Is it good idea to replace laptop's fan by fan of cooler pad ?

There are nasty fan inside of my laptop. The fan is loud and sound is nasty and works always (its such model of laptop), so I want to remove bottom of the laptop's corpus and may be top of the cooling pad and use the pad instead of internal cooler (which I will plug out). I have AMD. I think that it's may work because: fan inside laptop blows at radiator (which is on another end of copper pipe), not right at place where processors located. And I want big fan that will blow right at those part of cooling system where processors located. I'm not gonna remove copper pipe, just plug out default fan and use pad's instead so that it will blow at cooling system from the bottom. I'm gonna use pad with 220-250 mm fan. What do you think ?

Help making a heating pad

Hi folks, Essentially, I'm trying to make a heating pad and I'm becoming terrible confused. . . Let me start by offering some background on my project. I'm building a fermentation cabinet that will be cooled by a window A/C unit. The cabinet will be split into two halves. The first half, with the A/C unit, will be for lagering beer and cold conditioning. Temps will be around 40° F. The beer fermenting in the second half show be kept at about 60°-70° F.  The 120mm PC fan will turn on and blow cold air into the second chamber when the temperature drops below a set point. I would like to have heating belts wrapped around the containers in the second chamber to bring the heat of the liquid up when it drops too low. This is where I'm getting very confused. I'm basically an idiot when it comes to electrical work. . . I would like to use about 7' of 30 AWG Teflon coated copper wire as my heating element. I've calculated the resistance of the wire at .722 ohms (this is the part where you ought to start speaking up and correcting me). Can anyone help me figure out what type of resistor I would need to drop the voltage down enough to get a 20W heating element? I'm starting with 120V from the wall. The sketch below is the cabinet design. Thanks, Chris

Thinkpad ideas, please.

I seem to have acquired an elderly IBM Thinkpad.  It appears to be fully functional, but... It's running Windows 98, It has a single USB socket, but does not recognise any of the pendrives I plug into it. It has a floppy drive that can be plugged in the side It has no wifi. I have never done anything constructive inside the guts of a computer. So, basically, it's useless to the modern laptop user.  Raw materials. Any ideas?

Is there any free software to tell me the temperature of my laptop?

So my brother sold me his old broken laptop for $7 in quarters! (What a steal right?) So I scrapped the speakers, 2 sticks of RAM, USB ports, a cooling fan, LCD screen, a hard drive, and a diode. So I took the fan and wired it to a USB cable to have a cooling fan under my laptop since it usually runs pretty hot, and now it's nice and cool. Is there a widget or free software to tell me the temperature? Thanks. PS: What else should I do with all these parts? I already installed a RAM chip in my computer.

Wirelessly charged mouse

I need some help from all yall out there. My idea is a wirelessly charged mouse. The mouse pad acts as the transmitter coil, and the receiver is in the mouse. The concept might not be phenomenal for gamers, but would be a step into getting rid of wires on our peripherals and really making wireless charging reality. Perhaps a .2 farad super capacitor (.2 Farads ~ 400mAh) could be used to prevent the mouse from dying if you drag if off the pad for a few minutes. I'd need help conceptualizing it and for those of you who know about electronics, assisting me in designing a schematic. The design would be open source so we can have literally anybody contribute and improve the idea. Leave a reply if you want in!

I need your help! Writers and bored people! Citizen Science: Pens vs. Computers!

