And if it’s a real emulator, meaning they somehow got hold of the ROM code and the CPU and hardware are well enough documented, then running the ROM code means they don’t have to write the mathematical software themselves, or the graphing methods, and all that other arse-bind.Įmulators are well-established, lots of people have written them. If that’s what does it best… They put a lot of effort into designing calculators after all. Changing status quo is not even to be thought about. Stuff like student councils cause more harm than good, giving kids power over the equivalent of arranging deck chairs on the Titanic, teaching them that politics is all about petty bureaucracy, and all the real power is out of your hands, in some shady room somewhere. I remember school, I was a smart kid, I can promise you this. There’s stories of kids caught using a command line on school computers, getting in trouble for “hacking”. Arbitrary decisions, nobody’s really accountable, means stuff like urban legends end up implemented as policy, along with completely arbitrary other rules based on teachers’ innate prejudices or mental instability. Then again again school power heirarchies are insane anyway. Then again calcs like that are often not allowed in exams anyway. There are tiny switcher modules on eBay nowadays - I picked up 10 for $5 not too long ago.Įxpulsion if used like that during exams, right? Students chat all the time during normal class, long as it’s not affecting anything crucial. In short, given that this is using cheap eBay parts, and is likely to not have the proper shutdown voltage to keep the Li-ion cell safe, I expect it might turn into a short-term victory involving having to replace the Li-ion cell more often than one would like.Īre there any linear regulators dropping the voltages inside down to 3.3V or other voltages? Seems like one thing to try might be swapping that for a switcher if you can find somewhere to fit it. However, just having the boost circuit in there might help it stay over 4.5V (or whatever its threshold turns out to be) longer… but you also run the risk of over-discharging the Li-ion cell with no way to really tell if it’s facing certain doom (hopefully the step-up module shuts down at a good input voltage).

4.8V ~1000mAh for 4x NiMH AAAs), plus losses in the boost, this thing may not last nearly as long. If the NiMH batteries were draining too fast, this will drain even faster, because just looking at the specs (3.6V 900mAh vs. Seems like the “upgrade” is merely a charging upgrade, rather than battery life being extended.

Now you can recharge it just like your cellphone.įor other fun calculator projects, check out our recent Hacklet dedicated to all things calculator! was able to fit a 3.6V 900mAh lithium ion battery, a step-up module, and a USB Li-ion charger all into the compartment, complete with a micro USB port sticking out the side. Luckily, this means if you get rid of the batteries, there is some decent real estate available inside the calculator. If you use rechargeable NiMH they don’t last very long since they have a lower voltage per cell, which means it ends up draining even faster to a voltage level the TI-86 cannot operate at. If you’re not familiar, the TI-86 runs off of 4 AAA batteries, preferably alkaline. So decided to bring his TI-86 into the 21st century. All rights reserved.The eternal and everlasting TI-86 graphing calculator is a great calculator: first made back in 1997, and still used by students today.
