adaptive making

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?

Need a WiFi Adapter Answered

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%

AC Adapter - wrong amperage?

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

help powering breast pump from ac adapter? Answered

Electricity for the challenged

I have a US plug AC/DC power adapter and need to get a European version. The specks on the adapter are input: 120VAC 60Hz 24 W and the output: 10 VDC 1400mA. I really don't have a clue as to what all these numbers mean but understand at a bare minimum I need something with a 10 VDC output. I've looked around at some shops and can find adapters that say 9v 1000mA and others that are 12v 1500mA. Do I need to get the exact voltage (I presume the v stands for volts)? What about the amperes ( I believe that mA is some increment of amperage)? Can I fudge the numbers a bit to save money and time instead of trying to get the exact configuration of the original adapter? Thanks for any help in clarifying this for me.

iPod Cassette Adapter Help?

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.
