Alright, fellow Instructablers, I need help. I'm not usually a forum-poster; I like lurking. But I'm getting a little desperate. About a month ago, I was in a bit of a car accident. The airbags went off as I was trying to turn away from the telephone pole, and so my right wrist was in front of the steering wheel when the bags went off. This means that my right wrist (yes, I'm right handed) is still recovering, with the current diagnosis of "soft tissue injury with a sprain on top." I'm going to see a hand specialist, but in the mean time, it's quite the wrist brace. Though I can use my fingers, I can't do much without pain/stiffness/etc. So here's the problem that I'm posing to you: what can I make? I'm going stir-crazy. I knit, I woodwork, I play with wire and jewelry making, I draw, I take things apart... I'm willing to learn any new medium and play with any new toys. But I can't use my wrist. So, what adaptive techniques or simple projects or mediums do you suggest until I'm back to full powers? TL;DR: Can't use my wrist, but want to keep making things. Ideas?

Does anybody know of a WiFi Adapter that can work on a Windows XP PC and work with a Dual band WiFi router? (my router is NetGear, if that's important) and that is not $30 or more? I don't care if its used, as long as it works and wont die any time soon (obviously) I've been looking on amazon, I've found a few decent ones and cheap but to be honest... i don't know which to get, which is why I'm asking here to be 100% sure or.. close enough to 100%

I don't have an adapter for it but I want to wire an adapter to the power cord of the camera. The ratings for the camera are 12VDC and 80 mA max. What adapter would I need? How would I wire the power cord to a batery pack? The camera's power cord has a red wire, a white wire, and copper wire around the insulted ones.

My dvd player's ac adapter died, and while your forum on opening it up to fix it was great, it is not a simple short that can be soldered. This is a basic electronics 101 question. The old adapter put out 9v 2.2 a. I have an adapter that puts out 9v 3.0a that fits. Will I fry the dvd player by trying it out? or will it only take what it needs? Thanks for your advice. JB

Hello, I have a HP Smart AC/Auto/Air Combo Adapter, and today it began to fail. To get it to work I have to shake the adapter itself mulitple times, and then it starts to work, and works without a problem. It has only begun to do this occasionally, but it is getting really annoying. Does anyone know what could be wrong with it? Thanks!

Hey everyone! I was wondering, would it be possible to use the head in one of those cassette-to-AUX adapters as a tape reading head? Finding a new magnetic tape head is like hunting for hen's teeth, so it'd be nice if that were an option. Many thanks!

Hi guys, I have been experiencing problems with my Surface Pro adapters (both original and "OEM") where the adapter would power up the tablet but simply won't charge. I decided to probe the connector prongs and found out that the adapter simply outputted 12 volts (and supposedly 2 amps) through the pins. Since both adapters simply supplied 12v to the prongs, can I replace the adapter with a 12v 3a one while keeping the original cable?

I just bought my first real camera. The canon t3i. I want to order an ac adapter for the unit. The one made by canon, is 69 bucks, but i have seen other branded ac adapters for 14.99 of course this raises all kinds of questions, is the canon overpriced? Probably. Is the chaper brand going to harm my camera? I dont know. Maybe some of you can shed light or convince me to buy the OEM ac adapter....

Several months ago, I posted an I'ble for adding an AC adapter to something. The adapter I chose, from Radio Shack, is actually a two-piece "kit" -- the wall wart cord ends in a generic two-pin female jack, and they sell a bunch of different end plugs. The jack is symmetric, so that the end plug can be put on with either ground or hot on the outside.I've just realized that this could be a problem. If the electronic device expects red to be positive and black negative, then putting the jack on backwards would be equivalent to installing all the batteries the wrong-way about. Not a great feature.To "protect" the device, I'm considering adding a diode bridge to ensure that the internal "red wire" always carries the positive, and the "black wire" is always ground. Do more experienced folks consider this a good idea? Is it necessary? Would it be better, perhaps, to just epoxy the end plug so it can't be reversed?

The more I try and understand the nightmare that the shop vacuum hose and adapter issue has become, the more I have to believe Washington was involved in its design. There is apparently no more oversight of this industry than there was over Wall Street and the banks that led to the second great depression... Can someone tell me where a person can find a source that makes real problem solving adapters, and tells you the true inside and outside diameters of both ends instead of contributing to the confusion of this national mystery? Thanks

Hey so I used to use a $30 Dynex Cassette adapter to play my iPod in my tape deck. My deck is a Pioneer KEH-P1010. Anyway, it was a real pain to get it going at first, but then it worked perfectly. I broke the adapter and so I decided to buy a cheap-o $5 "iWorld Cassette Adapter". The three instructions are (literally): 1 - Place the cassette into your car's cassette player. 2 - Insert the audio plug into your iPod®/MP3's headphone jack. 3 - Press play and enjoy your music. Sounds simple enough, right? I've tried it numerous times with my iPod Touch 64gb (same iPod as with the previous adapter) along with my mom's iPod Nano (the newer generation from last year), putting the cassette in both ways (text facing up and down). Each time I try, I can hear the deck spinning as it tries to read the cassette (with a "(---)" flashing on the display), but it always kicks back to the radio. Any thoughts on why this happens or how I can get it to work? A friend of mine had bought the same model (from the same store) and said it worked great (hence my purchasing of it), so I'm sure it should work on some level.

