r/calculators

Hello,

I have been using the Orion TI-84 Plus Talking Graphing Calculator. It is basically a TI-84 Plus with an extra unit on top that allows non visual navigation with a built in speaker / speech synthesizer. I love it because it has lets me do math.

On the Orbit Research website it says that you need a TI Connectivity USB Graph Link Cable to use TI ConnectTM Software for printing, embossing braille, and data transfer. I tried contacting Texas Instruments and they said that the cable is out of stock in the USA and Canada. Does anyone know where I could find a cable to purchase in Canada? I’m a bit confused on what sort of cable I need.

I've had the one without the sticker on the back for a couple of weeks now. It's a bit beat up, so I got that one for $40.

The second one on the bottom arrived today right before we got hit by a monsoon.

The driver set it on the hood of my car and it got soaked!. But thankfully the seller did an outstanding job of wrapping it (a bag within a bag, within a bag, so three waterproof barriers) and the calculator itself remained dry. It went for $75.

Maybe the only one to do an update to reddit, but got so many calculators since my last collection post that I had to make another one.

Right one is the new one left one is the old one. Idk if they changed the back and made like the professional one. Also new one is 1-2grams lighter than the old one. Have I been scammed? Also the packaging cover is also different from the old one. Am I tripping or this is how they make the new ones?

From top to bottom, left to right: HP Prime G1, TI–36X Pro, HP-35S, fx-115ES+, fx-991EX, HP-12C, DM–41X, HP-41CX (with PPC ROM, X Memory, Advantage module, & ZENROM), DM-16L, TI–84+ CE, DM–15L, HP-15C, TI-nspire CX II, HP-50G, fx-CP400, NumWorks, DM-41L, fx-CG50, HP Prime G2, HP-42S, HP–32SII, HP-48G+, DM–42, HP-49G+, TI-nspire CX, DM–42n, and TI–84 EVO.

Unit came apart easily. Danger zone was the keys are on a sticky rubber mat. With great skill (or dumb luck), I swapped the ln key and the sto-> key. Nobody will notice....

Every time I start scrolling down the entire screen either goes black or it starts to have making “bars” around the numbers

THIS IS A JOKE --- PLEASE DO NOT TAKE IT SERIOUSLY

The Premise

CalcByEA is a fully functional web calculator where almost every button is locked behind a paywall. You need to buy 'DLC packs' to unlock basic operations like addition, multiplication, and the equals sign.

The number 0 is free. Everything else costs money.

This is not a bug. This is the product.

It's satire on the video game industry's microtransaction model — specifically EA Games, who turned a $2 cosmetic DLC in 2006 (Horse Armor for Oblivion) into a multi-billion dollar monetization philosophy.

I built this as a mirror to the gaming industry. EA has been voted 'Worst Company in America' twice, and yet their model of shipping incomplete games and selling the rest as DLC became standard across the entire industry.

By 2021, FIFA Ultimate Team was generating $1.6B/year from digital card packs alone. The Sims 4 base game went free while the full content now costs $1,000+. Star Wars Battlefront II's loot boxes triggered government investigations into gambling laws.

So I asked: what if we applied the same logic to something universally free - a calculator?

Try it yourself. Try to add 1 + 1. See how far you get for free.
