    Love the subject you chose for this moc. Fantastic execution. And I would be very happy if moc like these continue to be posted in this section of the forum.

    The only set I had fun rebuilding is 8043. A lot to learn from that set. But in general I find building from instructions quite boring.

    This is one by Sariel that makes tracked vehicles steerable, it also controls speed/direction. http://sariel.pl/2009/04/8879-power-functions-speed-control-remote-modified/

    Lovely idea and well executed :)

    You may want to take a look at a Youtube video about different kinds of LEGO track suspensions I made some time ago:

    Some non-vehicle technic MOCs with cool mechanisms that I was impressed by: Vuurzoon's Lego Windmill 't Nupke: Grohl666's Lego Technic Kinetic Horse Sculpture: Jack Streat's guns and others like it. Though not suitable for small children. But the mechanisms sure are pretty cool.

    If I quoted you by mistake my apology. That was indeed not my intention. It is strange though because I don't see any quote box in my original comment.

    [MOC] Neo Blacktron 1 spaceship

    Kelkschiz replied to Ikonhero's topic in LEGO Sci-Fi

    Love that build. Do you have any place where I can follow your work or see more of your MOCs, something like Flickr?

    Supercars are the cars which, when you see them in real-life, you can't stop looking at it, often accompanied by a dropped jaw. For LEGO car models more or less the same applies ^^.

    When I buy an old set, I take it apart. Clean if necessary. Then I sort the parts. All the parts I don't need I upload to Bricklink and the rest of the parts join my collection, yey!

    Absolutely something I looked at at the time but none of the existing LEGO sails come anywhere near what I would like to see on a ship that actually has to sail. My own LEGO sailboat has ripstop nylon sails which is a material that is well suited to be used in sails. I would wager that making a similar sail out of LEGO sails wouldn't produce a sail that works half as well. I am afraid that I am kind of a perfectionist when it comes to such things.
  12. Kelkschiz
    Absolutely, a fully functional sailboat would be awesome. Once I tried to submit something like that on LEGO ideas, but the they won't accept custom sails and a sailboat without sails...

    Hey guys, this is my latest MOC. Been working on this MOC for a long time. Apart from it's appearance the biggest difference with its predecessor is the integration of an EV3 in the turret. That took quite a bit of work because the EV3 unit and the Mindstorms motors are so much bigger than the PF ones. Had a hard time building a turret that was roughly the same size as the previous one. The main reason for wanting to include the EV3 was because I wanted the gun barrel to be self-stabilizing, that is keeping its elevation regardless of the elevation of the hull. Its implementation can be improved upon. While it does its job adequately, the mechanism should operate faster. At the moment it works like this: take measurement → compare measurement with previous measurement → adjust the barrel accordingly → take new measurement, etc. This cycle can take upto 10 seconds to complete, depending on the difference in elevation, which is too long really. But this time around the main objective was to get it working in the first place. It was my first attempt at making a program for the EV3, which was more difficult than I had expected. I have some ideas on how to improve it, but that will have to wait for a bit. Now I've made videos about LEGO tanks before. However this one is a little different because I also set out to include something of a story in this video. It's also my first video where I had multiple people collaborating with me on different parts. That is besides my best friend, Depipro, who has helped me before. Hope you will like it.

    Hey guys, Just want to let you know that I made a simple video about the technical side of my Mark 7 LEGO Tank. I also mention several Eurobricks members in it who helped me in some fashion. Also if I didn't mention you by name doesn't mean you didn't help me, because there are just so many people here that manage to inspire me. For instance oracid and Alasdair Ryan, I didn't mention you in the video but you for sure had some impact on what I chose to talk about. Also for those who haven't seen my LEGO Tank Warfare video, I made a shorter one that focuses on the second half of the video where all the action is.

