WESTECT II

Monday, January 30th, 2012

Now that the second incarnation of WESTECT ATP is complete, I can return to my “normal” life. Almost 7 years ago, Digressoft was asked by the head of Invensys Rail Australia (previously Westinghouse Rail Systems Australia) R&D to perform a feasibility study into a new generation of WESTECT.  Several components of the current hardware were […]

RepRap

Wednesday, November 16th, 2011

Friends decided to dip their toe into the 3D printing revolution by putting together a RepRap open source (both hardware and software) device.  Being hardware technicians, they became a little lost when the software didn’t behave as expected.  I helped out in my spare time making modifications to both the Arduino firmware on the actual […]

TemPIC

Monday, November 15th, 2010

This is another of those fun projects done with friends. A friend came into possession of a box full large (200mm) 4 digit 7-segment displays with a PIC processor to drive them.  After some discussion we decided to make wall thermometers out of them.  He attached a button and a temperature sensor and I threw […]

Instrument Panel

Wednesday, September 14th, 2005

The motorcycle instrument panel has finally been fitted to a motorcycle! This project was done “for the fun of it”.  I has taken a couple of years but all done “in our spare time”.  A friend designed and built the hardware to my specification and I developed the software.  The panel consists of two rows […]

JBug11

Sunday, March 14th, 2004

During development of the motorcycle instrument panel, a remote debugger for the Motorola 6811 micro-processor was needed.  As this was a fun project, I didn’t want to spend heaps of money on fancy tools.  A web search turned up an open source Window based debugger based on Motorola’s monitor protocol.  I need to make a […]

WESTECT (continued)

Saturday, September 13th, 2003

Well old projects need maintaining. I have been returning to Westinghouse Rail System from time-to-time over the last 7 years as a part time consultant to investigate and assist the small remaining team to repair defects in the WESTECT ATP system. During that time there was one major upgrade to integrate the on-board sub-system to […]

Automatic Train Protection

Tuesday, December 13th, 1994

After five years WESTECT goes live and it is time for me to go back and do some more study! WESTECT, produced by Westinghouse Rail System Australia, is one of the first continuous Automatic Train Protection (ATP) systems in the world.  Designed in conjunction with and for Queensland Rail for their main coastal route.  ATP […]
