"Gearhead" AFOL xyzzzach recently posted this of a Lego Technic Mini Automatic Synchro Drive unit. "The chain spinning on the perimeter is on one end of a differential and the system that turns the syncro-drive (all four wheels at once) is on the other. When resistance is felt on the chain (running into wall), the power transfers through the differential to the sincro-drive turning mechanism. The power follows the path of the least resistance. No sensors but it call still detect and change course, all mechanically." It joins his which he says is "One of my favorite inventions. The ring gear spinning on the perimeter is on one end of a differential and the system that turns the sincro-drive (all four wheels at once) is on the other. When resistance is felt on the ring gear (running into wall), the power transfers through the diferential to the sincro drive turning mechanism. The power follows the path of the least resistance. No sensors but it call still detect and change course, all mechanically." Maybe he could add a suction device to make it one of those robotic room vacuum cleaners!

@ Moz: I like your compact design! The hyperlink above to your photos was not typed correctly (i.e., it had two http's in a row and there were colons missing). Here is the correct link.

If you ever offer your helicopter to North Americans, I'd be interested in buying one.

As pointed out on this Eurobricks Frontpage post, Railbricks Issue 10 is available for free download. On pages 12-15, there is an interesting article entitled "Are Trains Becoming Technic?" The author (Didier Enjary) states that "Train wheels are Technic parts" and "A LEGO Technic train is possible...." There is a Freight Wagon railcar that contains ~75% Technic parts; one can download the building instructions here. We've seen AT-AT Motorized Walker sets and Power Functions elements incorporated into other Lego themes. Therefore, is it any surprise that TECHNIC is growing in popularity?

Why would one want to disassemble the 8110 portal axle anyway? The two parts are like two halves of a Technic Turntable:

Yes, as Lalror said, you should be in LDD Extended Mode to see all of the available bricks -- go to Superkalle's Eurobricks post here to find out more.

Have you seen Philo's "Power Functions NXT Remote Control" webpage? Maybe the logic can be reversed:

The letters are "PB" (for the all-powerful Crowkillers, Paul Boratko)!

Nice Racers! Do you ever make car bodies that can fit on the 8183 "Track Turbo RC" Power Functions chassis? In Bricklink, it's known as the bb396c01 "Light Bluish Gray Electric, Motor RC with Steering Mechanism and Receiving Unit, Dark Bluish Gray Base":

@ davidmull: There are 19 reviews of the 8455 Backhoe on this Brickset website.

I like using MegaUpload -- it's free to use and download large files. Try it -- you'll like it!

I considered making Building Instructions, but it would be time-consuming to use the Lego Digital Designer (LDD) "Rotation Tool" on the 44224 "Technic Rotation Joint Disk with Pin Hole and 3L Liftarm Thick" and 44225 "Technic Rotation Joint Disk with Pin and 3L Liftarm Thick" parts: I don't know if LDraw has them in its Parts Pallette. I took a long time to assemble the second Optimus Prime, so I am hesitant on making photo-sequence Building Instructions....

Buzz Lightyear wants Optimus to help him with his "Zurg problem", since they've both got the same kind of Zamor Sphere launchers:

dragonite986 posted this of Optimus' young cousin which he calls a "Techniformer":

On his Brickshelf gallery, 1nxtmonster posted Building Instructions and pictures of his Lego Technic Jeep Wrangler trial truck. Weighing 1250 grams (2.75 lbs.), his "latest trial truck...used brand-new axles that were mainly inspired by Zblj's Raptor. They work very well, and the suspension is great. My best-ever vehicle." of the Jeep crawling through the leaves: Video of the Axle construction (on Lego Digital Designer): . of the bare chassis in action:

@ Teddy303: Thanks for the correction; I updated my original post. Welcome to Eurobricks, by the way!

I had fun building the 8070 Supercar set. I did it a LOT SLOWER than this, to savor every moment....

