Re: [Audiogames-reflector] low batteries in electronics
Re: low batteries in electronics I was going to say something else that happened to me, something quite funny, but I cant remember what it was. Oh, I heard that if you drop a battery on the ground, there were two ways you could tell if the battery was good or bad. If it didnt bounce, its good. If it bounces, its bad. I have connected two nine-volt batteries together. I tried doing some electrolysis to see if I could separate water and salt into different chambers, but you would need expensive equipment.Now I am getting off-topic. Anyhow, I am thinking about those times I had a Walkman. The batteries would be new and sure enough, the tape sounded very high, not in a gross way but more in a subtle maner, and could be hard to tell if you didnt pay attention.URL: http://forum.audiogames.net/viewtopic.php?pid=167779#p167779 ___ Audiogames-reflector mailing list Audiogames-reflector@sabahattin-gucukoglu.com http://sabahattin-gucukoglu.com/cgi-bin/mailman/listinfo/audiogames-reflector
Re: [Audiogames-reflector] low batteries in electronics
Re: low batteries in electronics I remember when I was little, when I was playing the original bop it toy fro Hasbro, that if you had a low battery, the toy would emit weird squeaky-like sounds. This sound always made me laugh because it sounded very funny.What other unusual behaviours that you found entertaining than toys going towards self-destruction?URL: http://forum.audiogames.net/viewtopic.php?pid=167586#p167586 ___ Audiogames-reflector mailing list Audiogames-reflector@sabahattin-gucukoglu.com http://sabahattin-gucukoglu.com/cgi-bin/mailman/listinfo/audiogames-reflector
Re: [Audiogames-reflector] low batteries in electronics
Re: low batteries in electronics I had a toy talking repeat what I say type toy. eventually, as the battery life went down, the pitch would randomly change until it squeaked and totally started making clicking and stutering noises and even then it still... somehow... ran, then all the sudden about 5 minutes later it gets to where its pitch is high enough that it emits a frequency that basically is so high my furby 2012 responded, thinking I was trying to use the furby IOS app!URL: http://forum.audiogames.net/viewtopic.php?pid=167608#p167608 ___ Audiogames-reflector mailing list Audiogames-reflector@sabahattin-gucukoglu.com http://sabahattin-gucukoglu.com/cgi-bin/mailman/listinfo/audiogames-reflector
Re: [Audiogames-reflector] low batteries in electronics
Re: low batteries in electronics Hi.I can add the following:when using normal batteries, not the lithium batteries, the batteries gives out random voltage when they are about to die. The reason for you have to put more than one battery in toys, for example, is because one or two batteries controls, for example a motor, and the other batteries controls the sound, lights and other functions.Then, when batteries who are about to die randomly spits out different voltages, amount of power, the toys starts to react randomly and starts to sound weird, because they are getting the wrong amount of power.As a kid I had multiple cool toys like walking dinosaurs and simullar things. I also played around with dieing batteries, and tried once something really funny:I put three dieing batteries in an old walking dinosaur and turned it on. Normaly it should walk very slowly, but suddenly, it starts to run 50 times faster than normal across the floor, bumped into a closed door nearby some stairs, fli pped around in the air, landed on its legs and ran down the stairs! The poor dinosaur got damaged a lot, but thankfully, my dad could fix most of it. A friend of mine tried the same with a car. Sadly, it got so much power that it drove into the wall, and splintered over his room. The car took so much damage that it was impossible to fix again.I have always wandered how dieing batteries could suddenly go crazy and react like this. It doesnt happen very often, but when it happens, its not always that fun.

