This is my first MOC on this site! Bear in mind that I have only been building for slightly more than 2 years and don't have a very large collection, so my builds aren't exactly Sheepo standard... The car is a 1:10 model, although I had to deviate from the scale slightly in order to fit the functionality I wanted into the car (width was increased to 25 studs for example). Here are the features (LONG list): Remote control drive with three EV3 Large motors. Top speed around 5mph. Drive goes to all four wheels via two diffs. Remote-control steering with EV3 Medium motor. Turning radius is rather large though. 8-speed automatic hybrid gearbox. Basically a 4-speed automatic and a 2-speed ratchet gearbox (inspired by Sariel) used together. A model piston engine (V6) in the front with engine capacity scaled to the real car (I measured mine at 3.77cc, real car is 3.8l). Lever in cabin with Drive/Neutral/Brake settings. Handbrake system and rear friction brakes. Full independent suspension with negative camber angle. Adjustable ride height for each wheel through tuning dials (front ones are under the hood, rear ones are hidden next to the spoiler). Adjustable castor angle for each of the front wheels (adjusted by rotating the turntables). Opening sprung doors with locks. Opening sprung front hood. Cabin with fake steering wheel (non-rotating), FOUR SEATS and a floor. Pic with doors and hood open, revealing the model engine. The red pads on the hood are rubber friction pads (from EV3 Education Expansion set) - these keep the hood closed. Close ups showing the piston engine and suspension. When the tuning screws are turned, a worm gear system rotates the arm where the shock absorbers are mounted. Adjustment range is about 2 studs. Castor is adjusted by turning the turntables - this effectively rotates the entire suspension system relative to the chassis. Beams from the chassis are placed to interfere with the rotation of the turntables - this keeps the turntables in place when not adjusted. The cabin is fitted with a full set of 4 seats, as in the real car. The occupants of the rear seat are given the rare treat of having gears from the 2-speed ratchet gearbox right next to them. When the drive setting is enabled, a driving ring allows the motors to drive the 4-speed gearbox. In neutral, the driving ring meshes with nothing, letting the car roll freely. In Handbrake, the driving ring locks the input shaft of the 4-speed gearbox to the output using a gear ratio that isn't part of the gearbox, effectively locking the shaft. This is like solving the equation 3x=x (x is the rotation speed of the shaft) - x can only be zero. Part of the drivetrain is shown here. The differential and elastic system measures the resistance on the input. The system on the bottom-left shifts gears when the resistance is too low or high. The 4-speed gearbox is a standard 5/3/1.67/1 design - the 2-speed's gear ratios fit "in between" these. Notice the towball links and lever below (remember this is an upside-down view) the gearbox. Those control the rear brakes. In Handbrake mode, the brakes are engaged. Here is a graph showing the 8 power bands (created with Microsoft Excel). The lines are cut off when the spreadsheet calculates that the motors run out of torque. This graph used data from my test runs, so the performance shown here is similar to that in real life. Top view of the rear with the body removed. The drive motors are visible, and the 16-tooth gears (used as tuning dials for the rear suspension) can be seen. This is the underside of the rear axle. When the towball link is pulled, the red rubber pad swings outwards and grips the inside of the wheel. I made the rather radical decision to leave the EV3 brick exposed at the back. I decided that covering it up would require too many parts, add too much weight and deviate from the scale. The GTR's four red rear lights are modelled with new-type 16-tooth clutch gears. Overall, I think this has been a successful build for me, cramming in far more features than any of my prior builds (in fact, I am yet to see a 1:10 supercar model with more functionality). However, some things could have been improved: It isn't a perfect scale mode. The seats are way too far forward - I had to do this to fit the monstrous powertrain inside. The rear end aesthetic requires, well, some getting used to. Rear wheels sometimes rub against the top of their fenders. Can be solved by setting the tuning to maximum ride-height. Negative camber angle is too pronounced. Steering lock is very small, and gets even smaller if castor angle is set to extremes. Gearbox tends to be rather "reluctant" to shift gear - this was the only way to stop it from constantly alternating between two gears. It isn't exactly GTR like when driven. GTRs are known for their acceleration, but the model takes ages to get up to speed. It drives more like a truck. My next build will be my Porsche competition entry - no EV3 will be involved for that, although plenty more features (did someone mention 4-wheel steering?)... -
Do you have long hair getting in the way when you build with or sort LEGO? If yes, now you can hold your hair back with a wearable LEGO headband MOC. There's cat ears with Hello Kitty. It can also be used for cosplay.* Cat Ear Headband by dr_spock_888, on Flickr If Hello Kitty is too cute, try the Jar Jar Bink headband.