    Again there are many ways to make a rotating turret with Technic LEGO but some often used parts are: http://alpha.bricklink.com/pages/clone/catalogitem.page?P=18939c01#T=S&O={} http://alpha.bricklink.com/pages/clone/catalogitem.page?P=99009c01#T=S&C=86&O={"color":86}
  16. Kelkschiz
    A torsion-bar suspension is easy to make, cheap and functions well for nearly any size of tank. The other questions are very difficult to answer because I don't know what kind and how large a tank you are imagining to build. Lego tanks vary hugely in size and functionality.
  17. Kelkschiz
    There are a million and one ways to build an RC LEGO tank, so please take everything I say with a grain of salt, it all depends. I made a video about building my first couple of RC tanks, you can take a look at it here: https://youtu.be/LAVb-w7TWC0. I have also made several tutorial videos about this topic (see my channel). With regards to the motor, pretty much what Tommy said. The amount of motors depends on what kind of functionality you want to tank to have. For driving I would get 2-4 Medium, Large or XL motors. For turret rotation, gun elevation and shooting you are probably best of with some Medium or Large motors. I think the best way to buy those is through the official LEGO shop. You can just order the motors you want. For controlling the tank I would get some Sbricks. Ow and finally, I would just order the rest of the parts you need through bricklink instead of getting a specific set, eventhough that is what I did when I started. In hindsight I would have been better off if I had just bought the parts through bricklink.

    Thanks :)

    I see what you mean. The width I use is due to my focus on function. With my builds I follow the "form follows function approach". I always try to make the diameter of the turret ring as small as possible, and that diameter + the width of the tracks = the width of the tank. The diameter of this tank had to be slightly wider than the previous tank to accommodate the significantly larger EV3 servos. After that I could still have decided to make the tank longer to give it a sleeker look. However the length of the tracks is a crucial factor in the road-handling characteristics. The longer the tracks, the more friction the tank has to overcome when traversing. Considering that one of my main goals is that it actually needs to perform well, even on rough terrain. Add to that the fact that LEGO builders are severely limited in the available engine power that LEGO offers, I felt I had to compromise where the length is concerned. It may be that at some point in the future that will change. For instance when I learn to build even more compactly, lighter and/or I get access to more powerful motors. I just wanted to make clear that it is not as simple as deciding how wide the tank will be.
  20. Kelkschiz
    Why do you think my tanks are too wide? I have already build the chassis for my next tank and it will indeed have fully covered tracks.
  21. Kelkschiz
    Ah I see :)! Actually the Mark 1 and 2 were nothing special... and that is being very kind. You could also say that they were ugly as hell :P. I started making pictures when I got to the Mark 3, which I was pretty happy with... at the time. But looking back at it (https://www.flickr.com/photos/33425520@N07/albums/72157645136481323), lets say the Marks have come a long way.
  22. Kelkschiz
    You do realize that you just called my little baby too fat, don't you!!! Haha, just kidding . V1, what is that? Thanks! Actually your first sentence is a pretty good description of the program I made. I don't think it would be too difficult to make it so that the barrel never overextends. That would actually be a natural extension of the current program. At the moment things get messed up when the barrel overextends. In that case the program doesn't "know" the position of the barrel anymore. Where is the gyroscope sensor in your example? It's attached to the gun barrel right? That's the only way I can make sense of what you are saying. In my situation it is attached to the turret. I did it like that to enable the user to manually elevate the gun barrel without the program getting messed up. The barrel will just elevate and for the program nothing is changed. When the tank moves and the inclination of the turret changes then the gyro sensor will notice and will try to compensate so that the barrel is restored to the inclination it was set to. Fixing the gyro sensor to the gun barrel would have a lot of advantages. But then it would become very difficult to deal with manual changes in elevation of the gun barrel. I have not been able to find a way to remotely change the elevation of the gun barrel and at the same time figuring out a way to tell the program that it is a user input instead of a change in inclination of the terrain. That is why I chose to attach it to the turret instead. I think Ideally you would want a system with two gyro sensors, with one attached to the turret and the other to the gun. But Unfortunately I don't have two sensors.

    Wow, very cool build, love it!
  24. Kelkschiz
    I think it is great to have people develop 3rd party solutions for the LEGO PF system and it would be good if the Sbrick got some competition. I wish you guys all the best.

    In my experience it is not the government funded schools who have the big budgets, it's the privately funded schools who are able to afford the expensive stuff. Public school often don't even have a budget to hire decent teachers. But perhaps its different in the USA.
