Part 1 HERE: http://www.youtube.com/watch?v=xRXEc7pB0o0 An unedited hour long video of Dave playing around with the library editor and PCB modules in KiCAD for the first time.
Dave looks through the documentation for the vintage 1980 NEC PCN-1205AH 5kW Analog TV Transmitter that used to transmit the CH7 TV frequency in Sydney
He then tears down the HPA-3696 IF Modulator used in the system.

Part 5 of an interview with Colin Mitchell, the pioneering founder of Talking Electronics magazine.
In this final part he takes us through some old hardware kits, including the TEC-1 and Microcomp computers.
Did you know you can use your frequency counter to detect gravity? You've likely done it before and you didn't even know it!
Dave demonstrates the phenomenon of 2g-tipover on quartz crystal oscillators in an Agilent 53131A frequency counter.

Why do digital oscilloscopes appear noisier than traditional analog oscilloscopes?
Dave busts the myth that digital scopes are noiser than analog scopes, and demonstrates what inherent advantages digital scopes can have over analog scopes in terms of true waveform capture. And also why your analog scope may be hiding important signal detail from you.
Demonstrations of how memory depth, analog bandwidth, averaging, and intensity graded displays can all effect the signal detail you see on your digital oscilloscope.
And how long exposure camera shots on analog oscilloscopes can reveal detail you can't see with your eyes.
Demonstrations are done on the new Tektronix MDO3000, the Rigol DS1052E, the Tektronix TDS220, and Tektronix 2225 analog oscilloscope.
