Welcome to Eurobricks, Wiggles. I believe there is a rock tutorial in the Historic forum -> http://www.eurobricks.com/forum/index.php?showtopic=100419

Welcome aboard, Arne.

Treasure - check Drink - check Woman -check I would say this is a paradise. Well done.

LOL. Good work. I was wondering what happened to you and your Jar Jar. I think you could deep link a picture or two in your post to entice people to click your link. To see more, click here sort of thing.

Welcome aboard Eurobricks.That's a nice Russian fire train.

Great job. Friends you don't want to be unfriended by.

Cool use of the new hull. Minidolls rulez.

Like Mammoet style?

Welcome to Eurobricks, Sherwin.

A vision comes to me in a dream and then Trial and Error.

Two Power Functions trains. I didn't account for the condition at the end happening.

Interesting. It's going to need cameras for the engineer to see those blind spots but good level cross crash protection.

Pretty good on the outside. Do you have an interior?

For electronics soldering rosin-flux cored solder should be used. Do not use acid flux cored solder or acid flux. Those are meant for plumping work like soldering copper water pipes. Would it be better to desolder the polyfuse from the board and solder in a small piece of wire or flat metal in its place? It looks like it is just surface mounted.

If your thumbnails are too short, you can also use the axle part of the brick separator to pop it out.

Here is the sketch for the train ping pong: /* Train move back and forth between 2 reed switches Channel 1 Blue dr_spock_888 July 17, 2015 LEGOPowerFunctions library by Roland Wiersma */ #include <legopowerfunctions.h> LEGOPowerFunctions lego(12); // IR LED on pin 12 const int reed1Pin = 2; // Reed switch1 on pin 2 const int reed2Pin = 3; // Reed switch2 on pin 3 const int ledPin = 13; // LED on pin 13 int reed1State = 0; // Variable for reading reed switch1 status int reed2State = 0; // Variable for reading reed switch2 status void setup() { pinMode(ledPin, OUTPUT); // Init LED pin as output pinMode(reed1Pin, INPUT); // Init reed switch1 as input pinMode(reed2Pin, INPUT); // Init reed switch2 as input lego.SingleOutput(0, PWM_FWD2, BLUE, CH1); // Start up train } void loop() { reed1State = digitalRead(reed1Pin); // Read state of reed switch1 reed2State = digitalRead(reed2Pin); // Read state of reed switch2 if (reed1State == HIGH) { lego.SingleOutput(0, PWM_FLT, BLUE, CH1); // Stop the train digitalWrite(ledPin,HIGH); // Turn on LED delay(2000); // Pause at station digitalWrite(ledPin, LOW); // Turn off LED lego.SingleOutput(0, PWM_REV2, BLUE, CH1); // Start up train other direction delay(1000); // Pause to ignore reed switch on the way back } if (reed2State == HIGH) { lego.SingleOutput(0, PWM_FLT, BLUE, CH1); // Stop the train digitalWrite(ledPin,HIGH); // Turn on LED delay(2000); // Pause at station digitalWrite(ledPin, LOW); // Turn off LED lego.SingleOutput(0, PWM_FWD2, BLUE, CH1); // Start up train other direction delay(1000); // Pause to ignore reed switch on the way back } } It would work for that. It wouldn't be hard to add additional stops along the way. Just have to keep track of which direction the tram is going. Yup, it also was cheaper to make a Power Function monorail style railcar set than buying Airport Shuttle. Stadler GTW 2/6 by dr_spock_888, on Flickr

Wow. That is really well done. Good luck with Idea.

Not really too picky. I've been pretty lucky with part prints and stickers. I did have to ship back a broken NXT to them after they shipped me a replacement quickly. I think the thing with LEGO is when people start abusing something good LEGO does, LEGO will stop doing it or it will get harder for everyone else.

NIce. Good way not having to swtich to Kadee couplers or to ones that can be locked together with a 1x2 plate or tile.

You could use a graphics program to combine them into one picture. My train sig is a single JPEG.
