“A master in the art of living draws no sharp distinction between his work and his play; his labour and his leisure; his mind and his body; his education and his recreation. He hardly knows which is which. He simply pursues his vision of excellence through whatever he is doing, and leaves others to determine whether he is working or playing. To himself, he always appears to be doing both.” - Yvon Chouinard

GoPro Projects

GoPro Time Lapse Controller

I received a GoPro camera as a Christmas gift to use as a helmet camera to take photos and videos during my paraglider flights.

An interest in time lapse photography led to me hacking the camera interface and designing a powerful controller accessory for GoPro cameras.

Instant demand for the controller led to the creation of cam-do.com, a web site offering solutions for GoPro cameras.

As sales grew, cam-do.com evolved into a real business, despite my best efforts to keep it small. Professional photographers and videographers embraced the cam-do.com solutions.

VE3SUN DX Monitor

VE3SUN DX Monitor

In 1989, I began a project to collect and display DX spots retrieved by packet radio from a DX Cluster in Northern California.

In 1993, this project evolved into DX Monitor and was offered as freeware. Since then, the program has been continually improved and expanded. It is now used by tens of thousands of hams in over 150 countries.

DX Monitor is a Windows application.

Stony Lake Cottagecam

Cottagecam

In 1997, I installed a camera at our cottage on Stony Lake and created a web page called the Cottagecam.

In the summer, there are now 5 cameras put up by various neighbours showing what the lake looks like to those not lucky enough to be here.

Weather forecasts and lake temperatures are also shown on the Cottagecam Page.

Dia de Muertos

Confusing illusions. 3D stereograms. Mathematically generated sculptures. Op art. Dark visions.

From time to time the muses encourage me to manifest some of my artistic visions into physical form.

Microchess for the Kim-1

Microchess

Microchess for the Kim-1 was the first commercial game for home computers. After six months of development, the first copy was shipped on December 18, 1976.

In preparation for the 2002 Vintage Computer Festival, I powered up the same Kim-1 used to write the original program and loaded Microchess into memory.

The program and data required all of the Kim-1's memory - 1K. How things have changed since then!

VisiCalc and Personal Software

Microchess

On April 8, 2003, Dan Bricklin, Bob Frankston, and Mitch Kapor gathered with Charles Simonyi to speak about the Origins and Impact of VisiCalc.

This got me thinking about those early days and my own first encounters with the program in 1978.

I was lucky to be able to use VisiCalc for several months before it was introduced to the market. There were even a few bytes of my code in the original Apple ][ version.
