Hi everyone I'm trying to test a locally hosted website on my phone, but it won't load. I typed "ipconfig" into my cmd to get the IP address and then entered [IP_Address]:[PORT] into the browser. I've tried this a few times and all it says is "[IP_Address] took too long to respond". I've...

I am seeing lots of brands of home portable air conditioners to cool rooms. They are sold through well known nationwide chains such as Currys, Argos in the UK. Customer feedback shows that they really work. But why would they work??? Surely, these portable aircons need to take away heat from...

Hi there! I am a student in my first semester of undergrad studies for computer science. The first assignment in my CSC class is to write a paper on the future of computer science, which can be broad or niche. My end goal is to get a job in mobile computing forensics analysis, so this is what I...

I know in RVB theory that neighbouring Copper atoms form singlet pairs via the superexchange "force". Upon doping with holes, these neutral singlet RVB pairs become mobile and charged and are able to superconduct. I know that the resonating valence bonds are in the copper 3d(x^2-y^2) orbital and...

I'm thinking of: a.) downgrading/sizing to a pre-paid/pay-as-you-go cell phone plan, instead of a fixed monthly one b.) getting rid of data plan You can buy prepaid plans for literally whatever (I think the minimum is like $3.00) amount you want and use minutes and/or data as you go. The...

Could this be a good essay for school or college children to write a essay on "Life without Mobile phones today" as the essay title? The Mobile phones (Wireless technology) has impacted our lives and its hard for us where once upon a time we were using land line phones (wired technology) and...

Hi, I was looking at some notes and trying to understand the following statement which refers to the diagram below. "The number of cells in the radius ## D ## determined by ## N_c = D_R^2 ## where ## D_R = \sqrt{i^2 + j^2 + ij} ## where ## i## and ##j## are the number of cells along the ## u ##...

I have a question if it would be possible to have a cellular network on Long-Fi? I have tried searching for information on the theoretical maximum bandwidth of Long-Fi; but, can't find anything. I also am unsure if the idea would be of interest to companies like Tesla to set up a hub connecting...

This new technology will make monitoring outside of labs possible. It requires a brain implant. Kind of reminds me of the Borg.

Why SAR value at body is allways higher than at head?

I am currently working on a project for an undergraduate course in university. My team and I have decided to make a hydropowered mobile device charger, and I am responsible for the design and modeling of the turbine propeller. This turbine will need to be able to function in low velocity streams...

Somebody on the Slack for one of my online classes shared this interesting mobile website where you can draw a mathematical symbol and get the LaTeX equivalent. http://detexify.kirelabs.org/classify.html

Hello! I'm in the early process of brainstorming plans for a roof mounted mobile solar array as a DIY project. The host vehicle will be a 8.5'x20' cargo trailer. On the roof I can fit an array of 6x solar panels that is almost exactly 8.5x20. However, I actually want to create 3 such arrays...

Please help me. How many times I can charge my 5000mah mobile from 12 volt 7ah battery. I will use dc mobile charger.

Enjoy my collection of physics&related html mini applications, it's free and not commercial (I did them for fun and for my kids at extra school lesson). The idea was "so you have this adress and discover by yourself what is that". Some are simply just external links to PHeT etc, some are unique...

Hi all, want to realize a system for a PCB which holds a solenoid coil moving in a vertical axis long about 600 mm. The coil must get electric contact only in some predefined positions so that, for a given quote, the coil connects to a different LC circuit for having different resonant frequency...

I think max. voltage of a mobile battery is 4.3 V and voltage of a USB charger is 5 V; My question is , if we keep the charging process on even after mobile battery is 100 % charged, is it true that it will damage the battery ? Does it reduce the life of a battery or does it reduce the charge...

This is really cool using PVC pipes and 6 motors. Imagine how you could extend it with various sensors and making it autonomous:

It's easy to get information about the channels that the various 2G, 3G, 4G services use but I want to find out the actual frequency my service uses in my home. I was hoping to try a 'passive relay' arrangement to bring the (totally rubbish) signal from upstairs to downstairs by my computer. I...

Does a current (or a mobile charge) exert any force on the stationary charge (charge with no motion)? We know that the current produces a magnetic field around which exert a magnetic force on mobile charge and now I like to know whether the current exert force on a stationary charge.

I currently use my phone's data plan (T-Mobile) for doing some work on the road, but I have some larger projects coming up that could really benefit from being able to use a laptop. I still can't get used to texting/typing on the ultra small keyboard of a tiny cell phone and hate doing it...

Behold my first photos of stars...:smile: Thanks to PF members and PF threads, and reading about astrophotography, I succeeded the first time. This was just some tests I did with my mobile phone, LG G4, which has a pretty decent camera which can be used in manual mode, i.e. I can set the ISO...

I have a typical problem. I have two bars mobile signal in my attic - none at ground floor level. The reason is a roadside pole transmitter less than 500m away installed down in a dip behind houses (duh!) An electrically powered signal booster is illegal in the UK which atracts a £5000 fine...

I know quite a bit about tracking cell phones that are network contract phones. I need to know if it is possible to track a prepaid cell phone. I have heard that there are apps you can down load to a prepaid and there is a pay site that can then track the app on the phone. Has anyone had any...

The Rating on my Mobile Phone Charger is: Input : 100 - 240 VAC 50-60 Hz 0.15A Output : 5.0V ⎓ 1.0A How will we determine the energy consumed by the charger in T Hrs?

Hi, Where can I find a research or statics about the contribution of cellulars or general mobile devices (tablets, PDAs) to the global warming? But I am looking for specifically cellular phones for a project. Thanks a lot!

When should someone create an application for a mobile or a website, if you were to create one of the two? If you have an idea that can be created to be hosted on both, then which would you choose?

So I just got out of college and have about 15k or so saved up. My job pays me about 65 k a year. I have no debt and own my car. I'm most likely going to move out of my parents house in a few months. I think it would be best not to buy a house for at least another decade, maybe two, and take out...
