comment Is there a site where I can put in a set of individual lego bricks (by part ID) and get an optimized list of stores to buy (to minimize shipping)
See also: How can I minimize the number of merchants for given set of requested bricks?

comment Which buildings were based on sets in the LEGO Island video game?
Many thanks for pulling those together and persevering with our "new user limits" - I've added those links into your answer for you :)

comment LEGO Brick Color Palette
We should probably update one or other of the answers on How many different colours of LEGO bricks are there? - however the Peeron list is updated as colours are seen, so it should have them all, sadly it doesn't seem to have date ranges on there for "first/last seen" although you can find one per-part: peeron.com/inv/colortable/3004?ip=0

comment What causes the NXT Error 1055 in LabVIEW?
The error code is listed as "Object reference is invalid.". In other languages this is usually caused when you try and use a variable that is out of scope - I'd suggest checking your variable names.

comment Has anyone automated the LEGO hand sorting process beyond “pawing & piling”?
Hi David, and welcome to LEGO Answers. We're looking for long answers that provide some explanation and context - and not just links to another site - if you could include a copy of your key image that would help immensely (i.e. step 2). Thanks :)

comment Does knolling help or is it just part of the fun?
I certainly wouldn't go so far as to arrange everything perfectly, but I have been known to sort into piles of size and colour - once I know it's a pile of dark green 1x2's that's enough, they don't all have to line up perfectly.

comment EV3 controlled by 8879 speed control through IR sensor
@MichaelVerschaeve - I'm not sure that there is - the HiTechnic IR Receiver doesn't yet have an EV3 block, but their other two IR sensors (the seeker, which looks for IR sources, and the IRLink, which sends commands to other IR receivers) do.

comment Could I do datalogging in Mindstorms EV3 Home edition?
I believe the data logging component is actually a feature of the Firmware for the EV3 brick, in conjunction with some additional capabilities of the main software to load additional modules.

comment Raw RGB data to Color?
@Nick2253 - I think this would be off topic at Code Review: They explicitly don't want questions about "Troubleshooting, debugging, or understanding code snippets." - they go on to require that code samples in questions "work as intended" (but need improvement). It's more on-topic at StackOverflow (I have some code and it doesn't work), but we should be able to answer this here ;)

comment Raw RGB data to Color?
Also, note that HSV and HSL are not quite the same, and instead of calculating V (as var_Max) you should calculate L (as 0.5(var_Max + var_Min))

comment Raw RGB data to Color?
While I think Thaddeus Hughes has the answer it might help if you could also post some sample inputs and outputs (i.e. "for R255, G128, B0 I'm getting H0, S0, V0", etc.) - are you getting an HSV of 0? or some wildly different values

comment Bluetooth communication between computer and nxt using RobotC
Are there any other steps to this? Ideally we're looking for substantial answers that provide a bit of detail - possibly mention libraries or API calls?

comment What are the largest Technic-compatible tires on the market?
While not as big as the ones in the accepted answer, these may be more available due to the larger number of sets they appeared in.

Hi Emily, which phone are you using?

comment How can I rotate an EV3 motor an exact number of degrees using RobotC?
Also - can you post an example of what you have tried - RobotC should support sending specific angles to servos assuming you've configured them correctly...

comment How can I rotate an EV3 motor an exact number of degrees using RobotC?
Is this a duplicate of your previous question - or have you switched from NXC to RobotC? Are you using the interactive servo motors or the medium/large servo motors?

comment Quick way to inventory parts
Hmm - if you're willing to take the time though surely this is a prime candidate for machine learning as well: you train it with some known bricks first and let it build its understanding of different bricks from there ;)

comment Way to build LEGO spaceship with regular bricks
It depends on the scale and how "rough" you're willing the final product to be - here's a Sailing ship built purely from 2x4s

comment How much is my large minifigure retail display worth?
Hi Logan - any chance you could include a currency in your answer - 400-1500USD is fairly different to 400-1500GBP and is very different to 400-1500DKK ;)