Re: [Audiogames-reflector] low batteries in electronics
Re: low batteries in electronics Li-ion batteries do not discharge completely because a total discharge strains the battery, and it could charge with a much lower capacity than it had previously. My question was, after the voltage limit for a device thats aware of its battery has been reached, could that device theoretically continue to function behaving erratically, or is the device designed to continue operating until it absolutely cannot. As an example, I believe the braillenote mpower has a ni-mh battery, and the classic may have a ni-cad, though Im not sure. When they reach their critical mark, soon after theyll turn off, but in the case of the classic, a press on the reset button elicits a beep but nothing else, and a service reset on the mpower causes the braille display to cycle. Im just wondering if they physically do not have enough power to start, or if there is an instruction not to boot below a certain voltage level to avoid corruption. Im guessing the sped-up moto r was caused by an incorrectly executed instruction; there may have been plenty of current for the motor but not enough power for the more sensitive microprocessor, or a voltage fluctuation. Im wondering what happens to a simple microprocessor like that when it does not have enough power, why it reads incorrectly instead of just ceasing to function, and if there would be any way to predict what it will do.URL: http://forum.audiogames.net/viewtopic.php?pid=167253#p167253 ___ Audiogames-reflector mailing list Audiogames-reflector@sabahattin-gucukoglu.com http://sabahattin-gucukoglu.com/cgi-bin/mailman/listinfo/audiogames-reflector
Re: [Audiogames-reflector] low batteries in electronics
Re: low batteries in electronics Interesting topic. Most laptops Ive noticed auto shutdown at around %3, and then even if you force them to keep going theyll literally cut out, though as has been said I dont think the battery is %100 dead at this point. one interesting fact however is one Acer I used to own actually used to overheat as the battery got low. Youd get the dreaded blue screen of death, the fan would start up, and the only way to solve things was to physically shut the thing off and wait for it to cool down, (one reason I have never trusted Acer as a make though odds are theyve fixed this issue). In terms of weerd battery behaviour, my old parrot voice voicemate was one of the weerdest. itd start giving audio low battery warnings, but then at some point itd literally start stuttering and putting out a load of static, rather lik the sound of a badly tuned radio or one of those old dialup modems. I 39;m fairly sure this was the random vaultage thing previously mentioned, but it really spooked me when I first heard it.One thing I do find interesting is that laptops and phone batteries seem very different in care. With my laptop, I kept the batteries bgood by running them down as much as possible, and never letting them just trickle charge. Indeed, often (as in fact Im doing now), Id utterly remove the battery from the machine once it was charge if I wanted to use the laptop on power. With my Iphone however, I have read articles that claime the more you run the battery down, the less over all life it will have, therefore its best to keep it on power as much as possible and only run it down to zero once every couple of weeks. This is what Ive done, I have my phone plugged in most of the time while Im at home, and plug it back in if Ive used it partly, however once every couple of weeks Ill deli berately run the battery to zero. As I got my Iphone in october of 2012, and the battery still seems to last just as long as when I got it, i can only assume that Im doing something right.URL: http://forum.audiogames.net/viewtopic.php?pid=167257#p167257 ___ Audiogames-reflector mailing list Audiogames-reflector@sabahattin-gucukoglu.com http://sabahattin-gucukoglu.com/cgi-bin/mailman/listinfo/audiogames-reflector
Re: [Audiogames-reflector] low batteries in electronics
Re: low batteries in electronics hi dark, lithium batteries have a limmited number of recharge cycles, this meens they can only be charged a certin number of times. before there ability to keep there charge for as long as u are used to. begins to fade. and there life becomes shorter. as for laptops. they do indeed can be set to continue on beyond the 0 percent mark. but as i stated. this wil in the long run damage a lithium battery. in the sence that. it is never good for it to be run down so completely. not because it wil build up a memory, since they do not suffer from that affect. but because battery ware will acurre the acer probably behaved that way. because, of bios issues. bare in mind. there is code in the firmware of the laptop. to work with the battery. and if this code is not well written, it might behave in the manner you described, now, wonderer, your answer to your question is, yes, they can opperate, but they have code in place that checks battery conditions, and thus shuts itself off. so let us say u have a battery, that is, for some reason faulty, let us say it gives out its state as low. and misleadingly says it has 0 percent left. guess what. the code built in to the device would stil shutt off primiturely as it reds this info from the battery. so. if, some how you could moddifie the code not to shut off, or some how could mess with the batteries reported out put you might in theory perhaps be able to continue device opperation. but as u said your self. that behaviour will certenly leed to device damage. not even to mension battery damage. [ a-t ] dark? if u have a laptop made in the last few years chances are good it uses a lithium iron battery. u are dooing things right by actually. remooving. the battery when not in use. its a widely debated topic as to weather to leave it in the laptop or not. but its true that what u are doing is actually the right thing. because u are actually preventing the battery from using up its charging cycles primaturely, . here is a example. let us say the batttery is in the machine. let us further more say the battery trickles down from full charge to say 97 percent. guess what happens? the charger starts to charge the battery. and guess what? boom goes 1 charging cycle. well wasted. so what u dooing is really to only use it when it is really needed. niccle iron batterys how ever must never be used this way. but run down completely and then be charged fully since they suffer from the memory afect. how ever since your laptop is programmed to shut down at 3 percent. and even if u run it all the way down. that is stil fine. even though u probably have a lithium iron in there. but never place it on 0 percent. and then. let it run down completely. u do risk ware, evensually.URL: http://forum.audiogames.net/viewtopic.php?pid=167274#p167274 ___ Audiogames-reflector mailing list Audiogames-reflector@sabahattin-gucukoglu.com http://sabahattin-gucukoglu.com/cgi-bin/mailman/listinfo/audiogames-reflector
