Tamas Juhasz Posted May 30, 2012 Posted May 30, 2012 (edited) Hello! I decided to share my mocs here with this professional team. I build technic vehicles, LPEs, etc. since long ago. I'm member of Malug(hungarian Lego users group), Hunlttc(non official hungarian Lego truck trial team). I build mostly trial trucks(lot of them waiting for upload), contsruction vehicles, models. Brickshelf: http://www.brickshelf.com/cgi-bin/gallery.cgi?m=mbmc137 Youtube: http://www.youtube.com/user/1hengeresVmotor?feature=watch A few older moc: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=442373 http://www.brickshelf.com/cgi-bin/gallery.cgi?f=493335 http://www.brickshelf.com/cgi-bin/gallery.cgi?f=459855 http://www.brickshelf.com/cgi-bin/gallery.cgi?f=485582 Nowadays I realize some of my ideas: 1. Flying machine: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=500935 A simple flying object which isn't a single propeller, so can be a machine. Max. height is about 0,4-0,5 m, but it rises from it's own power(pullback motors). 2. Radio controlled gearbox with RC unit: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=502229 Uses simply the servo output of the RC unit, so you don't need another motor for shifting and both 9V output is free. Recommended for bigger and heavier vehicles because it needs some space. Ideal for vehicles with RC system. The truck is a study of suspension, the rear one is my own development for heavy trucks: The axle is suspended in four point, strong rubber bands are the "springs". With rollers in the wheels they can carrie much load. In the front axle only the gray 10x1 technik plates(instead of 9L links) are new: http://www.brickshelf.com/cgi-bin/gallery.cgi?i=5465283 The axle contains the old differential with lock too. 3. Another gearbox, but for small vehicles and relatively low torque: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=504221 In this case: http://www.brickshelf.com/gallery/mbmc137/Ideas-Technologies/4speedRCgearbox/004.jpg - it would be a simple(but not usable) motorized gearbox. With 3 more pieces it doesn't allow to be two speed engaged at the same time: http://www.brickshelf.com/gallery/mbmc137/Ideas-Technologies/4speedRCgearbox/005.jpg The motors help each other. In the sifting from 1. to 2. speed wit the (1.) motor, the another motor(2.) is in central position, nothing extraordinary happenes. But in the shifting from 2. to 3. speed, the steering piece pulls off the driving ring from second speed and the (2.) motor engages the 3. gear. The gearbox needs friction in the axle of the red shifting piece to prevent the "re-central positioning" of the motor, which turns only a 1/4: http://www.brickshelf.com/cgi-bin/gallery.cgi?i=5480676 Shifting from 1. to 3. and 2. to 4. speed don't work, but you can shift from 1 to 4 or backwards. The most important: in this gearbox each position of the contollers levers corresponds to one gear: Right lever down: 1. Right lever up: 2. Left lever down: 3. Left lever up: 4.

