[MOC] Sequencer Music Machine
Fissl posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello! I just joined the forum, and now i want to introduce myself and the latest MOC i built ;) It's a programmable sequencer playing a little song on a KORG monotron Duo (an analogue synthesizer) and a MakeyMakey what sends midi-signals to an audio-software (in my case logic) to trigger drum sounds. But I'm not very good at explaining, so take a look and tell me what do you think! Cheers, Fissl -
The Cuusoo support page of LEGO GBC 8 is finally published!;)
PV-Productions posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi there, I previously posted the LEGO GBC 8 but now, after a week, the supportpage of the project is finally published. So, support the project if you want. Thanks. Click here to download the building instructions on my website! Click here to watch the video on my website with more information about mechanisms, programms, buildinginstructions, music I used, etc etc : Here's some information about the LEGO GBC 8. To download the building instructions and watch the pictures, please visit my website: http://pv-productions.com/lego-gbc-8/ Bron: Geek.com This is not GBC builder Philip Verbeek’s first outing with the concept — he’s on his 8th GBC build. Some of the past ones have included ball launchers, ramps, elevators, grabbing claws, and more. This time Verbeek has gone for a very ambitious build consisting of elevators, moving ramps, and a crazy undulating bridge. He’s also incorporated Lego NXT that allows him to track data about system performance and control the whole thing with an Android app. This new GBC consists of about 2,000 pieces, which is fewer than some previous builds. The contraption is powered by 2 XL Legomotors — one for all the modules, and one for the airpump. The mechanical energy from the motor is transmitted to most of the modules via gears or a network of strings woven through the blocks. Possibly the coolest aspect of this GBC is the Sinusoid ramp at the beginning. Watching it undulate while suspended by a network of strings its kind of mind boggling. It must have taken a good long time to get it timed correctly. Verbeek has also been kind enough to give us a walkthrough of the design. You can follow along with the gallery above to see each module up close. Stop-go mechanism 1: Stops balls and let them go by at the right time. Sinusoid: Moves the balls by making a sinusoid motion. Stop-go mechanism 2: Stops balls and let them go by at the right time. Elevator: Lifts the balls to a higher level. Every time 3 balls can fit in the cabin. Bridge: Leads the balls of yellow tower to the blue tower. When the elevator is down the bridge will go up and when the elevator is up the bridge is down. Stop-go mechanism 3: Stops balls and let them go by at the right time. Vertical pushers: Pushes the balls in a vertical way up. Color sensor: takes measurements of the balls. Ball pump: Pumps every time one ball. A new ball takes a place beneath another ball and then pushes them up. Android app: Controls the LEGO GBC. If you think you have the time and patience to assemble your own GBC with near-clockwork precision, Verbeek has made the plans available to download. It’s also on Lego’s Cuusoo page, if you think it’s worth supporting. Maybe Lego will finally make one of the GBCs a reality? You can also track Verbeek’s projects on Facebook and his YouTube channel.

LEGO GBC 8 + Building Instructions (5 modules - 2 motors)
PV-Productions posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi there, Click here to download the building instructions on my website! It has been a while since my last GBC. But I have made a new one with new modules in it;) Click here to watch the video on my website with more information etc.: Here's some information about the LEGO GBC 8. To download the building instructions and watch the pictures, please visit my website: http://pv-productions.com/lego-gbc-8/ This time I used over 2000 LEGO pieces. I used 2 XL motors. One for all the modules and one for the airpump. I also used the LEGO NXT to control the LEGO GBC with your smartphone, so you can wireless turn it off and on again. You can also control the GBC with a mechanical switch. I also used the LEGO NXT for measuring data for more details. So now you can see the balls that have passed by, the average amount of balls per second and a clock to see how long the GBC is running. The mechanisms and functions, which I used, do not all have names. So I named them again by function. 1. Stop-go mechanism 1: Stops balls and let them go by at the right time. 2. Sinusoid: Moves the balls by making a sinusoid motion. 3. Stop-go mechanism 2: Stops balls and let them go by at the right time. 4. Elevator: Lifts the balls to a higher level. Every time 3 balls can fit in the cabin. 5. Bridge: Leads the balls of yellow tower to the blue tower. When the elevator(4.) is down the bridge will go up and when the elevator is up the bridge is down. 6. Stop-go mechanism 3: Stops balls and let them go by at the right time. 7. Vertical pushers: Pushes the balls in a vertical way up. 8. Color sensor: takes measurements of the balls. 9. Ball pump: Pumps every time one ball. A new ball takes a place beneath another ball and then pushes them up. 10.

NXC: MotorOverload always returns false
AVCampos posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi all! I'm programming a robot that has limited travel on one of its articulations. I don't require precision on its position, just that it stops the motor as soon as it hits the limit. NXC has the MotorOverLoad function, which appears to do exactly what I want... however, it always returns "false" even if the motor is completely stalled! Digging a bit, I found that MotorOverload is actually a shortcut for one of the fields of GetOutput (like "GetOutput(OUT_A, OverloadField)"). Checking the field's documentation, I see that, for it to work, I need to set the motor according to numerous parametres... but, after setting them, I can't get the motor to actually run! This is what I wrote to get the motor running, while enabling MotorOverload: SetOutput( OUT_C, RunStateField, OUT_RUNSTATE_RUNNING, OutputModeField, OUT_MODE_MOTORON + OUT_MODE_REGULATED, RegModeField, OUT_REGMODE_SPEED, PowerField, power_C * d); (power_C and d are variables I defined) If I use the normal "OnFwd" instead, the motor is never stopped: if(MotorOverload(OUT_C)) { Stop(OUT_C); } What could I be doing wrong? Thanks in advance! -
I am thinking of selling one of my black NXT bricks. It is a limited edition of 1998 made. I did not buy it as a collectable, I just thought it looked interesting. I used it one or two times, but not much at all. The certificate is a PDF that the buyer can put their name on and print. I have seen prices all over the map from $180 to $280. Any interest in the Black NXT brick for $150? For $150 I will pay packing and shipping to a USA address. I also have a grey NXT brick that I will sell for $85. For $85 I will pay packing and shipping to a USA address. Or both for $200 and I will pay packing and shipping to a USA address. Any interest? Andy D

NXT Bluetooth "!Receive Message"
Jim posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I have moved your question to the Mindstorms Programming topic. Original Question -
On Rebrickable, Timothy Endersby posted his Lego Mindstorms NXT Double-Tracked Tank. It is surprisingly capable. His description on his :"Double-tracked is my attempt at a robust tank using the rubber treads. I used the rubber treads instead of the hard plastic treads since they have much better grip (and I have no plastic treads). This worked very well. The only down side to this is that there was no suspension. Also, the gears connecting the front and back treads would often catch on the ground. Overall though, I think this could outperform almost any other Lego tank the same size with hard plastic treads." He created 10-page PDF Building Instructions and a Zip file containing LDraw building files. See 6 pictures on his Mindstorms Podcast website. -
NXT 2.0 bluetooth not connecting?
newhorizons posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
recently the bluetooth compatibility on my mindstorms NXT 2.0 has stopped working, the mindstorms porgram now does not recognise it as a bluetooth device, it says "unavailable". I run mindstorms v2.0f5 on a 2009 macbook (wich I recieved in 2011) the computer runs on 10.8.3 mountain lion and the NXT runs on firmware 1.31. I have established that the bluetooth connection on both machines (laptop and NXT) as I can in fact pair the two devices. the problem is the NXT Retail program itself, it just does not connect making it useless, so there must be some patch to the program. I have attached a picture of the window in question, when I hit "scan" essentially nothing happens, it appears to be searching but within a millisecond the screen returns to its previous state (the state the picture shows). I watched it in activity monitor when I hit scan and the program did nothing, nothing new came up. Please respond with any ideas, questions or even possible fixes, I really need help here! -
The Reaper 4 x 4
Doc_Brown posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello everyone! I'm proud to show my latest MOC... THE REAPER This model is based on Tim Cameron's "Showtime" and other similar Rock crawlers. The chassis utilizes NXT motors geared down 3:1, and one servo for steering the front wheels only. The NXT motors are connected using adapters that allow connection to regular PF elements. This project started out as a "quick" experiment that soon got out of hand!!! I enjoyed trying out ways of joining liftarms and seeing what shapes I could get out of them. Things that I'm not too happy with are the shortness of the model, and now that I have found some better pics of Showtime I can see it should be 3-4 studs longer, and lower too. The seats were far more leaned back, but due to the rear motor needing more clearance I had to pull them forward making the cab a bit cramped. LOL As for performance, I was amazed, The Reaper will easily go up 45 degree plank of wood, that is quite smooth with no major tweaks. Turning isn't the best, but that is to be expected with no diffs; and I tried to tune it to a nice balance of turning and NON wheel tearing. This crawler has no gear grinding at all, and I am very happy with the new type 2 8t. :thumbup: also I rigged the PF lights to the steering so it kind of flashes when steered! Edit: The shocks were made from combining Unimog and old bike sets, just to keep it black. Weight is 1.320 KG. After I have made a video (prob next week, Wed) I will reuse and tweak this awesome chassis, and hopefully make something a little lower. Please feel free to comment, and ask any question's. If you would like a particular pic please ask soonish as I have the lights set up hahaha. Thanks for looking. -

