Yes it might not appear to align right, but that's only because the ruler is slightly above the calculator.

My calculator is exactly 178mm long, which is the definition of the length of one banana...

It's probably laced with brain worms..

Nah, it's not Kool-Aid, it's orange juice.

Apparently OJ is going for like $11 a gallon in some places.

That's a disturbing thought, but given the state of the current shitshow, that sadly sounds about right.

Don't give them any ideas though..

Um, I hit a deer on the way here, sorry to say your food spilled all over the car. But I have some fresh deer meat in the trunk if you'll help me skin it and dispose of the carcass...

What they really ought to do is increase the legal minimum wage to match up with the rate of inflation. But no, there was no mention of that whatsoever...

Did you know that when you buy a pack of hot dogs from the store, they're actually cold?

And fresh eggs? Don't get me started on that, those eggs came out of the chicken's ass like 3 days to a week ago!

They've been lying to us for ages!

Did you know? (lemmy.world)
 

Also, apparently baby oil is made with synthetic babies. I'm so disappointed, how do people live with all these lies? ☹️

Update: To answer your question, yes apparently the calculator is indeed sensitive to variables such as battery voltage and even possibly/likely the temperature.

I made a couple tweaks to the display layout, but left the core minute pixel timer algorithm alone. Tonight's test shows it's already off by a minute after only 25 minutes of running.

Oh well, it's still a fun experiment, even though I was already aware I might be playing with digital fire with this silly project. 🤷‍♂️

It doesn't even need batteries, it can run directly from USB power with no batteries, but that doesn't answer any questions of how or if voltage levels affect instruction or pixel timing.

Welp, one of my 4 batteries died today (no worries on the memory on this model). I found a spare battery, but between that and switching back and forth to USB power, it does seem the calculator's speed might be lightly affected by voltage levels and even possibly by temperature.

Hey, ain't nothing perfect...

Hey, last I checked, Tonka Trucks don't use fuel...

WINNING!!!

Very good question!

At this moment I don't know for sure.

I've only been running it on consistent 5V USB power until yesterday.

I am keeping the voltage level question in mind though...

 

I added a few effects and stuff to my previous calculator demo, along with a signature line.

The weird symbol in the middle of the screen towards the end of the demo is literally Casio's text mode entry flashing cursor.

Shame on Casio, they knew...

I couldn't find the exact pixel dimensions for this calculator, so I just measured it myself.

1 Centimeter = 22 Pixels, exactly.

Edit: It might not appear in the photo to be an exact alignment with centimeters, but that's all because of the ruler sitting a little higher than the screen and the camera optical focus and crap.

Indeed, it's exactly 22px/cm

 

Hey, if they really quit making them, collect!!!

No manual, just past experience with other graphing calculators and experimental programming.

Enjoy...

 

Yes, 355÷113 is very close to π, but is not equal to π

So how does it get things 'right' for cos(355÷113), but not right for sin(355÷113)?

And why is the error of π-355÷113 exactly the same as the error of sin(355÷113)?

I sense some fuckiness of how they handle π...

 

The calculator as a whole seems to work perfectly, but can anyone explain Casio's choice of the shape of their flashing text entry cursor?

Found this trash in the wild today.

 

Why are their images always blurry? My phone is sharp as a tack!
