What's not to like ? Apart from a slightly mawkish family-friendly plot, which is best ignored.

Learning new to science

I have discovered a new thing:

When drilling through two bits of thin brass, holding them together to make sure the holes line up properly, one should not have any of the holding fingers under where the drill is going to come out.

Even when that is on the far side of the wooden benchpeg, up at the end where the drill will go through it in half a second and continue into unresisting fingertip.


Repeat after me, one million times:

! is not bitwise NOT. ! is not bitwise NOT. ! is not bitwise NOT.

This has been a public service message from the Bit Twiddler's Association. Thank you for your time.

Dorkbot fun in Bristol this afternoon

If you're in Bristol and feeling feckless this afternoon, you might want to come by 100 Stoke's Croft.

Dorkbot and Draw have the use of an empty shop. There will be drawing robots and drawing workshops. In the usual Dorkbot style, some of the robotics is not quite finished, but there's still 4 hours before opening time, so I'm sure it will be fine.

There will be more of the same going on on the 27th - possibly with more working machinery - but I won't be there for that one.

Hours are 12-4, at 100 Stokes Croft, BS1 3RJ.

Metallurgical learning

In today's lesson, we learn that silver/copper, 50/50, comes out looking remarkably similar to tin/copper, 10/90.

In this way, an expensive metal can be used to simulate the appearance of a cheap one. Ho hum.
