(...) Swiss Chalet in Etobicoke is closing for six months for renovations. For January, we'll be at Mel's downtown. I'm going to mention once again, that I don't want to see anything larger than a shoebox at rtlToronto dinners. It's an inconvenience (...) (22 years ago, 30-Dec-02, to lugnet.org.ca.rtltoronto)

(...) I also blew apart a Commodore 1084SP2 14" NTSC preview monitor by feeding it bad sync off my edit card. Any ideas? I presume flyback circuitry is gone. Calum (22 years ago, 30-Dec-02, to lugnet.org.ca.rtltoronto)

Hey folks, John Guerquin came by this afternoon and we went over to the Home Depot, buying some 1.5" PVC pipe and some 45 deg joints. Total cost for 12' of pipe and four joints? $10- tax inclusive. Anyways, we decided to build some ideas for pipe (...) (22 years ago, 30-Dec-02, to lugnet.org.ca.rtltoronto)

If you'd like, I can take a look at it. Admittedly, monitor/tv's and I don't get along too well - I bat about 50% repair rate, but I can take a stab at it for you. Just keep in mind that I've got school starting in January and any montor repairs (...) (22 years ago, 30-Dec-02, to lugnet.org.ca.rtltoronto)

(...) Th - Time signal is High Tl - Time signal is Low Tt - total time ------________ Th Tl <---- Tt --------> Matthias Jetleb P.S.: Th/Tt is defined as the duty cycle, expressed as a percent. Therefor: Th=2ms, Tt=3ms = 66% duty cycle. This is (...) (22 years ago, 30-Dec-02, to lugnet.org.ca.rtltoronto)

(...) It doesn't matter. DMM's are not good at measuring pulsed signals. (unless you have one of the more expensive true-RMS meters which can calculate the average of a non-sinusoidal waveform. You really need an oscilloscope for this. (...) It will (...) (22 years ago, 30-Dec-02, to lugnet.org.ca.rtltoronto)

It is indeed PWM. I got out my oscilliscope and checked it, and here are the results I got: At setting 1 (closest to off): Th: 1ms Tl: 2ms Tt: 3ms 9Vpp At setting 2: Th: 2ms Tl: 1ms Tt: 3ms 9Vpp And at full on, it's just 9v DC. (...) (22 years ago, 29-Dec-02, to lugnet.org.ca.rtltoronto)
