Well, my daughter's water spraying alarm clock got nowhere - not helped by me fritzing the pump the day before the competition!
My next project will be an LED cube. I'll be starting small - 3*3*3 single colour to get my eye in, but ultimately I'd like to do a 7*7*7 (or maybe 9*9*9) RGB like this one.

The good stuff starts 1 minute in - it's the best home-made LED cube I have ever seen, although you can buy a kit and just assemble it.
There are plenty of hints and tips out there for smaller cubes which I will work through, however I am also looking to the future and would appreciate your thoughts.
** If I'm using chips to enable more outputs than the picaxe provides I don't need to use multiplexing or charliplexing, right?
** Looking at that video and combining that with my very limited knowledge of electronics, will a picaxe be fast enough to switch the various lines on and off to create similar effects? It uses a PIC16F688-I/P chip which I guess does not have the overhead of Basic interpretation?
** For program memory, can a Picaxe handle what is required? I'd like to have a pre-programmed section - say the waves or upward rain in the video - but also have a randomly generated section, then finally loop around the lot.
** If there is a chance that the program memory is not enough, I'd like to design the circuit to be able to read from a memory card - I could store the pre-ptrogrammed stuff in there - can you point me in the direction of threads here which cover (simply!) how to write to and read from a memory card or chip?
Many thanks,
DDJ
