Loads of servos!

Just a quick post showing the latest version of the USB servo controller board, driving six independent servos at a time (it was going to be eight, as we'd originally ordered six servos off eBay to go with the two we've been testing with. They finally arrived yesteryday, but two of them don't seem to work properly - the servos chatter and sound terrible, whatever position they're moved to - so we've left them off the video.)
But as a proof-of-concept, it works pretty well:


The two (older) servos on the right seem to move in the opposite direction to the smaller, newer 9g ones. Maybe because they're by different manufacturers? Or maybe they're meant to be mounted the other way around - who knows??

For anyone interested, here's the full script of the animation being played out:
