Thanks for the review, for now I'm sticking with only the excavator for this season...

If you're interested in LEGO clock designs, there's a whole world out there... have a look at this website: http://www.zefdamen.nl/Lego/Lego_clock_en.htm or this one: http://popbubble.com/Lego/LegoClocks/ As for the drawings you show, Leo's LEGO Designs is one of those pages I keep coming back to - full of ideas and interesting techniques.

I much prefer the guillotine: at least that is only a representation and "no LEGO was harmed in the process". Don't even want to see those videos, if only because the creator of the video might get the mistaken idea people like his video based on the view count.

I've found it on several e-shops in the Netherlands, available August 10, lowest price: €129,95

You just had to rub it in, right? (I do agree though :) )

Interesting steering configuration. The angle of the wheels doesn't appear to help a lot when trying to go straight over obstacles, or is that the slack in the steering mechanism?

I agree it is good - it's just incovenient for this kind of constrctions which is why I wwent back to using a single XL for propulsion: less power, but more control.

Maybe the rechargeable battery keps it a little bit better balanced. You sure love those LA connectors :D I second the motion for a video of the thing in action...

A real beauty. BTW, washing studded parts isn't easy, but it can be done...

Love it - good looking, fully motorized, complete instructions: must build! The problem is with the current overload in the IR Receiver. The Buggy motor is a real power hog and the IR Receiver is designed to short out temporally if too much power is drawn. We had a race with cars with a similar set-up and those 2 seconds of complete loss of control made the race completely unpredictable. I later found out that even using two IR Receivers (one for each motor) doesn't do the trick as the battery box has a similar protection system (don't know a bout the rechargeable battery but suspect it may be the same)

Indeed, the knobs are brick built (round bricks and round tiles) and connected to NXT motors. The only non-lego parts of this MOC are the the light to illuminate the display (maybe some day we'll get a retro illuminated display - keep your fingers crossed) and a sound output connetced to speakers to enhance the sound volume and quality.

I guess this is to do with the music that was added to the video. Have you tried setting your location to somewhere different than Germany?

The NXT-606 *is* LEGO only ;) Another LEGO music related video:

You want to do two diffrent things: transmit IR signals and receive IR signals. For those two different tasks you need two different sensors. HiTechnic has an IRLink sensor that enables you to send messages to the old yellow RCX MINDSTORS brick, send commands to RC train receivers and to PF IR receivers. They also have an IR Receiver which can receive signals from a PF remote control but canno receive messages from the RCX or RC remote control. These are the two sensors you have linked to on the LEGO website.

Nice to see some 1-set-MOCs. From the few pics you show I have to agree the middle one appeals to me most.

If you want rotation to linear check out all the Technic Walker designs - they mostly use just that feature. For the other way round have a look at the tech train forum and you'll see plenty of ideas.

I'm having a terrible sense of Deja Vu... Wasn't this shown on this forum only one or two days ago? No video or LDD instructions then though. The model is certainly worth the attention.

It's a scary dude, but it sure is an original model!!

That explains why I didn't find it. I rarely visit any blogs directly. I normally read them through Google Reader.

I gave up on Brickshelf quite a while ago... :( I miss http://www.nicjasno.com/ which I (used to) visit frequently.

Have you got a link for the blog?

One thing is ability. Another completely different thing is whether this is being done or not. I think it would be a pretty sorry state of affairs if people suddenly decided their models were copyrighted and no-one should be allowed to even copy them without some kind of monetary compensation. We're not making money on any of this (well, at least most of us aren't) and although it is annoying to see people 'steal' MOCs there is no monetary damage. If there were (e.g. if anyone were to 'steal' anyone's MOC and try to sell it) I'd be the first one to want that to be put and end to.

I keep forgetting this forum isn't only Technic, but also MINDSTORMS... I'd like to present my latest build: the dFlex Wall Follower. First a bit of background. Dexter Industries is a fairly new company that produces sensors and switches for the LEGO MINDSTORMS NXT. Last month they had a contest to promote their new dFlex sensor and I was fortunate to be one of two people whose proposals were rewarded with a free dFlex sensor. I've now had some time to work with this sensor and try it out in different set-ups and I'd like to show you my dFlex Wall Follower. Laurens Valk kindly gave me permission to use his Explorer from "The LEGO MINDSTORMS NXT 2.0 Discovery Book" as a test base to which I added a front bumper, and this is the result: There front bumper is really simple and there are a couple of pictures showing how it is attached to the Explorer on Flickr. Of course a robot isn't much of a robot until you see it in action so here's the video: The wall follower is programmed in NXT-G. Dexter Industries have made available two different NXT-G blocks for the sensor. In this program I have only used the first block and all calculations for the proportional control are done with the raw output of that block. However if you use the second block, you can easily calibrate the sensor within a specific range and get a bend percentage inside that range from the second block... something to use in another bot.

Fortunately there is no such thing as copyright in LEGO - I mean: anyone is alowed to recreate anyone's MOCs, MODs or buiding techniques without a legal obligation to any kind of tribute. However, the decent thing to do is to give reasonable credit when due. After all, you'd expect other people to do the same for you, right? If someone does 'steal' your MOC - blatantly copying something and then passing it off as their own - there is a very nice Flickr group you can use to set the dogs on them: http://www.flickr.com/groups/brick-busters/

Thanks for the great review. If I ever had even the slightest doubt whether I should get the set, the only question now is when (and where)
