# Links to some of my Liberty BASIC pages

Through the years LB has given me a great deal of pleasure, and helped many of my students, young and old, discover the pleasures of programming.

I have been having fun using LB for tasks on the Rosetta Code project site, which shows just how versatile LB is.

All the following links go to pages showing some of my coding, coloured by my interests in applied technology, interfacing to hardware, physics & maths.

My original site, with code for multiple types of LB application, was hosted by RM plc.

It included links to a Rasterbator clone, and an Airwriter version using the Brian Schmalz's 'UBW' USB port; serial links to servo drivers and interfaces; Travesty generator; etc, and disco lights driven from parallel port.

Since RM seem incapable of removing it or continuing to give me access, these pages were moved to this personal site. Any known problems are dealt with on the Errata page. In particular, there is an update of the Travelling Salesman solutions.

An article about the misunderstanding of diodes in circuits. (Word document. Simulations were in LB but now in Spice.)

My Flickr pages.

Creating Orienteering Maps.

A Raspbery Pi ADC in Python.
