Actually Ken, I did read the earlier posts a few days ago (or whenever it was). I was very surprised with the big difference between 1 metre and 1.3 metre. Maybe someone else can explain that, but it's odd since it should be a linear relationship?
Still, the 15V supply won't be a major problem, you'll just need to add a suitable dropping resister for your fan. We can work that out - but you sure need a multimeter working on the job! I'm hoping to come up Friday night - it's sort of 50:50 at the moment. I'll bring my meter, some leads, and we'll check things out - if it can wait that long? (Remind me later in the week!)
