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%

We're about to break out a new channel for assistive/adaptive tech projects, and other "disability hack" type of Instructables. The big question: what do we call this channel, and what category do we sort it under? Why is this a hard question? Check out the Humana Health by Design contest entries - they include everything from ultra low-tech tools and life hacks to construction projects and full-on techie builds. Perhaps we need more than one channel. If so, how should we divide the Instructables? Do we need one channel for high-tech projects, and one for low-tech? I've been playing with the ideas of "assistive tech" for the high-tech/gadget-based projects to be filed under Technology, and "adaptive tools" for the low-tech/reuse projects and life-hacks to be sorted under Living. These still seem to be arbitrary distinctions, and I'm not sure they make sense. What do you think? Please discuss in the comments, or feel free to send me your suggestions by email/PM!

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?

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

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....

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!

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.
Question by Hadokendude | last reply
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?

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!

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.

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

Hey guys! This is my long awaited first forum topic on my first 2 k'nex creations that I've been wanting to get a topic posted about them for quite a while, but never booked in any free time to get one posted. So today, I've had nothing to do,so I decided to go ahead and post a topic. The guns themselves are quite explanatory. One comes from a traditional firing pin system that's been on the site for ages now. The other gun is also a pin gun, but also has a slingshot mechanism integrated into it. Basically, it's a pin gun that has the ability to be given an unlimited amount of increased power as well as the ability to control pin friction. I give special thanks to Fred the penguin for the original idea. Go look it up if don't know what I'm talking about. That was one concept I used, the other one is really awesome and comes from the mighty 182515. Basically it allows a gun(whatever gun it may be) to be broken down into as many parts as possible, while also allowing a front portion of the barrel to be removable and interchangeable. Both of my guns have this concept. Anyway, enough chit-chat, onto pro's and con's for these weapons: assault rifle- Pro's: -very powerful, breaks oodammo from about 40 or 50 ft, puts holes in drywall, and leaves some very nasty dents in steel doors with certain front ends. -very high range. I can easily shoot a finned tan rod 275 ft. with 3 strong unused #64's and with the tr-18 mounted on it. -extremely versatile. can have multiple uses. - trigger requires no rubber bands and blocks the pins progress every time. -reliable -Doesn't use many pieces,but it uses enough though. Con's: - Gun may be a little hard to fire due to the trigger setup. -uses broken parts. logic bow- Pro's: -extremely powerful. I shot and killed a possum with it using sharpened fin ammo and 20#64's and actually puts holes in steel doors. 'nuff said. -extremely high range. Shoots a finned black rod up to 600 ft. with a tr. And goes up to about 700 with the nar.(Only w/ latex surgical tubing or elastic bungee cord) -extremely versatile. Does the same thing as the rifle. -no pin friction due to the ratchet holding all of the pins bands. -very reliable. -unlimited power. -Like the rifle, the trigger mechanism now operates on no rubber bands. -Trigger guard Con's: - Piece consuming - A little heavy, but nothing too serious. -uses broken parts. Well, that about wraps it up. THESE WILL BE POSTED. I'm just not sure when yet. Below are some pictures for you to drool at. **UPDATE**: I have changed these guns up some after this was published. The rifle pretty much stayed the same, I only did most of the major changes to the logic bow. It now features: A trigger that requires no rubber bands, better body design, bow limb reinforcements, handle moved up to the middle of gun, sear system type trigger or trigger that blocks behind the handle and moves only in one direction, and all the other bells and whistles. I also attached generic/basic stock butts to both guns(lol, that joke is getting old XD). I will upload the new pictures in a few days. Check for updates from me often by the way. I think we're done here. **UPDATE** 10/25/12- I have uploaded the new pictures. The last picture is of a recycled steel can getting pwned by the logic bow. Enjoy. :)

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

I gather that computers that only have ps/2 sockets (no usb connectors) cannot simply use a basic adapter for plugging in a usb keyboard. I have never tried. Would it be possible to create an adapter to allow a usb keyboard to be used with such a pre-usb computer ? I found one arduino project that converted ps/2 to usb and I imagine that to be more difficult.

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!!
