Hey, guys: It's been a while since my last post. Please let me present my latest moc: Top Fuel Hydroplane. During this build, I tried to keep the original look of it and also included the "Wheel Drive Mechanism". My Detailed Version Features: V8; Electric, Fuel and Forced Induction Systems; 2 Counter Rotating Propellers, transmission and clutch, adjustable flaps and 2 drag chute bags (The two engine blocks at the very end) . The main idea is really put this boat on top of a Top Fuel Dragster..) Video:

Good Day ! While I am still waiting for my extension wires and test pipes(for my RC motor powered centrifuge), I decided to build a trophy truck. I know there are a lot of racing version out there and I thought I could come up with something new. a cop version. It shares almost the same chassis with my previous desert patrol buggy(http://www.eurobrick...=139391&hl=) and it's powered by 2 L motors as well. In addition, there's a blower(twin screw type) attached to the V6. Update: It's raining again I guess I have to wait for another couple of days to make a video...sorry.

Thanks guys ! and by the way, the shoes belong to my girlfriend, I will pass your commendations to her .

thanks ! video is up now

Thank you for the coolest comment! Thanks, which tire are you referring to? the front or the rear ones? I don't have any of them . I will post a video after it stops raining... Thanks ! Thanks for pointing that out. The truck doesn't have any lift arm mounted crosswise.The weakest part of this truck is the rear section of bed rack. Good to know something new to learn !Thank you! The battery is mounted 3 studs above the motors and it is sitting on top of a bent lift arm . Even if I lower it 1or 2 studs, I still have to rebuild the door panels and the trunk. Anyway, I will pay attention in my future projects :sweet:

Thanks a lot for your suggestion. I would definitely try to drop couple of studs tomorrow and possibly post a video Thanks ! Your video inspired me to switch the colour of the door panel to white

Thanks, specially after putting the batteries in, the rear is slightly lower than the front Thank you, I only tested on my carpet floor, it drives fine. we had a heavy rain yesterday and it is still wet outside. I will make an outdoor test drive tomorrow or so. Thank you ! The rear splash shield should look better with soft axils, but I only got 2.. That's a really good point ! Luckily due to the design of suspension, It barely rolls left or right. Also I have a relatively wide frame, these should neutralize the high COG problem (honestly I didn't put COG into consideration until you mentioned it )

Hey, guys ! I have another non-vehicle moc for you, a morse code straight key and receiver. The straight key is actually a lever with one end connected to the controller. The receiver consists of one battery box, one IR receiver and one pair of LEDs. This is really a remote controlled lights. Here is the video. (The beeping sound is added later after recording, the receiver doesn't make any noise.)

Thank You ! Yes, the answer is "apple". You can still bring this to the exam if cell phones are prohibited. That's a great idea. I actually built a typing machine which is simply a one sided return to centre steering mechanism with a pencil tied to the end. I found out that It was very hard to get the timing right so I had to leave a "giant" space between each letter. If I place the pencil closer to the paper, it prints short and long lines, no dot at all... That's why I decided to use indicator light and dropped everything else. Someone suggested that I could use NXT to record the code, but I don't have one... Wow ! that is super cool ! what are the two straight key looking things covered in grey boxes? Since I did try to build a printing device but it didn't work out very well, I would say it is a accidental simplicity.

Thanks, I think I will use only 1 RC motor.. Here is the video with 2L motors.

Hi, guys ! Here's my latest moc(very close to finish), a dune buggy. 2L motors for driving and 1 servo motor for steering. Help: I am thinking about switching to 2 RC buggy motors, do I really need 2 battery boxes and 2 IR receivers? What if I choose to use 1 battery and 1 IR receiver? How big is the power loss and will it damage the receiver? Thank you for your time !

Thank you ! and the bottom of the two shock absorbers are connected all the way through

Hi, guys ! There're a lot of aircraft carrier mocs out there, so I thought I could introduce my catapult system. The main catapult mechanism is simply a winch plus a clutch. (powered by one L motor) I used another L motor & 2 actuators to control the JBD. The acceleration is quite fast considering I am using only one rubber band. You may also attach more rubber bands if you have heavier fighter Jet mocs or RC planes. Here is the video as always ! [/media] [/media]

Thank you for all the comments and insights ! Here is my plan: 1. Build a close in weapon system since it will be the smallest functioning unit on the carrier. (currently working on it and will provide video demo as well as LDD) 2. From there, I can decide the proper scale of the ship 3. Build other functioning modules, lifts, control tower...etc (will provide videos and LDDs) 4. Finish the ship in LDD. Sorry to say but I am not going to actually build the entire ship.

Hi , here is my latest moc: a lego centrifuge. The application of such a device is to separate plasma, white blood and red blood cells. Mixtures inside the test pipes will experience great horizontal centripetal force（multiple of g）and thus reduces the time required for precipitation. Powered by 4 Large motors. 1st gearing up is: 36:12, 2nd gearing up is 20:12. Total gear ratio is 5:1 *This is probably one of my ugliest creations ever. This is the result : Here is the video:

Thank you for all the comments. My RC Buggy motors arrived today.. So.. Upgrades will be available

Thank you ! That's a really good idea. You saw how I slowly turned it on and off . I am in ! Thank you for letting me know.

Very nice build ! I think you forgot an onboard speed radar and some donuts on the passenger seat....

Than kyou ! oracid. His L motor was set at 272 RPM @9V without loading or gearing. I don't understand why...Philo has some great data as well and it says 390 RPM.. It's between 1360 and 1950RPM. Pretty Sure !

Thanks for commenting ! Short answer is I don't know the actual RPM. Without load the rotor alone has around 1900RPM ideally. since lego official says that L motor is 380 RPM and I have a 5:1 gear ratio. I wish I had a proper device to measure the RPM, then I can calculate the gforce. For seperating the ash from water, It will take 2min 20 seconds to get a similar result. (I just tested lol). For the "walking" issue, I was able to solve it by placing damper system beneath it. After 16 trials, Finally !

Hey guys ! Let me introduce my new MOC: the mousetrap ! Features: realistic mechanism (2 leverage systems), powered by 4 rubber bands. I tried to make it look like "Victor's" but had difficulty to recreate the spring in the middle. So I attached 2 rubber bands on each side of the hammer. By doing this, the travel of the hammer will actually stretch the rubber bands far enough so that they will produce enough potential energy. Here is the picture: And here is the video including setup process and more detailed explanation. Here are some more detailed images.

It's a kind snack from Korea. For trapping a mouse, I would recommend the actual Victors. That is a more affordable option to go

It won't happen since I've already part it out Thank You !

It is able to crack an egg, so it does hurt a little but not as powerful as the actual "Victor". If you want some serious damage, more rubber bands will do the job I would bury it in the bucket of legos. lol

Hey, guys ! Here's my second moc: a kart with some off road ability. Features: power functions, independent suspensions, RWD(powered by 2 L motors) and some details. Didn't create one with similar look but this image is where my idea came from. :D The challenge was fitting everything in the back, fuel tank, engine, ir receiver and battery. The scale was bigger than what I originally planned. The video is here. : ) Thanks for commenting !
