- G'day beamers. Last week I took the plunge a bought a pc based oscilloscope
from the states. Its 2-channel, 65 MHz, about $700 canadian - alot of money,
but in my mind worth it...
Anyways, I recall seeing a discussion about a course in beam on the list not
too long ago. I'd like to get this organized, with the help of some of you.
With a scope in hand, and course material proposed, I think the community
could learn alot together through a project like this. Some people are
happy just to build the bots, but I think there are alot of people who want
to learn the fundamentals.
If there were other people who own (or have access to an oscilloscope), we
could all run the course together, and share observations and discussions,
and come up with good explanations of the circuits under study for the rest
of the community. The results and findings would be published on the web.
I'd suggest one lab per week, and an organized online chat or something to
- resistors, caps, inductors
- transistors, diodes, 1381's etc.
- inverter chips, motors
- solar engine
- others (ideas??)
- chaotic circuits
- coupled bicores
Some of this stuff is already on the web (scope shots of bicore for
example), but I'd be more intersted in playing around with the circuit, and
posting the results, so people can learn how different components can affect
Feedback appreciated - let me know what you'd like to see. I'm probably
going to do this anyways, but it would be much more interesting to get
several people involved in the analysis and discussion (particularly for the
complex circuits). (Wilf, Bruce... you know who you are ;)
P.S. Eric Seale was nice enough to put up my analysis of the sensorless
wheeled reverser that ran a thread back in july. Its at:
