896gerard Lego creations
896gerard posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello, I am 896gerard, a passionate Technic builder. I would like to extend my activities to Eurobricks. Youtube channel: https://www.youtube....X_uErOTcGpZg8Ug MocPage: http://mocpages.com/home.php/52513. One of my new creations is the Ultra low cargo bed truck. I have not found this model in reality, so I built it. The complete review is on http://mocpages.com/moc.php/396635 and the video is below. Another creation is The Easiest Parking Car In The World: this is my own genuine idea, maybe some others have had the same idea right now... The review can be found on the given Mocpages address. You may always reply if you don't like it, my MOCs will probably get better of it. -
Vote Poll: Which do you prefer type of battery for power function LEGO
Deafpilotboy posted a topic in General LEGO Discussion
For Power Function Train, which do you prefer type of battery power function? Both have it own pro and con.... Power Functions Rechargeable Battery Box 8878 Or Power Functions AAA Battery Box 88000 VOTE HERE POLL! http://www.poll-maker.com/poll116886x56B946D1-4 Not know the different in both battery? read on more below. Power Functions Rechargeable Battery Box 8878 It rechaged by plug into the wall input. very convince way to recharge it up. But the question is how long dose the battery cycle life span last in long term? If it ran out of cycle charging out, you have to buy the new one for retail value USD $49.99. Very easy to leave the battery in the lego train and just put wire in the train while charge without need take them part to replace it. Power Functions AAA Battery Box 88000 The most cheaper battery pack retail value USD $12.99 that require you to put in 6 AAA battery, value of it may be reasonable if you use rechargeable AAA battery instead of disposable battery. For long term, you can have that one pack for life time and easy replace the old aaa battery for cheaper. But depend on the train lego, some will require you more time to take lego apart to pull out the battery AAA battery, recharge it, put back in LEGO train to play with it.

If you are old enough you may have owned this toy. I loved this as I was a little child but my mother did not buy me this (LEGO neither, of course). Since then, this toy ran out of my memory until last Saturday I discovered it in a toy museum. Now I have the money to buy this toy but nowhere I can buy... The only alternative, perhaps, is to build this. As expected, it brings lots of joy to my kids. Video:

Hello all, I am thinking about making a Santa Fe or similar EMD-F7 train. As I may create the full train (ABBA - 10-12 Coaches) I need to know how many train motors I will need to pull this lot. The train should be close to the 10020 with the B unit being James Mathis design. As this is a WIP I have not yet fully designed the train. I will be using Power Functions train motors as 9v is getting expensive. Also rechargeable battery boxes and lights. So how many motors will I need for pulling all of this? Thanks, - darthluke

Measuring Power Loss in Gear Trains
Hrafn posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Has anyone attempted to measure the power loss from gearing motors up or down? What I'd really like to find is something like Philo's excellent work on motor specifications, batteries, tire traction, and so forth. Ideally it would compare all common pairs of gears (8/8, 16/16, 12/20, 8/24, 8/40, etc.) for at least a couple of motors. -
It's been a while since I've been "in the loop" unfortunately living in Canada has its disadvantages, one being that you cannot find a single soul to talk about lego 12V trains with. I've built some decent sized layouts. Right now, I have a pair of layouts that appear to be connected but aren't. They share the 7866 level cross-over track, but never actually connect via track. I've got a couple of questions. Right now, I have 3 motors, and 3 trains, and two Transformers (I also have an Austrailian one if anyone wants to buy it, I have no idea where to get a converter for it!!?!?). I have somewhere in the neighbourhood of 9 switches, unfortunately only two or three that have power to them. I'm wondering: 1.) Can I use multiple transformer on shared track - I'm assuming no? 2.) Specific instructions to boost power to the tracks, I once had a huge layout and so many issues with trains slowing down because of the shear length of the thing. What's safe, obviously these motors are getting harder and harder to come by, so I don't want to damage one. I use 110 -> 220 inverters for both Transformers. In Summary: "Mono" means one, and "rail" means rail: This concludes your monorail training. Thanks all!

