A friend of mine once played her voice mail messages from her phone to mine while we were talking on the cells. Does anyone know how to do that? Please help!!! Thanks

Has anyone built a betavoltaic cell? Tell us about it! I could imagine someone collecting the isotopes from old smoke detectors,painting them onto an old solar cell and making electricity in the dark. I'd try it myself if I wasn't such a lazy old fart.

I have alot of Cordless phones with the handsets and i have the bases, i have answering machines , regular phones. Old cell phones....Is there components in there that i can make a cell phone jammer with? Im teaching myself electronics by taking things apart,lol but i still have trouble figuring out what parts are what. Any help? thanks. Ps, i would love to make one with a altoid tin if possible.

Friends, I hate talking on the cell phone; it's too small, especially when I'm talking from home. I keep a land line so I can chat for hours on a regular sized telephone. However, I'm moving next week and won't be able to spring for a land line. Can anyone help me use an old-time big phone receiver with a cell phone? Blue tooth maybe? Or perhaps attach something to/around the cell phone that allows me to hold it between my head and shoulder and talk into a mouthpiece that's near my mouth? Thank you, evil geniuses, all... xo

Well apparently my mother dropped my cellphone, now when you turn it on, the screen lights up, but it's blank, it vibrates when I turn it on because it was on vibrate before (startup sound). But it won't do anything else, I tried changing the ringer, hitting buttons, and it didn't make any sounds. Display cable popped out? Any ideas? -Punk

I'm looking into getting a cell repeater for my home. I live in a rural area with not a lot of service inside my house, but four bars outside. The repeater I'm looking at uses an omni directional antenna that draws in signal from multiple towers for multiple carriers. My question is, since this system uses an omni antenna, wouldn't any antenna do? Such as a CB antenna? The way I look at it the antenna draws in all types of signal but its left up to the inside receiver what type of signal to use? Am I wrong on this?

I got a new cell phone in the mail, my v220 died (and then came back to life the day I got the new one). So rogers, the cleaver folks, sent me a v360, knowing that's not what I asked for, and the v220 being a $500 something phone, I know for a fact that this one is only worth a few $$ (I would know as my sister has the same one). The buggers eh? But on the the main part, the pictures looked impressive compared to my v220, well on the screen they do. But actually on the computer? Complete shit, you tell me? Ps.- Yea, that's my buddy, holding his new "toy", a water pipe, but lemonie should know exactly what it is.

Solarbotics sell a tiny solar cell. A dollar each, but postage doubles the price.Does anybody know of a cheaper source, preferably in the UK?I have already googled, and failed.Alternatively, is it possible to cut or break up a normal solar cell and still use the fragments?

Hey, does anyone has an instructable on how to make a nano crystalline solar cell? i am currently interested on doing it, but do not know exactly whereto make a good start, especially with the materials. So, can anyone help me out? Thank you very much.

Hi all - new here :) I was trying to think of where I could ask this and I immediately thought of instructables. Does anyone have any ideas where I could find a spray or liquid *open cell* foam? It's easy to find cans of spray closed-cell foam these days, but I've never seen one for open cell foam. I've done a lot of searching, and the only open foam cell solutions I find tend to be giant expensive things for insulating houses in bulk, nothing for small scale applications. I'm looking to fill a bundle of relatively fine tubes (diameter TBD), which I want to act as a sponge on the inside, resisting allowing the liquid inside to drain out while still allowing for gas migration. Hence closed cell is not an option. Polyurethane is probably fine, although other materials may well be fine as well. Any ideas?

Does anyone out there have any idea how to construct a home built wireless cell phone signal booster for the home? I've found a few different brands, but they are way out of my price range. Looking for something that can be built with readily available parts from Radio Shack, Lowes, Home Depot, etc Any ideas? Please submit and thank you!

So, y'know how sometimes you might feel like sharing your music with friends, but you dont want to share you headphones? The solution would be to carry speakers, but usually they're sort of bulky and they wont fit in your pockets very well. So, what about cell phones? even some that are maybe a few years old are still smaller then some speakers. Everyone knows taht cell phones can be Really loud, so what if we somehow add a cable to attach to an audio device, and switch around some things inside, and use the dead phone as speakers?! I would try and do this, but i have no idea how, so this is just an idea for you peoples to think about.!

Lets say I have a solar panel that gives off 5 volts at 30mA. if I were to put a ten ohm resistor in series with it would There be basically no effect because a 10ohm resistor woulkd limit it to half an amp, which is way more. Or does the solar panel act like ~ 167 ohm resistor, and adding a ten ohm resistor will limit it to 28mA?

