comment What electrical contact material is used for PF Connectors?
I don't know the specific material, but it's likely nickle or aluminum. You can't go wrong with those. If you want to the best material, you would probably want to look into plating.

comment Quick way to inventory parts
Why do you need to inventory the parts? Is it for custom building purposes? I'm also curious what programs you've downloaded, and what specifically you found undesirable in each one.

comment EV3 FLL Question “ outside the box ”
You'll need to clarify some things. First, how are you powering your robot arm? What gears are you using? Have you tried other gear ratios to increase torque?

comment Are there LEGO compatible CAD Files For Injection Mold Manufacturing?
Manufacturing LEGO-compatible items does not open you to litigation. Manufacturing patented items would. Considering that most of LEGO's patents expired, especially on their basic bricks, that shouldn't be a problem. As long as you don't infringe the LEGO trademark, you would be fine.

comment Building a 45 degree brace
If you are just going for something aesthetically close, and not load bearing, why do you need the hinge piece on the top? Just push the long hinge plate up in to the "awning" and then your problems are solved.

comment Two-state clicker button
If you are referring more specifically to the pen mechanism, you are looking for a bistable cam system. You can, of course, also search for pen mechanism, which gave me lots of pretty pictures from Google.

comment Two-state clicker button
The technical name for what you're looking for is a latched push button. You might try latching instead of latched, and you might try switch instead of push button, but switch will also give you a lot of toggle switch results, which isn't what you want.

comment How is this brick attached to the pregnant minifig?
@Mr.ShinyandNew安宇 How close are they to fitting? Would a small amount of modification allow them to fit? That might be what we're looking at.

comment Are there LEGO compatible CAD Files For Injection Mold Manufacturing?
To clarify, are you trying to get custom pieces created, or custom sets created? If pieces, the LDRAW files are grossly insufficient. You'd be better off taking 3D scans of the LEGO pieces as a start. If sets, look at what Brickmania does: buys bulk new LEGO, and then repackages it into their own boxes with their own instruction manuals.

comment Programming sensor to follow light
This is a duplicate of your previous question. You shouldn't open multiple questions to solve the same problems. Update your existing question and respond to some of the questions in the comments and you will get a better answer.

comment How to use Power Functions with Mindstorms EV3?
As of Nov 2014, the top link doesn't work. And, honestly, I don't think this was ever a valid solution.

comment How to program light sensor to follow moving light using NXT
It sounds like you are unfamiliar with how the light sensor works. First off, it's not directional. Secondly, it detects all light, including ambient light, so your LED may not be bright enough to even register on the light sensor.

comment How can I prevent my train from derailing?
I'm wondering if the flex track is causing more problems than it fixes. If you allow the track to move with any vibration from the train, sure, the track may not come apart, but that means that the track is also no longer dampening the vibrations from the train, which could be allowing the train to jump the track. Non-sequitur: maybe you need to add some more weight above the front axle. Try something like: bricklink.com/catalogItem.asp?P=73090b

comment How can I prevent my train from derailing?
So, is the problem that the train is coming off the track, or the track is coming apart? I'm not sure what you mean by "...the whole things falls down." Also, what happens if you don't have the flex track?

comment How can I tell which LEGO minifigure I found?
A picture would significantly help identification. Also, your minifigure may in fact not be one figure, but a composition of different figures. We are talking about LEGO after all.

comment How many ways can six 8-peg lego blocks of six different colors be combined?
@Mr.ShinyandNew安宇 is right. It's difficult to guess how many different brick configurations are radially symmetric. However, it's safe to assume that the number is fairly low, because the only possible configuration would have to be 90 and/or 180 degrees rotationally symmetric. 90 degree symmetric sets would have 1/4 as many combinations, and 180 degree symmetric sets would have 1/2 as many combinations.

comment Chinese Knockoffs?
Also, depending on the laws in your area, you could be complicit in the credit card fraud by accepting a package in this scheme. At the very least, you may owe the defrauded individual the value of the LEGO set you've obtained as a result of the fraud. As in, the full paid value of the set. And the only restitution you would have would be to go after the fraudster.
