Good point. I checked it with a 7755 from my showcase and it doesn't match nicely: the green ends approximately one stud higher than the lower end of the door of the 7755 loc. So if I want to use the 7755 and I want the colours to continue nicely I have to get rid of the doors in the 7755. The problem with the 7939 is that its windscreens don't come in white :( I could use the windscreens of a 7755, but that means that I have to get rid of the diagonal parts in the nose of the 7939. And these parts just make the loc look cool if you ask me. I don't need the weight bricks since the train is running a 9V track (all 9V trains don't have the weight bricks anymore) and a 4 wide nose isn't a problem either since I don't use PF. I guess I'm gonna stick with the 7755 as a base but I'm going to remove the doors so I can make the colours run at the full length of the train...

Thanks! Good advice about the yellow parts, I'll have a look!

My collection of Octan tanker wagons is growing and I want to have a special locomotive for them. I have two kinds of tanker wagons: the ones that come with the 7939 Cargo Train: and some custom-from-the-internet-stolen-design: The locomotive doesn't have to be big or special so I was thinking about a classic 7755 design: But I'm stuck on the colour scheme. The lower horizontal grey layer on the 7755 will be green in my version. Above that will be a layer of red plates. And all the red you see on the original 7755 will be white. But I'm stuck with the roof! Should it be white, red, grey or green? Or do you have another cool idea?

I really like the red shunter! Too bad you didn't build it. Got the LDD? Maybe I'll build it for you ;) I love the workshop too!

Very cool done, nice job!

In my opinion still the best Pneumatic set ever! And it was even my first

I love pneumatics and do a lot with them. See also my YT channel. The system has more power that LA's but it cannot be regulated. You could regulate the speed of a cilinder by squeezing the tube to the cinlinder a bit but that's it. I don't think Lego will ever make regulated valves for Pneumatics: it means that you need some kind of precise pressure control also and that will be to large/expensive...

Really great. Very detailed, unbelievable great job!

When I was 6 years old I built trains without a problem. I don't think younger builders will have problems with a multiple-piece nose..

Really cool thought out-of-the-box to use a monorail motor! Great job! I wanted to build my own turntable with Arduino as JopieK stated, future project though...

My girlfriend is just supportive. Sometimes she thinks I'm out of my mind when I order stuff worth €300 at Bricklink (I'm not really into sets, but I like to build my own technical thingies) but when she sees me building/creating/programming my robots and automated trains she is just amazed how I come up with the ideas and how I'm able to make it all work in the end. By now when I'm working on something she's really curious in what I'm building and asks me also things like "did you solve the problem that you were working on last week"? Can't complain I guess! Edit: she just doesn't like it when I need to free the whole living room for a train-project during the weekend though...

The HE is much heavier and has two motors, that's the reason why it kept going a bit longer than the rest :)

I noticed only the surviving guy when I was editing the video

One could scratch the bricks, but damage them in a way that they're not usable anymore: very difficult I guess. Especially with some trains which have relatively low speeds. Maybe at 50km/h or something! Since the track was quite long (the distance was needed for the heavy horizon express (with two motors) to get up to speed) I had to put 12V on the rails. When I put the power on, the result was a lot of spinning wheels before the trains started moving

While building/soldering/programming on my latest train automation project some trains crahsed into each other. So I came up with the idea to make 6 train frontal crash. Doing so, I needed to isolate some parts of the crossing, otherwise the trains cannot drive into each other. See below the result ;)

Wow! It also looks very steady and strong, well done!

How do you power the thing? I mean, you have loads of NXT motors on it so you'll need loads of connection ports too. And what are these connections ports connected to? All Lego or did you solder something yourself? And why have you chosen the NXT motors and not for example the XL motors, which are a bit cheaper? No critisism, just curiousity ;)

It looks amazing! Are you gonna ride it outside? :D

Are new parts from a different mold that don't yellow that fast?

How much does it weigh already?? 40kg? 50kg?

That's the alternative program that I can download into the controller ;) I know the problem. I use an HMC6352 compass module and I have also encountered lots of problems. The trick is to navigate on your furniture (distance measurements are very acurate) and make the robot drive short distances between the compass measurements. Doing so, you can more or less make the robot go towards the spot you want it to go...

Let's just say I've put some effort in it to make it work ;) The hard part has been accomplished, I think I can manage to write a simple app to complete the whole project :)

I finally got time to continue with this robot! This time the challenge was to grab multiple cans/bottles from the fridge. This means that the robot has to store the cans or bottles somewhere, to get its arm free to get the next can. I first came up with an extra robotic arm on top of the robot that grabs the can from the arm that reaches into the fridge. This second arm could place the cans behind the robot. But I found out that the cans are quite heavy and I would have to use a big megablocks crane to be able to move the cans, which would add too much weight on the robot. So I thought about an extra arm below the first arm that reaches into the fridge: But I found out that also in this way the cans were too heavy, making the pneumatic cilinders extract on high velocity which resulted in less air pressure in the grabbing mechanism which let loose of the can. So I needed to come up with something else. And then I came up with this... ;) In theory it can now bring me drinks from the fridge. Now I have to write an Android app in which I select which drinks and how many. I've never programmed an app before so it'll take some time :D

If I have guests who want to sleep over I have a problem In front my beer serving robot: one of the current projects I'm working on. The closet on the left is full with Lego, the closet on the right (just visible) is full of electronic stuff...

This is very impressive! Got room for a GPS tracker?
