    Battery Buggy

    Dear Friends: As a part of my middle school science Olympiad competition I built a battery buggy using Lego pieces like axels, gears, motor, battery etc but this project requires motorized vehicle to stop automatically after going for certain distance (9 to 12 meters) and I am unable to make any progress on stopping part. Does you guys have recommendations please? Thanks, John D
  2. Hey there guys! I finally got myself an S-brick, i wanted to test it out so i built this go-kart. Functions: - 2 gears gearbox - auto clutch - braking system - differential The vehicle turned out to be pretty fast and with a great handling, unfortunately i need to wait some better weather to shoot a video of it and a bigger place as well. Like in a real kart there's no reverse gear so i'll probably need something like a parking lot to test it out. The gearbox is working great with the buttons of the S-brick operating the M motor I hope you'll like it!
  3. Here is my lastest car. The classic Volkswagen Beetle, officialy called Type 1, or informally in some places around the world the VW Bug. This car received a lot of modifcations and improvements along the years, I have built the 1967 model. This car is made in scale 1:7.8. The total size is: 65 studs of length, only 25 wide and 23 of high (50x20x18 cm) The weight is 2.5 kgs, with around 3000 parts and 5 motors. As always it includes some remote controlled functions: - Steering (M motor) - Drive (2 XL motors) - Sequential gearbox (PF Servo motor) - Brakes (M motor) The sequential gearbox is a modified version of the Mustang's gearbox (3rd Gen V2), with 4+N+R speeds and as always with auto-clutch. The speeds ratio: R - 1.25:1 1 - 1.25:1 2 - 1:1 3 - 1:1.33 4 - 1:1.67 The max speed in 4th speed is 4 kph (~2.5 mph) It has a gear indicator in the interior, between the front seats. Boxer-4 fake engine under the rear bonnet. The bodywork Also you can disassembly the bodywork removing only 5 pins, do it is very easy and fast. A complete bodywork with openable doors, front trunk bonnet and and rear engine door. Also the doors have lock, you need turn the door handle to open it. It has 4 full size seats and folding front seats. The suspension is based in the real one: front rigid beam independent suspension axle and rear swing axle. Also the front axle has stabilizer bar. The steering has ackerman geometry and working steering wheel. The car also has working brakes in all wheels: disc brakes in the fron and drum brakes in the rear. In addition it includes functional brake pedal. Now the "most wanted" picture for technic fans. Like the Mustang the instructions will be available coming soon Finally as always a little video: As always for more info visit my website:
  4. Finally !!! After two weeks of work and some months of planning here it is! my most complex creation till now. It's been such a pain adding all the features in a small space that i almost gave up a week ago....then i started from scratches and now it works really nice. It employes 2 L motors 2 M motors and a servo motor powered by a single lithium battery. I didn't expect the brakes system to be so strong but its very effective even if i think the rubber parts will get damaged soon... The auto clutch lets the car stay always in a neutral gear so it can also be used like a gravity car edit: VIDEO :D! btw, here's a list of the features: - Auto clutch system - Front wheel drive - RC Gearbox 3+R - RC Rear brakes system - Power functions - Return to center steering - Front independent suspension - Openable doors and front hood dimensions: 43cm x 18cm x 14cm 1235g weight
  5. I have been interested a lot in the flex system lately and have been reading about it a lot. It seems very useful, but unfortunately I do not have any. The one major problem that the flex system is too flexy and most of all too weak. It is merely a great idea that has not reached its full potential, but the coolest thing made with the flex system is Marvin G.'s 1:7 scale super car IMHO. The braking push-pull system is ingenious, but if it was motorized by say a pf motor, the flex system would not be able to handle the torque, but a linkage even with 1 x 6 or 1 x 9 links is much less realistic. So I am proposing metal flex cables for many uses including steering, braking, etc. They would probably be relatively easy to make (or even find at Lowe's) and would be much cheaper than the discontinued plastic ones, so the only real expense would be the connectors which are much less expensive. I wish Lego had more spur gear sizes though, I want to make a trail bike with working gear shifting and brakes like this. I think this would be a perfect use for the flex system and just wish the cables could be stronger. Sound like a good idea? Please feel free to post comments and criticism, and just hope Lego is reading this!
  6. I have the pleasure to present you my latest moc. The Caterhan Seven (also called Caterham 7) is the present version of the original Lotus Seven (or Lotus 7) designed by Colin Champan in 1957. This car is very famous because it is extremly ligth, and it has outstanding dinamic specs, which make this car perfect for its use in competition and track days. The original: This creation is made in scale 1:7. Thus remains in 29 studs wide, 56 of length and 20 fo high(23x45x16cm). The weigth is 2.2kgs. It has around 2500 parts. As all my MOCs, this includes some remote controlled functions: - Steering (PF M motor) - Drive (PF 2XL motors) - Sequential 5+R speeds gearbox (PF Servo motor) - Disc brakes (PF M motor) This car arrives with a 5+R speeds version of the all-new 3th generation of my sequential gearboxes. The new generation is even more compact and reliable. Of course it has auto.clutch It has a gear indicator in the cabin. Just behind the seats, over the rear axle are the battery and the drive motors (2XL) The Seven design is based in a tubular unibody frame with double wishbone front independent suspension and DeDion rear live axle. The front axle is double wishbone type with caster angle, camber angle and ackerman steering. The original Lotus 7 had a typical rear live axle, and the newest and powerfull version has independent suspension , but the most common rear axle is the DeDion axle. Like the real one, this creation has rear 3-links DeDion axle(you can see it in more detail in the video) The "most wanted" picture. This creationa also has working brakes in all wheels(the same brakes used in my Land-Rover) Like the real Seven, this creation mantains the unibody frame. Also to reduce the weigth, the frame and the bodywork are the same thing. The yellow liftarms in both sides of the car are the bodywork, but at the same time are the frame of the car. This picture shows how the structure is made As always a little video: For more info and pictures you can visit Fernando
