A Cautionary Tale
Don’t drop the lens when reverse lens macroing! I thought my kit lens was a goner when I dropped it about a metre on to concrete. The front focusing element jammed at a nasty angle. Fortunately the optics were unharmed. I managed to take it apart and free the jammed part. It works, it just sounds a bit different when the focusing motor runs. This is a reverse lens macro with my Canon 50mm f1.8 primary. I managed to keep hold of it this time.

My First Microcontroller
I finally got round to trying my hand at microcontroller programming. Following this instructable it was dead easy. The main problem I ran up against was in the software. On Linux you need the ppdev module in order to have access to /dev/parports. In menuconfig it’s Device drivers -> Character devices -> Support for user-space parallel port device drivers. On Debian you need the following packages: avr-libc binutils-avr gcc-avr avrdude Your user also needs to be in the lp group for access to the parallel port.

Our third visit to Monkeyworld was hot and sunny. Several of the chimps in Charlie’s House seemed to be rather lacking in hair.

Old Tom doesn’t move very fast. It seems just sitting there pulling faces is quite exhausting.
