Another prototype

ven if it is not very solder-able. I learned that from model railroads. T he brass or copper plated tracks (which ever is the orange/yellow looking s tuff) oxidize and don't conduct until sanded a bit. Nickle plated tracks s till oxidize but conduct anyway.

manage to plate it that way. Some tricky chemistry maybe.

It isn't exactly tricky to get reducing conditions at an electrolytic elect rode.

NiO forms a coherent layer on nickel, protecting the metal against further oxidation (like aluminium and chromium, and unlike iron) so there wouldn't be a lot of NiO there to be reduced back to the metal.

What they actually do is anybody's guess - electroplating is a black art, o r - in more rational language - it involves a lot of proprietary knowledge.

Thanks for the pcb offer, but no thanks. I'll talk with the pcb place and get gold over nickel.

Re: soldering to nickel. I think I've done this in the past. Soldered onto nickle plated contacts, and nickel plated brass stand-offs. (Maybe with my "big ass" Weller soldering gun.)

There are scads of electronic gadgets used around food, like controllers inside ovens and toasters and mixers. Unless they are in direct contact with wet food, any ROHS board should be fine. PCBs don't flake off stuff.

Conformal coating is good, to protect the board from the food! Cooking is nasty, with moisture, grease, flakes of dusty stuff, heat.

We were shopping for a new stove (aka cooker) for our cabin, and I was determined to get one without electronics. With electronics, they start at $500. Without, they start at $2000.

t $500.

The range touch panel electronics is no less reliable than the microwave to uch panel. The range should be on its own 40A breaker, just flip it OFF whe n you leave. GE and Whirlpool are mainstays, you should be able to get one for under $400, those models will have simplified bimetal-based heat contro ls for the stove top elements.

I work in power and consider anything above 60 Hz to be RF.

It gets exposed to a lot more heat and moisture. And I expect to throw away a microwave every few years, when the door breaks. It's a big deal to replace a stove.

Cook on an electric range? No way!

And will die in a few years.

Wound up with an NXR. Pretty good, Chinese stainless sheet metal and German gas burners.

A bit short, in aviation power is usually 400Hz.

I've never seen any kind of deterioration of the electronics control board of an electric stove. They're built for 15 year life expectancy.

Any differences in cooking are all in your mind.

What extravagance! The life expectancy of the peasant appliances is 15 year s, so you can get 75 years use out them for the price of that NXR. I notice they conveniently omit the weight of that NXR behemoth on the specificatio n sheet, no wonder changing it out is a big deal.

Anything under a MW is just noise.

Why do they charge me so much for noise?

Because you use too much noise. ;-)

That's a different department. Besides, it's really high quality noise.

No, it certainly isn't. The power has gone off at least five times in the last month (more likely a dozen).

That is the very low frequency part of the spectrum. Being high quality it covers a lot of bandwidth. Think of it as a delta sigma signal turning on and off randomly.

So out of 155 million cycles, you're missing a couple. That still sounds pretty good to me :-)

A *lot* more than a couple. If I were only missing a couple, the clocks wouldn't have to be reset. I wouldn't own a vehicle that had me walk home six times in a month. The only thing less reliable than the power is the satellite TV. Well, the Internet has been really flaky in the last couple of months, too.

I'm detecting a trend. The common element seems to be *you*.

I bet your post trimming button is out of order too.

No, the common element is that you're full of shit...

...as always.
