On Youtube I watched a Mac user who had bought an iMac last year. It was maxed out with 40 GB of RAM costing him about $4000. He watched in disbelief how his hyper expensive iMac was being demolished by his new M1 Mac Mini, which he had paid a measly $700 for.
In real world test after test, the M1 Macs are not merely inching past top of the line Intel Macs, they are destroying them. In disbelief people have started asking how on earth this is possible?
If you are one of those people, you have come to the right place. Here I plan to break it down into digestible pieces exactly what it is that Apple has done with the M1.

Thanks. Quite interesting.
Inexpensive and simple microprocessors have made it possible to make some really unusual custom designs.
Talking about inductance, a radio amateur, Neil Hecht came up with a quite nifty scheme for a simple technique for measuring inductance.

Just for what it's worth. I found his research insightful. It's not particularly fast, but by taking advantage of how precise a microprocessor can measure time intervals, I was able to make some inexpensive yet accurate position sensors that are quite resistant to environmental factors.
I am trying to build stuff for the small farm. Arduino based so the farmer can maintain the thing without being held hostage to terms, conditions, licensing, monthly fees, and DRM enforced ignorance.

Whoops. No schematic.

Yeah, stuff like this: https://www.freightfarms.com/ [freightfarms.com] is very attractive, except for the lock-in style software subscriptions, etc. I think that the power of open source really needs to be applied to reproducible farming techniques like containers. $2 per quart locally sourced high sugar and flavor strawberries and similar goodies are very possible, if people can succeed in marketing them.

Here's another one

I intend to involve myself here when I get my act together.

Oh, Incidentally, the main reason for my Arduino bent is OPEN SOURCE. I hate "terms and conditions" to the end user with a purple plague.
This is all about sharing technology.
Take it, do what you will with it, and if you made it better, let the rest of us benefit too.

In my opinion, an open (source) container farming movement should hit critical mass much faster and bigger than any for-profit commercial operations are capable of, once the barriers to entry get low enough.
Container: $5K delivered
Insulation: $3K (spray on)
Interior framework: $1K - 2x4s should do most of the work quite well
Power: can be solar (up front investment with payback in a couple of years or less), grid or most likely hybrid.
Water: should be minimal / largely recycled as compared to open farming systems
LED lighting: figures I read ask for 40W/square foot, so a ~300 square foot container needs ~12KW of LEDs, which might run $1 to 2K
So, anybody with $15K, a very little land and the time to put in the work should be able to run a container farm, as opposed to $115K+ for the Freight Farm commercial solution. The real trick is getting effective information sharing going on among the builder/farmers. Once the open community gets 2-3x as many active contributors as a typical commercial operation has, I think you've got a sustainable revolution going on.

By the way, I respect the Arduino choice, but find myself firmly planted in the Raspberry Pi camp. When you can get a Pi Zero with WiFi & Bluetooth for $15, why mess around with anything less powerful?
