Here’s a wild idea. I’m an electronic engineer and it just came to me as an idea which I’d like your feedback on…

Is this worth pursuing?
Not to rain on your parade, here, but you asked for my feedback. The way I'm looking at this is that it's like the ordinary bucket level indicator, only prone to breakage, and it has a battery I'm supposed to maintain.
You could improve it by wiring it to the tractor 12V, in which case it's like an ordinary bucket level indicator, only prone to breakage, and it has a plug I'm supposed to remember to unplug when removing the loader.
One thing I like about my tractor is that so much of the design is mechanical, and made of parts I'm not likely to bend by accident. There are not many little bits hanging off of it here and there trying to get torn. Much of the "user interface" on my tractor is easy enough to understand, just by looking at it, that it is not immediately obvious that there is a user interface. The first time I ever noticed a bucket level indicator, it was a long rod passing through an eyebolt, the rod having a kink in it that rested right in the eyebolt when the bucket was level. I didn't have a loader yet, myself, and had never operated one. It took me a few seconds of looking at this parked tractor before it dawned on me what the indicator was, and why it might be necessary, it never having occurred to me before that the operator can't see the bucket edge. But it did dawn on me, pretty quickly, and it pleased me. I think there's a kind of tractor aesthetic that works exactly this way. It's a sort of mechanical resourcefulness. It's like you telling me a joke, and I get it, and we both laugh in pleasure because we share that clever instant.
There's a tendency in electronics to make things too feature rich and too breaky. The electronic world keeps reinventing itself too rapidly. In my work, I do a lot of computational fluid dynamics, and it's not unusual for me to run jobs on the high performance compute cluster that take, for example, 100 hours to solve on 40 processors in parallel. If computers got 1000 times faster, I'd still be running off for a bio break or to check whether the mail came, running that calculation in just 6 minutes. So, yeah, I'd love to see computer speed improve a whole lot. Let's reinvent that. Let's not reinvent these bucket level indicators that require no instruction to use, and no batteries, and at least on my machine are sturdy enough I don't think I could break it even if I worked it over with a claw hammer.
You know what was pretty neat? People figuring out that, using colons and parentheses and the 8 numeral and semicolons and so forth, they could type what you could interpret as little faces if you looked at them sideways. That's clever, pleasingly clever. You know what wasn't neat at all? Somebody deciding to scan text for these character strings and substitute little inline graphics. It replaced pleasant cleverness with hamhandedness.
Instead, why not go invent a nonvolatile timer that rezeros itself whenever the oil filter is spun off?