I'm conducting a research, and I require all ye's cooperation in this! (Indeed, this is citizen science) If you would like to participate in this tiny research, then would ye lassies and lads care to follow the below instructions? I'll write a high school-level research paper on this once there's so much data, that I'd be swimming in the stuff. If you feel like you can't do it, please do smother the link around liberally, so that other people that can answer it, will answer it! Do your part for science! =========================== Directions: You will need the ff.: > a coin > pen/pencil and paper > a stopwatch of any sort > a word processor (a word count is useful) > an internet connection (for posting the results here, of course!) Then do this: 1) Flip a coin. If heads, you'll be using plain ol' pen-and-paper (well, you could use a pencil, too), but if tails, you'll be doing the WPM's on a word processor. 2) Choose one topic below: > A > My zombie apocalypse survival plan. > B > Windows vs. Linux vs. Mac; which is better and why. > C > Why Am I Even Writing This? (dump your thoughts here) > D > Why I like my favourite movie/novel/whateverart genre. 3) Get your stopwatch, start timing and start writing (in essay form) on your prescribed writing medium (see step 1). There is no time or word limit here, however it is better if something more substantial is to be written. 4) Once you feel that you've completed your thoughts on your written piece, stop the timer and count the number of words you've written. Record the two pieces of info somewhere (I need the time in hh:mm:ss format). . . WAIT: It is recommended that you do the above steps first before proceeding to read and fill out the form in step 5. If you read the form in step 5 first, you will jeopardize the information that the form in step 5 seeks. . . . SERIOUSLY: Do steps 1-4 first, then come back down here. This is science we're talking about here. Well, if you're done with them, then sure, you may pass. . . 5) Copy-paste and fill out the following form (i.e. everything in-between the pluses, including the pluses) and post it in this forum (and delete the stuff in brackets ("[ ]", "< >"), including the brackets themselves), and no, you don't need to post your essays here: ++++++++++ ==|| FORM START ||== Topic chosen: Writing medium: Word count: Time: a) Where do you prefer writing (paper or computer)? If mixed preference, elaborate. b) In what environment did you write in? [i.e. your room, library, outdoors (if indoors, indicate if there was any sun shining through any visible windows or if it was nighttime)] c) How cluttered was your working environment (how messy)? [rate from 1-10 (decimals are accepted); describe how bad/wonderful your working environment was] d) What did you feel while you were writing on your word processor/paper? [how comfortable were you; general emotions] e) Did you encounter any difficulty in sorting out your ideas whilst writing? Please elaborate. f) Did you read this form before you started writing? If yes, why? Tell me. If no, very good! g) Did you fully understand all of the instructions? Don't be shy. kkAATCGx1 ==|| FORM END ||== ++++++++++ Congratulations! You've contributed to science! If you have any suggestions or inquiries (I really feel like I've missed something here), feel free to PM me about it! (I'd really much better prefer PM's over forum posts so as not to clutter up the semi-ultra-subjective data here). All data that is to be posted down here shall be considered open and free to anyone. If you would like to draw your own conclusions, then feel free to grab the data, but make sure to link (or cite) back here! ======================================= Also, despite intending to write a high school-level research paper on this, it's not actually for any research subject. I'm just really bored... and curious. Additionally, is this topic even in the right category? Oh, and belated Merry Christmas and a Happy New Year to y'all!

Magnetic reactive writing pad.

I need help figuring out the best way to do the following. And i have been searching and apparently I don't know the proper way to phrase this to find the information on google/instructables. What I need -  a small surface that is magneticly reactive, to be able to Write with a magnet. It also needs to be able to be erased, probably also with a magnet.  I want it to be decently small, and I am sure there is material out there, but i don't know what it is.  And no I dont want a dry erase board.  Think of the Magnadoodle, where it would react to what is being drawn with the magnet, but i wnat something that is more like a Slate, and not a series of pockets that have a certain amount of filaments that react to the magnet.  I am sure there is some kind of material like this out there. I just dont know what to call it, and i need to be able to make it decently small and thin.  A basic idea, is like an impression pad. If you wrote something on the top sheet, or a couple of sheets of the pad, under the sheets, it would take an impression of it, (assuming it was written with a magnetic pen), you could then see what was written on the sheet originally, on the surface. Also it would need some way to be erasable so it could be used again.  A concept like carbon paper, but with magnets.  Please point me in the right direction, I am very hands on, and a long term DIYer, i just need to know what basic material i need to accomplish this. I know it exists, i just don't know what to call it.

How to Power an AC device using DC- from an outlet

I have a heating pad (Sunbeam, the kind of pad used for muscle aches etc.) that plugs into the wall (110v AC). It says on the pad that it draws 42watts. For various reasons, I'd like to have the heat generated by a DC source rather than AC.I'm thinking maybe there is a way for me to plug some kind of converter into the wall (AC to DC) and then plug the heating pad into this which will still result in heat. I have no idea if this is possible. The pad has a switch for three different heat settings.Can I do this? How?Thanks for any suggestions!