[Audiogames-reflector] low batteries in electronics
low batteries in electronics So this is something Ive been curious about for a while, Im not really expecting anyone here has a definitive answer even if there is one, but ah well. When certain electronics are low on batteries, as an example those alphabet and piano toys kids play with, they usually start behaving very erratically, as in not just a distorted voice, but random looping, scrambled speech, incorrect responses etc. I remember as a small child when I got bored I would intentionally try to find dying batteries to use in the toys I had for the completely unpredictable behavior Id get in some of them. So, does anyone know why this happens? Obviously with simpler things (Im guessing things that did not turn on and off and so did not have a real-time OS) all that would happen is the sound would get lower and slower as the voltage decreased, but the more complex ones would just start behaving erratically and sometimes the voice would not change. Perhaps the CPU fails to read or ex ecute data correctly below a certain voltage, or maybe what RAM there is only holds partial data, and when attempting to read it appears as if a null pointer is referenced, and I doubt the firmware in those things has any error-handling code at all, so it just tries to continue despite the errors. Computers, phones and most other devices that actually serve a useful purpose usually warn about a low battery, and continue normally until it dies, (a certain voltage is reached) at which point they just turn off. If they were to try and continue functioning below this voltage, would they start exhibiting erratic behavior as well, or are they designed to make the most of the battery, behaving normally, and when they stop functioning its because they dont have power to stay on? In a simple childrens toy theres not too high a need for a low-battery warning, but that kind of erratic behavior in a laptop or phone could cause a whole lot of data corruption. If anyone kn ows more about this your thoughts would be appreciated.URL: http://forum.audiogames.net/viewtopic.php?pid=167192#p167192 ___ Audiogames-reflector mailing list Audiogames-reflector@sabahattin-gucukoglu.com http://sabahattin-gucukoglu.com/cgi-bin/mailman/listinfo/audiogames-reflector
Re: [Audiogames-reflector] low batteries in electronics
Re: low batteries in electronics hi, let me answer your questions about sell phones first. the reason why they can continue in a orderly manner. and not fluff up completely is the following. first? there is a battery meter inside the phone. its a sirkit that measure the battery level. it talks to the battery as it were. so to over simplified it, it goes like this. so it says. hay u, lithium iron battery? that is the battery used in most. sell phones. of today.battery, yes sir! phone? whats your status. battery talks back. 10 percent. phone says. oops ok. we display to the user. 1. bar remaining. some will give percentage some? will give u bars. now. the software on the phone is programmed to start playing the battery low sound. but? another thing happens. remember on phones. not much righting operations is done. this is why not to much data corruption will acurre.but there is 1 other thing that happens. the phone. continues. to o perate normally for the power is constant in the battery. meaning a constant power flow is supplied. when the phone asks the battery hay. how u keeping there. and battery says! 0 percent! the phone says. woof! by by off i go. and it shuts itself down.but now we go to the deeper explanation.lithium iron batteries has a chip inside it that actually never, never lets the lithium iron go empty. it never discharges itself completely. yes i no, the phone lied to you when it said the battery was empty. but the battery is to blame, and here is why.the battery will, once its power is depleted. shut it self off. and prevent itself from being used further. that might even be a phone safe or battery safe feature. or both. but in actual fact there is still some juice left. this juice is left to secure a soft flowing trickle of power inside that battery. witch is why u must never leave it empty for long periods of time. and here is why. and by the way. this includes laptops as well. If you do leave it. the chip inside that battery will eventually run out of power. and trigger a sleep state with in that battery. that sleep state disables the ability for that battery to be re charged and thus it will appear dead. only booster chargers can revive them. but your average Joe does not have one. and a good thing that is to. the reason for that is that sell corrosion acurres. so its a fail safe device built in.i no i deviated allot from what u asked, but i had to work my way around the water boll. to explain a few things to you. now, my guess, in toys. is that is using some sort of nickel iron battery or some sort. witch does not require the complexity of lithium batteries. so the power control in the battery can fluctuate. a good example of this is a walk man. remember those ones in the olden days that used to play tapes? the less powerful the battery was. the slower the motor would turn. the more slo wer the voice went. why? simple. the battery cannot supply the voltage needed. so it gave what it could? and then from there. things when down hill.remember, they used 2 batteries of 1.5 volts. for a total of 3 volts. but if the voltage of each battery dips below say. 1.25, the battery stops. because? not even enough power is in it. to turn the motor. the more voltage. it gave? the faster the motor could turn. that was why your tapes always seemed to play at a slightly higher pitch when batteries was new. and they was freshly taken out of there packet. but as time when by, they evened out?and the tunes then, became slower and slower. my theory of that example spills over in to toys. there is no voice to slow down since it might be prerecorded. or it might be digitally recorded. so due to incorrect voltage, the little system could not supply the necessary sirkits power to open and close the necessary relays to trigger the correct response. remembe r, some toys have little rubber contacts underneath them that conduct a small charge and thus begins the process of the action u started. i hope this all made sense. he smiles. feel free to ask if u wish to no more.URL: http://forum.audiogames.net/viewtopic.php?pid=167202#p167202 ___ Audiogames-reflector mailing list Audiogames-reflector@sabahattin-gucukoglu.com http://sabahattin-gucukoglu.com/cgi-bin/mailman/listinfo/audiogames-reflector
