Ti Voyage 200 Emulator Mac
SpiroH, thank you very much for response. I do not have any Nspire calculatror, but I have TI 92+. For Android phones, you simply install this amazing emulator from link. Of course you need a Texas Instruments TI Voyage 200 calculator [4]. For what we’re going to do here, the OS version doesn’t really matter, but just to let you know: I am using version 3.10. This is also the latest ever published version by Texas Instruments. 59 thoughts on “ Finally, an Upgrade for the TI-86 ”. Calculator app for Android that isn’t just a TI-86 emulator, by all means please share. Li-ion hack with my two TI-Voyage 200, I. Voyage 200 (also V200 and Voyage 200 PLT) was released in 2002, being the replacement for the TI-92 Plus, with its only hardware upgrade over that calculator being an increase in the amount of flash memory available (2.7 megabytes for the Voyage 200 vs. 702 kilobytes for the TI-92 Plus).
The eternal and everlasting TI-86 graphing calculator is a great calculator: first made back in 1997, and still used by students today. 
But its battery life kinda sucks. So [Dalius] decided to If you’re not familiar, the TI-86 runs off of 4 AAA batteries, preferably alkaline. 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. Luckily, this means if you get rid of the batteries, there is some decent real estate available inside the calculator.
[Dalius] 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. Isn’t technological progress wonderful?
Now you can recharge it just like your cellphone. For other fun calculator projects, check out Posted in, Tagged,, Post navigation. Who defines alkalines as empty at 1V? If they have significant capacity left, then somebody needs to redefine that. I can’t remember the graph of voltage vs lifetime that was posted here a while ago, but I think at 1V there’s really not much useful life left by then, they fall off pretty quickly once they hit a critical voltage. For this hack, it’s nice, makes it more convenient.

OTOH I might just have found somewhere to stick an extra NIMH cell in to bring the voltage up to 6V. I’m a lazy, lazy man. Seems like the “upgrade” is merely a charging upgrade, rather than battery life being extended. If the NiMH batteries were draining too fast, this will drain even faster, because just looking at the specs (3.6V 900mAh vs. 4.8V ~1000mAh for 4x NiMH AAAs), plus losses in the boost, this thing may not last nearly as long. 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).
If you have Express Scribe, then you don't need to do this. How to volume leveling of a song in Audacity| Singing software Bangla tutorial for singers For someone who wants to transcribe an audio file. If you find that the volume level in your audio is not uniform (some speakers speak too loud while others too low), you can use the Compression tool in Audacity. 
All you have to do is load the audio file in Express Scribe, go to Options, Other, Playback tab and set ''Volume autio-adjust, range compression' to Strong. This 'levels up' the audio file.

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. Are 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. There are tiny switcher modules on eBay nowadays — I picked up 10 for $5 not too long ago. Hmmm you could be right. I thought I’d seen 1000mAh Eneloops, but now when I went back to look, all I can find are 800mAh ones. Still, 4.8V @ 800mAh vs.
3.6V @ 900mAh, my money is still on the 4.8 @ 800 under similar conditions. I’d just like to point out that I made the same point when I said “However, just having the boost circuit in there might help it stay over 4.5V (or whatever its threshold turns out to be) longer” – I don’t deny that you might get more utility out of it, but at the expense of the life of the cell. Protection on the charge is one thing, protection from over-discharge is another.
I’m not really as concerned about the safety of this mod (it’s probably reasonable), but Li-ion cells don’t like to be fully discharged, and the boost circuit is probably going to work down to a voltage that is unsafe to keep the Li-ion cells at. Really, all I’m trying to say is, you want to make sure that the Li-ion cell stays charged — if it gets so discharged that the calculator stops working a handful of times, you’re probably going to have a dead cell and have to go in and replace it.
