Do you have a neighbour who keeps pigs? Maybe you could make a deal.

What do you mean by double walled pipe? Big fat insulated or skinny stainless/black?

If it's a house/residence, get the thru-the-wall/ceiling kit from the same manufacturer. These are certified, but only as a complete system. If you improvise, insurance will laugh at you and deny coverage.

Or maybe that was Ace Ventura.

Nice! I've been contemplating calcium issues in my garden.

These appear to be of bovine origin, yes? Was this green bone or previously roasted?

It takes a great deal of courage to hang it out over the abyss. Believe me, I know. Cheers mate!

Nice! Well done, Stephen. It has a hint of early Bruce Cockburn, that hypnotic mantra he would build. I was waiting for the vocals to kick in.

Just off the top of my head, may I toss out some lyrics in that vein? I hear this as a close, female three-part harmony.

Walk these woods,
Walk these woods,
A circle,
Unbroken

Walk this world,
Walk this world,
Torn and hurt,
Seeking

Walk these hills,
Walk these hills,
Sunshine,
Rain down on me

Walk these woods,
Walk these woods,
A circle,
Unbroken,
Unbroken,
We are not broken,
We are not broken

I have seen a lot of sensors that plug into a Raspberry Pi. A friend of mine used one to monitor his greenhouse temps while he was at work. He did the programming himself, in Python (?), as I vaguely recall. I don't recall if he logged data on the Pi itself, but with the right programming I would guess there's no reason why it can't be done. I have no idea about cost, though.

I've been eating smoked oysters out of the tin for decades. It's never happened to me.

Maybe you cut off an oyster in traffic and it rallied its social media posse to get even with you?

... unless you have a poetic license in your wallet ...
