You can get a usb based, digital glucose meter from Bayer called the Contour USB. It even has a display built in.

It's potentially free after coupons if you are buying strips.

But the glucose meter market is a huge scam, with what is essentially 1 cent litmus strips being sold for $1 each - manufacturers are milking insurance for all it's worth and the people without insurance have to spend a small fortune.

I'm sure it's extracting many millions from the economy that could be far better used.

Now that's a racket I'd like to see a startup disrupt someday.

The test strips for my former meter are $64 for 50. Sometimes I just don't test; I can get away with that because I don't use insulin.

Kroger (King Soopers in Colorado) has partnered with Wave Sense to sell a cheap meter (most meters are cheap anyway); the test strips are $34 for 100. I test a little more now.

Not a startup type disruption. The pharmacist told me Kroger just wanted to help out.

I'm imagining a $100 device that instead of using any supplies like strips or needles, maybe uses a ultrasonic pulse as a micro-drill to extract a molecular sized droplet of blood to test.

Then it would clean itself using the same ultrasonic pulse emitter.

Or maybe forgo the whole blood deal and somehow use saliva.

It should be possible with saliva but the conditions are finicky. You have to make sure you're reasonably hydrated, but haven't eaten or drank anything in the last 10 minutes, etc.

Not that I disagree with most of what you said but my mother is diabetic, recently diagnosed, and from what I can tell the strips have some sort of micro-channels.

You touch blood to one side or the other of a test strip, none of the blood is visible other than where it's touching the test strip. It gets to the meter internally through the strip almost instantly I'd say in less than half a second if not less, pretty much instantaneous.

Too bad there isn't an open source meter and cheaper strips.

By the way on Reddit there is r/diabetes if anyone wants to join whether you're diabetic or not.