Does anyone know whether it's possible to re-purpose old cell phones as walkie talkies? I have some "old" phones (1X Tri-mode - 1.9 GHz and 800 MHz CDMA and 800MHz AMPS), and I'd love to be able to use them for our ski club as a short range back channel for communications in addition to the radios we use when we host races. I'm assuming we'd need to get some sort of base station, not sure where or how. There are probably some laws we'd have to comply with, assuming that something like this is even possible (I'm in Canada). I'd consider activating & using them normally, but the cell coverage on our mountain is very weak and unreliable, hence this post. Any ideas on how to get something like this started? Or is it a non-starter?

Hi, I need some help on replacing m batteries for a cordless drill/screw driver. I'm thinking I could us use 4 batteries (3.6 V each battery) t replace the busted battries in the battery pack. I'm just not sure on how to connect thi batteries. Should I connect the on a series from + to - terminals or on a parallel circuit? Thanks!

I occasionally see questions from people wanting to know if they can make their own solar cells.Previously, the answer was "no".Now...The latest issue of Science in School contains a "how to" for making organic solar cells from dyes instead of silicon, that produce useful amounts of electricity.Link to "how to".Also in this issue...The archive of back issues is here (can you find my article?).If you browse the magazine, and like it, you might consider passing the URL on to friends, colleagues and potential advertisers. Previously funded by an EU grant, the print magazine is distributed free. The website is funded until October 2010, but the print magazine needs finance (sound familiar?)Anyway, if you are part of, or know of, a company that would like to target their advertising to science educators across Europe, point them at http://www.scienceinschool.org/advertising or contact them directly at email@example.com

I've always thought that it would be cool to have more than one cell device on my specific account. (no, not like a family sharing plan). Let's say, I want to keep a spare phone in my glove box, on a trickle charger, so that I always have a working phone in an emergency. Let's say you use your cell phone a lot.. Instead of swapping out exhausted batteries, what if you had a second phone on the charger that you can switch to whenever needed. Is it possible to clone your telephone, so that you can have a spare device. If you are paying for the service, and you can only use one of the phones at a specific time, why would the phone company care? I have 6 old phones from which I upgraded. They all work fine, and could make great spares if there was a way of programming them to work on my account. Can the MAC address / serial number be cloned to an old phone? J.

Hello, I want to buy a cellhpone watch with camera. I have a Casio Wristcam WQV-3 but it is broken and had only 0.25 Megapixel ;-) Unfortunaly there are many different models. The descriptions at ebay, dealextreme.com. sonicdigitals.info, eemobi.cn etc. are long but there is nothing about menus/usability, thickness, quality and so on. On youtube a few videos can be found, but not for all models. Maybee someone here has one? "Wishlist": 1.Cardslot, not internal only 2.1,3 Megapixel Cam. Sample Pictures? (Blog, Flickr, Own..) 3.Videorecording 4.Touchscreen 5.Writing/Grafiti, not only virtual keyboard 6.Sketchpad, even with the low resoulution 7.Thin (some are very thick) 8.J2ME or another posibility to write programms German letters would be nice, but optional. Should cost arround $200 incl. shipping+tax to europe or a tad more/less. Unfortunaly so far I could only find the q007 with Java/midp2 support, but it has only 128 MB build in and no extension slot. Thanks in advance!

I'm over 50 and trying to learn how to hack and mod electronic devices. Perhaps this is a dumb question, but so what: I have an old Samsung camera phone that is no longer subscribed to a phone service. It's just a phone, without a smart card. Is there any way to use it as a digital camera, or address book, alarm clock anyway?

From Slashdot:12-year-old William Yuan's invention of a highly-efficient, three-dimensional nanotube solar cell for visible and ultraviolet light has won him an award and a $25,000 scholarship from the Davidson Institute for Talent Development. "Current solar cells are flat and can only absorb visible light" Yuan said. 'I came up with an innovative solar cell that absorbs both visible and UV light. My project focused on finding the optimum solar cell to further increase the light absorption and efficiency and design a nanotube for light-electricity conversion efficiency."Much about his young man is eerily similar to many participants here on Instuctables...SlashdotBeaverton Valley Times storyKatu.com story

I have so many projects going on in my head that I am surprised there is room for anything else. Heck I have plans for a Jacob's ladder, Tesla coil, perhaps a coil gun but who knows. Well for quite some time I have also considered a vibe-bot or whatever you call them, the ones built with pager motors. But since this is not too exciting to some people it is not something I have jumped on doing. But I came up with a new twist today on the vibe-bot that I would like to try. I do not want to give away too many details here because I would like to keep it a surprise if it works. But I do see one possible problem with what I want to do and that is weight. The parts I have already weigh in at 26 grams. I am not sure how much the rest of the parts are going to weigh at the moment. But I was wondering what you think the weight limit for a cell phone motor is. I know that some cell phones can weigh a bit but I have no idea what the weight was for these cell phones since I did not have the scale at the time I tore them apart and would not have thought to weigh the phone anyways. Thank you for your insight.

