Iphone 4S Internal Speaker? Answered

I just purchased an Iphone 4S from verizon 2 days ago, it is the white model. However, the Internal Speaker will not work, and has never worked for anything: Apps, Music, Videos, Ringtones, etc. I made sure the phone was not on silent mode and the volume was up high.  I thought that the headphone detection could be malfunctioning, however when in music, I set the volume to highest possible with no headphones and then plugged in my headphones and the volume bar went to the previous setting with headphones. This makes me assume that it knows to play out of the speakers. Help would be appreciated, if the solution is not fixed, I will be trading in the phone at verizon.

DIY Milled iPhone case? Answered

I am taking a class in automated manufacturing this year in school, and thus have to do a few projects requiring laser cutters/cnc mills. So I thought as kind of an extra project, it would be cool to make a case for my iphone 4. So the question: is it possible that I can mill myself an iphone case, probably out of wood (I prefer aluminum/stainless steel but that might just scratch the heck out of the phone), and if so, what type of wood should i use (I am clueless... not a carpenter :D ), any ways, any thoughts, or maybe someone has tried it before? Just though it would be a cool project if I could make it happen...

iPhone 4S popup too small to show close button and zoom deactivated, image upload broken on chrome, text editing broken on edge

Bug1: Instructables.com is not usable on an iPhone4s based on the nasty blocking nag-popup with hidden X/CLOSE. Replicate: - iPhone 4S with Safari iOS 9.2 (13C75) - Wait for the nagging "log in" popup - The close/x button is north of the screen, not visible, because the iPhone screen is not as big as your developers thought. - Zooming is disabled. Scrolling does not work as the nag-popup is using javascript to center. - There is no way to reach the X/close button - Nag-popup will not go away. - Instructables.com not usable on iPhone 4s. This is major PITA. Only way to get rid of nag-screen is ""reload"", but that was a lucky guess. Bug2: uploading Screenshots into this forum using Google Chrome DOES NOT WORK. Click "choose files" does not return anything. Bug3: although uploading screenshots works on EDGE Browser, clicking and entering the forum Text DOES NOT WORK. so- entering text into forum topic does not work on EDGE. so I upload pictures on Edge and enter this text in chrome... Do I reaaaaly need 3 browser to do this bug report? WTF? Only because I truly love instructables.com like a unicorn loves pink, I took the pain to write this report, despite this forum's "choose files" button not working when trying to uploaid screenshot. Damn, even reportig bugs doesnt work - get your s*** together!

Lipo battery cut off

I'm using a couple of Lipo batteries to power a speaker on a trailer, I bought 2 low voltage alarms that plug into the balance cables but upon testing I found it to be unlikely that I'll hear them over the speaker. So would it be possible to modify the alarms so that they activate some kind of cut off device attached to the power cable instead? Each battery is 4s 10000mah.

Laptop sees but won't connect to home wifi network, but can connect to other wifi networks?

My Vaio laptop with XP won't connect to the home WiFi network, which it used to no problem, although it connects fine to other WiFi networks outside the home. Same problem with the iPhone 4s - these were the only two wireless devices home when the problem started. The main PC hooked up to the router still has internet access, and other household laptops and mobile devices can still use the WiFi. I have tried resetting the router to no avail, as well as disconnecting from the network and reconnecting.

DIY Hot Tub Solar Heating

Hi. I have a solar tub heating system 3/4s complete. It's based on a 100W PV panel to drive a pump, charge the battery and supply the electronics. A 16.5 sq ft solar water collector to heat the water. The heart of the system is a (made in China) DST1020 water temperature controller. My first thoughts are to open the flow of hot water to the tub at around 25degC, and cut it of at around 34degC. Problem - this controller has a reputation as a great little device, but it's a b**ch to program, the various instructions online just don't work. All I want it to do is close the heating dry relay contact at 25C and open at 34C. Easy? No. Has anyone got experience of this controller?

Another Consequence of Rising Gas Prices

Everybody knows that rising gasoline and fuel prices are taking a toll on consumers' wallets. But few anticipated this problem: a shortage of numbers at gasoline stations. Since gas prices have easily surpassed $4 per gallon, gas stations in New York don't have enough 4s to advertise their prices--so they've had to improvise and make DIY numbers.Of course, with gas expected to hit $5 per gallon soon, some stations are prepared: On Monday, at a BP station on Coney Island Avenue and Lancaster Avenue in Gravesend, Brooklyn, a 2 had been turned upside down to make a 5 for the large sign on the corner.When the price hits the $5.20 range, though, they'll probably have to start improvising again.New York Times

Can I download photos off a functioning (not broken) phone after I stop using my current carrier?