NEED HELP! - Boxing Pad Man w/ Programmable Lights array?

I had an idea... Since I cant go to training for a while, I wanted to build my own Pad Man! haha (well thats what I'd call it.) The idea is, I would mount pads on a metal frame (which would be drilled to the wall) and I would hit the pads... Lights would light up next to each pad in which combo I need to hit, (on a timer so the lights would show up then I have 3-4 seconds before the next combo) and it would be random... (even better than that would be having audio go with it, saying numbers) I know physically this would be possible (ie, the pads and the frame) but could I program the lights and the numbers with some sort of mini circuit board?? Thanks for the help guys, would be a wicked build I would even put a video up of it working! I think I will start on the frame and pads, and will try and google something for the light array but I really have no clue where to start (not really done anything like that before.) So Please oh wise instructables!! Show me the way!!

DIY Drum Pad that Controls MIDI Device (Korg nanopad)

Hi all, I'm working on a project which involves a pipe like structure with something like a DIY electronic drum pad on top. (like a stand alone drum) When the pad is hit it, triggers a key on a MIDI device such as the KORG nanopad http://korg.com/Product.aspx?pd=415 under the actual drum itself. This nanopad acts as a remote control for tracks created using music software on my laptop. So when the pad is hit, it starts a track. Problem is, I have no idea how I will make the connection from the pad to the MIDI device. I was thinking about using a Peizo signal but am lost as to how to wire it up or if thats possible. If I use this instructable https://www.instructables.com/id/Electronic-Drum-Pad/ should I be able to simply solder the Peizo wires into the nano keypad relatively easily?  Long shot but if anyone has even the slightest idea what I'm getting at here, any help would be greatly appreciated. Thanks!

Create inexpensive hail pads - Citizen Science Contest

The SciStarter Citizen Science Contest is live! This is your opportunity to help millions of citizen scientists contribute to real scientific discovery. Make their experiences better by coming up with solutions to some real annoyances that hinder their participation. To get you started, here is a specific--and very real--challenge sent to us by project organizers. CREATE INEXPENSIVE HAIL PADS Background: The Community Collaborative Rain, Hail, and Snow Network (CoCoRaHS) volunteers take and submit measurements of rain, hail, and snow precipitation. These observations are made available for use by the National Weather Service, meteorologists, emergency managers, and others. The Problem:  Hail pads are essential to CoCoRaHS's mission to measure, map, and study hail. Each pad consists of a 12" by 12" square of Styrofoam covered in Heavy Duty Aluminum foil. However, in recent years, these materials have tripled in cost, which has greatly reduced the number of hail pads that can be produced and distributed. The Challenge: Create a cheaper hail pad that can measure the number, size, and orientation of hail stones. Enter now! Contest closes January 21, 2013

Goalie Designs New Pads to Block More Shots

Hockey goaltender Trevor Leahy was looking for an extra edge in his hockey games and decided to design some new goalie pads to help him out. Going with the idea of camouflaging them, the front of the pads are meant to mimic the look of the net itself. The idea is that in the split second before a shot, a player would shoot into the pad and not the real net. The results are inconclusive, but at least the whole process has helped Trevor get into college.Since the days when Boston Bruins' goaltender Gerry Cheevers started inking stitches onto his mask each time the equipment protected his face, many goalies have expressed their individuality with designs and paintings on their mask or other pieces of equipment. But Leahy's design - essentially a camouflage for a goal that is 4 feet high and 6 feet wide - has hockey players and coaches amazed and impressed. Link via Core77

Idea - DIY Heated Jackets (Need help)

I just came across a website selling heated jackets (http://www.brookstone.com/shop/product.asp?product_code=WOMENS_HEATED_JACKET&cm;_ven=Compare&cm;_cat=ChannelAdvisor&cm;_pla=msn&cm;_ite=datafeed) and I started thinking it wouldn't be hard at all to make something like this. It needs three heating pads, one larger one on the upper back, and two smaller ones centered over each pectoral. Seems like it would be a good idea to have to power lines run to a battery pack in the front that could be removed and recharged (would probably also toggle the power for the jacket). And of course you could probably build in a wall plug option. ANYWAY! Does anyone know of any small, electrically powered heating pads? Or (cheap) devices with such pads in them? I found a heated cushion seat for roughly $60, but Brookstone charges roughly $200 for the jacket and $60 for one pad (even the larger back one) isn't economical. Thanks for reading,JM

