If you only need to convert values by hand, then you can use this tool: colormaid.com/color-conversion

comment Identifying Lego set from 1980's
Yes, I found that Brickset doesnt show it too, that's why I turned to Peeron, where I found this set.

You can see the cut hose technique in other MOCs in the series, especially here and here

I am not so sure about it, but could it be flex hose cut to size? bricklink.com/catalogItem.asp?P=78c02 You should probably ask the creator directly :)

At the first one you can clearly see the difference in stud size caused by the different distance at the corner in the top.

comment Is there a way to set a flat plane at an angle to horizontal of less than 22.5 degrees, but more than 0?
I don't know of any pieces that achieve exactly such an angle, but you can build a frame that provides one. For example, you could alter this structure to result in a slightly different angle from 90°: eurobricks.com/forum/index.php?showtopic=94689 I've also found this simpler, but less sturdy solution: dagsbricks.com/2013/11/lego-techniques-on-angles.html

comment Connection between two NXT bricks
A long time ago in an university club we once managed to hack an RCX cable into an RCX compatible LED, built a frame to mount it into a LEGO structure, wrapped a clear flexible plastic "wire" in tinfoil and duct tape (to minimise light loss) and built another LEGO structure for the other end that held an NXT light sensor. After a bit of programming we could send information from the RCX to the NXT via the optical cable. the only downside was the speed: we could only manage about 1 bit per second. Maybe someone could improve on this concept?