Alasdair Ryan Posted May 30, 2012 Posted May 30, 2012 Welcome to Eurobrick's,I like your rc excavator. Quote
Saberwing40k Posted May 30, 2012 Posted May 30, 2012 I bid you welcome. If you would, please deeplink images in the future. If you don't know how to do this, there is a tutorial somewhere on the site. just follow This link , and read up. there are also tutorials for resizing big images, which you might want to read. Oh, and with your permission, can i help you post about some of your old creations? Pretty please? Quote
Tamas Juhasz Posted May 30, 2012 Author Posted May 30, 2012 (edited) Thanks for welcome! The excavator was built 2 years ago, model of a CAT 385 CL, fully remote. The 3 ideas are my latest creations. (and a lot of relatively new mocs are waiting for upload, in the gallery are mostly older ones, but I don't have much time recently) If you would, please deeplink images in the future. If you don't know how to do this, there is a tutorial somewhere on the site. just follow This link , and read up. there are also tutorials for resizing big images, which you might want to read. I know deeplinks(in the Malug forum we post mostly with normal links), but thanks for the information, I will post in the future with deeplinks. Oh, and with your permission, can i help you post about some of your old creations? Pretty please? Thanks. If I know well, after 10 posts I can write to members in private. I think my TT-s and miniTTs should have an another topic, if you can it would be great a post about them. First about the Zil-136. Edited May 30, 2012 by Mbmc Quote

timslegos Posted May 30, 2012 Posted May 30, 2012 Looks like some great MOC's. That truck with the PP wheels is huge! tim Quote
Big Cam Posted May 31, 2012 Posted May 31, 2012 Welcome to the forum Mbmc, please resize your images when.you get a chance. The site maximum is 800x600. Thanks, sweet MOC by the way. Quote
Tamas Juhasz Posted May 31, 2012 Author Posted May 31, 2012 Welcome to the forum Mbmc, please resize your images when.you get a chance. The site maximum is 800x600. Thanks, sweet MOC by the way. Thanks. Resize: if 800x600 is the maximum, then some details will be hard to see in my mocs. For example: http://www.brickshelf.com/gallery/mbmc137/Caterpillar-385-CL/Building/img_212_1024x768.jpg Is there auto resize, which resizes the picture like above, but to 800x600? I can't upload them in 800x600, that's too small. Quote
bb15080 Posted May 31, 2012 Posted May 31, 2012 (edited) you can use easy thumbnails to make the photo's smaller nice moc's I really like your Model of the Caterpillar 797B Edited May 31, 2012 by bb15080 Quote
Tamas Juhasz Posted June 1, 2012 Author Posted June 1, 2012 Thanks all! Sorry for the big pics, now I have smalls for my latest idea, so I can write a better interpretation of this 4 speed PF remote controlled gearbox: Folder: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=504221 I built it for small vehicles and relatively low torque, I think this is the samllest remote 4 speed gearbox. The main aim was to be compact/small, simple, and easy to control. You don't need special parts or the big NXT unit to switch between gears. The motors help each other. In the sifting from 1. to 2. speed wit the (1.) motor, the another motor(2.) is in central position, nothing extraordinary happenes. But in the shifting from 2. to 3. speed, the steering piece pulls off the driving ring from second speed and the (2.) motor engages the 3. gear. The gearbox needs friction in the axle of the red shifting piece to prevent the "re-central positioning" of the motor, which turns only a 1/4. The motors are stalled for a half second, but it's minimal. In this case: - it would be a simple(but not usable) motorized gearbox. With 3 more pieces it doesn't allow to be two speed engaged at the same time: Shifting from 1. to 3. and 2. to 4. speed don't work, but you can shift from 1 to 4 or backwards. The most important: in this gearbox each position of the contollers levers corresponds to one gear: Right lever down: 1. Right lever up: 2. Left lever down: 3. Left lever up: 4. Can be seen working in this video: What dou you think? Quote
DLuders Posted June 1, 2012 Posted June 1, 2012 I like it! Are you going to place that Lego Power Functions Remote-Controlled Gearbox in a large MOC? Note that your Brickshelf folder is not yet "public", so we cannot see your Building Instructions yet. Quote
Tamas Juhasz Posted June 1, 2012 Author Posted June 1, 2012 (edited) Thank you. I know the BI isn't public yet, but soon it will be. I think it's easy to build even from these pictures. Are you going to place that Lego Power Functions Remote-Controlled Gearbox in a large MOC? - Yes, it's already placed in my new project(4x4 off-roader model). But that's not so large, has 81,6 mm wheels. Edited June 1, 2012 by Mbmc Quote