I want to change mobile phone carriers, but am afraid that if I do I won't be able to retrieve my photos off my phone (iPhone 4S) once I'm no longer with the same carrier (I'll be using a different phone, as well).  See, the thing is, I want to switch my phone and carrier NOW, but I don't have the capability to download my photos off my phone onto a computer right now.  I will have the capability in a month or so - but, not now.  So, before I switch carriers, I'd like to rest assured knowing that I merely need to just turn on the phone and I'll be able to download the photos onto my computer. (easy, right? :D) Thanks for any help! :) Bunny

Series Parallel 4S2P Li-Ion Battery Pack

Hey guys,I'm busy making a boombox*, my first version had an old small car battery inside which obviously weighed a tonne!Looking to make the switch to Li-Ion.I have already purchased for the battery pack:8 x Samsung 30Q Li-Ion batteries (3000mAh - 3.7V)BMS board I found online (CF-4S30A-A)2 x 4S 18650 Battery Holders.I'm unsure how to go about setting up the batteries and balance cables etc. Need the 4S2P configuration for the Voltage.I want to expand this in the future by increasing to maybe 3P or 4P (depending on how much space I'll need in my boombox).I have watched multiple YouTube videos but sick of watching 15 minutes of somebody soldering. I understand the safety aspects of Li-Ion.*I know this project could have been done with Raspberry Pi or Arduino but the rest of the guys who will use this would not be familiar with hence why I went with a Car Stereo.If anybody has any criticism, I welcome it but make it constructive!(I know I'll get a roasting for the terrible MS Word wiring diagram I made)

18650 protection board limitations

Hi ThereI've been lucky enough to stumble across a large quantity of brand new 2600 - 3300mAh 18650 cells and I'm wanting to find some DYI projects to put them to good use. 200W flash light, electric Go Kart or a basic power wall comes to mind. However first things first Ill be needing to build them into a packs and connect them to protection modules but Ive got a few questions:Protection modules come in so many flavors. 2S - 3S - 4S - 5S - 5S5P and bigger.. Do you choose the module based on how many cells you have in total and then just use a DC-DC converter to get the required voltage? Or do you try to get as close as possible to the voltage needed in series first and then find a module that suits? What is the most versatile configuration?Can I connect 5S5P pack to a 5S module? Can I keep increasing in parallel with no consequences? Like for example can I connect a 5S15P pack to a 5S model and expect the module to be able to balance and charge the pack back up? I understand there are Amp draw limits to watch out for too. The module I was looking at is below.https://www.ebay.com/itm/191978019369Also this module requires a charge voltage of 21 volts at no more than 5Amps. Where would I be able to find a charger like that? A laptop power brick maybe?Any guidance would be great as I'm keen to learn as much as possible!Thanks in advanced!

Question by Plangy 

Looking for advice on LiFePO4 car battery replacement for SLA

I'm thinking of replacing my 12V lead acid car battery with a DIY lightweight battery based on LiFePO4 cells, but before I dive in I'd like to get some advice...My plan is to use 4 sets of 2 x ANR26650M1B cells in parallel, to give 13.2V output, and high output current, and about 20Ah capacity.(These cells seem to be used in commercial lightweight car batteries, so seem like a good choice.)Now, question 1: Can I just use these 8 cells as a drop-in replacement? With, presumably, occasional balancing out of the car.I think the answer is no: while my initial research suggests that some people are using off-the-shelf LiFePO4 cells in this way, a whole lot more people write about the protection and balance electronics they're using, and I don't suppose they're all wasting their time.Question 2: If Q1 = "No", would adding a balancing and protection module enable the cells to work safely in the car? There are 100A and 200A 4s modules available, so they should be OK with starting current (c. 120A in my case). I guess it's a question of whether it's OK to have such a protected battery pack constantly hooked up to c. +14.4V from the alternator, or whether I need to limit the time that the battery is charged from the alternator.Question 3: is it smarter to use super capacitors plus lifepo4 cells, to enable higher starting current while keeping battery discharging current low? (I started out thinking of combining an RC LiFePO4 battery pack with 6x400F super capacitors, but realised that I could get enough current with the ANR26650M1B cells, and fewer components should mean less to go wrong)

Big battery bank project. Circuit related questions?