Bilge Pump vs Drip Irrigation for Low-Power Swamp Cooler

I'm building a small evaporative/swamp cooler for Burning Man that I would like to use as little power as possible (no solar panels). Traditional playa swamp cooler designs use a small pump to continuously irrigate the cooler pads. I'm thinking it might be more efficient to put the water in a reservoir that sits above the pads and gradually drips down on them. But since the pads need to be saturated for maximum evaporation, eventually the water will pool at the bottom and need to be pumped back to the reservoir by a pump controlled by a float switch. Which of these designs do you think would use less energy?

switching on a device using a mcu

I just want to know, I have a device (a gravis game pad pro) that continuously sends out a 3 byte serial packet via 2 wires (the game pad drives the clock, so the mcu is the slave, the clock is at 20khz), but there isn't any chip select or slave select or anything like that to start the serial transmit, and since my application circuit already has another serial device on connected to the spi pins of my PIC, I can't have the game pad on all the time, so I decided I need to control when to power on the game padwhat should be used (that i have on hand right now)?a switching regulator like the TC110 from microchip? (i don't have this one yet)a mosfet driver (i have lots of tc4424)?2n3904 or 2n2222 or bc547 transistor?EDIT: I'm just gonna use the mosfet driver... But what is the proper way to do this?or waste some program space and manually interpret the clock and the data pins? there is always five consecutive "1" in the first byte of data, and that condition can never be repeated

Li-ion 5 pin, pinout?

Good Day Fellow TinkerersI have a battery that came out of a Android Tablet that i want to use for another project.It has a cuircuit board attache to the top which i would assume is a over/under charge protector and it has 5 wires coming off of that. 2 x Red, 1 x White and 2 x Black.The two black wires are connected to the same pad on the "protection circuit" and the two red are connected to the same pad. The white wire is on a separate pad i.e. 3 pads, 1 with 2x red, 1 with 2 x black and 1 with 1 x white.I figure the Red would be positive and the Black negative and then i would assume that the white is the Thermistor connection.My Question :How do i connect this externally from the tablet to charge? I figure red and black are the usual, but how do i connect the white wire?Thanks in advance for any help :)

Xbox 360 Keeps Shocking Me, New Mouse Pad Is Making Cursor Twitchy

Whenever I touch my Xbox 360 after playing it for a while, it shocks me. It's really fucking annoying. It hurts too. It's made my finger go numb at the tip a couple times. I put a piece of a static cling fridge calender over the drive eject button, and that works most of the time, but any time my finger is a little bit off the piece of plastic and touches the Xbox, it shocks me. It gets me if I touch a thumb drive I've had in there a while too. I think it might have something to do with me not being grounded to the console via a controller wire, because my controllers are wireless, unlike my GameCube ones, which I would never (or rarely maybe, I dunno) get shocked from. I have another problem too, I have this mouse pad with a wrist rest, but the mouse pad part of it is fabric on top, and always catches hairs and dirt and stuff, so I cut it off. I have the wrist rest taped to my keyboard tray now where it would normally be, but I'm using a Dell mouse pad that came with my computer. The problem is, ever since I've started using it (yesterday) my cursor has been twitching, anywhere from a few centimeters to going all the way to the edge of the screen. This happens constantly, probably once a minute. This is also driving me crazy. I've heard that having a mouse pad with colours and stuff like that all over it can make optical mice twitch. The one I'm using now is just different shades of grey, I don't think it should be this bad.

