As no one else has posted nominations for May yet - I would like to put forward the 5x5x5 LED cube by f_petrini:

What do people think?

I'll second that.

I was wondering what the biggest LED cube was, this is a possible contender:

How about XMOS sponsoring a project to build the biggest one? It could go in the Guinness Book Of Records.

Thats a nice idea, id hate to be the guy that has to solder together something like that tho.

Oh and it would have to be quite a bit bigger than that

Its not really cube shaped but i guess it qualifys.

That is indeed a beast!

In you opinion Leon what size do you think is achievable if this was opened up to the community?

Something that utilised the parallel nature of XMOS devices could be cool too eg using a few XK1s or such to drive sub cubes to make up the entire cube so to speak, thus modularising the situation into small manageable chunks.

Maybe if it were a community project people could make a sub cube and then combine them to make the bigger cube as they could be all running community code? I have never made one myself so if that is silly let me know!

I haven't a clue how big it could be, but using XMOS chips should simplify things.

I've never built one either, but I'm designing a PCB for Fredrik's version. I'll probably use red LEDs.

I think that partitioning it into blocks, each controlled by a different core, is probably the way to go. A single XC-1A with four blocks might be better than using XK-1s. Your ideas of using separate blocks built by different people should work, as everything can be synchronised in the software, as is done with LED tiles.

Im sure that controlling that 16x16x16 cube would be a piece of cake for a xmos chip. The man problem with LED cubles is the massive number of LEDs needed, plus they all need to be soldered to that wire framework. Meaby someone should try doing the propeller display in 3D. Insted of just putting 1 line of LEDs you could use multiple lines placed further back to get depth to it. This should drastically reduce the number of LEDs needed. Also the accurate timing of many LEDs is a perfect job for a xmos chip.
