I wish we could disable “Validating OS”. When I pick up my calc, I just want to do the math. Not wait for a boot. Its why I still use my Ti-34 MultiView or Ti-86.

[@beartn]

It didn't always used to be this way, on calculators below rev C there was no OS validation, it just booted whatever was on it. Once they introduced rev C (boot code 5.1.5) they added this "feature".

dude i wish i was in the us so id be able to attend opensauce, so many awesome creators i love are going and to now hear the guy thats saved my exams many times is attending aswell makes me incredibly envious of the people attending. Hope you have lots of fun and make some content there :)

[@sonochan8679]

🤓Thanks to you, my TI-84 Plus CE has come back to life. Thank you so much!

[@alphaspace1100]

always a pleasure

[@TInyHackerCalcs]

Wish I could be at OpenSauce but it's too far away... will you be making any videos about your time?

[@TheLastMillennial]

Wish you could come! I expect there will be enough interesting stuff to make a video about!

My TI 84 Plus CE from 2015 is looking really nice right now

[@razer1158]

It’s like you can read my mind, my calculator has had this issue for ages now so I can’t even use it. After I gave up some months ago I’ve been waiting for something that could help me, thanks a lot for making thie

[@concordemachspeed24]

It seems like every time I see a TI-84 Plus CE, I feel there's something wrong or the calculator is yet again have a flaw.

[@thejummyjum6207]

he is back let's gooooo

[@paradoxicalegg6112]

Thank you!

[@beartn]

And this is why I'll never get a post rev A calc. Gotta love boot 5.0.0.0089.

[@rasbpilol7893]

Do you plan on going to any other OpenSauce events?

[@TheLastMillennial]

I definitely want to see some events if I have time!

[@Rdkey144]

Hi, I was looking for a calculator for engineering, and I don't know whether to choose the HP Prime G2 or the TI N-spire CX II Cas, which one do you recommend? thank you

[@TheLastMillennial]

I still love the HP Prime G2 and many of my engineering friends like it too. Just be aware that the HP Prime hasn't really gotten any software updates in a few years so any issues you encounter probably won't get fixed.

[@fernandoarduzruiz1541]

@@TheLastMillennial New 2.2.15008 beta update with a lot of bugfix

[@TheLastMillennial]

I saw, I'll be trying it out when I have time

[@ShinyTillDawn]

The other fatal flaw is that ZERO calculators are just better.

[@TheLastMillennial]

If you want to use one you'll have to come to OpenSauce ;)

[@PabloArduz]

My brand new Ti-84 plus CE model L, got this error, I tried charging externaly but when I tried again, the calc doesn't turn on, the battery doesn't charge anymore.....do you think that can I revive my battery???....

[@TheLastMillennial]

The battery sounds defective and I wouldn't try charging it anymore. If it refuses a charge then it's preventing itself from further damage. Contact TI Cares and they will send you a new battery for free.

[@PabloArduz]

@@TheLastMillennial Ti Cares just Cares US/Canada users, I am from LATAM, they send me to a local distributor to BUY a new battery

[@PabloArduz]

@@TheLastMillennial I found a Samsung battery comparible: EB494353VU from a Samsung Galaxy Mini GT......but the problem that you can't charge in the calculator

[@TheLastMillennial]

I see. Did you but the calculator directly from TI or a reseller? Whoever sold it should honor your warranty since the calculator became 'defective' on its own. I'm not sure if the battery you linked is compatible with the TI-84 Plus CE but if it fits and it has three contact pads then the calculator should be able to charge it.

[@PabloArduz]

@@TheLastMillennial yes it fits and contacts too, contacts fits the same dimen....battery level indicator works too with this battery....Maybe there is a chip in TI batteries that the calculator can detect to know if it is original or not.

[@guilherme11111]

Thank you!! My TI-84 Plus C Silver edition wasn’t charging. I pressed the reset button and now it is charging again 👏🏻👏🏻

[@twistedwhiskers8776]

Can you try to make your own graphing calculator with a raspberry pie zero

[@TheLastMillennial]

Writing a calculator from scratch is a whole different ball game than the projects I do. I've tried emulating calculators on the Pi Zero but it's far too slow for emulation. You'd be better off using Wolfram Alpha or an existing calculator application for it

[@twistedwhiskers8776]

@@TheLastMillennial I see. But if someone else were to do it it would be pretty cool and it could probably be done significantly cheaper than a TI 84

[@TheLastMillennial]

There's a startup called Zero that's basically making a TI-84 but using an Arm chip. I've made a video on the latest prototype.

[@twistedwhiskers8776]

@@TheLastMillennial yes I saw one other thing. Why don’t they put a micro SDHC card slot on these calculators you could store a TON of program

[@TheLastMillennial]

Increased cost, complexity, and lack of demand from schools. If Zero becomes more prominent in schools then they may start exploring options like that.
