Trundling along nicely, the mark 3 architecture works and this weekend is planned in for building the first 3.1 driver board, which should save a whole 2.4 millisec off each update. Can't test the centre board coz I blew the picaxe but it seems good so far. Another is on it's way from Oz, you know how these things are.

No space laser here, in fact no spare 100W diode-pumped Nd:YAG laser here, much to my consternation.
