I do a little programming in VB2010 and for PIC controllers. I wouldn't call myself an expert as it always takes me a long time and I'm constantly learning. I enjoy what I do.

I've completed a few projects.

Tide calculator for the UK
Sony LANC camera remote control - serial and Pic controllers
PIC Pulse Induction Metal Detector
Morse Code through the sound card
Home Maintenance Log

I also do a little web design and maintain my diving club's web site at http://www.esac.org.uk/.