Just a bit of an introduction before I start. I'm pretty used to building small-scaled MOCs, nothing using the TECHNIC building system. I've got a couple of the sets, but that's pretty much it. This is my first TECHNIC MOC. MERCURY features a 4-speed transmission based on one of Sariel's designs, independent front and rear suspension, HOG steering with linked steering wheel, and shock-absorber assisted doors and rear engine cover. The spoiler is operated by a small switch on either side of the car, and can be moved up and down. The car itself is mid-engined with a working V8. Please give me some feedback if you can, I'm trying to expand my horizons with TECHNIC, as it's very different from what I'm used to. -
Hello everyone, I present you another motorized and remotely controlled hot rod – Black coupe. My goal was to make mid-sized model with realistic suspension and working engine. Regarding size and functions it is somewhere in between my models “Fire bucket” and “Lucky 13”. Dimensions: 41 studs long, 19 studs wide, 13 – 14.5 studs high and weighs 804 g. PF components: 1 L motor - driving, 1 M motor - steering, 1 8878 battery, 1 IR receiver As you all know, with motorized creations, it is always a problem to place PF parts so they don't influence overall appearance of a model. In my previous hot rods, I used place under the false engine to put PF motors and as a result, false engine had to be higher than in a real car. That was a little bit frustrating but I didn't see any other option. So with this hot rod, I wanted to avoid that at any cost. Some compromise had to be made so I decided to use just one L motor for driving (accepting the fact that it won’t be very fast) and to put it under the driver’s seat. M motor for steering is placed next to it, under the passenger’s seat. As a result, smaller custom made V8 engine is placed lower on the chassis - right where it would be in a real model. Other functions: Working suspension - I wasn’t 100% satisfied with the suspension of my previous hot rods (they worked but weren’t realistic enough) so I really wanted to make improvement in that area. Development of the front solid axle and rear live axle, leaf spring suspension (with all the links and dumpers) was, at least for me, most important and most challenging part of this model (considering the scale). Front: solid axle, leaf spring Rear: Height-adjustable, live axle, leaf spring Working steering wheel – drag link steering Development of the small custom V8 with moving parts (working pistons, radiator fan and a generator) was the most satisfying part of this build Working door handles – openable suicide doors Trunk door can be opened – behind it is a mechanism for adjustment of rear height of the vehicle (manually controlled gear) and battery (easy to turn on/off and charging). Roof can be removed easily Retractable rear license plate – controlled with a fake handbrake lever inside the cabin I just love this function, I had it already on my Lucky 13, but for this build, I wanted it to be controlled from the cabin (driver's seat) for more realistic appearance. Features: Custom chrome parts – wheels, headlights, radiator grill, door handles and rear view mirrors Interior – red seats and dashboard I hope you'll like it, please comment and tell me what you think More photos: http://www.flickr.co...157666582891052 -

Hi guys! I am new here so I wanted to show you my trial truck! http://nxt45.files.wordpress.com/2013/11/img_0705.jpg Full description & YouTube video on my blog: http://nxt45.wordpre...go-trial-truck/ (how do you post YouTube videos?) As always Happy building! NXT45 -
Guys & Gals, Here's a Theo Jansen inspired strandbeest (walker) with 24 legs. It's crankshaft has six points (not 4) like most builders use. It walks pretty well. I'm working on the building instructions which is taking quite a while. I have some learning to do on LDD and LDraw and etc. But here is a still photo and a youtube video.