Hello everyone! I have a project in my mind and I would love some guidance and some ideas if possible. I already have a lot of 18650 batteries in an “acceptable” state (1800-2100mAh each) and I am planning to make a large battery bank, for use in camping mostly (smartphone charging, led bulbs, electrical air pumps 12v, etc) I did read a lot of articles in here about battery banks, but i didn't find something as complex as my idea. I have already made a 12v battery pack with 12x18650, 3 rows in parallel, of 4 in series in each row. My goal was to operate a 12v air pump for inflatable mattresses. It worked like a charm! (Also created with instructions from here! Thanks for that!) But since my “DIY disease” does not leave me in piece… I want to build a large enough pack that can support the following: 1) 12v car plug 2) 5v/1A + 5v/2.1A USB plugs 3) charge circuit for the battery pack, so I will no longer have to remove the batteries to charge them separately 4) switches in each plug 5) led voltmeter also with switch ?) at some point I would like to add a circuit to charge it with a solar charger or a mini wind turbine that i will create at some point with my 3D printer, but for now let stay with the basic stuff! For the case i will use a modified screw organizer case, with those classic 18650 black holders from ebay. (photo below) The case will fit almost 8 to 10 holders (4x18650), so we are talking for 32 to 40 batteries... My main concern is the circuit design. I have done a few simple things in the past, but this is a bit more complicated and that is why I want your guidance/ideas. How to safely connect all those things together or maybe suggest a different plan/design, cable thickness, etc... Links gathered so far: I am thinking about 4S in a row. Is that too much? Or should i consider 3S? 3S Li-ion Charger PCB with BMS For charger... something like this maybe? 12.6V 5A Charger optional... maybe i could fit sothing like that, for laptop charging? 150W DC-DC Boost Converter for 5v 1/2.1Amp charger i m looking at this. 5A Charger Step down Module for usb/12v plugs/voltmeter i am considering this option. Thanks in advance for your time!

How to charge a Powerpack of 18650 li-ion cells 4s3p 14.8V?

I plan to make a portable audio system with 4 speakers and a subwoofer which are driven by a 12v TDA2030A 2.1 Amplifier. Everything is already packed in a small enclosure (approx. 30x15x30cm) and works fine so far. At the moment the amp gets it's signal from a 3.5mm audio jack and the power is provided via a 12v 1.5Ah wall wart. That's what I have for now. But that's not really portable right? So to complete my project I want to add 2 more things - a bluetooth receiver powered with 5v and of course I need to get this thing of the mains. That's where my questions actually starts. I've read tons of forum posts, instructions and watched a lot of videos about making a 12v battery pack but I'm confused with all that information. From what I've read 18650 Lithium-Ion batteries have an excellent power density and would suit my system best (small enclosure and portable). But of course I'm open for new ideas anytime. I planed to make the power pack out of 4s3p 18650's from an old laptop battery (don't have the exact data of them yet). So the pack would provide about 8Ah at 14.8V nominal. With a step down converter to 12v it't could power the amp and for the bluetooth I would use a car usb adapter to get the 5v needed. So far so good, but regarding the power pack I have a few questions. 1. Would a 3s4p (11.1V) arrangement be good enough to power the 12v amp since the 11.1V are in average right? 2. The biggest question I have is - How to charge that thing? As I want to have it as portable as possible, to be able to charge it anywhere from a normal power socket would be ideal. I know there are dedicated chargers for lithium batteries but they are quite expansive and not really handy to carry around. Is there any other solution to handle that? 3. BMS, PCB - I'm confused. From what I've read, to charge multiple cells they have to be in balance right? An over-charging and over-discharging can lead to fire/explosions and to prevent that a BMS is essential right? But first - how do i connect that BMS? Only to each of the parallel strings or to every single cell? Second, is it possible to use that BMS to charge the pack? Maybe also in balance? 4. For the case that the 18650 from the laptop battery are undercharged, where is limit to withdraw them and to charge them to balance with a TP4065 at 1A? That's it for now. Sorry for the long text and thank you for reading through it. I read so much on the net but didn't find the right answer for me.