Laptop Cooling Pad

I'm using a laptop-sized, vented, inverted vegetable tray to keep the laptop cool. It's quite effective even without any fans in this scorching heat. I added a CPU fan underneath ( 12 V, 0.42 A), and ran it off a USB cable from the laptop. The air is quite nice, but one thing I'm a bit worried is, when I touch the top of the laptop, it slightly vibrates constantly due to the fan underneath. Is that dangerous for the laptop? I'm planning to add another fan beneath the hard disk. The one I have now, is under the laptop's CPU fan. Another thing I would like to know is that, is it okay to run two fans of 042 A each, from two USB ports? Each USB port can supply 0.5 A max current. Running one fan off each port should be okay? But, today, the temperature was quite high in the afternoon, nearly 50 degrees! I'm thinking of buyin a readymade laptop cooler.  One of these three cheap ones at ebay India: http://cgi.ebay.in/Folding-Chill-Pad-Stand-Laptop-Cooler-Cooling-2-Fan-/250631119144?cmd=ViewItem&pt;=LH_DefaultDomain_203&hash;=item3a5ac76128 http://cgi.ebay.in/Chill-Pad-Stand-Laptop-Cooler-3-Fans-USB-Fan-LED-Light-/250629679857?cmd=ViewItem&pt;=LH_DefaultDomain_203&hash;=item3a5ab16af1#shId http://cgi.ebay.in/New-Super-Mini-2-Fan-Foldable-Laptop-Cooling-Cooler-Pad-/280504780978?cmd=ViewItem&pt;=LH_DefaultDomain_203&hash;=item414f6348b2 Please advise / comment.

Recieved my samples from TI.com today, expecting DIP or at least SOIC packages. The parcel was a thick 9x9 inches with loads of padding and each chip was in a tiny plastic case inside a folded bag, inside enother bag inside an antistatic bag and wrapped in padding and card. Bit unnecessary when you see the size of these chips, as you can see in the pictures, the chips are 4-5mm squared. Has anyone here soldered one of these packages? I don't think I stand a chance, bad eyesight and a crap soldering iron :/

Hamster's heating pad

The winter is on it way. I'm having a hamster, a winter white, but the last winter his caught cold and it cost very much for him to cure him. I don't want my hamster to be sicked any more, so I made a heating pad for him. I used this instructable  https://www.instructables.com/id/DIY-heated-clothing/ and I found it is very well. I use a two - meter 26 - gauge wire, and it only result in a 0.15 ohm resistance. With an 1.5 v voltage, It work well and i need a 10a fuse to protect this circuits:) But last week it overheated and my hamster was burned, quite bad. I'm wondering if there is a solution to this. Would you mind giving me a circuit in which: - there is a thermistor to sense the temperature. - If the temperature is to high (30 celcius degrees ), it gives a relay some voltage and the relay breaks the heater circuits. - And it component should be popular, cause I'm a kid and don't have many time go round n' round to find them. Me and my hamster will very appreciate your kindness. Thanks all.

Sadly I'm doing a change of plans for Free Comic Book Day instead of being a Trekkie there I'm gonna be as a Super Saiyan with the V1 armor on without those huge shoulder pads I just need ideas on what I should use to create this Armor to go with my Blue Lens Scouter I've bought from ThinkGeek. What kind of Foam or material that is strong and sturdy to withstand me moving around in. I'll gather up the list once I have the main base of what I should use to make this.

GoodGuide

GoodGuide is a cool website I discovered via Web 2.0's Launch Pad (which Instructables was a part of in 2006). It ranks various products on Health Performance, Environmental Performance, and Social Performance. See how good or bad your soap is for you, the environment, and the workers who produce it.

Sky Lantern

Has anyone built anything like this, or know of an instructable that could help to design something like these floating, hot air balloons that are popular in Thailand?I am looking for, in particular, the method of obtaining or creating the fire-proof paper or fabric that is used for the balloon itself. Also of interest is the object at the opening of the balloon that is lit and provides the heat. It doesn't look like a small candle, like I thought it might be. But rather, it's a small pad, about the size of a note card (3x5") that is flammable and completely burns. I think I could figure out the metal loop and bamboo skewer cross-bracing that holds the base of the balloon open and that holds the lit pad in place.You may send responses to my email, as well...uncleplayground (at) yahoo (dot) comThanks!Sky Lantern

Calculator data into a PC

I have a Check and Correct Calculator with 120 steps, I need to upload the data stored on the memory of the calculator, I mean the 120 steps all together into a excel file, or to a text file. Any ideas on how to convert a calculator into a small pad?
