After a week or so, the mechanised mixer (see below) was modified by suspending it and getting rid of the bracket it was previously taped to. This was, we believe, an improvement both aesthetically and mechanically, and it was gratifying to find that the whole system was remarkably stable with just an engaging skerrick of wobble as the crank re-engaged with the handle on each revolution. Which just goes to show that our previous mental analysis of the forces had not been so great.
But now the mixer is offstage again. In its place is a reworking of the astable capacitor/relay system with strobe effects in the fan. And a counter. That doesn't really describe it too well; guess you need to see it.
Another discarded microwave oven has been collected. We have plans but don't expect to see it in the window box any time soon: it's too big. And we have taken delivery of some new (not recycled) microwave motors and other components. This does not represent a policy shift, it's just that have no need to be precious about reuse and recycle.