Tamas Juhasz Posted June 2, 2012 Author Posted June 2, 2012 The instruction is available now: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=504222 Does anyone planning to try it out? I used it in a medium vehicle directly after one Rc buggy motor(powered from PF BB), and worked well with that torque. Quote
Tamas Juhasz Posted June 8, 2012 Author Posted June 8, 2012 Nowadays I found some yet haven't used(or I haven't seen) pieces and combinations. 1.: Combination between turntables, so you can easily connect studless and studfull techniques: 2.: A reinvented piece from the RC system's steering unit: I took out this piece from the "Black Electric RC Race Buggy Steering Unit" - BL number 6282. This can be used as a 4x3 T liftarm. You can take this out without damage, only screws are there: 3.: A spline shaft from the pull-back motor "motor0" : This needs maximum 1 stud place: http://www.brickshelf.com/gallery/mbmc137/Ideas-Technologies/Spline-Shaft/012.jpg So there isn't friction there when you place it in a small moc, 1 stud width is enough for it. The maximum extension with reliable working is 1 stud as can be seen from the pictures. I think it's enough in the most cases. What do you think? Quote
Saberwing40k Posted June 8, 2012 Posted June 8, 2012 Excellent, especially since it uses only non modified parts, which should make the purists happy. And really, what else would you use a pullback motor for? Quote
AndroTech Posted June 8, 2012 Posted June 8, 2012 Outstanding!!! I love it! Love the idea with the universal joints. This will come useful when you want to transfer power to attachment on a tractor, which has three point attach system. Quote
timslegos Posted June 8, 2012 Posted June 8, 2012 The spline joint idea is awesome! Would it count as being a pure Lego solution? tim Quote
Tamas Juhasz Posted June 9, 2012 Author Posted June 9, 2012 Thank you all. The spline joint idea is awesome! Would it count as being a pure Lego solution? I think it's a pure solution' date=' because if you are enough skilled, you can take the white piece out from the motor without damage. it uses only non modified parts, which should make the purists happy. And really, what else would you use a pullback motor for? I found one more way to use them: for accelerate a flying machine's propellers: http://www.brickshelf.com/cgi-bin/gallery.cgi?i=5432841 So this pull-back motors are surprisingly useful. Quote
Tamas Juhasz Posted July 16, 2012 Author Posted July 16, 2012 (edited) Hi again! Nowadays I wanted to build something extraordinary Lego gun. Generally I have developed further TheTechnicKiwi's firing mechanism: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=487705 - I thought it would be good with possibility of moving and a larger clip. So I made this: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=507850 Two RC buggy motors are responsible for shooting, they allows max. 660 shot/minute, if the battery is full. This is a bit faster than the Thompson submachine gun. This turret has an undercarriage for moving in all direction, and for moving the upper structure with the gun. min - max tilt: http://www.brickshelf.com/cgi-bin/gallery.cgi?i=5536550 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=5536552 Only the gravity is responsible for reloading, the ammo simply falls down. The ammo clip can store max. 60 3LstopAxle, the gun can shoot them all in 5,6 - 6 second. Maximum range is about 2m. The undercarriage is as simple as it can be, it's only for moving with it's 3 wheels and two XL motors on each side: http://www.brickshelf.com/cgi-bin/gallery.cgi?i=5536569 The video shows it in action: - sorry in advance if you are a castle minifig fan (I didn't placed all the pictures directly here, in the BS folder everybody can see them) Edited July 16, 2012 by Mbmc Quote
Zerobricks Posted July 16, 2012 Posted July 16, 2012 There's a differrence between 660 shots/second or minute Quote
Tamas Juhasz Posted July 16, 2012 Author Posted July 16, 2012 (edited) Yes, I misspelled. Thanks. But it would be good. Edited July 16, 2012 by Mbmc Quote
Tamas Juhasz Posted July 28, 2012 Author Posted July 28, 2012 I made the video for my old parking car: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=409494 Functions: driving, steering, working steering wheel, differential lock, 4speed gearbox, parking mechanism. The functions are operated by wires and a pneumatic switch. Quote
DLuders Posted July 28, 2012 Posted July 28, 2012 I like the 5th wheel parking mechanism for getting into tight spaces! Features: "driving, steering, working steering wheel, parking, independent front suspension, differential lock, 4 speed gearbox." Quote
