You can separate them with commands like AND and a bitshift. AND is 1 if two input values are 1 (and not 0), otherwise the AND is 0 (0 AND 1 is 0, 1 AND 1 is 1, 0 AND 0 is 0). bitshift shifts the values of a variable a given amount to the left or to the right (0001 lshift 1 is equal 0010 (or 0011, depending on the implementation)) A pseudo-code would be: int rbg = 110011001100b (4 bit R, 4 bit G, 4 bit B, the output of the sensor in binary. You have to check the actual datatype/ bitlength of the output) int val2 = 000011110000b (1 for the bits of G, again assuming that one r/g/b value is 4 bits long) int val2 = rgb AND val2 (it should be a bitwise AND. Now the content of val2 is 000011000000) int val2 = val2 rightshift 4 (Now the content of val2 is 000000001100, again assuming that one r/g/b val is 4 bits long) I don't know if python supports binary inputs. You'd have to "convert" val2 to HEX if not. The commands for rightshift and AND are probably not AND or rshift. You should be able to find them on your own ;)

That doesn't hold true with the breakout option of the ultra sonic sensor of SPIKE Prime. That has a breakout option on purpose. In addition to that LEGO has to calculate with very stupid things like users that hold the cable into a basket of water (which shorts the cables) etc.

I wouldn't be too sure about that. I don't really think that the market is big enough for 3 different products in such a short age span. The spike prime hub comes dangerously close to the computational power of the EV3 and making a "more advanced" version of the EV3 would just raise the production cost. They are too expensive for many kids already.

@Ender3Guy That comparison isn't completely fair. Functionality with community supported programming languages gets lost with every new mindstorms generation. You loose 2 ports but the new ports can be either input or output (you can now create a model with e.g. 5 sensors and 1 motor which wasn't possible with ev3). In addition to that it's plug-wise compatible with all the other powered up parts (tho software support might be lacking). On the other hand the EV3 already had the wireless programming option.

You're welcome :) Yes, the boost hub gets remote controlled, too. You can see that if you use any of the sound effects - they get played by the tablet; not by the hub itself. The spike prime has internal memory. I think that both should be possible, a remote control by the PC and standalone apps. The hardware power of the spike prime should be somewhere between NXT and EV3.

The hubs get remote controlled.

Yep. They also added support for the boost parts (move hub, medium servomotor and color- and distance sensor) for the programming part.

Do you know how good it works with 3rd party accessories and older stuff (e.g. RCX motors and sensors)? Can you use wifi or bluetooth to upload programs? The documentation only mentiones USB. Can you use other USB hardware like the dimensions toypad which is possible with EV3DEV?

Did you read the specs of the hub? It seems to be somewehere between NXT and EV3. By far not enough to process images of a camera. The only option would be something vision commander like with a PC.

It's got the same target audience as mindstorms (middle school/ 6-8th grade). Kids in that grade should be able to differentiate colors. I'm pretty sure that their gender inclusive statement is the actual reason for the different colors.

The medium motors have a "0" position like the power functions servo motor. It looks like it can directly go to a given degree. Idk if the big ones have them.

You can look into the block if you open it with a double click or if you browse to it with the first configuration tab of the project.

There are 2 sizes of the motors. The set seems to come with 2 medium and 1 large ones but the additional one is a large one.

I think that you would have a very massive space problem because there is no space left for motors if you try to put the boost hub or the ev3 into it. But there are bigger wall e builds with the ev3 (and maybe boost) and I think that there is a power functions version of the ideas wall e.

BTW for everyone looking for the programming block for the IRLink (although it's buggy): https://www.dropbox.com/s/ixw4gbx9uipeprq/HTIRLink.ev3b?dl=0 I think that there is a second edition of that block but it seems like I can't find it.

There was a "Out of the Box" community challenge for the EV3 when it first came out with the same rule. I built a Number five/ johnny 5 like robot back then: Brickshelf gallery with a LDD file and more pictures: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=534933

I'm still pretty satisfied with the backwards compatibility of lego. There are adapter cables for all the recent wire systems (apart from PUP but hey, that might get one in the future, too. They don't sell the PUP parts seperatly yet). It would be great if NXT and EV3 could communicate directly without 3rd party software but at least the sensors and motors are compatible (with the exception of the IRLink and the 9V adapter cable). Regarding EV3 and PUP it's again a hardware limitation - "normal" bluetooth VS BLE which wasn't that popular back then in 2013. But you can control PUP if you attach a BLE dongle to the EV3 and use EV3DEV. I think that both, the 9V adapter cable and the IRLink work with the EV3 if you use EV3DEV. And then there is the stupid AutoID function of the EV3. I have the impression that the single reason why the old adapter cables etc. don't work is the AutoID option.

Why infamous? I think that it's pretty good apart from that EV3 support is broken. But it has the most complete IR support when it comes to the lego IR protocols.

Thanks, that's probably what I wanted. I think that there is no official 1.04 and 1.05. BTW I also found 1.04: https://wiki.qut.edu.au/download/attachments/171509415/ev3-edimax.bin?version=1&modificationDate=1383238867000&api=v2 The hitechnic irlink sensor works better with these versions (at least 1.04)

Does anyone have a backup of the lego mindstorms 1.04 or 1.05 firmware? Can be both, education or retail.

Regarding the avaiblility of PUP parts: you can get the M-Motor from lego education retailers.

Actually there were 3. Don't forget the hogwarts express. But yeah, the last creator expert train came in 2016 (the winter holiday train). It might actually be possible that we'll get yet another train next year.

Personally I'm surprised that many people motorized the tender. Sure, it's probably the easiest way but I don't think that it looks very good. Here's my current (not final) way as a reference although I plan to use powered up parts in the future so that I don't need extra space for the IR receiver. The M-Motor is in the cabine.

Just a wild guess: maybe the remote can read the battery voltage?

Hmm. They probably stay at their current 9V-based system because motors driven with 9V seem to work good for the purpose. That means that they will stay with 6 batteries for the train base. That leaves 4 batteries for the remote. Seems like the new remote is confirmed. The last "upgrade" for the IR based remote was from 3 AAA batteries to 2 AAA batteries in the EV3 remote. It more or less confirms that we will get a new remote system (which consumes about double the enegry of IR).
