The plane, the plane. Master the plane
Recently I upgraded my mill to use a new 1W 808nm laser diode from that
which was removed from a DVD laser burner and I must say its great to
now be marking out my wooden templates for my scale glider at 200mm/min.
The old one just didn't cut it (no pun intended) as it could just barely
make it to 40mm/min.
Marking out now looks like
The problem here is that there were small gaps in the CAD DXF file and
so the laser stopped and burnt holes :(
Once that was sorted I continued and now have the central wing done, all
800mm, and have the remaining 3.2m to go.
I have also done the body frame and feel that I can now do wicker work
as well

Revival of a Raspberry PI
One of my work mates had a ROI that had no working USB or network. He sold.it to me for a small sum.
So when I got home I started to investigate and forms plenty of info on the net about bad joints on the 25Mhz crystal that drives the net/USB chip.
A quick touching with a soldering iron fixed the issue.
I so found that the old "A" series jumper is on the board so that you can just place a pair of solder.shorts and get back to having a single USB port to work with
