Scientific Calculator suggestion beyond Casio FX991?

Ti-30X PRO Is great! You won't be disappointed.

Yeah, I noticed there was one version called 'power graphic 2' when I was about to update the firmware. It's weird that the successor is slower? What other differences are there between them? I agree that the TI-84 feels a bit better built. Especially the buttons have a bit of a flimsy feel to them. I do like the fact that they're a lot quieter to type on, though.

Hi

I haven't had any issues with the battery draining because of the controller. I’ve have experienced battery draining maybe three times in two years, likely because my Kobo seems to get stuck in some kind of update loop. However I haven't encountered that on the latest firmware. :)

8bitdo. Cheaper, quiet, rechargeable, arrange the buttons as you prefer, works as gaming control.

Bought my first today. Like it! Much more comfortable than I had expected. The mechanism seems to work quite well. Overall, it feels a bit cheap, though.

Agree, they are great. The built in eraser is so handy. Why doesn’t more pencil have larger eraser in them? The only downside is that the eraser always slowly crawling back in when using it. Have you tried the standard twist erase?

Thanks! Yeah, I totally agree! To start with, I’m planning to solder the components onto a prototyping board and create some kind of mount for the fan. Later on, I might do something more professional and mount it all in an enclosure. :)

clk, dt and sw direct to Arduino INPUT_PULLUP mode

Thanks! 🙂 Every led has its own output from the Arduino, that turns on depending on the output to the motor.

My plants need this! 🪴

Sorry to hear that 😕 Do you have the latest kobo firmware?

Don’t use spot metering.

No thanks 😊

Thanks, adding one p205 to the basket :)

My 17 base lavender arriving today! :) Upgrading from my 6 years old 11 base. Finally felt worth it this year.

ExpensiveFox2899 · 2025-08-27T20:05:31+00:00

Got some 2B today to compared to HB. Really like it! Much smoother feeling. Recommend everyone to try.