It was rather simple to build, but the turning mechanism took me awhile to figure out.Here is a short video I made: I am almost finished with my GBC layout, so be looking for a post about it soon! I just noticed I accidentally spelled "Mechanical" wrong in the title, sorry. -
My NXTLOG Creations
pluto7443 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Well, I posted a lot on NXTLOG before I ever discovered EuroBricks, and so instead of reposting all of my creations, most of which weren't that great anyway, I decided to just summarize them here and provide links to each of the projects. So, here goes. I don't have any pics of my first creation on this computer, so here is just a link: http://us.mindstorms...c4-65e19addb8b4 X-1 Speed Boost Link: http://us.mindstorms...01-2421bc026580 X-1 Speed Boost Mk.2 Link: http://us.mindstorms...43-2f3d841fe7b2 X-2 Black Scepter Link: http://us.mindstorms...01-04630d644675 X-2 Black Scepter Mk.2 Link: http://us.mindstorms...01-b4874ff0b925 ULTRA (Ultimate Lego TRacked Attacker) Link: http://us.mindstorms...70-94ef06375900 X-3 Kilo-Carrier Link: http://us.mindstorms...ed-ef3ee2d5725f Z-1 Heavy Explorer (First Wheeled Vehicle) (Sorry, can't find any pics on my current computer of this one either.)

MOC: Metro Station with NXT controlled sliding platform doors
Esben Kolind posted a topic in LEGO Train Tech
Hi, At the recent Lego World 2013 in Copenhagen I displayed my model of Islands Brygge Metro Station including NXT controlled sliding platform doors. This model is the fourth in a line of trains with automatic sliding doors, that I have built over the last years (version 1, version 2, version 3). I have compiled a short video to show all the functionality including some "behind the scenes" footage: The NXT controls the following: Output 1: Running the train on the inner loop (9V) Output 2: Running the opening mechanism for the three sets of platform doors and three stes of train doors Output 3: Running the elevator Light sensor: Stopping the train at the platform (accuracy: 1 stud) Distance sensor: Detecting the lower position of the elevator (dynamically calibrating the elevator cycle) Touch sensor: Detecting the outer position of the opening mechanism (dynamically calibrating the cycle) In addition, there is a 9V metro train running on the outer loop and PF lights on the platform wall and over the platform door. Some images of the station, which was part of a bigger display of Islands Brygge, a central neighborhood in Copenhagen: After moderation, more pictures can be found here. The station is modelled very closely after my local metro station, though I have reduced the number of opening doors to three sets. Here are some reference pictures: I am looking forward to your comments. Esben -

LEGO Education - SmartCity
laix posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hey, I was really busy over the last months and wasn't able to build any models in my free time. But luckily I get paid to build at work where we made several projects over the last year. One of the major tasks was to build a model to display several options to generate and store electricity. Some of you may are familiar with Isogawas great GBC "smartcommunity" and we wanted to transform this idea into a real working power generator. Therefore we used ten Renewable Energy Add-On Sets (9688) and four NXT 2.0 to control everything. The video is in german, an english translation will follow soon, as well as a pictorial overview on my blog. Hope you like it. Best regards, laix -
Mindsensor LineLeader
martinnygaard posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi all LEGO lovers! I've bought this Mindsensors LineLeader sensor some weeks ago. But i'm not really satisfied with the result. The veichle zig-zag a lot, and i saw some videos of this sensor at Youtube (like Xander's) but my result is net even close to his. A picture and a video will come soon. my question is; What is your experiences of the sensor? is there a minimum wheel size, for making it work properly? maybe the sensor has to be a minimum distance from the driveaxle? Hope some of you guys can help me - need it to drive 100% correct all the time, 'cause the veichle will drive UNDER a table at LEGO exhibitions. -
Remotely Operated Technic Arm
nxtstep101 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I have always wanted to build a giant remote control arm but I never could since I only had the NXT set, But now since I have gotten the 8043 excavator I took a crack at it. After about 2-3 weeks of building and fine tuning I finished. I came up with the name ROTA (Remotely Operated Technic Arm) The programming took an additional day, shortly after I took some videos and put them together so here is the video explaining all the mechanisms: Pictures can be found here: http://nxtgeek.blogs...11/rota_12.html