I just realized why computer or plumbing parts are called male and female. The female one is the one you stick something into right? The male one is the one you stick into something. I'm just saying who ever named them must have a weird mind. I realized this when one of my friends made a joke, so please don't say I am perverted.

Hello, by chance could you tell me if possible and replaced the cable from my external hd ultilizando an adapter Bluetooth
Hello, I have an LG GW520 and I have tried everywhere for an adapter to connect this to a stereo. I did find a company that advertised the adapter I needed but when I bought it it is the wrong size as the connection on other LG phones like the cookie models are different :( So basically I need an adapter with a 3.5mm female stereo jack on it. Is it possible to make one?... I've got lots of randoms wires and a headset that fits into the phone with one broken ear bud and a female stereo jack. When I've cut open the broken headset I've got two silver wires, and a purple, red and green wire bundled together and surrounded by fine copper and the female stereo jack has a black, red and brown wire. ....is it possible to connect these and how should I do it? Thanks for reading and I hope you can save my sanity before I just get mad and go an buy another phone that I can connect!

Dear all, I have a Skoda audio system integrated into my Skoda which has a cd reader plus a cd changer, but only a CD button(no AUX available). I would like to stick inside the audio system a Bluetooth receiver so I can listen to music stored in my phone. The goal is to solder a Bluetooth receiver to the audio system without loosing the cd functionality. On top of that I would like to be able to change from one source to the other without having to use an external button like a 3PDT switch. Thanks in advance, Pedro

Some stereos now have female usb sockets built into them to play music from a memory stick. Mine does not, which is why I am looking to make/buy a usb to 3.5mm audio out device that can read the files on my memory stick and output them as audio. I have done a concept picture using professional editing software 'Paint', but the sd card reader is not really that necessary. It could also be battery powered, the picture is just a basic idea of what I want. I have spare computers I could raid for parts if I need. Any help would be appreciated either building or buying such a device, but low costs for both are a big need.

I was wondering if anyone had an idea of making something that could test a laptop charger? It could have all the different sized sockets for all the types of chargers there are and a display for showing the output voltage. We have hundreds of chargers laying around and didn't want to go through the process of testing them all with a multimeter. Any help will be appreciated :) Cheers LukeSC1993

I just purchased a Samsung DigiMax 301 Digital Camera from a friend and he did not have the AC Power Adapter for it. I've looked for a replacement on line but haven't been able to find one. There are all kinds of cheap priced AC Adapters though but I'm not sure which one will work for this camera. The original Adapter is (3.3V 2.0A). I found one at www.goldmine-elec-products.com, that's 3VDC 350ma, would this one work? I have no idea what the 350ma represents so I'm at a stand still on this. Also, would I have to match these specifications, (3.3V 2.0A), exactly? Or could this vary somewhat? Any help would be appreciated!!

Just wondering if there's any downside to re-wiring an AC adapter to run multiple devices. I have 6 of these wall warts near my TV for the following - router - usb hub - phone charger - harmony one charger - clock - PS3 bluetooth/IR converter Most of these run on either 6,9 or 12V. I would be so much cleaner if I can rewire (or splice) a couple of AC adapters to have like two or more outputs. Is there any downside to this? Thanks

Now that I have found this wonderful site I noticed my battery consumption has gone way up. So I figure I could just use an AC Adapter rated for 6V 500mA for constant supply of power while protying, mucking about etc., etc.. Is there anything I should be aware of or is this going to be fine and dandy?

I tore open an AC adapter to find out what I was doing wrong in my own power supply attempts. Before any other components, and connected directly to the outlet prongs, was a transformer. I know that it drops voltage and (by ohm's law) the amperage as well. But how does its survive the process? Why doesn't it have huge amounts of waste heat the way a current limiting resistor does? Why doesn't the primary coil of the transformer--effectively a tiny wire short circuiting an AC outlet--burn up? I'm certain this has something to do with the impedance of an inductor, but I just can't figure out what!

Question by cyc1on | last reply
My title is a simplified version of my problem. I accidentally clicked uninstall instead of disable on my wireless network adapter. I don't have the CD to install it. My WLAN adapter is a Cisco Linksys WUSB54GC Wireless Network Adapter version 3. I've uninstalled the device multiple times but when I reinstall it, it simply says 'The name is already in use or a service display name' and then when I go back to device manager it says the name of the adapter and then a #14 and the next time I attempt to reinstall it, it says #15 then #16 and so on. What I am doing is I'm going to device manager, updating the driver software for my adapter, then clicking 'Let me pick from a list of drivers on my computer' and then clicking 'Have Disk' and choosing the netr system information file. After that, that's when it gives me the name is already in use or a service display name error. I've reset my computer a couple times, searched bing and google a lot and got similar problems but none specific to my situation. Please help, I don't recall trying to install or uninstall in any certain order so my mess there could have corrupted something, maybe. Thanks!
