Details of Some Current and Former Hobbies

Digital Electronics

Robotics

I've just finished constructing a Sumovore robot kit and am modifying its C program, written for the AVR micro-controller, so as to extend its capabilities. I have come up with a runtime debug tool which displays a binary code and pauses for a Continue button.

Computer

Assembled a non-working Apple II clone (from a kit with two missing traces). Fixed it with the help of a hardware monitor which I designed and built from a Multiflex Logic State analyser and my custom interface card, so that the latter would control the Apple's CPU. Normally an analyser just records the last few hundred signals after a given location is reached. I fed back the ‘location found’ signal from the LSA to the interface card and let the user step thru operation of the CPU with a push-button.

TTL

Designed and built (wire-wrap) a TTL chess clock.

Flying

Owned a Cessna 140 for nine years, including about 400 hours of flight time.
Flew (solo) from Toronto to California, via Vancouver, and back by way of Albuquerque.
Also flew from Toronto to Oshkosh and to Florida.
Logged about 80 hours in gliders; including a wave flight to 25,000 feet over Pikes Peak and a 5 hour duration flight in Pennsylvania.

Chess

Have played in chess tournaments since university.
Currently have an 1800+ Standard rating on the Internet Chess Club and an 1850 USCF rating.
Usually I play 2+12 minute chess on ICC and 15 minutes over-the-board.

Cat Photos

Here's some photos of my cats. They aren't the best technically, but they do justice to the cats' personalities. All were shot in available light, mostly indoors at 1/30 sec on Tri-X.

This is Plato, so called because he was intelligent and I lived in a Greek neighborhood at the time.


This is Hector, he was brave and I still lived in Montreal Nord. Of course the original Hektor wasn't Greek, but he was fighting them.


I wanted to photograph Plato in all his moods, but decided I would never finish!

Here's a great sequence of Hector in action.
He goes exploring behind the bathroom wall, which is missing its soap-dish.

He's getting out, but Plato decides he doesn't want to go in himself.
