I want to know where I can download LDCC (Lego DCC) firmware source, does anyone help me? LDCC is used to control Lego train.

Maybe I have to modify title of this post, because I found one my touch sensor(1/20) is ok, so I can say my RCX is no problems. Anyway, thanks for your idea.

Thanks for your message, I just was in panic because I need those old touch sensors in my projects! Like you said, maybe the rubber is getting thin so that it can't touch to internal wire, I have a idea to put a thin metal on rubber, this might fix touch sensor, anyway I will try it.

I opened damaged touch sensor, but I don't know where has problems...

I don't know why, and I found all my RCX touch sensors don't longer work just moment, and I tried to use bricxCC and brickOS to test them, they are never on even I pressed yellow button on touch sensor. Does anyone have similar experience? do I have to open them to fix? Thanks a lot!

Thanks a lot, though I used a bush to fix axle, but your idea is better. Now my own bogie has a rotation sensor to check velocity, a vertical axle to another rotation on the front of locomotive to check if train on curve, then there is a light sensor to check IR from RCX for proximity. On the back of train, there is a train motor and a motorized uncoupled with touch sensor for coupling or un coupling. On the middle of train, there is it a RCX. This train will run automatic by brickOS program, it will forward in specific velocity even on curve, It will pause if found objects in front of train on straight track until objects removed, it will uncouple car and couple car after sometimes. I will show you when I finish it.

Yeah, it works, but it looks like too short. But I still don't why LEGO SHOP packed 7L with motor set...

Yesterday I received two sets of PF train motor, but I found the axle 7 is too long so that I can't attach Motorbogie, Ornament. Then I tried axle 6 but it seems like too short, what can I do?

Thanks a lot! Is this can be used with PF motors?

I want to buy some PF wheels which has axle hole, I googled but no any results, does anyone give me suggestion, where can I buy such wheels as Black Train Wheel With O-Ring?

Is it possible to put a part on axle of train bogie plate, when bogie plate is rotated, that part is also in rotation?

Is there any figure or image for all of your idea?

Thanks for your advise .

Can you explain for detail? Do you have any figure to illustrate it? I am interested in that.

This is what i wondered, I tried it but no successful...

Great! you fund a bug in my layout, I just modified it, not it is ok as below:

Because I am using RCX and I only have touch, light or rotation sensors...

Thanks for all of your answer.

So I can just use a regular controller connect to this layout without any modification ?

I am planning a project that will be a layout as below, but when I check the electric, td2.0 program told me this layout has a short circuit, I am not sure if this is correct, can you check it for me?

I want to know if someone know how to check if a locomotive is on a curve track? One way is to use a axle to instead of bogie pin, then put a rotation sensor around that axle so that curve track can be checked. Does anyone have any more simple way to check locomotive on curve track?

I just found a easier way to fix it, this way that I don't need to use soldering. I use nail polish to cover wire so that a insulator is out of wire. My soldering is very bad, I think the time is too long and parts might be damaged... Anyway, thanks for your video.

I just pried the back plates both of light sensor and wire connector. Though separate was very difficult, at the moment, this light sensor is good. I found LEGO don't use solder for their wires to electric plates, this is why they used a thinker wire insulator. Next I have to replace this bad wire with a soft one by soldering, i am confident for electric plate, but I am not good at soldering skills, I am afraid of tiny point on the circuit board! Do you have any suggestion or tips?

Thanks, maybe this thread is suitable. I hope that I can get what I need...

I have a nqc program as below, it used RCX IR and light sensor as proximity sensor, it is very perfect. // proximity.c #define THRESH 50 #define MSG 255 task main() { 　　int oldValue; 　　SetSensorType(SENSOR_1, SENSOR_TYPE_LIGHT); 　　SetSensorMode(SENSOR_1, SENSOR_MODE_RAW); 　　SetTxPower(TX_POWER_HI); 　　while (true) { 　　　　oldValue = SENSOR_1; 　　　　start Send; 　　　　if (abs(SENSOR_1 - oldValue) > THRESH) { 　　　　　　PlaySound (SOUND_CLICK); 　　　　} 　　　　stop Send; 　　} } task Send() { 　　while (true) { 　　　　SendMessage(MSG); 　　} } because I want to use brickOS to control my train, how can I convert it to brickOS? I tried but not successful, does anyone help me?
