@Crusty: You probably have the measure of it.

12 inches, but I don't use it as a rule ... I'm sorry, what were we talking about? LOL

@Crusty: Mrs Crusty does not allow me out that much...

She tells me that she has to take you everywhere twice ... the second time is to apologise for the first :-)

@Max: With the thousands of miles of MICC I accepted for the fire alarms at London Underground post Kings Cross Fire, I almost became a world aclaimed connoisseur of MICC cable installation.

I can still walk around the sations and say which crew installed a particular section, just by looking at the way it is dressed into the building fabric. I think LU took the whole output for England for two years, some say the total length used would reach the moon.

If you are going to downgrade a cable then you have to be as good as the men installing, so I learnt to dress and terminate MICC. The Japanese joke that MICC is the English plumbing electricity, it has to be installed at site and can not be pre-constructed in a factory.

I have got data rates of over a Meg across a kilometer of MICC which considering it was not designed for such use is amazing.

But correct after working 7 nights a week for two years installing/accepting the LU fire alarm systems Mrs Crusty does not allow me out that much.

@Crusty: Terminating and dressing multicore mineral insulated copper clad cable is a strangly satisfying past time.

You don't get out much, do you? (LOL)

The finalists must make "solder chains"

To really find the best of the best, the finalists need to solder 0.7mm (or thinner) soldering wire to itself ie make a loop. Then add another and another to form a long chain. It can be done; I was an expert 35 years ago. Using a modern electronic temperature controlled solcering irons is cheating!

Just fired it off at the wire end and sploog ends into a mug of acetone.

Power electronics lab style - we went thru several CO2 extinguishers per week.

The Cooner was for for large air cored toroids - just don't forget the anti-poloidal turn!

Having over 24 TO247 mosfets blowing up behind your back was a wee bit of a regular nuisance, and that was regular. Not my design but an inherited inverter that was sacrosanct. I came up with an cheaper IGBT version, ~200kHz switching, ~100kHz PLL resonant ZVZC switching and then quitely walked away from that job. That was 18 years ago.

As to why Radiologists' wanted 150kV @ 80kW, no idea. A zoo VET might need such a thing, but for humans?

How about snapping insulation tape with your fingers?

I guess Max should be organizing a triatholon.

NEXT UPCOMING BROADCAST

Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
