  1. Hi all, a couple of weeks ago I presented some experimental results of comparing the relative friction of 4 different motion transfer methods - 16 teeth gears, 40 teeth gears, a perpendicular axle, and a chain. I have now published the build instructions for anyone wanted to run their own experiments. Please post any results if you do.

    Brain in a vat

    Hi! Today I've made a lego interpretation of the well-known thought experiment. Are you sure that this topic isn't simulated by the computer while your brain is peacefully floating in a vat? Brain in a vat by Argos Green, on Flickr Thank you!
  3. Hello everyone, my name is Ivo and this is my fist MOC. I've returned to Lego after 20 years when I started playing again with my son. He is now almost 5, and we're building every day together. I've started this project with literally zero brick (I didn't want to steal parts from our playing sets) and zero experience, so it took my about 14 months of planning, acquiring parts and building it. There are many things am not fully satisfied with, but I've had so much fun making this project and I guess that's what really matters. I've tried to recreate a scene from a German WW2 mythical "Die Glocke" project. Allegedly, die glocke was a top secret German wunderwaffe or wonder weapon project with purpose of changing the course of war. There are many speculation of what actually the glocke device did once after it was activated. There are many theory - biological weapon, anti-gravity device, even torsion field generator that can alter time and space. But am not about to bore here with technicality speculations, especially because the device was never found after the war, and there is no real proof of anything about its function. Although some elements of my project are trying to be as much as it can be called authentic (experiment location, glocke device look, bussing nag 4500 crane truck) almost everything is purely fictional. Thanks for stopping by and of course comments and critics are always welcome.

  4. Good day! This was an experiment for me ,I combined system and technic bricks in one model, something I never done before. This resulted in a failed replica of the original, but served as a good lesson to me. In the last three years I haven't built anything from system, and my pre-2013 creations were really bad. The model I tried replicating was a Vapid Police Cruiser from GTA IV videogame. Fortunately there's a whole wikia dedicated to GTA ,so finding resource information was very easy, there even exists an image of the police livery . For those not familiar with the game , here's a picture of how looks the car: And this is how ended looking mine: I see a lot of errors, most of them are because of my limited resources but others are because I have very small experience building bricks. On a bright side I managed to fit these functions: Drive and steering Working steering wheel Detailed dashboard Opening hood(bonnet) ,trunk and doors Stickers Working front lights Adjustable seat ^probably the most boring underside you have seen in your life^ Bricksafe I haven't made a video yet, I have planned something unusual I hope my camera will be able to film like I want to. LDD is at 90% 100% I hope this isn't too bad to post here , please post your recommendations about the combination of both building styles , because the connectors in system are killing me . I promise the next time I will post something better than this! Vote in the poll, it will help me making better creations :)
  5. Some time ago this thread appeared, talking about a substance called "Bullfrog SNOT": After some initial confusion (is this some sort of new building technique?), I learned it was some sort of substance model railroaders could "paint" onto their wheels to add traction. I was pretty sure that it would just be worse than an actual traction tire, and forum posts reviewing the substance seemed to agree with me. The train wheels Lego makes both feature a groove for traction tires already anyway. However, I had been considering a couple things I wanted to model where the correct wheel size is closer to a Big Ben Bricks medium wheel. I didn't trust myself to cut a groove into the wheels without access to proper machine tools, so I thought I'd try the "painted on" traction tires. One key issue, however: I'm kind of a cheapskate, and didn't want to spend $25 on a tiny container of stuff to find out how well it worked. Furthermore, if it did work, and I posted about it, forum members who aren't from the only country to put men on the moon might have difficulty accessing the substance (although Tenderlok seems to have managed somehow). Time to find a substitute. Whatever I found needed to have the following properties: Increase friction (adds traction). Can be applied in a uniform layer. Transparent, so it doesn't affect the appearance of the wheel it's applied to. What has these properties, and is readily available? Urethane caulk from a hardware store! However, caulk is far too thick to apply evenly in a thin layer. The packaging bears the words "easy soap and water clean up"; I took this to mean that I could thin it by adding a small amount of water: I then used a small brush to apply this onto a clean spinning wheel to get an even coating: I left the wheel spinning for about half an hour for the thinned caulk to dry. Here's what it looked like afterwards: I built a small test vehicle and ran it on a figure-eight for about half an hour (so as to test it going around turns both ways). This was the result: legoman666 is remarkably prescient... Pressing down on the test vehicle suggested that the painted-on tire had a bit less traction than an actual traction tire, but traction seemed to remain reasonable after a half hour of running. I wanted a more thorough test though, so Commander Wolf installed the modified wheels on his QJ and had it pull some long cars for most of a BayLUG meeting. The result: This stress-testing caused the tires to wear off. I'm not sure if that's a property of the substance (did I thin it too much?), or perhaps the underlying surface being too smooth for the caulk to adhere well. More testing is in order...
  6. We just published an interesting article on whether LEGO products have become more violent. What do you think? Here is the summery of the article: "Although television, computer games and the Internet play an important role in the lives of children they still also play with physical toys, such as dolls, cars and LEGO bricks. The LEGO company has become the world’s largest toy manufacturer. Our study investigates if the LEGO company’s products have become more violent over time. First, we analyzed the frequency of weapon bricks in LEGO sets. Their use has significantly increased. Second, we empirically investigated the perceived violence in the LEGO product catalogs from the years 1978–2014. Our results show that the violence of the depicted products has increased significantly over time. The LEGO Company’s products are not as innocent as they used to be."
  7. brebo Hi, I have launched a KickStarter (crowdfunding) campaign for a simple, low cost and intuitive system to invent and recycle electronics using Lego. Have a look [removed url] Let me know what you think. Thanks!