I'm looking for a way to do simple "on" command for an electronic device. The idea being if I'm on my way home from work and want to use my cell phone to let's say send a text message or email that will go to my computer (probably via a different site) and tell my computer, that I assume will be connected (via usb) to some sort of a relay, to turn on my electric device (say a space heater). I know you can use those timers but I come home at different times each day and would like to a) do it safely, when I'm only 10 mins away as opposed to being locked into the time on a timer) and b) use less energy than I would if say the heater turned on and I was running an hour late. Any thoughts?

Guys, I want to use a strain gauge as a load cell in a driving game, where the brake padal is force sensitive not movement sensitive. Currently the pedal is set up with a rotary potentiometer which has three connections and is basically the same as a PC joystick, complete with the circuit board. The strain gauge is one of the resistive film type with two connections, and the resistance will vary with the extension of the gauge; however, I don't know how to link this to the joystick circuit hardware, as one of the connections is missing Any ideas?

The first manned, hydrogen-powered plane has been successfully tested in the skies above Spain, its makers say.The small, propeller-driven craft, developed by aviation giant Boeing, made three short flights at an airfield south of Madrid, the company said.It was powered by hydrogen fuel cells, which produce only heat and water as exhaust products.The tests could pave the way for a new generation of greener aircraft, the company said.Boeing's chief technology officer John Tracy said the flights were "a historical technological success" and "full of promises for a greener future".Small futureThree test flights of the two-seater aircraft took place in February and March at an airfield at Ocana, south of Madrid. The plane was modified to include a hybrid battery and fuel cell system used to power an electric motor coupled to a conventional propeller. Hydrogen-powered planes have been flown before, but never with a human pilot onboard.BBC Story

I had a cheap phone flasher that I got off ebay, and when its battery died, I dissected the turtle and pulled its blinky guts out. Anyway, it works great for one of my projects, and I want to buy more, but can't find them anywhere. I bought several others off ebay, including more turtles, but they all had different blinkers inside them, which sadly do not work for me. I'm attaching a picture of the part I want. Anybody know where I can get these?

A project I've been trying to do for the longest time is to build a home made speaker phone for my car. There used to be a car phone in it from the pre-cell phone ages and its always sparked my imagination. Basically, from my cell phone's 2.5mm jack to a speaker and to a mic. Now, I have a CB Radio in my Cruiser and it has a built in PA. So what ever I say will come out a 3.5mm jack, very convient for the input for this project. However, I'm a dummy when it comes to speakers. I would have to build a small little loud speaker that would project the sound from my phone. I took apart a headset, so I have the plug for the headset. Now what I don't know is how the wires are arranged in the headset wire and what's the best way to built that speaker from a 2.5mm jack output. The input isn't much of a problem, just gotta figure out which wire in the headset wire is the input... probably red. I'm not much of a electrical guy and I don't currently own a soldering iron. I just have 180w welder.

This question has been bugging me for a while now. What's the difference between a 1.5v AAA cell battery and a 1.5v D cell battery? Why is the D cell bigger? Is that just for weight, or does have more resistance, like it lasts longer? Why is one better? Thanks!

Question about solar cells. Since solar panels are encased in glass or polycarbonate, does exposure to the elements degrade solar cells? And if so, in what fashion? Corrosion of the traces? water infiltration? etc. etc? Or is it a matter of the fragility of the cells?

To be honest, i think it sounds like a good idea. the device would probably have to be about the diameter of an orange, but i bet having a pocketwatch that doubles as a cell phone would be a hit with steampunk lovers! anyone agree with this?

I have a box full of unused cell phones and smartphones. Some were the higher end ones of their time such as Blackberry Storm and HTC Touch. I would like to find ways to repurpose these as they are still good and have wifi and bluetooth capabilities. I was thinking maybe security cameras or robots that can be accessed via the internet to monitor my home and pets while away. Any ideas or links would be greatly appreciated.

Need someone to invent a signal blocker (killer) that cuts the signal when a cell phone is brought near a persons head in a vehicle! Cops are not enforcing the law. People are crashing. Wait till the statistics come out. One in four ? or more! Help, can anyone invent this dearly needed device? Maybe get them installed in all new cars? Now its young people TEXTING and crashing and dying! 3,000 this year from Texting Auto Accidents, they were not accidents, they were stupid texting idiots. lLife is more important than stupid messaging!

I work in a building with a metal roof that is also in a small valley. We have absolutely no reception inside the building. Outside we have about 4 to 5 bars, inside there are none. Maybe one if you are near a window. The building is mainly one large open space on the side. I was wondering if it might be possible to passively "pipe in" cell phone reception. I was thinking of a large antenna on the roof that would be connected to a smaller antenna affixed to the middle of the ceiling of the main room. I know the antennas would need to be tuned to the correct bandwidths and I would need a little help with that. (Our carrier is Verizon in the USA btw). Would this sort of setup be feasible?
