    Based on the pictures we have there are 4 x 4 = 16 different gears. It could be that the secondary gear unit has only two different gear ratios. that way we get 4 x 2 = 8 different gear ratios I would love a @Blakbird render of this gearbox PS: What official video? Seems i missed something.

    I guess you mean to watch it when he releases it? Or have i missed him posting it on youtube?

    That's awesome What's the best source for the current activities of @Jim, @Sariel, and the rest of the gang in Billund? Can we expect more to come?

    I'm really curious for Jims review. I want to see how they realized the geneva mechanism to drive the second gear selector.

    My last experience with Mindstorms was the NXT so my questions might be outdated: - Have the considered native support for written programming languages? If i remember correctly one had to change the firmware and use a custom IDE - What sensors would they like to produce/will never produce? I would love a force-sensor. (I know you could build one with the touch sensor and a spring) - What limits the number of Out-/Inputs? - Regarding smartphones, modern consumer electronics have a very short lifespan on the market. How is this taken into account during development? Is good, is it bad for them?

    This is incredible. You managed something i always thought impossible: LEGO with the performance of a real RC-Car.

    Me too, but @Carsten Svendsen is right. more teeth provide a smoother and more efficient transfer of power. If you're afraid of slipping gears, i suggest gearing up before the bevel gear set. This method did wonders to the drivetrain of my bucket wheel excavator.

    This seems to be a powerful mod. unfortunately worm gears have a tendency to become really inefficient when they transmit a lot of torque. generating the same ratio with straight or bevel gears would actually be more efficient i.e. more powerful. I'm really interested to see the slewing. You're losing quite a lot of leverage by not using the outer gear teeth. I'll be watching with interest

    This is incredible Thank you very much for sharing!

    Incredible Looks like a fun model in any way, the poses show a lot of character

    It is awesome that he used the conventional battery box. I've got a lot of them from Technic sets. The LiPo box isn't contained in any sets and fairly expensive. But then again, he used the switch, also a relative uncommon part

    Exactly. A longer tube only changes the dynamic behaviour of your system. Waiting long enough, the pressure on your pistons is the same as with short tubes. The main difference comes from the dynamic resistance a long tube has, so your system will react slower. Also, the elasticity of the tube means that you will need slightly more air for the same movement as the tube will expand with pressure. If you switch early enough, you shouldn't have any problems :-)

    I'd say drop the engine. This is clearly a performance model, not a display model. Except is was your aim to create a "realistic" model, then it needs some kind of engine

    This is great to hear. I'm glad i could help to improve this incredible MOC

    Did you orient the joints correctly? This influences the smooth motion quite a lot:

    This is great. I haven't seen this color since 8257. And never in such a fitting combination with red. I'm eagerly awaiting a picture of the assembled model.

    Oh man, i remember building that robot arm, then simply copying the demo-code and marvelling at all the intricate movements. I think the instructions were hidden somewhere in the software. How are you programming your RCX?
  18. schraubedrin
    This is an incredible build. Do you have any pictures of the internals? I'm really curious how you managed to power all these fans.

    Another point for @Didumos69's list should be: ... make sure the bevel gears are supported on the rear side (as is the case in his example. bad would be to replace the 20t gear with the flat version and a bushing) To reduce unnecessary friction in @Didumos69's example, i would replace the Technic Pin Connector Hub with 2 Pins with a Technic Axle and Pin Connector Perpendicular 3L with Centre Pin Hole. This way the output-hole is guaranteed to be coaxial to your output-axle.

    24: 10 8: 6 19: 4 2: 3 10: 2 12: 1 I really like this contest. Voting was difficult as there were entries in completely different directions. Some focused on design, some on mechanics and some on presentation. I wish i could give more points to more contestants

    @Blakbird, what's your timeframe? Do you want to give it some time for the word to spread? Maybe there's a rich AFOL in Dubai wanting to get your whole collection? I think you could push the museum-idea further. Maybe there is one in Europe willing to buy all your MOCs, including shipping. Or maybe even LEGO themselves. But those certainly aren't fast-selling options. I'll post this thread in the subreddit, there are some interesting personalities on this website

    That's a really cool project. Have you tested the gearbox under load? I'm anxious about the 16t input gear not being directly braced to the following gear. Also the 24t gears on the tracks seem like they could work themselves loose pretty quickly.
  23. schraubedrin
    That's really sad to hear. I always hoped to come to America one day to visit "Blakbirds Technic Museum" On a related note @Blakbird: Have you considered asking a museum to buy it from you?
  24. schraubedrin
    Those are great tips. [OT:] Have you ever tried to make a clock with a remontoir? Like i tried to do here (i hope its okay for me to post my own thread ): Is the 40tooth gear so efficient because of the small angle its making between each tooth-jump? If so, have you tried making an escapement based on the new 60 tooth turntable?

    To save you some hassle, here's my try of explaining it: Make a list of your Top 5 entries. Then copy the point values from another voting post or the explanation point. The difficult bit for me is choosing the entries and their order
