After 7 months of engineering and building, I'm proud that I can present you my new video! In the video you'll see three coal trains riding around. They can load at two silos and unload at the main terminal. The unloaded coals are delivered by conveyor belts and an excavator to the loading silos, so a continuous loop is possible! The unloading part is the most complicated part of the structure: pneumatic cilinders will push a conductor to the bottom of the wagons, where also a conductor is located. These conductors power motors in the wagon which open a hatch in the bottom of the Lego coal wagon. The coals drop on a conveyor belt and are transported with other conveyor belts and an excavator to the silos. It's all automated by 6 Arduino controllers (including the arduino that controls the passenger trains). I cleared out the living room (GF was away for a few days, as planned) with a friend of mine and after 12 hours of setting the whole thing up we could finally begin with running some trains and commission the whole thing! Obviously the whole thing didn't work at once, so a hilarious fails-video is on the way too. Enjoy, share and let me know what you think of it!

Hi all, Im so glad to present my MOD of the 21108 Ghostbuster car with custom SMD LEDs controlled by an ARDUINO UNO. In the process no Original set pieces was modified, but 10 vault pieces were modified and glued in order to fix the leds and pass the cables trought the model. And the best way to see it, a little demostration video. PS: The process of soldering the SMDs and cable routing was a nightmare, but the result deserves it. A small update with pictures Full model with a street display (arduino housing included) Detail of the instalation of the SMD leds, Front lights (modified round bricks and some kragel to fix it) Upper lights (plate with right holder modified and round plate kragelized) Upper principal lights (no kragel or modification, just the SMD led placed and fixed with 4 round plates below the cheese slopes) Some details of the cable routing Detail of the soldering plate with all cables and resistances soldered Arduino housing and cables for conect all lights Hope you enjoy it

MOC in progress: beer/soda from fridge serving robot
AlmightyArjen posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I came up with the idea to build a robot that can get me a beer or soda from the fridge while I'm watching Die Hard... I'm building it completely from Lego Technic, mostly studded. I use my own designed electronics to control the motors, pneumatic valves and read out the sensors. It saves me hundreds of Euro's by not using the NXT platform ;) Next to that: the NXT platform is not as flexible as other programming platforms. I have been busy with it for a few months now and there were some problems to be solved so I've divided "the project" in smaller goals: 1. Get the rover over a bump in the living room (success!) There's a nasty bump between the kitchen and the living room. Since the robot is going to be well over 10kg, I had to find a way to get it over the bump. The solution was to use caterpillar tracks (the robot needs to be able to turn around its own axle) with on top of that studless beams for extra grip. I've put some filt on top of the beams so my wooden floor doesn't get damaged. Video 1: 2. Make the robot move sideward to be able to position itself (success!) Not being sure about the precision of the tracks, I need the robot to be able to move sideward for positioning itself in front of the fridge (to be able to grap the handle). I designed a pneumatic system with 8 pistons that push down 8 wheels, that lift up the robot just a bit. That way the robot can move sideward, which is impossible with caterpillar tracks. As you will see in video 3, the accuracy of the distance sensors is good enough that the robot doesn't need to move sideward. If the system isn't needed when the robot is completed, I could remove it. Video 2: 3. Indoor navigation: make the robot find its way to the frigde, couch and back (success!) Using 4 ultrasonic distance sensors and a digital compass, I make the robot navigate around the house. It works just perfect! Video 3: 4. Think of a way to make the robot open the fridge I'm working on this one now. This one is by far the hardest to complete. I have already a pneumatic system that can grab the handle and open the fridge a few centimeters by setteling itself against the fridge. As you know: sometimes the fridge door is a bit stuck and you need some force to open it. Grabbing the handle and just drive backward doesn't work because of the height of the robot. Right now I need to find a way to open the fridge door further and move the robot to the inside side of the door. This is tricky and I haven't figured it out yet. If you have any suggestions: let me know! Further things to do: 5. Make the robot able to grab a can of beer/soda 6. Make the robot do the whole thing: getting out of hibernation, getting a beer, bring it to the couch and go back to the hibernation spot 7. Design an Android app that communicates with the robot through Bluetooth so I can order a beer from the couch -
Arduino and PF Motors

Hello! My Rescue Helicopter (9396) is about to be delivered ( ) and I have this idea to put enormous amount of LEDs in it. I have a plan to use Arduino to program proper blinking sequence. I was thinking about mounting also 2 M-motors to motorize rotor and functions. I would love to control them via Arduino but I do not have an idea how to connect motors in a proper way. Has anyone ever done it? Thanks in advance for any tips!