On his Brickshelf gallery, Wanucha posted 13 pictures of his Lego Technic Pneumatic Forest Crane. It is a "Modified Lego 8053.... Functions consist of one M motor, compressor, one small piston and 3 big pistons." His 110-page PDF Building Instructions are available for download on his website here. On page 2, he lists the Lego sets used: 8053 -- Used most parts. 8265 -- Used smaller parts and panel plate. 8049 -- Used smaller parts and all pneumatics. 8263, 8288 -- Used small parts and black panel. 8883 (PF M motor) and 8869 (PF switch). 8042 -- Used only pneumatics. + some other parts and a homemade 9V battery box. The shows its capabilities:

On this LUGPol post (translated into English), MIAMI recently presented his Lego Technic RC V10 Supercar2. "SUPERCAR1 RC V10 Specifications: PF XL DRIVE: Rear with PF XL ENGINE: V10 positioned centrally STEERING: PF MEDIUM GEARBOX: 4 speeds (backward and forward) SUSPENSION: Independent (about 2 studs behind, in front of Max 1 stud ground clearance) DIMENSIONS: Length 59 studs / 25 studs width / height 16 studs WEIGHT: 1.7 KG FEATURES: Remotely adjustable rear spoiler / remotely opening door with a mask, 2 x 2 light activated by a switch, manually open sunroof and hatch, remotely controlled ADDITIONAL INFORMATION: 1) The steering wheel rotates in the direction of the wheels when cornering 2) Pistons in the engine works well, when we have run in the "N" that is at ease DESCRIPTION: The car is almost entirely my own design, the only part of a borrowed 4-speed gearbox from the sariel.pl [website] and a pair of patents from an 8070 set. In this model have been used 2 engines and 1 MEDIUM XL engine, two receivers and two transmitters. Action 2 engines is described above and the last third MEDIUM engine is responsible for opening the door with a mask or control of the rear spoiler. At the moment we can only control one of the above functions, and set the yellow switch to the left under the flap and the right switch is used only for the lights."

You may have to add some "idler wheels" (in between the three main drive sprockets) to take the slack out of your Technic Treads, so they don't fall off on tight turns.

Some fellow made a full-size Optimus Prime truck out of his 1994 Peterbilt! There's a nice article about it in the New York Times.

Welcome to Eurobricks! You're on the right track (pun intended)! Making a compact Track Loader (like the Komatsu pictured below) will be fun. You can buy an extra Lego Power Functions (PF) XL motor from this Italian Shop.Lego.com webpage. Scroll to the bottom of that webpage to see other available PF elements. You could also shop at one of 111 Italian Bricklink stores if you prefer. Search for the Bricklink part number "8882" or "58121c01" to see who sells the PF XL motors. You can change the currency to Euros at the right-center of the webpage you see. A lot of your questions are answered on the Powerfunctions.Lego.com FAQ (Frequently Asked Questions) webpage. Be sure to navigate all around that website to find out more. The 8878 LiPo "Power Functions Rechargeable Battery Box" is economical if you're going to play with your MOCs a lot, and it is LIGHTWEIGHT and COMPACT.

Yes, Nathan Gibson did a great job designing his Technic Prime. He likes Transformers -- here is his picture gallery showing Optimus' evolution over 3 years' time:

Over on this TechnicBRICKS post, Conchas has added a few images of the new 24-Tooth 28-Tooth Lego Technic mini turntable that will come with the 9397 Log Transporter set. He wrote, "Like speculated, it has an outer diameter of 24 teeth 28 teeth. I made a quick and dirty LDraw doodle to show what it probably looks like: [28 teeth not shown here -- 24 teeth are] "Of course, we all hope the middle has a pin hole instead of an axle hole. Lots of future possibilities with this new fella!"

I used Yahoo! Babelfish to translate the Korean BrickInside webpage to this ROUGH English translation. I saw the new 10220 VW T1 Camper set at Brickcon 2011 two weeks ago, and I like how you were able to fit the Lego Power Functions (PF) elements inside. The battery box is stuck on the removable roof, and the PF Receiver is peeking out from the roofline. I like the "Sunsky Steering" too!