Power Functions Motor Coasting
Jim posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
After building the 9398 4x4 Crawler I have been wondering about the difference in behavior between the Power Functions XL-Motor and the older Power Functions L-Motor. My concern is about Motor Coasting. Coasting is defined as "Performing a natural deceleration of a motor when the power is removed". In layman's terms; the vehicle continues rolling a bit, until completely stopped, so no abrupt stop. When the power on the XL-motor is removed, the motor coasts gently to a halt. However, when the power from the L-motor is removed, it abrubtly halts without coasting. This results in very shocky behavior, which I think can be done without. Any idea why the two motors behave differently? And more importantly; is there a way to use the new L-motor with coasting behavior? Possibly with a 24T Clutch Gear or other mechanism/technique. -
This is appalling to my minifigs... ^^" The carriage falls at top speed due completely to gravity. Basically speaking, bricks will be loosed a little bit after 3-4 falls but the machine can still function properly. No bricks will be detached or torn apart, except that a little hand of one of the minifigs fall out after perhaps 40 falls (ref: the following picture) ^^" The following pictures show how it functions: Want to see it in motion?

Another facility of my Friends' theme park. I wish not only girls love it, but also boys do. As a father of a 5-year girl, I have won her heart and let her go nut. You may do the same to your daughters/lover/fiance/wife. The girls like to bump the others. Sometimes it can be a head-to-head bump. The bumper cars are driven by magnets underneath. Enjoy. This bumper cars set is consisted of 3 major components: (1) The baseplate, which resembles 10196 (but not a full copy) (2) The turntable, which looks a little bit complex (3) The top plate Please have a look at the following video: The cars are powered by magnets. If you want to know further how it operates, check this video of "the making of bumper cars" https://www.facebook...&type=2 This is a CUUSOO project. Please support if you really want it to become an official LEGO product: http://lego.cuusoo.c...deas/view/53204 My former works of the Friends' Theme Park for your easy reference: 1. Grand Carousel: http://www.eurobrick...showtopic=87068 2. Ferris Wheel: http://www.eurobrick...showtopic=87882 3. Gyro Drop: http://www.eurobrick...showtopic=88256 I am currently working on part V of this theme park and so far I have no idea of where should I stop. Perhaps this theme park is ever expanding. I may be a bit clumsy. Still sincerely hope you enjoy my work.

This is Part 3 of my project. After rebuilding the LEGO official products of 10196 and 4597, I start to build a true MOC. It is a CUUSOO project and it awaits your support: http://lego.cuusoo.c...deas/view/48013 The girls of LEGO Friends need more excitement and here they go to the Gyro Drop (or Falling Machine). It is a 10-seater gyro drop powered by a motor and remote control (optional). Yet it does not merely operate with electricity – it operates with the magic of magnet!!! Safety to the girls is always the utmost concern!!! The carriage may fall at an alarming speed but the girls won’t feel any shock when they come to the lowest point. The carriage cannot reach the floor – the magnets underneath helps to float the carriage!!! At the same time (when they come to the lowest point), the girls won’t feel any vibration as the magnets sideway help to stable the carriage. The girls' feet are exposed to feel the breeze when they feel the excitement. The carriage only has minimal contact with the stand, so that it can fall very smoothly. Movie clip of this Gyro Drop -- Former works: (I) Friends' Grand Carousel 10196: http://www.eurobrick...showtopic=87068 (II) Friends' Ferris Wheel 4957: http://www.eurobrick...showtopic=87882

Flash Element for Power Functions Lights
runekokholm posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
For some time I've been missing flashing PF lights. Yes, you can achieve flashing PF lights with motors, but there has to be a better way, also to allow more dynamic flashing options. A suggestion for this is shown below. It's also on Cuusoo - support and share if you like it. Flash element allows you to create flashing PF lights by setting the duration of the light/flash and delay (time between light/flash) plus an A and B version for more exciting flash combinations for your creations. Flash element must always be on top of connections to other elements to avoid interfering with their power supply (flash will only affect elements added to the top of the flash element). If you need more flash elements on the same battery box: simply add an extension wire and then the flash element. The unit will always flash, no matter the direction of the current. Old 9V bulbs would change state from flashing to fixed if current was reversed. PF flash element will always flash. -
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 -
Here's a creation that satisfies BOTH the fans of Lego Pneumatics AND Power Functions! fr3dpivo posted a of his "Lego Technic 9398 4x4 Crawler mod with height adjustable suspension, stabilizer bar, compressor and modified body. Hope you get ideas for your mod :-). Compressor design by DOTTECHNIC" [second below].
