Skelf and safety

This might've been a good entry for tinytuesday, but I hadn't impaled my hand yet.  One of the reasons they make racing cars and wind turbine blades and bicycles and kites from carbon fibre is that it's really strong. With a relatively inflexible matrix, the resultingly very high modulus of elasticity means that when the stuff breaks it tends to splinter, and carbon fibre splinters are small, very stiff, and very sharp.  A lot like cactus spines, in fact.  They go into your thumb quite easily as I discovered (again).

At any rate I squared away a few things at work today and went into the garage for a couple of hours.  It was so cold!  But I tidied up the wiring from yesterday, secured the control box in the correct position and the aux output does exactly what it should do.  The evening ran out before I could make a little rubber boot for the plug and socket but I can do that at the weekend.
