', of course most modern trains will, although the high voltage control will be probably also different from low power version. These also have the "eeeeee" sound: http://en.wikipedia.org/wiki/NS_VIRM
  16. JopieK
    Well, they all use electric PWM motor controllers ;)
  17. JopieK
    well, that is why people like us reproduce stickers, then you can use affordable stickers and keep / replace the originals

    there is an issue with latency, but... I have used latches to solve that problem, next railbricks will be a bit basic, but... the issue after I hope to discuss that as well. Bluetooth is also a good idea especially Bluetooth Smart, I have quite some experience with that for an other project.

    you are aware that chromebricks is already very well known for this?, so he already has a large number of customers and you are doing exactly the same, so I'm just saying...

    The LiPo from LEGO is just too great to ignore. It is so solid and well protected! we use it at school and believe me students have been harsh on them. you could use a protected power pack like these though: http://www.dx.com/s/18650+3.7 you will need separate chargers for them, but they are well protected agains shorting etc., only they are quite large (larger than AA.

    a better option is using RFID, I have done that and it works well.
  22. JopieK
    looks very nice indeed! only misses a volvo logo ;)
  23. JopieK
    very nice work! gratz on FP too!!! and... you deserve it!
  24. JopieK
    Very nice job of cop mike, he is missing some stickers though ;)
  25. JopieK
    why not? LEGO wants customers to be satisfied is my experience! just ask customer service Jody, they will help you out, I'm sure!
